Countersunk head structure with non-molten clamping piece and knife body

Abstract

The invention relates to a countersunk head structure with an non-molten clamping piece nor knife body. The countersunk head structure comprises a tool body structure, an auxiliary structure and a fixing rod, the tool body structure is located on the outer side of the fixing rod, the auxiliary structure is located on the right side of the tool body structure, the tool body structure comprises a connecting plate, and the front face of the connecting plate is fixedly connected with a first fixing block; and the front face of the connecting plate is fixedly connected with a second fixing block, a fixing check block is fixedly connected between the first fixing block and the second fixing block, the auxiliary structure comprises pressing springs located in the second fixing block, connecting blocks are fixedly installed on the opposite sides of the two pressing springs, and the left sides of the connecting blocks are fixedly connected with sliding blocks. According to the countersunk head structure with the non-molten clamping piece nor knife body, the first fixing block and the second fixing block effectively protect a whole structure, a knife edge is pulled out to be lengthened, the knife edge is connected with a knife handle through the fixing rod, and it is guaranteed that the whole structure is reliably connected.

Description

technical field [0001] The invention relates to the technical field of cutting tools. Background technique [0002] A knife is a short weapon with a long blade on one side.
