[0002] Laser cutting uses laser beams to replace traditional mechanical knives, and has the characteristics of high precision, fast cutting, smooth incision, and low processing cost. During laser cutting, the plate to be cut needs to be placed on the cutting table. When the mass of the plate to be cut is large, it is not necessary to fix the plate to be cut; when the mass of the plate to be cut is small, it is necessary to fix the plate to be cut to avoid the plate to be cut from moving during the cutting process due to the cut-off part. When cutting the raw material of the metal pipe clamp, the raw material plate is small in mass, so it needs to be fixed during cutting. When actually cutting panels with smaller mass, the existing laser cutting equipment is not equipped with a professional clamping structure; therefore, the staff is required to set up an additional fixed structure to fix the panels to be cut on the cutting table; and then perform the laser cutting operation; the entire cutting process requires the external fixed structure to fix the panels to be cut on the cutting table; it is relatively inconvenient, and the cutting efficiency needs to be further improved.
