A clamping mechanism is arranged on the top of the base through a transmission mechanism. The transmission mechanism includes a rotating rod, a transmission screw rod, and a pulley mechanism. The rotating rods are symmetrically and rotatably arranged inside both ends of the base, and gears are fixedly installed on the rotating rods. Through the transmission mechanism, a rack, an adjusting plate, a spring, and a clamping plate, the two ends of the metal plate can be clamped and fixed. The chips generated by cutting will fall inside the inner groove and the cutting groove, and the baffle can also block the cutting position to prevent the chips from splashing to both sides and will not affect the fixation of the metal plate; Prior Art 2 (a Chinese patent with application number CN202321702039.9 and published on December 22, 2023) is a metal part positioning cutting device with a waste recycling function, which relates to the technical field of metal part positioning cutting. It includes a cutting table and a robotic arm slidably arranged above the cutting table. A cutting head is arranged at the bottom of the robotic arm, and a moving shock absorption mechanism is arranged at the upper end of the cutting head. Multiple spaced first placing rods are fixedly arranged at the upper end inside the cutting table, and multiple spaced second placing rods are fixedly arranged at both sides of the multiple first placing rods inside the upper end of the cutting table.
