When the inner sides of the two clamping plates 15 are in contact with the pipe, the pressure sensor 16 reaches the set clamping pressure, and transmits a signal to the external control switch to start the extension of the electric telescopic rod 12. The extension of the electric telescopic rod 12 makes the two racks 10 move to the outside of the operating table 1 at the same time and separate from the gear 9. The two sliders 33 are no longer moving, so that the moving plate 6 is then moved to feed the pipe. The laser cutting machine for cutting multiple pipes can automatically clamp the pipe while automatically loading, and the clamping assembly can clamp pipes of different specifications. When laser cutting is performed, turn on the external control switch. Start the electric telescopic rod 19, the electric telescopic rod 19 extends, driving the laser cutting head 20 to move downward, so that it is located on the upper surface of the pipe for subsequent cutting.
