Two bases 6 are provided under the bottom plate 1. A stopper is provided at one end of the bidirectional screw rod 404. By providing the stopper, the stopper can block the moving plate 405 to prevent the moving plate 405 from being separated from the bidirectional screw rod 404 when moving.
[0024] Two support plates 2 are connected to the bottom plate 1. Two slide grooves 3 are provided on the sides of the two support plates 2. A moving mechanism 4 is slidably connected in the slide grooves 3. The moving mechanism 4 includes four sliders 401. The sliders 401 are slidably connected in the corresponding slide grooves 3. By setting the slide grooves 3 and cooperating with the slide grooves 3 and the sliders 401, it is possible to avoid the sliders 401 from being offset and stuck during movement, thereby ensuring the stable movement of the sliders 401.
[0025] The sides of the two corresponding sliders 401 are connected with a fixed box 402, and four limit slots 7 are provided on the fixed box 402. By providing the limit slots 7, the limit slots 7 cooperate with the limit block 408 to avoid the limit block 408 from being offset and stuck during movement, thereby ensuring the stable movement of the limit block 408.
[0026] The limit block 408 is slidably connected in the limit slot 7, the fixed box 402 is connected with a motor 403, one end of the motor 403 is connected with a bidirectional screw rod 404, the bidirectional screw rod 404 is externally threadedly connected with two moving plates 405, and the moving plate 405 is provided with an inclined groove 406. By setting the inclined groove 406, the inclined groove 406 and the connection column 407 cooperate with each other, so as to avoid the connection column 407 from being offset and stuck when moving, thereby ensuring the stable movement of the connection column 407;

When the motor 403 drives the bidirectional screw rod 404 to rotate, the two movable plates 405 move toward each other, and drive the two connecting columns 407 to slide in the inclined groove 406, so that the four limit blocks 408 move toward each other in the four limit grooves 7, and the fixed box 402 drives the piston plate 501 to slide downward in the piston cylinder 502 under the action of its own gravity, and squeezes the spring 503, and drives the slider 401 to move downward in the slide groove 3.
