[0029] The specific use of the present utility model is as follows. First, after clamping an article, by controlling the first cylinder 22, its first telescopic rod is telescoped, so as to drive the moving plate 23 to slide in the slot 211, realizing the movement of the manipulator 3 in the X-axis direction. By controlling the second cylinder 243, its second telescopic rod is telescoped, so as to drive the clamping plate 241 and the sliding plate 24 to slide in the sliding slot of the fixing plate 232, realizing the movement of the manipulator 3 in the Y-axis direction. By controlling the third cylinder 261, its third telescopic rod is telescoped, so as to drive the sliding rod 26 and the plate 27 to move up and down, realizing the movement of the manipulator 3 in the Z-axis direction. When the manipulator 3 moves to the position where the article needs to be grasped, the manipulator 3 is operated to clamp. After the clamped article reaches the target position, by controlling the manipulator 3 to release the clamp, the article is placed in place. When it is necessary to replace the manipulator 3 of different sizes or replace the damaged manipulator 3, first loosen the positioning rod 55 on the positioning plate 54 to make it move in the hole of the moving rod 53. Since one end of the moving rod 53 is fixed to the clamping arc plate 51, during the movement process, the clamping arc plate 51 will also move in the directions on both sides of the groove body, so that the clamping arc plate 51 releases the fixation of the fixed rod 28. Then, the fixed rod 28 on the manipulator 3 is removed from the opening, and the new manipulator 3 is slidably installed into the opening at the bottom center of the plate 27 through the top of the fixed rod 28 and ensured to be stable. Then, by moving the moving rod 53, the bolt 52 on the clamping arc plate 51 is stuck in the groove 281 of the fixed rod 28. Align the other end of the moving rod 53 with the small hole on the positioning plate 54, reinstall the positioning rod 55, and ensure the position of the moving rod 53 is fixed by tightening and locking.
