The operation panel is in signal communication with the second electric telescopic cylinder.

[0007] Furthermore, it also includes a first electric telescopic cylinder, a first mounting rod, a first motor, a first rotating wheel, and a first transmission assembly. Several first electric telescopic cylinders are symmetrically arranged through the side of the mounting frame. A first mounting rod is installed at the telescopic end of each first electric telescopic cylinder. A first motor is installed on the side of each first mounting rod.

[0009] Furthermore, it also includes guide rods and lifting plates. Guide rods are symmetrically installed on the side of the support frame, and the guide rods are slidably connected to the lifting plates.

[0010] Furthermore, it also includes a cylinder, with the cylinder installed inside the support frame, and the piston of the cylinder connected to the lifting plate.

[0011] Furthermore, the middle part of the lifting plate is an upward-facing arc shape, and the end of the arc shape is movable to contact the feed port of the mounting frame.

[0022] The pipe to be cut is placed in the mounting frame 2. The second electric telescopic cylinder 8 works, pushing the second mounting rod 9 to move towards the pipe. The second rotating wheel 11 approaches the pipe and clamps it. The laser cutting machine works to cut the pipe. At the same time, the second motor 10 works, driving the second transmission component 12 to work. The second transmission component 12 drives the second rotating wheel 11, which pushes the pipe to move, achieving the effect of rotating the pipe for cutting.
