れる。(Prior Art) A tilling claw for plowing soil is usually fitted into a tilling claw holder provided on a tilling shaft of a tiller, and a central portion of a side surface is fastened (fastened) with a bolt nut (fastener). And is supported. This requires time and effort for fastening with fasteners. There is also the drawback that the fastener will loosen. Therefore,
As a support structure for a tilling claw that supports a tilling claw on a tilling claw holder without using fasteners such as bolts and nuts, for example, a pinching support type in which the base end of the tilling claw is pressed and supported by the tilling claw holder. There is a support structure for tillage nails. This pinching support type tiller claw support structure has a tiller claw holder in which inclined walls are formed symmetrically so that the inner wall space becomes narrower toward both ends, and a tiller claw holder is fitted and inserted into the tiller claw holder to have a width toward both ends. And a cultivating claw (base end) whose inclined surface is formed symmetrically so that The tiller claw holder and the tiller claw are fixedly connected to each other by a support pin (fastener) through which the tiller claw is inserted so as not to drop due to gravity. When the tiller shaft is rotated, the tiller claw receives the soil tilling reaction force, the inclined surface of the tiller nail bites into the inclined wall of the tiller holder (wedge action), and the tiller claw is pressed by the tiller holder (pressed). ) Is fixed and supported.

があった。(Problems to be Solved by the Invention) However, in such a conventional support structure for a claw support type tilling claw, the tilling claw is fixed by a cleaving force (pressing) by a wedge action by the tilling claw holder.・ I supported it.
For this reason, in order to remove the tilling claw from the tilling claw holder, it is necessary to release the straining state by hitting the blade portion of the tilling claw with a hammer in the direction opposite to the soil tilling reaction force. Therefore,
If you tap the blade of the tillage nail in the opposite direction,
In turn, the tiller is rotated in the opposite direction relative to the tiller holder. For this reason, the tilling claw is pressed by the tilling claw holder, and again fixed and supported by the tilling claw holder. Therefore, in order to remove the tilling claw, it is necessary to hit it again with an appropriate force toward the soil tilling reaction force direction, and there is a problem that the removing of the tilling claw is complicated and cannot be easily performed.
