In addition, since the shoulders of the persons are different in height, a height-adjustable stool (not shown) is placed on the bottom plate 32.

Further, the insertion mechanism comprises a fixing column 4 fixed on the fixing plate 3, at least one circle of limiting part is axially arranged on the side wall of the fixing column 4, the limiting part comprises a plurality of limiting blocks 5 arranged on the circumferential direction of the fixing column 4, and the limiting blocks 5 are connected with the fixing column 4 through first elastic pieces 6. Specifically, the method comprises the following steps: seted up the first recess 7 of several on the lateral wall of fixed column 4, stopper 5 sets up in first recess 7 through first elastic component 6, and stopper 5's straight face sets up towards fixed plate 3. When the fixed column 4 is inserted into the fixed hole 2, the limiting block 5 is compressed into the first groove 7 until the limiting block 5 is popped out to reset, so that the fixed plate is fixed. It should be noted that: the fixed orifices 2 can be through-holes which run through the backboard 1, when the limiting blocks on the fixed columns stretch out of the fixed orifices 2, the limiting blocks are popped out, the straight surfaces of the limiting blocks are abutted against the back surface of the backboard, and therefore the fixing of the fixed plate and the backboard is realized. Certainly, because stopper 5 is provided with many rings on the lateral wall of fixed column 4, consequently, can continue to press the fixed plate according to the thickness of different people's shoulders, make fixed column 4 continue to insert towards fixed orifices 2 in, the straight face of the stopper of different positions on the fixed column offsets with the back of backplate to make the fixed plate can adapt to different crowds. In addition, a limiting groove matched with the limiting block can be arranged on the inner wall of the fixing hole 2, and when the fixing column 4 is inserted into the fixing hole 2, the limiting block 5 is positioned in the limiting groove, so that the limiting block is limited, and the fixing plate is fixed on the back plate; when the fixing plate is continuously pressed, the limiting blocks positioned at different positions on the fixing column can be limited in the limiting grooves, so that the fixing plate is fixed on the back plate.

Further, in order to withdraw from the fixing hole or take down the fixing column, the fixing column 4 is hollow, one end of the fixing column is open, and the open end of the fixing column is fixed on the fixing plate 3, meanwhile, a first through hole 31 communicated with the inside of the fixing column 4 is formed in the fixing plate 3, the first groove 7 is not communicated with the inside of the fixing column 4, namely the thickness of the first groove 7 is smaller than the wall thickness of the fixing column 4, a second through hole 8 is formed in the side wall, facing the inside of the fixing column 4, of the first groove 7, and the second through hole 8 is communicated with the inner cavities of the first groove 7 and the fixing column 4. A control piece for controlling the retraction and release of the limiting block 5 is arranged in the fixed column 4.

Specifically, the method comprises the following steps: the control piece comprises a control rod 9 inserted into the fixing column 4 through a first through hole 31, a screwing head 10 is fixedly arranged at one end of the control rod 9 extending out of the fixing plate 3, a string (not shown in the figure) is arranged on the bottom surface of the limiting block 5, and the string penetrates through a second through hole 8 to be fixed on the side wall of the control rod 9. The control rod is rotated through the screwing head, so that the string is wound on the control rod, the limiting block 5 is gradually pulled into the first groove 7, the limitation of the limiting block on the backboard or the limitation of the limiting block in the fixing hole is removed, and the fixing column is successfully pulled out or taken out of the fixing hole.

Furthermore, since there are a plurality of insertion mechanisms, the restriction of the stopper cannot be released simultaneously when the lever is operated, and thus, when the stopper is compressed into the first recess, the state needs to be maintained continuously. Therefore, a cylindrical hole 11 is formed in one end face, extending into the fixed column 4, of the control rod 9, the cylindrical hole 11 is coaxial with the control rod 9, an expansion sleeve 12 is arranged in the cylindrical hole 11, the other end of the expansion sleeve 12 is fixed to the inner bottom of the fixed column 4, the expansion sleeve 12 is composed of two sleeves, a small-diameter sleeve is fixed to the inner bottom of the fixed column 4, and a large-diameter sleeve is fixed to the cylindrical hole 11. Of course, the cylindrical hole 11 itself can be used as a sleeve, and a small-diameter sleeve can be directly placed in the cylindrical hole 11, so as to form a telescopic sleeve. The object of the present invention can be achieved in any manner.

Further, on the terminal surface of control lever 9, around the first limiting plate 13 of cylindricality hole 11 equipartition several, the interior bottom of fixed column 4 is provided with the second limiting plate 14 that the several corresponds with first limiting plate 13 around its center department, and second limiting plate 14 sets up around the minor diameter sleeve promptly, and sets up apart from the minor diameter sleeve. When first limiting plate 13 inserts in the second limiting plate 14, realize the fixed to the control lever 9, avoid under the effect of first elastic component 6, stopper 5 pops out, can't succeed in taking out the fixed column from the fixed orifices. The number of the first limiting plate and the second limiting plate can be set according to actual needs. And the telescopic sleeve 12 that sets up is mainly for fixing a position the control lever, makes the first limiting plate on the control lever can accurately insert the space department between the second limiting plate, and simultaneously, telescopic sleeve 12's setting also can not influence the rotation of control lever. It should be noted that: the second limiting plate 14 is provided with various modes, and the second limiting plate 14 can be directly fixed at the inner bottom of the fixing column; a cylindrical groove can be formed in the inner bottom of the fixed column, and the second limiting plate 14 is fixed in the cylindrical groove; or the shape of the second limiting plate is directly dug out at the inner bottom of the fixed column 4, so that the second limiting plate and the fixed column are integrally formed.

Furthermore, because the control rod has certain length, after one end in the fixed column is fixed through the limiting plate, the limiting plate is easily broken under the combined action of the first elastic pieces 6. Therefore, both ends of the control lever are restricted. Namely, a plurality of first clamping plates 15 are arranged around the control rod 9 on the side face of the joint of the screwing head 10 and the control rod 9, a plurality of second clamping plates 16 corresponding to the first clamping plates 15 are arranged around the first through holes 31 on the surface of the fixing plate 3, and when the first limiting plate is inserted into the gap between the second limiting plates, the first clamping plates are also just inserted into the gap between the second clamping plates, so that the two ends of the control rod are fixed. Certainly, the clearance between two adjacent second cardboard 16 corresponds with the clearance between two adjacent second limiting plates 14, and first limiting plate 13 is the same with first cardboard 15 quantity, and second limiting plate 14 is the same with the quantity of second cardboard 16, just can realize fixing the both ends of control lever.

Further, in order to limit the position where the string is wound on the control rod, an annular groove 33 is formed in the side wall of the control rod 9 at a position corresponding to the second through hole 8, for the height of the annular groove 33, when the first limiting plate 13 and the second limiting plate 14 are fixed in a staggered manner, as shown in fig. 4, and when the first limiting plate 13 and the second limiting plate 14 are separated from each other, as shown in fig. 7, the limiting groove 33 always corresponds to the second through hole 8, so that the string can be wound in the annular groove all the time no matter the control rod is in a fixed state or in an unfixed state.

Furthermore, in order to increase the comfort when the fixing plate contacts with the human body, an elastic cushion 17 is arranged in the middle of the plate surface of the fixing plate 3 between the two fixing columns 4, shoulder protection cushions 18 are arranged on two sides of the elastic cushion 17 and the fixing plate 3 in a sliding manner, and the center of one side of each protection cushion 18 is arranged in a concave manner. The shoulder protection pad 18 is configured to be movable to accommodate people of different ages and sizes.

Specifically, the method comprises the following steps: be located two sides of cushion 17, be provided with bar groove 19 along its length direction on the fixed plate 3, bar groove 19 sets up along 3 length direction of fixed plate, and is located the intermediate position of fixed plate 3, and bar groove 19's bottom surface is close to its inner wall and offers the draw-in groove 20 that the width is less than bar groove 19, and the length of draw-in groove 20 is the same with bar groove 19's length, and the width is less than bar groove 19's width. The opposite side of protection pad 18 is fixed with flexible connecting rod 21, and the other end of connecting rod 21 is fixed with the fixture block 22 that is located draw-in groove 20, and fixture block 22 can remove in draw-in groove 20, and connecting rod 21 is established by two sleeve covers and is constituteed, and the minor diameter sleeve is fixed on fixture block 22, and the major diameter sleeve is fixed on protection pad 18. A plurality of second grooves 23 are formed in the bottom surface of the strip-shaped groove 19, the second grooves 23 can exist independently or can be a whole, a stop block 25 is connected to the inside of each second groove 23 through a second elastic piece 24, each stop block 25 is in a triangular prism shape, and the setting directions are consistent. When the second grooves are independently arranged, the distance between two adjacent second grooves 23 is greater than or equal to the maximum diameter (the outer diameter of the large-diameter sleeve) of the connecting rod 21, and the distance between the stop 25 and the top surface of the strip-shaped groove 19 is less than the maximum diameter of the connecting rod 21 and greater than the minimum diameter of the connecting rod 21. When the second grooves are integrally provided, the interval between the adjacent stoppers 25 is equal to or greater than the maximum diameter of the connecting rod 21.

For the limitation of the diameter of the connecting rod and the spacing between the stops, it should be noted that: when the connecting rod 21 is retracted, as shown in fig. 4, the sleeve with a large diameter is clamped between two adjacent stoppers 25, and when the connecting rod is moved, the connecting rod 21 can only compress the connecting rod into the second groove 23 through the inclined surface of the stopper 25, so that the movement of the connecting rod and the protection pad is realized, and at this time, the connecting rod 21 cannot move in the opposite direction, which is the process of reducing the distance between the two protection pads 18. When the distance between the two protection pads 18 needs to be enlarged, because the straight surface of the stop block 25 limits the movement of the connecting rod 21, the connecting rod 21 needs to be pulled out of the fixing plate 3, as shown in fig. 7, the small-diameter sleeve of the connecting rod 21 is located between the two adjacent stop blocks 25, at this time, the clamping block 22 only needs to be lifted by a part of the distance from the clamping groove 20, the small-diameter sleeve is located in the area between the stop blocks 25 and the top of the strip-shaped groove 19, and therefore the protection pads are moved in the opposite direction, and further the distance between the two protection pads is enlarged. Of course, the movement in the opposite direction can also be realized by moving the elastic pad in the direction of the elastic pad, i.e. reducing the distance between the two protective pads, the specific operation being chosen by the individual.

Further, referring to fig. 10, in order to condition the shoulders, the fixing plate 3 is configured to have a cross-section of "Contraband", that is, the top surface and the bottom surface of the fixing plate 3 are respectively provided with the clamping plates 26 parallel to each other, the middle position of the horizontal portion of the fixing plate 3 is respectively provided with the strip-shaped notch 27, that is, the center of the clamping plate 26 is provided with the strip-shaped notch 27, the inserting mechanism is respectively arranged on the end surface of the horizontal portion (or the clamping plate 26) of the fixing plate 3 in the same direction as the opening direction of the strip-shaped notch 27, and the strip-shaped notch 27 is internally provided with the cushion 28. In use, the arms are opened and passed through the area between the two clamping plates 26, and the fixing plate is fixed to the back plate, which is also provided with fixing holes corresponding to the insertion mechanisms. For the insertion mechanism disposed on the clamping plate, the first through hole is also disposed through the clamping plate, and the structure of the insertion mechanism is the same as that disclosed above, and is not described herein again.
