[0031] Working principle:

[0032] First, the operator places the orthodontic bracket inside the clamp 16. Based on the size of the bracket, the operator turns the adjusting screw 17 on the outside of the rotating arm 15. The clamping force is transmitted to the surface of the bracket through the clamping head, firmly fixing the bracket to the worktable of the cutting machine. After the cutting process is completed, the power source reverses its action, releasing the clamping head and removing the bracket. Then, the clamp 16 is clamped to the bracket. Next, cylinder 2 begins operation, with its bottom sliding towards the inside of the cutting machine body 1. During this sliding process, the hydraulic rod 3 slides downwards simultaneously, moving the frame 4 towards the cutting machine body 1. The frame 4 slides down from its inner bottom end. As the frame 4 slides down, the groove at the bottom end of the frame 4 passes through the outside of the sliding block 7. When the top of the groove of the frame 4 abuts against the sliding block 7, the sliding block 7 pushes the sliding rod 8 on the outside of the fixing plate 6 to slide to the left. During the sliding process, the spring 9 is squeezed, and the frame 4 pushes the sliding block 7 to slide to the left in the groove at the top of the base 18. During the sliding process, the telescopic rod 13 is pushed to slide towards the center of the bottom end of the cutting head 5. During the sliding process, the cutting head 5 cuts the orthodontic brackets inside the two sets of clamps 16. After the cutting is completed, the cut orthodontic brackets are removed.
