Problems solved by technology

[0002] The scissors are mainly composed of two scissor bodies, which are hinged together by a connecting shaft. When cutting something, the lever principle is used, and the hinge shaft is the fulcrum. The current scissor hinge shaft is fixed on the scissor body. During use, if the edge of the scissors has a gap or curls, the scissors can only be scrapped and cannot be used, resulting in waste

Abstract

The invention discloses a coupling screw for shear bodies. The coupling screw comprises a main screw and an auxiliary screw connected in the main screw; the main screw consists of a head and a connecting part; the connecting part of the main screw is in a cylinder shape, inner threads are arranged on the inner wall of the cylinder, and two straight face ends are symmetrically arranged on the outer wall of the cylinder; an embossment is arranged on the end face of the connecting part; the auxiliary screw consists of a head and a connecting part; the connecting part of the auxiliary part is of a column shape, and outer threads matching with the inner threads of the main screw are arranged on the upper end of the column; a groove matching with the embossment is arranged on the end face of the head of the auxiliary screw; and the outer walls of the heads of the main screw and the auxiliary screw are respectively of an arc shape. According to the scheme disclosed by the invention, the coupling screw for the shear bodies adopts a structural design of combining the main screw and the auxiliary screw, so as to realize the mutual connection between the shear bodies and achieve the using function of a pair of shears; and the coupling screw has a simple structure and is very convenient to use.

Description

technical field [0001] The invention relates to a screw, in particular to a connecting screw for a scissor body. Background technique [0002] The scissors are mainly composed of two scissor bodies, which are hinged together by a connecting shaft. When cutting something, the lever principle is used, and the hinge shaft is the fulcrum. The current scissor hinge shaft is fixed on the scissor body. During use, if the edge of the scissors has a gap or curls, the scissors can only be scrapped and cannot be used, resulting in waste. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a connecting screw that is movably connected to the scissors body. [0004] The technical solution of the present invention is achieved as follows: a connecting screw for scissors body, including a female nail and a sub-nail connected in the female nail, the female nail is composed of a head and a connecting part; t...
