The present invention relates to an electric nail art file machine used to clean nails or toenails or to process the shape of artificial nails. It's about a nail art file machine that keeps it running.

In general, nail art refers to a series of acts of trimming nails or toenails into various shapes or drawing various patterns or characters on the nails or toenails. Such nail art has been popularized for decades in developed countries such as the United States and Europe, and even in Korea, it has recently been in the spotlight as a means for expressing one's personality among young women.

As the interest in nail art is increased as described above, an electric nail art file machine is used to help shape a nail or artificial nail more easily and accurately in a desired shape.

That is, when the polishing rod is forced in the direction perpendicular to the axis by contact with the nail, the polishing rod simply inserted in the straight direction in the insertion slit moves finely. On the other hand, in the case of the polishing rod rotates at a high speed, the fine movement of the polishing rod is accelerated, and the polishing rod is frequently removed from the main body during the use of the pile machine.

In addition, the conventional polishing rod shaft is coupled to the motor shaft with a linear shaft of a circular cross section simply inserted into and inserted into the insertion slit, so that a rotational slip phenomenon occurs between the shaft of the motor shaft and the polishing rod, thereby rotating the motor. There was a problem that the rotational force is lost because it is not transmitted to the polishing rod as it is.

In addition, if the number of times of mounting and removing the polishing rod is increased by using the pile machine for a long time, the hole of the insertion slit into which the polishing rod is inserted is loosened, or the elasticity of the binding spring surrounding the outside of the insertion slit decreases, so that the polishing rod is more easily removed from the body. There was a drawback to this situation, which resulted in a failure to function as a file machine.
