A female screw accommodating portion 12 is provided for mounting the female screw 20 in a position movable in a direction perpendicular to the axis.

That is, the female screw accommodating portion 12 is formed to have a width and a width slightly larger than the width and the width of the female screw 20.

The female screw 20 is inserted into the female screw accommodating portion 12 in the process of positionally moving the female screw 20 in the direction perpendicular to the axis of the hollow H to adjust the fastening position with the male screw B, The stopper 13 is integrally formed so as to prevent it from falling into the hollow H out of the state.

That is, the four sides of the female screw accommodating portion 12 are formed so as to pass through the hollow H of the casing vertically so that the four side edges of the female screw 20 are inserted.

Here, the concavity and convexity 11 may be formed by forming a polygonal shape around the outer surface of the casing 10 so as to generate a frictional force against rotation torque, or the cross-sectional shape of the rim may be either spline or serration In particular, the convex portion of the concavity and convexity 11 may be formed in a wedge shape or a saw-tooth shape which is inclined in a direction opposite to the insertion direction of the mounting object with respect to the mounting hole.

The casing 10 is symmetrically divided about the axis of the hollow H so that the female threaded portion 12 can be easily formed and formed and the insertion of the female thread 20 is facilitated. .

In this case, injection molding can be performed in the form of bisecting the center portion of the casing 10, and one end of the opposing surfaces can be integrally formed without being completely divided by being connected to the line hinge 14 so as to be folded or unfolded. And the other (opposite) end may be formed correspondingly with the engaging groove 15 and the engaging projection 16, which are coupled in an interference fit manner to fix and hold the folded state.

The female screw 20 is inserted into the female screw housing portion 12 in the hollow H of the casing so that the female screw 20 can be slightly moved in the direction perpendicular to the axis of the hollow H and can not be rotated.
