And, at the center of the gripping surface (31a, 31b) of any one of the upper and lower gripping parts (30a, 30b), there is a rotary coupling groove (35) corresponding to the rotary coupling piece (77). This is formed.

In addition, at least one rotation groove (35a) corresponding to the rotation piece (77a) is formed on the inner periphery of the rotation coupling groove (35), and the rotation piece (77a) is rotated in the rotation direction with respect to the rotation groove (35a). ) is formed to extend the rotation space (35b) in which it rotates.

Here, the rotation coupling groove 35 and the rotation coupling piece 77 are preferably formed in a circular shape, but are not limited thereto.

By the structure described above, the rotary piece 77a inserted into the rotary groove 35a is rotated into the rotary space 35b by the rotation of the rotary engaging piece 77, so that the fixing pin 71a is attached to the upper gripper ( 30a) can be fixed.

Hereinafter, the process of installing the fixing pin on the gripping surface of the clamp for fixing the hole according to the sixth embodiment of the present invention will be briefly described with reference to FIGS. 15 and 16.

First, the operator selects a fixing pin (71a) with a diameter or size corresponding to the plurality of holes (5a, 5b) arranged to overlap, and rotates the selected fixing pin (71a) protruding from the rotary coupling piece 77. After positioning the piece (77a) corresponding to the rotation groove (35a) of the rotation coupling groove (35), the rotation coupling piece (77) of the fixing pin (71a) is placed in the rotation coupling groove (35) formed on the gripping surface (31a). ) is combined with.

In this way, with the rotary coupling piece 77 coupled to the rotary coupling groove 35, the rotary coupling piece 77 is rotated to move the rotary piece 77a located in the rotary groove 35a into the rotation space 35b. Rotate it inward to fix the fixing pin (71a) to the upper gripper (30a).

Here, the rotation space 35b is preferably formed in a clockwise rotation direction with respect to the rotation groove 35a, but may also be formed in a counterclockwise direction, but is not limited thereto.

In addition, in this embodiment, the rotary piece 77a of the rotary coupling piece 77 and the rotary groove 35a of the rotary coupling groove 35 are formed in two, but it is possible to form a larger number. Various other changes are possible.

Even at this time, in order to prevent the rotary piece 77a rotated in the rotation space 35b from being separated or released, at least one emboss-shaped stopper (not shown) is installed on the upper and lower surfaces of the rotary piece 77a. It may be formed to protrude, and fixing grooves (not shown) corresponding to the stopper may be formed on the inner upper and lower surfaces of the rotation space 35b.

By the above-mentioned structure, the stopper of the rotary piece 77a rotated in the rotation space 35b is fitted into the fixing groove formed in the rotation space 35b, thereby preventing the fixing pin 71a from being separated and released. The worker can apply force to rotate the fixing pin 71a in the opposite direction, thereby moving the rotary piece 77a in the rotary space 35b into the rotary groove 35a and separating it.

Above, the present invention has been shown and described in relation to specific embodiments, but it is common knowledge in the art that various modifications and changes are possible without departing from the spirit and scope of the invention as indicated in the appended claims. Anyone who has it will be able to easily understand it.
