[0002] The H-beam is an economic section high-efficiency profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio, named after its cross-section being the same as the English letter "H". Since all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance in all directions, simple construction, cost savings, and light structural weight, and has been widely used. The laser cutting and welding machine is also often called a numerically controlled laser cutting and welding integrated machine, which mainly uses computer programming to complete automatic or semi-automatic cutting and welding, and complete the cutting and welding of complex planar straight lines, arcs, and arbitrary trajectories.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] In the present invention, the H-shaped steel is placed on the conveying rack. The elastic member is used to push the sliding plate to move, so that the lifting mechanism drives the clamping mechanism to move, enabling the clamping mechanism to abut against the H-shaped steel.
