Problems solved by technology

[0002] Scissors are one of the common hardware tools. They can be used to cut cloth, paper and iron sheets. When using scissors for cutting, since the materials are mostly flexible and easy to bend, the cloth is bent during the cutting process, making it impossible for the cutter to follow the direction accurately. Cut the material in a straight line, which makes the material cut irregularly, resulting in a waste of raw materials; in addition, the material will hang down after cutting, exerting a lateral force on the cutting edge of the scissors, and it is easy to cause the cutting to be not straight, which not only wastes the material , which also brings inconvenience to the follow-up work

Abstract

The invention relates to a pair of auxiliary straight scissors. The auxiliary straight scissors comprise two scissor blades. Each scissor blade comprises a front end and a handle end. The scissor blades are symmetrically installed on a rotary shaft. Fastening rings are installed at the two ends of the rotary shaft. Calibrators are installed on the fastening rings in a sleeving mode. Each calibrator comprises two sets of clamping pieces, and the two sets of clamping pieces are connected through a telescopic rod. Each set of clamping piece comprises a supporting rod and a pressing rod, and the supporting rod and the pressing rod extend towards the front ends of the scissor blades in parallel. Idler wheels are installed on the side faces, opposite to the supporting rods, of the pressing rods, and the axes of the idler wheels are perpendicular to the scissor blades. All the idler wheels are made of elastic materials. Each calibrator further comprises a calibration plate. The calibration plates extent towards the handle ends of the scissor blades in the way of being parallel to the scissor blades. By the adoption of the scissors, accurate straight shearing can be achieved, the shearing efficiency is effectively improved, and meanwhile, the shearing precision is improved.

Description

technical field [0001] The invention relates to a hardware tool, especially a pair of scissors. Background technique [0002] Scissors are one of the common hardware tools. They can be used to cut cloth, paper and iron sheets. When using scissors for cutting, since the materials are mostly flexible and easy to bend, the cloth is bent during the cutting process, making it impossible for the cutter to follow along accurately. Cut the material in a straight line, which makes the material cut irregularly, resulting in a waste of raw materials; in addition, the material will hang down after cutting, exerting a lateral force on the cutting edge of the scissors, and it is easy to cause the cutting to be not straight, which not only wastes the material , but also bring inconvenience to the follow-up work. Contents of the invention [0003] In view of the above problems, the present invention provides an auxiliary linear scissors, which can realize more accurate linear cutting, ef...
