During the cutting process, the negative pressure collection component collects the debris generated by the cutting to prevent the debris from splashing; by setting the matching structure of the rotating shaft, sleeve A, sleeve B and drive component D, the aluminum profile to be processed is placed on the sleeve B. When the sleeve B is pushed, the distance between the sleeve B and the sleeve A shrinks to pre-clamp the workpiece, and then the push continues. Due to the tension of the tension spring, the clamping force becomes larger and larger, so that the aluminum profile is further clamped, thereby preventing it from shaking during the cutting process. Further pushing the sleeve B can make the aluminum profile move toward the cutting disc while maintaining the clamping state until it is cut off. The angle of the cutting disc is adjustable so that the end of the aluminum profile can be cut into a bevel of the required angle. BRIEF DESCRIPTION OF THE DRAWINGS
