[Industrial applications]

 The present invention relates to an electric belt claw grinder that grinds claws while running a claw sharpening belt.

[0002]

[Prior art]

 Conventionally, there are various types of nail clippers that cut and polish long stretched nails, and in particular, electric nail grinders that use a motor as a drive source include No. 58-35301 It is known that Japanese Utility Model No. 58-143610. In each of these grinders, a disk-shaped grindstone is attached to the tip of the motor rotation shaft to scrape the claw, and the tip of the toe is pressed against the surface or side surface of the grindstone that rotates at high speed to perform grinding.

However, when the tip of a toe is pressed against a rotating disc grindstone for grinding, the material of the grindstone is hard, so when the wheel is rotated at a high speed, the scratches or dents formed on the surface of the grindstone may hit or be caught by a long stretched toe. A long extended toe may be broken or the tip surface of the nail may be peeled off, damaging the toe.

[0004]

[Problems to be solved by the device]

 As mentioned above, since the disk-shaped grindstone that rotates with the motor is hard and rotates at high speed, if the long toe of a woman gets caught in the dent formed on the surface of the grindstone, the toe will crack or peel off. It may scratch your nails. Furthermore, it is difficult to adjust the strength with which the tip of the toe is applied to the grindstone.If the tip of the toe is ground too hard, the tip may be deeply nailed or cracked. In order to form a smooth curve, it was necessary to move the toes slightly, and it was difficult to make the toes beautiful.

In particular, in the above-mentioned Japanese Utility Model Laid-Open No. 58-35301, since the width of the grinding portion of the grindstone is thin, it is difficult to properly grind the claws, and the grinding points are concentrated in one place. However, it was uneconomical because it lacked durability and did not last long. Also, in the case of No. 58-143610, the grindstone attached to the tip of the rotary shaft is exposed to the outside of the main body, so the grinding dust of the nails scatters around and the cleaning after grinding is troublesome. have. In view of the above-mentioned conventional drawbacks, the present invention has an object to prevent nail cracking and deep nails during grinding, and grind the nails in a beautiful shape.

Can be adjusted as needed.

When the toe 55 to be ground is inserted into the claw insertion groove 20 of the protective cover 18, when the fingertip 56 is brought into contact with the thick plate portion 19 located at the peripheral portion of the claw insertion groove 20, the fingertip 56 Since it does not enter deeply, the insertion amount of the tip of the claw 55 becomes shallow, and the tip of the toe can be ground shallowly. Further, since the thickness of the protective cover 18 other than the plate thickness portion 19 is thin, the fingertip 56 comes closer to the grinding belt 43, the insertion amount of the toe 55 becomes deeper, and the toe can be ground deeply.

By forming the claw insertion groove 20 slantingly and slenderly, the toe 55 is moved while inclining to the left and right, and the entire surface of the grinding belt 43 is used for grinding. Since the toe of the grinding belt 43 is contacted so as not to hit the rotation direction of the grinding belt 43 at a right angle but at an angle, the toe of the grinding belt 43 is caught in the running direction and only one place is intensively ground. Instead, it is possible to finish a nail with a beautifully curved toe while sequentially changing the contact angle of the toe.

The grinding belt 43 is circulated between the driving pulley 36 and the driven pulley 40, and the driven shaft 39 is elastically repulsed by the spring 41 in the direction opposite to the driving pulley to tension the grinding belt 43. As a result, slipping of the grinding belt 43 can be prevented. Further, when the tip of the claw 55 is pressed against the grinding surface of the grinding belt, the grinding belt 43 bends following the curved shape of the toe, so that the toe does not break or peel off and the toe becomes a beautiful curve. Can be finished.

In order to grind the tip of the claw 55, first, the surface is ground by a grinding belt 43a having a rough surface to adjust the shape, and after finishing the grinding, the claw insertion groove located on the grinding belt 43b having a fine surface for finishing. By simply replacing the toe with 20, the grinding finish can be done easily. Further, when the surface of the claw 55 is ground, when the upper surface of the fingertip is aligned with the recessed part 13 provided on one side of the lid body 11, the tip of the claw 55 has an opening 24 provided on the back surface of the protective cover 18. When the grinding belt 43 running inside the opening is brought into contact with the grinding belt 43, the grinding belt is pushed into the surface of the claw 55 while contacting the concave guide portion 59 provided on one side of the guide plate portion 17. Can be polished into a beautiful arc shape.

The rotation speed of the grinding belt 43 can be changed by changing the variable resistance of an inverter or the like which is interlocked with the switch 31, and the rotation speed of the motor can be changed. Can grind the baby's weak nails at a slower speed and safely.

When replacing the grinding belt 43, after removing the protective cover 18 and the dustproof cover 23, respectively, when the operation switch 57 provided on one side surface of the main body 1 is pushed, the driven shaft 39 is pushed and the spring is pushed. It is possible to easily replace the grinding belt 43 by loosening the tension of the grinding belt 43 by moving it in the direction of the motor shaft 33 along the bearing long grooves 6 and 15 against the elastic force of 41. In addition, when the toe nail is ground, it is not recommended to insert it in the nail insertion groove 20 of the protective cover 18. Therefore, the dustproof cover 23 may be removed and the grinding belt 43 portion may be exposed so as to be ground.
