    • PURPOSE:To realize the automatization by providing a guidance plate for supporting a position being adjacent to a ball socket and moving upward and downward and to the right and the left. CONSTITUTION:A lead ball socket 4 is fitted into a bench body 3 having a glass window 2 on a lead wall 1 and a tong 5 passes through the lead ball so as to be slidable. A square frame-like supporting frame 8 is attached adjacently to the lead ball 4 on a fitting base 9. On a guidance plate 13 (not shown in the figure) being movable upward and downward and to the right and the belt (upward and downward and in the direction vertical to the drawing, in the drawing) in the supporting frame 8, a swivel bearing 14 is provided, and the tong 5 is supported so as to be movable forward and backward (to the right and the left in the figure) by a driving mechanism 15 fixed and provided on the swivel bearing 14. The guidance plate 13 is balance-supported by the supporting frame 8 with a constant-output spring 31 (not shown in the figure), and also, driven upward and downward and to the right and the left by a ball screw mechanism. Since the guidance plate 13 is adjacent to the lead ball 4, a claw tip 6 of the tong 5 can be moved considerably by a slight movement. Since a projecting force spring 31 is provided, the device can be operated with high accuracy without being influenced by its dead weight.
