Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an electric nail care machine, in which a nail care section such as a polishing section is reversed to a movable section which is reciprocally driven by a drive section. It is designed to be installed.

(Prior art example) The present applicant has previously proposed a new electric nail polisher (Japanese Patent Laid-Open No. 62-142502). This is configured such that a polishing portion is attached to the lower end of the main body case, and the nail polishing is performed by holding the main body case and reciprocatingly driving the polishing portion by a drive portion. .

(Problems to be solved by the invention) The polishing part is capable of crushing the cuticle of the base of the nail with its tip surface, but if the cuticle of the cuticle is repeatedly crushed with the same tip surface, The surface gradually wears and deforms. Further, the entire polishing surface is not always used uniformly, and especially the front end side or the rear end side is used exclusively depending on the habit of the user. It wears out and often requires replacement of the nail care area.

Therefore, it is an object of the present invention to provide means for preventing the wear deformation from increasing due to the use of only a specific portion of the nail care portion such as the polishing portion.

(Means for Solving Problems) In the present invention, the nail care unit 3 provided in the main body case 1 is reciprocally driven by the drive unit 27, and the nail care unit attached to the movable section 5 is moved. An engagement formed by a concave portion and a convex portion between the facing surfaces of the claw grooming portion 6 and the movable portion 5 and at a circumferential position around the center of the movable portion 5. Means is provided, and the engaging means is formed such that the concave side is continuously formed in the circumferential direction, and the convex side in the engaged state is rotationally guided, so that the pawl care section 6 is engaged with the movable section 5. Up to now, it can be freely rotated horizontally, and can be mounted by reversing the front-back direction, eliminating the trouble of attachment and detachment of the nail care section 6 and the possibility of loss, and enabling the user to continuously use it properly. .

(Operation and Effect) In the above-mentioned configuration, when the drive unit 27 is driven while holding the main body case 1, the nail care unit 6 is driven by the drive unit 27 and reciprocates. Then, the nail care section 6 is pressed against the nail a to polish the nail.

By the way, for example, when the tip surface 6a of the nail care section 6 is pressed against the cuticle and the cuticle crushing process is repeated,
6a gradually wears and deforms. Alternatively, when the polishing surface 19 of the nail care section 6 is applied to the nail a to polish the nail, the polishing surface 19 is not necessarily used uniformly on the entire surface, and especially depending on the user's habit, the tip side or The rear end side is used exclusively, and the frequently used parts wear out quickly. In such a case, the nail care section 6 is separated from the movable section 5 while the engaging section 21 is engaged, and then the nail care section 6 is horizontally rotated about the axis to reverse the front and rear of the nail care section 6,
If the movable part 5 is mounted so as to return to the original state, the above-mentioned problems can be solved by making the rear end side up to that point the front end side, and the entire nail care part 6 can be used without waste.
