Description

[Detailed Description of the Invention] 1) Technical Field: The present invention relates to a so-called desk sander in which a disk-shaped grindstone has its shaft mounted at a right angle to an electric motor shaft, and is particularly characterized by the structure of its grip portion, that is, the grip portion. Is to have.

2) Conventional technology, its problem: In this tool, the outer frame part of the motor is the grip part, but this outer frame part has a relatively large outer diameter, and the material of the frame is aluminum die cast, plastic, etc. The surface is relatively smooth, and it requires a considerable amount of grip to work with this grip in one hand, and it is easy to get tired for long hours, and this tendency is even greater when gloves are used. In that work, water for tile polishing, oil for work of steel products, etc. are often accompanied by factors that make it difficult to reliably hold tools such as wood chips generated in woodworking work. This difficulty in gripping may cause a risk of dropping the tool during work. Some grips have irregularities on the outer circumference, but they are still slippery when oil adheres, and the effects of these irregularities rapidly decline due to wear.

3) Means for solving the problem: Therefore, in the present invention, sandpaper is attached to the outer periphery of the gripping part of the tool with the abrasive side facing up, or an adhesive is applied between the palm and the tool. It was decided to solve the above problems by providing sufficient frictional force.

4) Embodiment: FIG. 1 is a perspective view of a desk sander to which the present invention is applied, 1 is a gripping portion thereof, that is, an outer frame portion of a motor, 2 is a disc-shaped grindstone attached to this tool, FIG. 2 3 is sandpaper to be wrapped around the outer periphery of the grip portion 1. 3 is shown in a cylindrical shape in the figure, but this is a virtual view imagining a state in which it is wound around the grip portion 1, and its original form is a cloth shape, or a tape 5 as shown in a perspective view in FIG. It is a state.
Here, 3a is the surface of the sandpaper to which the abrasive is adhered, and 3b is the back surface of the sandpaper, which is attached to the outer periphery of the grip portion 1. FIG. 4 shows the outer periphery of the grip portion 1 coated with an abrasive.

5) Effect: As described above, according to the present invention, a sufficient anti-slip effect can be produced between the sander grip and the palm, and the fingers need only hold the tool with the necessary gripping force for the work, and the slipping Since unnecessary power is not wasted in gripping power to avoid, there is little fatigue. Even if you grip this tool with an oiled rubber glove, the particles of sandpaper will break the oil film and come into direct contact with the surface of the glove, so you do not have to worry about sliding and concentrate your nerves directly on the work. You can Thus, according to the present invention, there is almost no danger of the tool slipping off during work.
