Clamping mechanism and full-automatic numerical control sectional material cutting equipment

The utility model relates to the technical field of material processing, in particular to a clamping mechanism and profile full-automatic numerical control cutting equipment, which comprises a clamp support, clamp limiting sliding tables are symmetrically and fixedly connected to the lower end face of the inner side of the clamp support, and clamping blocks are inserted into the outer sides of the clamp limiting sliding tables; the lower end face of the clamp support is fixedly connected with a motor groove, the inner end of the motor groove is fixedly sleeved with a gear motor, and the output end of the gear motor is fixedly connected with an anti-loosening fastening device. The clamping mechanism and the full-automatic numerical control sectional material cutting equipment have the beneficial effects that the anti-loosening fastening device is arranged, and the gear cannot rotate under the limitation of the transmission screw rod, so that the phenomenon that a clamp is loosened due to vibration during cutti
