Referring to FIG. 1-4, the pick-and-place jig 10 of the present invention can be applied to the protective upper cover 41 of the central processing unit receiving slot 40 on the pick-and-place circuit board 30, and the positioning legs 17, 18, 19, and 20 are placed. Holes 31, 32, 33, 34 on the circuit board 30 (in the present embodiment, the holes 31, 32, 33, 34 are positioning holes of the central processor cooling fan), and then the handles 12, 13 are pressed down. The movable support base 11 connected to the shifting handles 12, 13 slides down along the positioning legs 17, 18, 19, 20. Since the pick-and-place unit 14 is also fixed to the movable support base 11, the pick-and-place unit 14 is also Moving downward, when the clamping members 141, 142 of the pick-and-place unit 14 are moved to the proper position (the position at which the upper cover 41 can be held), the clamping members 141, 142 are pressed inward (as shown in Fig. 2). At this time, the clamping members 141, 142 can take the protective upper cover 41. Since the elastic members 21 are connected between the clamping members 141, 142, the clamping members 141, 142 can be held and protected when the clamping members 141, 142 are loosened. Upper cover 41. At this time, the user no longer applies force to the shifting handles 12, 13. Since the elastic member 183 is disposed in the sliding sleeve 184, the movable supporting base 11 is moved upward to the original position, so that the protective upper cover 41 can be evenly The central processing unit accommodates the slot 40 for removal without damaging the pins.
