Technical Field
[0001] The utility model relates to the technical field of scissors, in particular to a pair of scissors with waisted teeth and a structure for preventing hair from being scratched. Background Art
[0002] Hairdressing dental scissors are composed of two blades, a static blade and a dynamic blade. One of the static blades is made into a toothed blade, and the other dynamic blade is made into an arc-shaped blade. Because there are gaps between the teeth on the toothed blade, in order to avoid sticking of the teeth when the two blades are engaged with each other, the edge of one of the blades needs to be properly chamfered. When cutting hair, the two blades shear and cut the hair through the engaged part. The amount of hair removed by the dental scissors is mainly determined by factors such as the tooth shape, the ratio of the tooth width and the tooth gap.
[0003] According to the processing technology, tooth scissors are divided into ordinary tooth scissors and safety tooth scissors. Ordinary tooth scissors are designed with a sharp moving blade and a dull static blade. Therefore, the sharp moving blade of ordinary tooth scissors will scratch the hair in the teeth gap, making the hair rough; safety tooth scissors are processed into a dull moving blade and a sharp static blade, so the dull moving blade of safety tooth scissors will not scratch the hair in the teeth gap. Therefore, it is necessary to design a hairdressing tooth scissors that can prevent scratching of hair. Utility Model Content
[0004] The utility model aims to prevent the tooth scissors from scratching or pulling hair, increase the width of the intersection of the tooth root and the closed blade, and process the intersection of the tooth gap and the blade edge into a blunt blade edge, so that the tooth scissors can be pulled and picked at will without scratching the hair or pulling the hair by the blade edge.
[0005] In order to achieve the above-mentioned purpose, the method adopted by the utility model is that the tooth blade and the arc-shaped cutting edge of the tooth scissors rotate with the screw hole as the central axis, and the tooth width of the tooth blade gradually increases from small to large, that is, the tooth gap gradually decreases from large to small. When the tooth scissors are completely closed, the width of the tooth blade is reduced and the width of the tooth gap is increased, so that the hair can be better discharged, and then the sharp cutting edge in the tooth gap is processed to be blunt, so that the hair can be picked and cut at will without scratching it.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-Figure 2 The present embodiment provides a structure of a pair of dental scissors with waisted teeth to prevent hair from being scratched. The structure of the pair of dental scissors with waisted teeth to prevent hair from being scratched includes:
[0020] The hairdressing dental scissors are composed of a moving blade and a stationary blade, which are hingedly arranged by a screw hole 3. The moving blade is provided with a blunt edge 23 and a sharp edge 24 on the meshing side of the stationary blade, and the blunt edge 23 and the sharp edge 24 are arranged at intervals. A plurality of comb-shaped strip teeth are provided in the middle of the stationary blade, and the tooth gap of the strip teeth is narrow in the middle and wide at both sides. The intersection of the narrow and wide strip teeth is the cutting edge intersection 26. The outer side of the strip teeth is the tooth front end 27, and the inner side is the tooth root 28. The outer boundary of the two strip teeth is the tooth gap front end 25, and the inner boundary of the two strip teeth is the tooth gap root 29.
[0021] Compared with the prior art, by changing the sharpness of the dynamic blade and the static blade, it is possible to avoid scratching the hair tails during the haircutting process by the hairdressing scissors, and by providing a plurality of tooth tips at the front end 27 of the static blade, the hairdressing scissors can be made sharper, and by widening the tooth root 28 and the intersection 26 of the blade between the two teeth, the wear resistance of the hairdressing scissors is improved while also improving the sharpness of the blade.
[0022] See also Figure 1-Figure 2 In one embodiment, the types of the dynamic blade are conventional dynamic blade 11 and improved dynamic blade 21, and the types of the static blade are conventional static blade 12 and improved static blade 22;
[0023] When a barber is cutting a customer's hair, the barber holds the hairdressing tooth scissors and rotates the movable blade and the stationary blade of the tooth scissors around the screw hole 3, and finally cuts the hair through the meshing portion of the movable blade and the stationary blade. However, for conventional tooth scissors, although the hair can be cut through the meshing portion between the conventional movable blade 11 and the conventional stationary blade 12, since the conventional movable blade 11 is a sharp blade, the hair at the cutting position will be scratched due to the inertia of the rotation of the conventional movable blade 11, thereby making the hair tail rough after trimming.
[0024] The front end 27 of the improved static blade 22 is provided with a plurality of tooth tips, and the distance between two adjacent tooth tips is equidistant, and the tooth tips are provided with chamfers;
[0025] As for the improved tooth scissors, by setting the strip teeth to be narrow in the middle and wide on both sides, the tooth gap can better arrange hair, and the blunt edge 23 and the sharp edge 24 are set at an interval, so that the blunt edge 23 will not scratch the hair, and the sharp edge 24 can maintain its sharpness for a longer time, making the shearing gentler. The improved static blade 22 and the improved dynamic blade 21 rotate with the screw hole 3 as the center axis. When the tooth scissors are engaged, the sharp edge 24 of the improved dynamic blade 21 will be hidden in the tooth root of the improved static blade 22. Therefore, the tooth scissors with an anti-scratching structure design will not scratch or pull hair, and can maintain the sharpness of the sharp edge 24 for a long time, making the shearing gentler.
[0026] See also Figure 2 In one embodiment, the static blade 22 is designed with a gradual tooth width and tooth gap structure to avoid scratching hair.
[0027] See also Figure 2 In one embodiment, a rounded corner is provided on one side of the blunt edge 23, which can play a better transition role and avoid the tooth biting phenomenon during the engagement process of the tooth scissors.
[0028] In addition to the above technical solution, the utility model also provides another embodiment. The difference between this embodiment and the above embodiment is that the dynamic blade and the static blade are both made of high-carbon steel used for hairdressing scissors and pet scissors. By improving the material and workmanship accuracy of the hairdressing scissors, the smoothness of hair cutting can be further improved and hair scratches can be avoided.
[0029] The working principle of the utility model is:
[0030] In this embodiment, when the barber is cutting the hair of the customer, the barber holds the hairdressing tooth scissors and rotates the moving blade and the stationary blade of the tooth scissors around the screw hole 3, and finally cuts the hair through the meshing portion of the moving blade and the stationary blade; for the conventional tooth scissors, although the hair can be cut through the meshing portion between the conventional moving blade 11 and the conventional stationary blade 12, since the conventional moving blade 11 is a sharp blade, the conventional moving blade 11 is rotated around the screw hole 3 and meshed with the conventional stationary blade 12, and the hair at the cutting position is scratched due to the inertia of the conventional moving blade 11, thereby making the hair tail rough after trimming, and the improved tooth scissors In terms of the improved moving blade 21, the improved static blade 22 is sharp while the improved moving blade 21 is not sharp. By rotating the improved moving blade 21 around the screw hole 3, the inertia of the improved moving blade 21 will not scratch the cutting position of the hair during the rotation of the improved moving blade 21. By arranging a plurality of tooth tips at the front end 27 of the teeth of the improved static blade 22, the improved static blade 22 can be made sharper. By arranging chamfers at the tooth tip positions, the tooth biting between the improved moving blade 21 and the improved static blade 22 can be avoided. By widening the tooth root 28 and the cutting edge intersection 26 between the two teeth, the tooth scissors can be kept sharp while making the cutting edge angle more reasonable, thereby increasing the service life of the hairdressing tooth scissors.
