AI Technical Summary

Technical Problem

Traditional sheet metal shears are prone to causing edge deformation and curling during the cutting process, and they do not conform to the way the human body exerts force, resulting in unsmooth use and easy blade deviation.

Method used

The design incorporates a rotating connection between the upper and lower blades. The lower blade has grooves to avoid cutting the material. A lever bolt and nut adjust the preload. A combination of a slider and a groove enables near-linear translational motion. A sleeve handle enhances comfort and safety. A spring automatically opens the blade, a retaining ring locks the blade, and a broken wire hole handles the wire.

Benefits of technology

It solves the problems of edge deformation and curling of sheet metal, optimizes the cutting effect, conforms to the human body's force exertion method, extends the tool life, and improves the tool's practicality and safety.

Abstract

The utility model discloses a novel metal sheet shears relates to sheet material processing field, including upper blade and lower blade, the end of upper blade and the end of lower blade rotation connection, upper blade and lower blade mutually cooperate the lower blade and be equipped with groove on, and the groove and upper blade do not interfere with each other, the cutting place of groove and upper blade and lower blade is collinear. The utility model discloses the groove design on lower blade, avoided the sheet material of traditional scissors in having completed cutting to hinder upper blade to continue to advance or to rub and collide with it, solved the deformation curling problem after sheet metal cutting, the utility model discloses the sliding block and the sliding slot combination cooperation lower handle along the lever shaft rotation, make the user's grip action can more directly, more efficient conversion into the shearing force of blade, avoided the wrist in traditional design to need to do the contortionist twisting action to adapt to the changing lever angle, and the power is more natural, more labor saving, and not easy to fatigue.
