Abstract

A trace-free double-sided rapid cut toothed shears having high and low teeth, comprising: a movable blade (1) and a stationary blade (2), the movable blade and the stationary blade being hinged by means of a pivot (3), and finger rings (4) being provided at tail ends of both the movable blade and the stationary blade; a blade edge of the stationary blade is composed of a plurality of tooth edges of stationary blade teeth (21) that are arranged apart and side by side, a tooth edge of each stationary blade tooth being formed by a horizontal plane (5) and an inclined plane (6) intersecting with each other, and the cutting edge angle of the tooth edge of each stationary blade tooth being 15°-45°; a guiding convex angle (22) is arranged at the edge of the tooth edge of each stationary blade tooth that is near a pivot side respectively; a guiding inclined plane (23) is provided on a surface at which a guiding convex angle is in contact with a blade edge of the movable blade, and the blade edge of the movable blade is guided by the guiding inclined plane so as to close with a tooth edge of a stationary blade tooth, at which the guiding inclined plane is located, so as to cut. The toothed shears do not easily pull hair when cutting hair, and there is little friction during hair cutting such that cutting hair is pleasant, and the toothed shears may sharply cut the hair such that the cross section of the hair is flat.

Abstract

Thinning shears with teeth each having a wavy tip. The shears comprise a movable blade (1) and stationary blade (2); the movable blade (1) and the stationary blade (2) are hinged by means of a pivot (3); finger rings (4) used for the fingers to drive the blades to be opened and closed are respectively provided at tail ends of both the movable blade and the stationary blade; the hair is cut off by moving the blade edge of the movable blade to be opened and closed relative to the blade edge of the stationary blade; the blade edge of the stationary blade consists of multiple stationary blade comb teeth (21) arranged side by side at intervals; a guide protruding corner (22) is provided at the edge of the tip of each of the stationary blade comb teeth close to the pivot side; a guide bevel (23) is provided on the surface of each of the guide protruding corners in contact with the blade edge of the movable blade; the blade edge of the moving blade is guided by the guide bevels and then closed relative to the tips of the stationary blade comb teeth where the guide bevels are located. According to the thinning shears with teeth each having a wavy tip, the hair is not easy to be caught and less haircutting friction is produced during haircutting; thus, the head of a customer will not feel painful, and a better feel can be provided to the hand of a haircutter during haircutting.
