Hinged pin shaft with cutting edge gap of shear capable of being adjusted

Abstract

The invention discloses a hinged pin shaft with the cutting edge gap of a shear capable of being adjusted. The hinged pin shaft is mainly characterized in that a pin shaft body used for pin joint of a left cutter body and a right cutter body is arranged in a first through hole of the left cutter body and a second through hole of the right cutter body of the shear, and the left cutter body and the right cutter body are oppositely assembled; the external diameter of the pin shaft body is in movable fit with the first through hole and the second through hole; a threaded through hole is formed in the center line of the pin shaft body, and a regulating screw used for regulating the cutting edge gap of the shear is arranged in the threaded through hole; a circular groove is formed in the left end of the regulating screw, and a first round screw head which is of an integrated structure is arranged at the right end of the regulating screw; and the upper end of an integral structure hexagon pin head located at the left end of the pin shaft body is provided with a threaded hole which is perpendicular to the center line of the pin shaft body and communicates with the threaded through hole, and an anti-loose screw is arranged in the threaded hole. By means of the hinged pin shaft, the gap between a left cutting edge of the left cutter body and a right cutting edge of the right cutter body of the shear can be regulated easily, so that the left cutting edge and the right cutting edge of the shear make close contact with each other, convenience is provided for easily and smoothly cutting off objects like paper and cloth, and the service life of the shear can be prolonged.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a hinge pin that can adjust the gap between scissors blades. Background technique [0002] The left blade body and the right blade body of the existing scissors are riveted together with rivets. The rivet head will be worn out, resulting in a gap between the left blade body and the right blade body of the scissors, so that the left blade of the left blade body of the scissors and the right blade of the right blade body cannot be in close contact, and it is impossible to cut such as paper, cloth, plastic film, etc. objects, causing the scissors to be scrapped. Contents of the invention [0003] The purpose of the present invention is to improve the deficiencies of the prior art, to provide a hinge pin that can adjust the gap between the blades of scissors, which can easily adjust the gap between the left blade of the left blade of the scissors and the right blade of t...
