Curved-blade scissors and thread cutters for circular knitted sock cuffs.

Abstract

The invention relates to a curved-blade scissor and a sewing thread cutting device for the sock cuff of circular knitted fabric, relating to the engineering field of scissors, and solving the engineering problem of the cutting mode where two scissor blades moving towards each other to close easily interfere with other external structures and are inconvenient to operate. The curved-blade scissor consists of a base, a forward-reverse slider, and a curved-blade cutting blade. The forward-reverse slider slides to the base, one end of the slider is the drive end, and the straight cutting blade is fixed to the other end of the slider. The curved-blade cutting blade is rotatable to the slider via a shaft assembly. When a drive mechanism or manual force is applied to the drive end, the slider moves linearly relative to the base. The curved-blade cutting blade can rotate around the shaft assembly under the pulling force of the slider to close with the straight cutting blade to cut the target material. The curved-blade scissor has a structure capable of strong cutting.With the linear movement of the straight cutting blade and the rotational movement of the curved cutting blade, interference with the external structure can be reduced, and operation is simple and convenient.
