<p>PURPOSE:To improve the using convenience by constituting the arm of plural members which can be fitted to female and male dies, so that the length of a part related to its fitting can be adjusted. CONSTITUTION:Each arm 6 and a tip arm 6A are constituted by combining two bodies of a male die member 61 and a female die member 62. Accordingly, the key part 61C of the male die member 61 is positioned so as to match the positioning group 62C of a female die member socket part 62A, and by inserting the end part of the male die member 61 into the socket part 62A, an engaging member 61A can be inserted into an arbitrary position, while deforming it, and by engaging the detaining member 61A to an arbitrary detaining groove 62B, a part between both of them can be held in a fixed state. Also, when it is necessary to change the length of the arm 6, the male die member 61 is pushed in or drawn back against the spring force of the engaging member 61A, so that the engaging member 61A is engaged to other engaging groove 62B.</p> |
