Blade clamp

The utility model provides a blade clamp. The blade clamp comprises a mounting seat and a clamping tray which is arranged on the mounting seat and used for clamping a blade. A plurality of first mounting grooves used for clamping blades are formed in the clamping material disc, and locking pieces used for locking the fixed blades are detachably arranged on the first mounting grooves. A receding groove is further formed in the clamping tray, and at least part of the first mounting groove is overlapped with the receding groove. The multiple first mounting grooves are located in one side of the receding groove, and the depth of the receding groove is larger than that of the first mounting grooves. By means of the first mounting grooves, a plurality of blades can be assembled on one blade clamp in batches, and the blades can be machined in batches in cooperation with a numerical control laser cutting machine, so that the number of times of disassembling and assembling the blade clamp can be effectively reduced, a
