Problems solved by technology

[0003] Because hairdressing scissors have high requirements on the precision of the blade, and some hairdressing scissors have tooth-like structures on the blades, even professional sharpening masters are very likely to wear out the tooth-like structures, resulting in the scrapping of the entire hairdressing scissors. The sharpening body of the tool has roughness, mainly by grinding to make the cutting edge sharper, so dust will be generated during use. Long-term grinding work is not only not environmentally friendly, but also harmful to the operator's body. An edge protector for precise sharpening and zero dust, especially for hairdressing scissors

[0029] like figure 1 As shown, the portable edge protector of the embodiment of the present invention comprises:

[0030] A set of edge protection units 1 , the edge protection unit 1 includes a first sharpening sphere 11 and a second sharpening sphere 12 that are tangential. The specifications of the first sharpening sphere 11 and the second sharpening sphere 12 are not limited, and the ball diameters of the first sharpening sphere 11 and the second sharpening sphere 12 can be the same or different, according to actual conditions, such as cutting tools specifications for design.

[0031] The material of the first sharpening sphere 11 and the second sharpening sphere 12 is preferably zircon material with high hardness. Of course, the usual sharpening material can also be used, but the usual sharpening material is more consuming.

[0032] A fastening device, the fastening device fixes the first sharpening sphere 11 and the second sharpening sphere 12 so that the first sharpen...

[0052] In the structure of the portable edge protectors of the first embodiment and the second embodiment, a vibrating device can be further provided to drive the fastening device and the edge protection unit to vibrate to accelerate grinding. The portable edge protector of the first embodiment will be described below as an example.

[0053] like image 3 As shown, the vibrating device includes a detachably connected working part 31 and a handle part 32 , and the working part 31 drives the fastening device and the edge protection unit 1 to vibrate.

[0054] The working part 31 can adopt a columnar structure, such as a nylon rod. The working part 31 includes a motor part 311 and a mounting part 312. The motor part 311 and the mounting part 312 are isolated to prevent water from entering the motor part through the mounting part 312 and damaging the motor. The motor part 311 is provided with a vibration motor (not shown in the figure), and the type of the vibration motor is not...

Abstract

The invention discloses a portable cutting edge protector. The portable cutting edge protector comprises at least one cutting edge protection unit and a fastening device, wherein each cutting edge protection unit comprises a first sharpening sphere and a second sharpening sphere which are tangent; and the fastening device fixes the first sharpening spheres and the second sharpening spheres so thatthe first sharpening sphere and the second sharpening sphere can always be tangent. According to the technical scheme, the cutting edge protector has the advantages of being simple to operate, high in practicability, high in precision, high in safety coefficient, convenient to carry and the like, and the protector generates no dust and is environmentally friendly in the sharpening process.

Description

technical field [0001] The invention relates to the field of knife care, in particular to a portable edge protector. Background technique [0002] As a daily necessities, knives will gradually become dull during use. Especially in the hairdressing industry, hairdressing scissors are used every day. Such a high frequency of application leads to faster wear of hairdressing scissors. In addition, the sharpness of hairdressing scissors directly affects customer experience. Therefore, the daily care of hairdressing scissors is particularly important. important. [0003] Because hairdressing scissors have high requirements on the precision of the blade, and some hairdressing scissors have tooth-like structures on the blades, even professional sharpening masters are very likely to wear out the tooth-like structures, resulting in the scrapping of the entire hairdressing scissors. The sharpening body of the tool has roughness, mainly by grinding to make the cutting edge sharper, so...
