[0007] Furthermore, it also includes a motor bracket, a servo motor, a screw and a push plate. The servo motor is connected to the side of the fixed bracket through the motor bracket. The output shaft of the servo motor is connected to the screw through a coupling. The push plate is connected to the placement frame in an opposite sliding manner. The push plate is L-shaped and is connected to the screw through threads.

[0008] Furthermore, the screw rod is provided with symmetrical threads.

[0009] Furthermore, it also includes a fixed sleeve, a pull rod, a spring, a rotating rod and a clamping plate.
