PURPOSE:To release connection by only supplying or removing pressured fluid by so structuring the titled device that a cylinder moves in protruding direction and a piston rod moves in retracting direction when pressure fluid is supplied to the cylinder, and providing a fitting hole for cylinder on the end face of the change side of a feed bar and providing a T-groove that engages with a die. CONSTITUTION:When pressured fluid is supplied from a supply port 17, a piston 11 is pushed to the right in pressing a spring 13, and a rear piston rod 11b hits against the fixed side of a bar 8. A die 16 fixed to the front piston rod 11a hits against a T-groove 18 of the change side of a feed bar 9. As the rear piston rod 11b hits to fix the piston 11, the large diameter part of the cylinder 10 stops when it hits against a retainer 12. At this time, the end part of the cylinder 10 fits in a fitting hole 19. Thus, feed bars 8 and 9 are connected. When pressure fluid is discharged, the cylinder 10 is moved to the right and the piston 11 is moved to the left by force of springs 13 and 14, and the connection of feed bars 8 and 9 is released. |
