[0002] Corner brackets are right-angled hardware widely used in doors, windows and curtain wall projects, mainly used to fix two adjacent right-angled connecting edges in doors, windows and decorative surface materials. Corner brackets are usually cut from long strips of corner bracket profiles. In existing cutting devices, such as the corner bracket cutting machine for door and window profiles disclosed in patent CN218694296U, the corner bracket profiles are conveyed by conveyor rollers during operation. When the corner bracket profiles are conveyed to the bottom of the cutter, the second motor drives the bidirectional screw to rotate, thereby driving the clamps on both sides to clamp and fix the corner bracket profiles, and then the cylinder drives the cutter to cut the corner bracket profiles.

[0003] However, the above device has certain problems: when positioning the diagonal code profile through the bidirectional screw, on the one hand, the operating efficiency of the bidirectional screw is low, and the speed of the linear motion of the splint driven by the rotation of the screw is slow, and it cannot be positioned quickly; on the other hand, the bidirectional screw and the ring will be subjected to force during the cutting process, which will damage the transmission accuracy of the bidirectional screw in the long run, thereby affecting the positioning accuracy.
