Abstract

PURPOSE: To eliminate the need for grinding of upper and lower blades and to improve work efficiency. CONSTITUTION: Upper blade 4 and lower blade 6 slide upon each other, and upper blade 4 moves left and right for clipping hair. On the sliding surfaces of upper blade 4 and lower blade 6, there are upper replacement blade 15 and lower replacement blade 16, which are so installed that they may be detached as required for replacement.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual and electric hair clipper having a replaceable replacement blade.

[0002]

2. Description of the Related Art A pair of upper and lower blades are slidably contacted with each other, and hair is cut by reciprocating left and right of the upper blade. A sliding blade is provided to replace the sliding surface of the slidably contacting blades. Has never existed.

[0003]

The blade portions of the upper and lower blades of the conventional manual and electric hair clippers are in slidable contact with each other, and one of the upper blades reciprocates left and right. As a result, the blade becomes difficult to cut due to wear and the like. Therefore, polishing must be performed to improve sharpness, but this polishing operation is extremely difficult. Therefore, improvement is demanded.

[0004]

SUMMARY OF THE INVENTION In view of such a situation, the present invention addresses this problem by providing detachable replacement blades on the corresponding sliding surfaces of the upper and lower blades of the hair clipper. The replacement blade is provided for the purpose of saving polishing and improving work efficiency.

[0005]

In the case of the manual hair clipper, the present invention operates the handle 1,11.
The upper blade 4 reciprocates left and right while slidingly contacting the lower blade 6 by the above operation, and the upper and lower blades 4 have upper and lower replacement blades 15 and 16 which are replaceable on the sliding surface. 1
8 and the locking holes 15a and 16a are replaced by appropriate means such as abrasion of the sliding surface so as to eliminate polishing work and improve sharpness to improve work efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of a manual hair clipper according to the present invention, which will be described below with reference to the drawings.

Reference numeral 1 denotes an operating handle, which has a protruding strip 3 projecting downward at the tip of a mounting body 2 provided at the tip of the operating handle 1. The protruding strip 3 is provided on the upper surface of the upper blade 4. The upper blade 4 is slidably fitted in the lateral sliding groove 5 and slides using the protruding strip 3 as a guide.

A lower blade 6 is provided with a through hole 8 through which a bolt 7 is inserted, and is fixed by a nut 10 through a through hole 9 formed in the upper blade 4. The engaging recess 4 into which the locking piece 12 provided at the tip of the operation handle 11 is fitted.
a is provided, the locking piece 12 is fitted into the engaging recess 4a, and the upper blade 4 is slid by the operation of the operating handle 11.

The operation handle 11 is pivotally supported on the operation handle 1 by a shaft 13 through a through hole 6a formed in an end portion of the lower blade 6. Further, the coil spring 1 is provided between the operation handles 1 and 11.
4 is provided.

Further, the upper sliding blade 1 and the lower sliding blade 6 are replaceable on the sliding surfaces, that is, the lower surface and the upper surface, which face each other.
5 and the lower replacement blade 16 are detachably attached by an appropriate means.
For example, each of the upper blade 4 side and the lower blade 6 side has a plurality of planted pin-shaped protrusions 17 and 18.
Is an upper replacement blade 1 that is placed on the lower and upper surfaces of the upper blade 4 and the lower blade 6.
5 and the lower replacement blade 16 are provided so as to be fitted into the locking holes 15a and 16a formed by facing the projections 17 and 18 to each other.

In the above description, the manual hair clipper has been described, but it goes without saying that a replacement blade can also be used for an electric hair clipper.

[0012]

As described above, according to the present invention, the workability can be improved by providing the upper and lower replacement blades which are replaceable on the opposite sliding surfaces with which the upper and lower blades are slidably contacted, and which can be replaced if necessary. Moreover, there is an effect that the polishing work which has been conventionally performed is unnecessary and there is no troublesome trouble.
