[0022] like Figure 2 As shown, the transmission assembly 4 includes a sprocket transmission assembly 41 and a pushing assembly 42 engaged with the positioning rod 5 .

[0023] like Figure 3 As shown, the sprocket transmission assembly 41 includes a sprocket transmission system 411 installed on the floor, and the sprocket transmission system 411 is connected to a servo motor.

[0024] like Figures 4 to 6 As shown, the pushing assembly 42 includes a moving platform 421 slidably mounted on the floor, and the moving platform 421 is slidably mounted with a hook 422 engaged with the positioning rod 5, and the moving platform 421 is provided with a spring 423 for driving the hook 422 to return to its original position, and a connecting portion 424 is provided under the moving platform 421, and the connecting portion 424 is connected to the sprocket transmission assembly 41 through screws.
