[0027] Through the above technical solution, the controller 201 can be fixed to the housing 1 through the connecting plate 3. At the same time, the controller 201 refers to a main command device that controls the starting, speed regulation, braking and reversal of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit in a predetermined order.

[0028] Specifically, the back side of the rotating motor 203 is fixedly connected to a support base 6 , and the back side of the support base 6 is fixedly connected to the inner wall of the housing 1 .

[0029] Through the above technical solution, the rotating motor 203 can be fixed in the housing 1 through the support seat 6, so that the rotating motor 203 can be used stably.

[0030] Specifically, a power-assisting plate 7 is fixedly connected to the inner wall of the housing 1 , and a bottom surface of the power-assisting plate 7 is fixedly connected to the top end of the electric push rod 205 .

[0032] Specifically, the telescopic end of the electric push rod 205 is fixedly connected to the connecting frame 8 , and the bottom surface of the connecting frame 8 is fixedly connected to the upper surface of the sliding block 206 .

[0033] Through the above technical solution, the electric push rod 205 and the sliding block 206 can be connected by using the connecting frame 8, so that the electric push rod 205 can push the sliding block 206 to move.
