[0002] Plastic buckets are mostly made of polyethylene, polypropylene, polyester and other plastics through blow molding, injection molding, vacuum forming and rotation molding. They are not only shatterproof, rust-free and lightweight.

[0003] Chinese patent CN213382565U discloses a trimming device for plastic bucket production, including a brake motor. Since the output shaft of the brake motor is connected to a gear, the brake motor drives the gear to rotate. The gear has racks meshing on both sides, so the rotation of the gear causes the two racks to move outward. Since a connecting rod is fixedly connected to one end of each rack, and a fixing component is fixedly connected to the center of the connecting rod, the rack drives the fixing component on the connecting rod to fix the plastic bucket.

[0004] However, the aforementioned trimming device for plastic bucket production fixes the plastic bucket by pressing the inner wall of the open end of the plastic bucket with two fixing parts, which can easily deform the open end of the plastic bucket and affect the trimming effect.

[0005] In view of this, this utility model is proposed. Utility Model Content
