Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electric clipper for beard trimming that can also be used for shaving or cutting hair.

[Conventional technology]

2. Description of the Related Art Electric hair clippers specifically designed for beard trimming have been known for some time. This electric clipper for beard trimming is narrower and smaller than a general electric clipper for cutting hair, and is used with a trimming height adjustment attachment. The attachment is formed into a cylindrical shape with comb teeth, and is inserted into the tip of the clipper body, which has a fixed blade and a movable blade, and adjusts the cutting height by changing the distance between the blade and the blade. It's getting old.

[Problem that the invention attempts to solve]

Such electric hair clippers for beard trimming are narrow and small, so they are suitable for, for example, shaving the small heads of infants or cutting the hair of adults.

However, if an electric hair clipper exclusively used for beard trimming is to be used as it is, for example, for shaving or cutting the hair of a small child, there will be some difficulties in actually handling it. That is, when a person holds clippers in their own hands to trim their beard, and when shaving a toddler's head, the direction in which the blade of the clippers is held is opposite. When cutting a beard, the blade is pointed toward one's own face, but when cutting the hair of a child or another person, the blade is turned in the opposite direction. Therefore, when using the former method and when using the latter method, even on the outer surface of the same clipper, the position where the thumb of the gripping hand rests is naturally different, and it is not easy to use if only one method is used. It is easy to make mistakes during operation.

This invention was devised to solve this problem, and aims to improve usability when using one electric clipper for both beard trimming, round shaving, and cutting of hair.

[Means for solving problems]

In this invention, the operation knob 18 provided on the cutting height adjustment attachment 2 is connected to the front and back sliding movement of the switch operation knob 8 on the clipper body 1, and then each of the fixed blade 4 and the movable blade 5 is connected. The switch operation knob 8 is disposed on the upper surface 1a side of the clipper body 1 facing the cutting edge, and the operation knob 18 of the cutting height adjustment attachment 2 is disposed on the opposite lower surface 1b side.

[Effect of idea]

According to the present invention configured as described above, when a person wears the cutting height adjustment attachment 2 and trims his or her own beard, regardless of whether he or she is right-handed or left-handed, the hand that grips the clipper body 1 is fixed. Since the thumb of the user is placed on the lower surface 1b of the clipper body 1 where the operating knob 18 of the attachment 2 is located, the switch operation and the attachment 2 can be easily performed while gripping the clipper body 1. Also, when removing the attachment 2 to shave a toddler's hair, whether the person is right-handed or left-handed, the thumb of the hand holding the clipper body 1 should be placed on the top surface of the clipper body 1 where the switch operation knob 8 is located. Since it can be hung on the 1a side, it has the advantage of being easy to use, similar to when shaving the beard.
