Further, protection machanism 600 includes pull ring 610 and limiting plate 614, one side fixedly connected with limiting plate 614 of protection casing 113, and the quantity of limiting plate 614 is two sets of, one side fixedly connected with second fixed plate 611 of two sets of limiting plates 614, the inside of second fixed plate 611 transversely alternates has inserted bar 613, one side fixedly connected with pull ring 610 of inserted bar 613, stopper 615 has been cup jointed on the surface of inserted bar 613, when the device uses, staff's accessible rotating connection board 114 covers protection casing 113 on control panel 115 surface, simultaneously accessible inserted bar 613 transversely inserts protection casing 113 and control panel 115 and is fixed in control panel 115 surface with protection casing 113, collide with and the mistake is operated when preventing the device from using, the life of device has been promoted greatly.

Furthermore, a fourth spring 612 is sleeved on the surface of the inserted rod 613, one side of the fourth spring 612 is fixedly connected to the second fixing plate 611, when the protection cover 113 covers the surface of the control panel 115, a worker loosens the pull ring 610, and the inserted rod 613 can be transversely inserted into the control panel 115 through the elastic potential energy of the fourth spring 612, so that the use convenience of the device is greatly improved.

The working principle is as follows: when the device is used, a worker can drive the transmission belt 219 to rotate by starting the motor 218, the transmission belt 219 can drive the second bevel gear 222 to rotate by the first rotating rod 220 when rotating, the reciprocating screw 215 can be rotated at the moment, the rack 223 and the rotating gear 213 can be moved when the reciprocating screw 215 rotates, the effect of adjusting the detection angle of the air inlet 118 is achieved, and meanwhile, the first threaded sleeve 217 reciprocates on the surface of the reciprocating screw 215, so that the air inlet 118 can be uniformly and evenly detected.

When the device removes, staff's accessible clockwise rotation second bull stick 414 drives the lead screw 413 rotatory, when lead screw 413 is rotatory, the second thread bush 412 of lead screw 413 surface threaded connection removes to the direction that is close to each other, can straighten second connecting rod 417 this moment and can make universal wheel 416 and ground laminating, can remove the device this moment, when the device detects, staff's anticlockwise rotation second bull stick 414 can make two sets of second connecting rods 417 shrink, device base 119 and ground laminating this moment.

When the device is used, a worker can cover the protection cover 113 on the surface of the control panel 115 through the rotating connecting plate 114, meanwhile, the protection cover 113 and the control panel 115 can be transversely inserted into the protection cover 113 through the inserting rod 613 to fix the protection cover 113 on the surface of the control panel 115, the device is prevented from being collided and mistakenly operated when in use, when the protection cover 113 is covered on the surface of the control panel 115, the worker loosens the pull ring 610, and the inserting rod 613 can be transversely inserted into the control panel 115 through the elastic potential energy of the fourth spring 612.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
