Cutter tooth with gradually-changed acute-angle cutting edge and trimming cutter

Abstract

The invention discloses a cutter tooth with a gradually-changed acute-angle cutting edge and a trimming cutter. The cutter tooth is characterized in that a slope extends from the front end of a cutter tooth body to the tail end of the cutter tooth body to form a cutting edge front end and a cutting edge tail end, the included angle S1 of the cutting edge front end is larger than the included angle S2 of the cutting edge tail end, and the cutting edge angle from the cutting edge front end to the cutting edge tail end is gradually reduced. The cutter tooth has the advantages that the angle of the cutting edge at the front end of the cutter tooth body is increased, the included angle of the cutting edge front end is close to a right angle, in this way, the situation that the cutting edge front end at the front end of the cutter tooth body is sharp and stabs the skin can be avoided under the condition that hair guiding is not affected, and the use safety of a trimming tool is improved. Meanwhile, the cutting edge angle on one side or two sides of the cutter tooth body is gradually reduced from the cutting edge front end to the cutting edge tail end to form gradual smooth transition, and after hair enters from the cutting edge front end, the closer to the cutting edge tail end, the sharper the cutting edge angle and the higher the cutting sharpness are, so that the trimming benefit and the trimming effect of the hair can be effectively ensured.

Description

technical field [0001] The present invention relates to a knife tooth, and more specifically relates to a knife tooth with a gradually changing sharp-angle cutting edge, which is mainly used in trimming tools for trimming hair. Background technique [0002] For the convenience of hair trimming, one side or both sides of the cutter tooth on the existing trimming tool are provided with a blade, and the blade is formed by an acute angle formed between the inclined surface and the bottom working surface of the cutter tooth. The blade of existing knife tooth such as figure 1 , figure 2 As shown, the blade angles of the root and the top of the cutter tooth are consistent, although it can facilitate the production and processing of the blade, improve production efficiency, and ensure the trimming effect of the pruning tool. However, during use, the blade on the top of the knife teeth is very easy to pierce the skin, causing injury to the user and affecting the safety of the prun...
