Multiple circular holes are opened on both side end faces of the second circular ring.

[0008] Through the above technical scheme, by pulling the lower L-shaped plate downward, the two second semicircular plates on the lower side are moved in opposite directions. When multiple cylinders leave the arc groove, the plastic body is placed on the inner wall surface of the lower first semicircular plate, and then the lower L-shaped plate is pulled downward, and the two second semicircular plates on the lower side are moved closer to the middle. When the two are in contact with the first semicircular plate, the pulling on the lifting plate is released, and then the cylinders in the multiple upper first semicircular plates are subjected to the same operation. At this time, the upper first semicircular plate is covered on the upper side of the outer end surface of the plastic body. In the process of placing the first semicircular plate, the first fixed plate pushes the slider. When the two first semicircular plates are in contact, the slider is pushed into the inner wall of the first fixed plate under the action of the first return spring, thereby connecting the two first semicircular plates together, and finally the two second semicircular plates on the upper side are moved to their original positions.

[0009] Furthermore, the two arc-shaped grooves are respectively provided on the inner walls of the two first semicircular plates on opposite sides, the plastic body is clamped and arranged between the two arc-shaped grooves, and the second circular ring is fixedly sleeved in the middle position of the outer end surface of the first circular ring;

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model provides a fastening plastic part, which moves the lower L-shaped plate downward while holding the two second semicircular plates at the lower side and moving them in opposite directions. When the multiple cylinders leave the arc groove at the lower side, the pulling of the L-shaped plate is released, and the plastic body is placed on the inner wall surface of the lower first semicircular plate. Then, the lower L-shaped plate is moved downward while holding the two second semicircular plates at the lower side and moving them closer to the middle, so that the second ring is fixed in the arc groove. By arranging the second semicircular plates and the cylinders, when the plastic body is connected to the fastener, it is not necessary to apply adhesive on the surface of the plastic body, which is more convenient.

[0023] 2. The utility model provides a fastening plastic part, which moves the upper L-shaped plate upward while holding the two second semicircular plates on the upper side and moving them in the opposite direction. When the multiple cylinders leave the arc-shaped groove on the upper side, the pulling of the L-shaped plate is released, and the first semicircular plate on the upper side is placed on the surface of the plastic body. During the placement process, the protrusion under the first fixing plate abuts against the slider, thereby driving the slider to move to one side. When the two first semicircular plates are fitted together, the slider is pushed into the inner wall of the protrusion by the rebound force of the first return spring, thereby fixing the two first semicircular plates together. By providing the first fixing plate and the second fixing plate, it is not necessary to tighten the bolts when the two first semicircular plates are fixed together, which is more convenient.
