Preferably, the upper surface of the support ring 102a-2 is provided with a resting groove 102a-21 fitted to the bottom of the support leg 102b-1, and the bottom of each support leg 102b-1 rests in the corresponding resting groove 102a-21, preventing the support leg 102b-1 from sliding or misplacement, improving the stability of the structure.

Therefore, the support assembly 200 of the present invention can be stably mounted on the base 101 through the lifting mechanism 102 and the guide 103, and the mounting process is as follows:

firstly, placing the base 101 on the ground, wherein the slot 101b faces upwards;

secondly, inserting the guide post 102a-1 of the support seat 102a into the slot 101b, and enabling the convex strip 102a-11 to be aligned with the guide groove 101b-1 and slide in;

thirdly, preliminarily screwing the screw rod 102c-1 of the lifter 102c into the screw hole 102a-12 on the guide column 102a-1, and enabling the screw rod to temporarily not completely penetrate through the screw hole 102 a-12;

fourthly, the support frame 102b is placed on the support ring 102a-2, and each support leg 102b-1 is ensured to be embedded into the corresponding placing groove 102 a-21;

sixthly, the handle 102c-2 is held by hand to rotate the screw rod 102c-1 to enable the screw rod to downwards and completely pass through the screw hole 102a-12 until the spherical surface 102c-11 at the lower end of the screw rod can be embedded and supported in the spherical groove 101 b-2; then, the screw 102c-1 is rotated continuously, and since the screw 102c-1 cannot move downwards continuously thereafter, the reverse drive support seat 102a is slid upwards along the guide groove 101b-1 as a whole; the supporting seat 102a sliding upwards can lift the supporting frame 102b and the upright 201 upwards, meanwhile, each pull rod 202 is gradually tensioned, and each inserting block 203 is tightly inserted into the corresponding inserting region 101a-1 due to the inclined pulling effect and cannot be separated from the inserting block, so that a final stable state is formed, and the installation process of the supporting component 200 on the base 101 is completed.

Further, the guide 103 of the present invention may be integrally formed on the support platform 102b-2, or may be provided separately from the support platform 102 b-2. When the guide member 103 is separated from the supporting platform 102b-2, the guide member 103 passes through the supporting platform 102b-2, and the supporting platform 102b-2 is provided with a through hole for fitting the guide member 103.

Further, the inclination angle of each blade 500 of the handpiece can be uniformly adjusted, so that the process of manually adjusting the pitch can be realized according to actual requirements. The specific technical scheme is as follows:

the handpiece comprises a transmission assembly 600 which is in transmission connection with each blade 500 and can uniformly adjust the inclination angle of each blade 500, and a driving assembly 700 which can drive the transmission assembly 600 to rotate. The housing 400 has an accommodating space therein. The drive assembly 700 preferably extends beyond the structure of the housing 400 and can be manually adjusted. After the inclination angle of the blade 500 of the machine head is adjusted, the machine head can be driven to rotate by the head-on wind, so that the rotating torque is transmitted to the power generation mechanism 302 connected with the machine head through the rotating shaft Z, and the mechanical driving power generation is realized.

Specifically, the inner end of each blade 500 is fixed with a first bevel gear 501 and inserted into the accommodating space of the housing 400, and the outer end of each blade 500 extends out of the accommodating space.

The transmission assembly 600 is disposed in the accommodating space of the housing 400, and includes a driving shaft 601 extending axially and a second bevel gear 602 fixed on the driving shaft 601, wherein the second bevel gear 602 is engaged with each first bevel gear 501 for transmission, so that when the driving shaft 601 is rotated by an external force, the second bevel gears 602 rotating synchronously can drive each blade 500 to rotate to change the inclination angle of the blade 500.

The driving assembly 700 is connected to the driving shaft 601 and can drive the driving shaft 601 to rotate around its own axis. Therefore, the blades 500 can be controlled to uniformly adjust the inclination angle by rotating the driving assembly 700, so that the pitch variation is realized.

Further, the housing 400 includes a containing shell 401, and a front end cover 402 and a rear end cover 403 detachably connected to two ends of the containing shell 401, which together enclose an inner containing space. The invention sets the following steps: the "front" in the present invention corresponds to the windward direction of the nose, and the "rear" corresponds to the overhanging direction of the tail 303.

The interior of the housing shell 401 has a pitch chamber 401a, and the pitch chamber 401a provides a space for the connection and transmission of the first bevel gear 501 and the second bevel gear 602. The outer side wall of the containment shell 401 is provided with a fixing location 401b corresponding to each blade 500, each fixing location 401b communicating the pitch chamber 401a with the external space. Preferably, the fixing portion 401b may be a sleeve-shaped structure integrally formed on the housing shell 401. The root of each blade 500 is provided with the spacing section 502 that cooperates in fixed position 401b, and spacing section 502 is for cooperating the ring channel in fixed position 401b internal diameter, and each blade 500 can be installed on the fixed position 401b that corresponds through spacing section 502 interlude, realizes spacing and fixed. The rotation axis Z is fixed to the outer surface of the rear cover 403 in the axial direction, and is preferably integrally formed on the rear cover 403.

Further, the drive assembly 700 includes a drive cap 701 rotatably coupled to the front end cap 402, and the drive cap 701 may be an axially extending stub structure.

The outer end of the driving cap 701 extends out of the front end cover 402 for manual operation and twisting; the inner end of the driving cap 701 is provided with a concave adapter port 701a, and the cross section of the adapter port 701a is square.

The driving shaft 601 comprises a cylindrical section 601a and a square column section 601b, any cross section of the cylindrical section 601a is circular, any cross section of the square column section 601b is square, and the outer diameter of the circle is not larger than the side length of the square. The second bevel gear 602 is fixed on the cylindrical section 601a, and the square cylindrical section 601b is located at the front end of the cylindrical section 601a and is inserted into the adapter port 701a to form a fit. Therefore, the square column segment 601b can slide linearly in the axial direction relative to the adapter port 701a, but cannot rotate in the circumferential direction relative to the adapter port.

The inner side wall of the rear cover 403 is provided with a rotation fixing position 403a, the rotation fixing position 403a is an annular structure which is opened inwards, and the rear end of the cylindrical section 601a is fixed inside the rotation fixing position 403a through a bearing C, so that the driving shaft 601 can rotate.

Further, a ring-shaped locking ring 401c is fixed (integrally formed) to the front end of the housing case 401. The interior of the annular locking ring 401C is provided with an annular cavity 401C-1, and the front end of the annular locking ring 401C is provided with an annular socket 401C-2 communicated with the annular cavity 401C-1, so that any longitudinal section of the annular locking ring 401C is of a C-shaped structure with an opening at the front end.

A plurality of limiting grooves 401c-21 with the same specification are uniformly distributed on the inner side wall of the annular socket 401c-2 along the circumferential direction, each limiting groove 401c-21 is a through groove with two axially extending ends, and the limiting grooves are densely distributed on the inner side wall of the annular socket 401c-2 to form a circle.

Meanwhile, the driving assembly 700 further comprises a limiting ring 702 fixed on the periphery of the inner end of the driving cap 701 and a plug-in ring 703 corresponding to the annular socket 401 c-2. The limiting ring 702 is an annular baffle plate which is axially vertical to the driving cap 701; the plug ring 703 is a sleeve structure engaged at the end of the stop collar 702, and can be inserted into the annular socket 401 c-2.

The outer side wall of the insert ring 703 is provided with a limit protrusion 703a which is matched with the contour of the limit groove 401 c-21. The retention bump 703a can be inserted into any of the retention grooves 401c-21 such that the bayonet ring 703 (i.e., the drive assembly 700 as a whole) cannot rotate circumferentially relative to the annular locking ring 401 c. In addition, the end of the docking ring 703 can also extend from the annular socket 401c-2 into the annular chamber 401c-1, so that the spacing protrusion 703a is misaligned and disengaged from the spacing groove 401c-21, thereby enabling circumferential rotation of the docking ring 703 (i.e., the drive assembly 700 as a whole) relative to the annular locking ring 401 c.

Therefore, whether the driving assembly 700 can rotate relative to the annular locking ring 401c can be indirectly controlled by controlling whether the position-limiting protrusion 703a and the position-limiting grooves 401c-21 are staggered or not; since the driving assembly 700 is integrated with the driving shaft 601, the relative circumferential rotation cannot occur, and therefore, the process of driving the driving assembly 700 to drive each driving shaft 601 and each blade 500 is finally realized.

Preferably, a plurality of limiting protrusions 703a corresponding to the number and distribution positions of the limiting grooves 401c-21 are uniformly distributed on the outer side wall of the plug-in ring 703 along the circumferential direction. The limiting protrusions 703a are semicircular protrusions which are continuously arranged and are mutually connected end to end, and the outlines of the limiting grooves 401c-21 are complementary with the semicircular protrusions.

Further, the driving assembly 700 further includes a reset member 704 disposed between the limiting ring 702 and the annular locking ring 401c, and the reset member 704 is a compression spring.

In the initial state, the drive assembly 700 is pressed against the inside of the front cover 402 when pressed by the reset piece 704; at this time, each limit protrusion 703a of the plug ring 703 can be just inserted into the corresponding limit groove 401c-21, so that the driving assembly 700 cannot rotate as a whole, and the driving assembly 700 does not have a driving adjustment function for the driving shaft 601 and each blade 500. And this state can be maintained stably by the pressing of the restoring member 704.

When the exposed driver cap 701 is manually pressed by an external force, the insert ring 703 can gradually slide inward over the annular socket 401c-2 and extend into the annular chamber 401 c-1; therefore, the limit protrusion 703a forming the dislocation and the limit groove 401c-21 do not have circumferential rotation restriction; at this time, the driving cap 701 may be manually rotated to drive the driving shaft 601 to rotate, and the second bevel gear 602 on the driving shaft 601 may drive the first bevel gears 501 to rotate in unison, that is, drive the blades 500 to rotate, so as to change the inclination angles of the blades 500.

After the blade 500 is adjusted to the desired pitch angle, the driving cap 701 is slowly released and a slight attempt is made to rotate the driving cap 701 slightly so that the limit protrusions 703a thereof can be inserted into the nearest limit grooves 401c-21, and finally the initial stable state is restored again by the restoring action of the restoring member 704.

In summary, the blade 500 of the present invention is convenient to adjust the inclination angle, and the uniform adjustment process of the inclination angle of each blade 500 can be realized only by pressing and rotating the driving cap 701. The blade 500 of the present invention is preferably drop-shaped in cross-section and its pitch angle is adjusted primarily to adjust the angle of its outer side with respect to the direction of the wind.

Further, the inner ring of the annular locking ring 401c is provided with a guide part 401 c-3. the guide part 401c-3 comprises an annular partition 401c-31 which is integrally connected with the annular locking ring 401c in an engaging manner and a first sleeve 401c-32 which is sleeved on the periphery of the driving shaft 601, and the annular partition 401c-31 is connected with the first sleeve 401c-32 in an engaging manner to form an annular structure with a longitudinal section of L.

The ends of the first sleeves 401c-32 extend to the front end of the second bevel gear 602, so that the drive shaft 601 can maintain a stable spatial position and can only rotate by itself under the restriction of forward and backward clamping of the first sleeves 401c-32 and the rotation fixing positions 403 a.

The restoring member 704 may be disposed between the retainer ring 702 and the guide member 401 c-3. in this embodiment, one end of the restoring member 704 is fixed to the retainer ring 702 and the other end is fixed to the annular partition 401 c-31.

Further, the rear end of the annular locking ring 401c is provided with a stiffening rib 401c-4 for improving the structural strength of the annular locking ring 401 c.

Further, the edge of the front cover 402 is detachably connected to the front end of the housing case 401 by a bolt L, and a passage 402a fitted to the driving cap 701 is provided at the center of the front cover 402 to facilitate the penetration of the driving cap 701.

The inner port of the passage 402a is provided with a second sleeve 402b fitted to the outer diameter of the driving cap 701; the limiting ring 702 is pressed by the reset piece 704 and can abut against the inner end of the second sleeve 402b, and at this time, each limiting protrusion 703a can be completely embedded into the corresponding limiting groove 401 c-21.

Further, the edge of the rear end cover 403 is detachably connected to the rear end of the accommodation case 401 by a bolt L.
