[0014] (III) Beneficial Effects

[0015] 1. This utility model, through the arrangement of a cylinder, connecting shell, cutting head, first rack, gear, second rack, and protective cover, allows the cutting head to move downwards via the connecting shell when the moving end of the cylinder drives it. Simultaneously, the first rack connected to the connecting shell moves downwards, causing the gear meshing with the first rack to rotate counter-clockwise. This counter-clockwise rotation of the gear causes the second rack meshing with the gear to move the protective cover upwards. When the protective cover reaches a certain height, it surrounds the orthodontic appliance to be cut. Simultaneously, the downward-moving cutting head is positioned appropriately to cut the orthodontic appliance. Furthermore, when cutting the orthodontic appliance, the flying debris or sparks are blocked by the protective cover, greatly reducing the probability of injury to the operator.

[0016] 2. This utility model, through the setting of the rotating rod, enables the cutting head to rotate. Thus, when the rotating rod is rotated, the cutting head can rotate accordingly through the rotational cooperation between the cutting head and the connecting shell. When the cutting head rotates back and forth, the cutting of the orthodontic appliance can be completed. Attached Figure Description
