The coupling nut 200 is engaged with the coupling part 300 of the body 100 in a state where the coupling nut 200 is screwed to the coupling part 110 of the body 100. The connection nut 200 has a ring-shaped member having a hollow shape, that is, a generally known nut member shape.

A threaded portion 210 is formed on the outer surface of the connecting nut 200 so as to be screwed into the coupling portion 110 of the body 100.

The coupling nut 200 has an inner side surface formed with a locking engagement groove 220 to be inserted therein. Here, the latching protrusion 310 of the connecting rod 300 to be described later is inserted into the latching groove 220. A plurality of the engaging grooves 220 may be spaced apart from each other in a direction in which the engaging bars 300 are inserted to adjust the insertion position of the engaging bars 300.

Referring to FIG. 3, the connecting nut 200 has a hollow cross-section as a whole. When the connecting rod 300 is inserted into the connecting nut 200 in a corresponding manner, the latching groove 220 is recessed into the segment of the inner end surface of the connecting nut 200, And only when the shaft rotation position is changed at a predetermined angle in a state where the coupling rod 300 is inserted into the coupling nut 200, only the corner portions of the coupling rod 300 (311) is inserted into the locking engagement groove (220).
