And an insertion hole for fitting the tip portion of the horizontal bar portion drilled in the side wall.

In the attachment for the root clamp according to the present invention, when the rotation center of the L-shaped screw portion is coaxial with the rotation axis of the rotary tool, the holding portion is located at a position slightly deviated from the rotation center. Because the center of the holding part comes, it is possible to rotate the rotary tool without difficulty by attaching it to the rotary shaft of the rotary tool via a connecting part that is crank-shaped or inclined at a predetermined angle. Is also a feature.

In the attachment for the root clamp according to the present invention, when the holding portion is coaxial with the rotation center of the L-shaped screw portion with respect to the rotation axis of the rotary tool, the rotation center and the center of the holding portion are arranged. In order to match, the holding means of the horizontal bar portion bent to the L-shape of the L-shaped screw portion of the root clamp is formed inside the open end of the cylindrical body, and the rotation of the L-shaped screw portion It is also characterized in that the rotation operation of the rotary tool can be performed without difficulty by matching the center with the center of the holding portion.

According to the attachment for the root binding clamp according to claim 1, since the L-shaped screw portion of the root binding clamp can be mounted on the cylindrical main body without difficulty, the root binding clamp can be quickly and easily installed using a rotary tool. It is possible to provide a root clamp attachment that can be turned efficiently.

According to the attachment for the root clamp according to claim 2, the rotation axis of the rotary tool and the rotation center of the L-shaped screw portion can be made coaxial, and the rotation operation of the rotary tool can be performed smoothly and effortlessly. become able to.
According to the attachment for the root binding clamp of claim 3, the holding means for the horizontal bar portion bent into the L shape of the L-shaped screw portion of the root binding clamp is formed inside the opening end of the cylindrical body, By making the rotation center of the L-shaped screw part coincide with the center of the holding part, the rotation operation of the rotary tool can be performed without difficulty.

The schematic perspective view for demonstrating embodiment of the attachment for root clamps of this invention. The end view. The schematic perspective view which shows 2nd Example. The end view which shows 3rd Example. (A) is a side view of a root clamp operated by the root clamp attachment of the present invention, and (b) is a plan view thereof.

Next, an embodiment according to the root clamp attachment of the present invention will be described in detail with reference to FIGS.

As shown in FIGS. 1 and 2, the attachment for the root curl clamp according to the first embodiment includes a cylindrical main body 11 and a holding part for connecting and holding the L-shaped screw part 102 of the root curl clamp 101 provided at the opening end thereof. 12 and a connecting portion 13 between the cylindrical main body 11 and a rotary tool provided at the other end.
A polygonal hole 14 that can engage with various nut portions is formed inside the holding portion 12, and an outer periphery of the connecting portion 13 is formed as a polygonal column 15 that can be engaged with a holder of a rotary tool.

The holding portion 12 includes a concave groove 16 and an insertion hole 17 formed on one side wall of the opening end of the cylindrical main body 11, and the concave groove 16 has an L-shaped screw portion of the root clamp 101. A horizontal bar portion 103 bent into an L-shape is inserted into the insertion hole 17, and a distal end portion of the horizontal bar portion 103 formed in a side wall facing the concave groove 16 is inserted into the insertion hole 17.
Therefore, by rotating the rotary tool using a motor, hydraulic pressure, etc., the horizontal bar portion 103 of the L-shaped screw portion 102 of the root binding clamp 101 is rotated horizontally by the holding portion 12 of the root clamp attachment, The L-shaped screw portion 102 is rotated to tighten the root clamp 101 at a predetermined position.

In the attachment for the root clamp according to the second embodiment shown in FIG. 3, when the holding portion 12 is coaxial with the rotation center 22 of the L-shaped screw portion 102 with respect to the rotation shaft 21 of the rotary tool, Since the center of the holding part 12 comes to a position slightly deviated from the rotation center 22, it is attached to the rotary shaft 21 of the rotary tool via a connecting part 13 which is crank-shaped or inclined at a predetermined angle. The rotation operation can be performed without difficulty.
Therefore, by rotating the rotary tool using a motor, hydraulic pressure, or the like, the horizontal bar portion 103 of the L-shaped screw portion 102 of the root-clamping clamp is rotated horizontally by the holding portion 12 of the root-clamping attachment, and L The character-like screw portion 102 is turned to tighten the root clamp 101 at a predetermined position.

In the attachment for the root clamp of the third embodiment shown in FIG. 4, the holding portion 12 rotates when the rotation center of the L-shaped screw portion 102 is coaxial with the rotation shaft 21 of the rotary tool. In order to make the center and the center of the holding portion 12 coincide with each other, the holding means for the horizontal bar portion 103 bent into the L-shape of the L-shaped screw portion 102 of the root clamp inside the open end of the cylindrical main body 11 Is formed.
By doing so, the rotation center of the L-shaped screw portion 102 and the center of the holding portion 12 coincide with each other, and the rotation operation of the rotary tool can be performed without difficulty.

As the holding means, a U-shaped guide groove 31 formed inside the open end of the cylindrical main body 11 is shown in the figure. The guide groove 31 includes both side walls 32 and 32 into which the horizontal bar portion 103 of the L-shaped screw portion 102 of the root clamp is fitted, and a notch 33 provided on a surface facing the insertion hole 17. 33 is formed slightly higher than the bottom surface of the guide groove 31.

Accordingly, the L-shaped threaded portion 102 of the root curling clamp is dropped into the notch 33 portion of the guide groove 31, the tip of the horizontal bar portion 103 is fitted into the insertion hole 17, and then the root of the guide groove 31 is reached. By fitting the L-shaped screw portion 102 of the clasp clamp, the horizontal bar portion 103 bent into the L-shape of the L-shaped screw portion 102 of the clasp clamp can be fitted into the holding means.
Then, by rotating the rotary tool using a motor, oil pressure, etc., the horizontal bar portion 103 of the L-shaped screw portion 102 of the root-clamping clamp is rotated horizontally by the holding portion 12 of the root-clamping attachment. And the rotation operation of the rotary tool is performed in a state where the center of rotation of the L-shaped screw portion 102 and the center of the holding portion 12 coincide with each other, and the L-shaped screw portion 102 is rotated without difficulty to clamp the root. Is tied to a predetermined position.

Since the attachment for the root curl clamp of the present invention is configured as described above, it goes without saying that it can be applied not only to the root curl clamp but also to various other L-shaped clamps.
