Patent abstract
A plurality of workpiece holders 52 are attached on a slide plate 71 on a bar 14 and connected to a movable plate 72 by a plate connecting portion 73. The plate connecting portion 73 includes an engaging portion 731 that is provided on the movable plate 72 and an engaged portion 732 that is provided on the slide plate 71 and engaged with the engaging portion 731. By moving a fixed bar 141 downward relative to a movable bar 142, the movable bar 142 is detached and the engagement of the engaging portion 731 with the engaged portion 732 is released. Since both of the movable bar 142 and the slide plate 71 can be detached by a single downward movement of the fixed bar 141, no actuator is required, thereby simplifying the structure.
