うにしたものである。The present invention relates to a base, left and right parts of the base which are slidably provided in the front-rear direction, left and right extrusion rods facing the front-rear direction, and an intermediate part of the base which is slidably provided in the front-rear direction. The left and right slides are slidably fitted in open / closed rods facing the front-rear direction and the bottomed holes drilled from the rear ends of the extrusion rods, and are spring-biased rearward. With a rod
A connecting plate that connects the rear end of the opening / closing rod and the left and right sliding rods and can be moved back and forth by an appropriate driving device, and an extruding rod provided at the rear end of each extruding rod. When it reaches the front limit position, it comes into contact with the base to stop the pushing rod, a mounting plate fixed across the front ends of the left and right pushing rods, and the mounting plate. Fixed pair of left and right fixed fingers, a pair of left and right movable fingers that are pivotally attached to the mounting plate so as to face each fixed finger, and are spring-biased in a direction toward each other, and each fixed The fingers, the workpiece support piece and the workpiece sandwiching piece that are provided at the tips of the movable fingers that face each other, and the workpiece sandwiching piece that face each other, and the slope that is provided on the facing surface of each movable finger so that the rear is closer to the facing side With the inclined surface At the front end of the opening / closing rod, a horizontal roller provided so as to abut the both inclined surfaces is provided, and when the opening / closing rod is moved forward or backward by a certain amount or more with respect to the pushing rod, the inclined surface and the roller Each movable finger can be closed and opened with respect to the fixed finger.
