Further, the front surface both sides of base plate 110 have all been seted up spout 113, and the rear surface both ends of slider 1311 all are equipped with trapezoidal piece 1313, and trapezoidal piece 1313 is located the inside of spout 113, and with spout 113 sliding connection, through the slip between trapezoidal piece 1313 and the spout 113, is convenient for further promote the stability that module body 131 goes up and down.

Specifically, a sliding plate 1123 is disposed between the side plate 112 and the bottom plate 1122, a sliding plate protruding block 1124 is disposed on the front surface of the sliding plate 1123, an auxiliary block groove 1316 is disposed on the rear side surface of the auxiliary block 1314, the auxiliary block groove 1316 is located on the surface of the sliding plate protruding block 1124 and slides on the surface of the sliding plate protruding block 1124, so as to further improve the lifting stability of the module body 131.

In addition, motor 210 is installed to base 200 rear side surface, motor 210 is through the output shaft fixedly connected with motor bevel gear 211 that the front end was equipped with, dwang 1111 bottom is equipped with down bevel gear 1114, lower bevel gear 1114 meshes with motor bevel gear 211, through motor 210 work, drive motor bevel gear 211 work, motor bevel gear 211 drives down bevel gear 1114, thereby it rotates to drive dwang 1111, drive equipment operation through power device, further use manpower sparingly, improve work efficiency simultaneously.

In addition, the rear side surface of the base 200 is provided with a mounting plate 220, the motor 210 is positioned above the mounting plate 220, the front end of the mounting plate 220 is provided with a connecting plate 221, the front end of the motor 210 is provided with a connecting plate 212, and the connecting plate 212 is fixedly connected with the connecting plate 221 through bolts, so that the motor 210 is conveniently mounted and fixed.

Further, gear groove 2000 has been seted up to base 200 inside, last commentaries on classics hole 2001 has been seted up on gear groove 2000 top, side commentaries on classics hole 2002 has been seted up to gear groove 2000 rear end, dwang 1111 runs through base 200 and goes up commentaries on classics hole 2001 and rotate and be connected, and bevel gear 1114 is located inside gear groove 2000 down, the output shaft of motor 210 runs through connecting plate 221 and rotates with side commentaries on classics hole 2002 and be connected, and bevel gear 211 is located inside gear groove 2000, through the gear groove 2000 that sets up, be convenient for protect bevel gear 1114 and bevel gear 211 down.
