Description

Height adjustment and folding device for whetstone stand {Supporter of a grindstone}

In general, when grinding a knife or sickle used for cutting, the grinding is performed using abrasive stone / grindstone. In this case, grooves are cut into wood as a means of fixing the abrasive stone or grindstone, or a certain mold is made of synthetic resin. It was produced to fix the abrasive stone / grinding wheel.

Conventional whetstone pedestal supports only the abrasive stone / whetstone in supporting the abrasive stone / grinding stone, but did not support that the pedestal shake or flow occurs. Therefore, not only was the delay of knife polishing work, but the blade was worn again due to the shaking and the phenomenon of frequently stopping knife polishing frequently occurred.

Also, among the grindstone pedestals on the market, it supports the whetstone fixing plate supported by the elastic spring.

Hold the mold leg and press it inward to open the whetstone fixing plate, and then insert the whetstone inside to fix the knife.

When the stone is fixed by opening the whetstone fixing plate by pressing the mold legs inward, the width of the legs attached to the whetstone fixing plate is narrowed, so that the whetstone pedestal is shaken when the whetstone is polished. In particular, the wide grinding wheel

If you hold the mold legs and press the wide grinding wheel inside, the width of the legs becomes narrower and unstable, so that the grinding wheel stand was more shaken.

As well as on the whetstone

Since the type legs are integrally attached, it is difficult to load them when they are bulky and take up a lot of loading space.

The present invention has been devised to solve the problems as described above, by inserting the whetstone to open the whetstone fixing plate that is retracted by the restoring spring, the bending support for fixing the whetstone is bent at a certain length from the top Since the parts are bent outwardly to form, even if the wide grinding wheel is fixed inside the whetstone fixing plate, the width of the back of the bending support is widened so that the knife can be polished in the stable condition. Do it.

In addition, the present invention is to adjust the height of the rear part of the whetstone fixing plate by screwing the bending support that is screwed to the rotary connector mounted on the rear of the whetstone fixing plate for the purpose of being used after fixing with a butterfly nut It is done.

In addition, the present invention is because the bending support mounted on the rear of the whetstone fixing plate can be folded and unfolded in the whetstone fixing plate, so that it can be folded and stored during storage or transportation, thereby reducing the loading space.

In addition, an inner surface of the whetstone fixing plate is fitted with a rubber plate to fix the whetstone, so that the whetstone does not slip on the whetstone fixing plate.
