Countersunk head structure for both clamping piece and cutter body

The invention relates to the technical field of cutters, and discloses a countersunk head structure for both a clamping piece and a cutter body. The countersunk head structure for both the clamping piece and the cutter body comprises a cutter handle, wherein a connecting assembly is arranged in the cutter handle, a blade is arranged on the outer wall of the connecting assembly, a limiting assembly is arranged in the cutter handle, the connecting assembly comprises a positioning sleeve arranged in the cutter handle, a connecting screw is arranged in the positioning sleeve, the blade is arranged on the outer wall of the connecting screw, and a first gasket is arranged on the front face of the blade. According to the countersunk head structure for both the clamping piece and the cutter body, the cutter handle and the blade are guided through a first bearing and a second bearing on the connecting assembly, thus the abrasion strength of the cutter handle and the blade in folding processes is reduced, and then a sp
