The first lifting device 9 is started, and the mounting frame 4 moves downward, so that the pressure rollers 5 on both sides below are in contact with the outer wall of the composite pipe to be cut, which has a positioning effect on the composite pipe to be cut. When the cutting operation is performed, it is ensured that the composite pipe will not be tilted, and the fixing is convenient, and the composite pipe of the fixed body model can be clamped and fixed without adjusting the fixing device.

When the support rollers 6 rotate, the composite pipe to be cut is synchronously driven to rotate between the two support rollers 6.
