PURPOSE:To grasp round and angular work and to detect a hole in the plate by providing round work grasping faces at the facing surfaces of a pair of slide arms movable in symmetrical directions while an arched face on the back and a slide pin at the tip of arm. CONSTITUTION:Upon driving of an air motor 7, a threaded shaft 3 will rotate to move the slide arms 9a, 9b in symmetrical directions thus to grasp a round work or an angular work. A ring work is grasped by the back faces of the arms 9a, 9b. A holed work 24 is grasped by inserting pins 11a, 11b into two holes 24a, 24b then moving the arms 9a, 9b. In case of holed plate 25, the slide 11a is contacted against the plate 24 to push the arm 9a until a sensor 13 will turn on then the arm 9a is moved to the right and left to locate the hole 26. Upon insertion into the hole 26, the sensor 13 is turned off to detect the hole 26.
