Description

[Detailed Description of the Invention] The present invention relates to a hair clipper, which is capable of selectively performing round cutting and plowing by moving the comb-shaped part of the wedge-shaped plow body forward and backward between the blade parts of the clipper blade body. This invention relates to a holding structure for a comb-shaped plow body.

In conventional hair clippers of this type, for example, % Kaimei 51-
As shown in Fig. 7 described in Japanese Patent No. 141068, in order to be able to perform hair cutting in addition to ordinary hair styling such as round cutting, a comb that closes the space between the clipper blades of the clipper case body is used. A structure was adopted in which the formed comb-shaped plow body was removably attached to the clipper blade part of the case body as an attachment, but this structure required the plow body to be attached as an attachment when mowing. However, there have been problems such as time-consuming and complicated work, and troublesome storage of attachments.

For this reason, a comb-shaped plow body is incorporated into the teeth body so that it can move forward and backward.
A hair clipper has been developed in which a comb-shaped section at the tip of a comb-shaped plow body is advanced and retreated between the blade sections of a clipper blade body, thereby enabling selective round-cut and deep-cut hair styling.

With this structure in which the comb-shaped comb body advances and retreats, it is required that the holding force of the comb body be made thick so that the comb body does not accidentally retreat when hair is styled when the comb body is advanced. Like the clipper described in the publication, it is necessary to screw the comb-shaped body so that it can slide with a spring interposed, resulting in a complicated structure, poor assembly performance, and poor operability. become.
