[0044] The working principle is as follows: in the initial state, the rubber ring mechanism 500 and the product mechanism 400 are located close to the center of the wheel disc mechanism 300, when working, the driving mechanism 200 drives the wheel disc mechanism 300 to rotate, and then drives the rubber ring mechanism 500 and the product mechanism 400 to move away from the center of the wheel disc mechanism 300 to a certain position, so that the rubber ring mechanism 500 can open the rubber ring, and the product mechanism 400 can accommodate the product, then the product is put in, and then the driving mechanism 200 drives the rotating disc mechanism to reverse, so that the rubber ring mechanism 500 and the product mechanism 400 move towards the wheel disc mechanism 300, and then the rubber ring is sleeved on the product.

[0045] It should be noted that the preset direction should be determined according to the specific setting structure of the wheel disc mechanism 300, as long as the rubber ring mechanism 500 and the product mechanism 400 can move towards or away from the center of the wheel disc mechanism 300.
