PURPOSE:To facilitate fastening and demounting of a work independently of the distribution of the dimension of thickness of the work by pressing a swing tool through the contact between the conical top edges of three slidable pins and a spherical body and closely attaching a fastening metal onto the work. CONSTITUTION:When a work 1 is mounted, a pressing tool 11 is loosened to contract a slidable pin 10 inwardly, and a fastening metal 18 is allowed to turn leftward around a supporting pin 17 and stop by an annular member 20. The inside diameter 3 of the work 1 is inserted into a faucet 5, and the member 20 is turned leftward, and also the fastening metal 18 is turned leftward, and the falling-off of the work 1 is prevented. When the pressing tool 11 is turned rightward, the pressing tool 11 is advanced by an inside screw 12 and presses a spherical body 13 and pushing-spreads the slidable pin 10 outward to press a swing tool 16, and therefore, the turn around an installation pin 14 is formed, and the fastening metal 18 closely attaches the edge surface 2 onto a jig independently of the distribution of the dimension C of thickness of the work 1. |
