When the engaging portions 6 and 7 rotate until they come into contact with the arcuate surfaces 10a and 11a of the guiding portions 10 and 11, the engaging portions 6 and
7 is elastically deformed to the state shown in FIGS. 4 and 5. That is, since the arcuate surfaces 10a and 11a are flush with the peripheral surfaces of the engagement holes 1a and 2a, in the state shown in FIGS. 4 and 5, the maximum distance between the engagement portions 6 and 7 is the mounting member 1, The diameter is the same as that of the two engaging holes 1a and 2a. That is, the engaging portions 6 and 7
Since the engagement is released (see FIG. 5), the coupling tool 3 can be pulled out from the attachment members 1 and 2. Therefore, the connection between the attachment members 1 and 2 is released (see FIG. 6).
