The transmission screw 11 passes through the outer wall of one end of the special reduction box 1 and is sleeved with a dust cover 12, and the end of the dust cover 12 away from the transmission screw 11 is sleeved on the sleeve of the special reduction box 1.

[0023] Specifically, flange mechanisms are provided at the ends of the special reduction box 1 and the motor 2 that are close to each other. The special reduction box 1 and the motor 2 are fixedly connected through the flange mechanisms respectively. The output end of the motor 2 is inserted into the interior of the special reduction box 1 and connected to the coupling sleeve 5.

[0024] Specifically, the sliders 10 are slidably connected inside the slide grooves 9 , and the transmission screw 11 passes through one end of the trapezoidal nut 6 and is inserted into the dustproof sleeve 7 and fixed to the end close to the inner block 8 .
