The operating member abuts against the operating end. There is a baffle in the supporting member. On the side of the locking end away from the gear part, there is a third elastic member, and the third elastic member abuts against the baffle. In the non-loaded state, the locking end meshes and locks with the gear part; the locking assembly can lock the gear part during film application or when not film-applying, so that it cannot rotate randomly.

[0023] 9. On one side of the gear part of the film application box of the present utility model close to the supporting surface, there is a cylindrical hole. Inside the cylindrical hole, a fourth elastic member and a ball are arranged in sequence from the bottom wall upwards; on the side of the supporting surface close to the gear part, there are a number of circular grooves corresponding to the balls.
