[0051] Operation process: The entire device has two usage modes: 1. Buffer mode: The operator slides the arc block 104g downward, and at this time the operator activates the track strip 200a, causing the track strip 200a to move. Because of the guidance of the shape of the groove surrounded by the two inclined planes 402, the block 104f and the arc block 104g, the track strip 200a is close to the second gear 104d, and then the support member outside the track strip 200a drives the second gear 104d to rotate, and then the steering rod 106 rotates, thereby driving the rotation of the receiving block 101, causing the clamped chip to rotate. ; 2. Fixed connection mode: The operator moves the arc block 104g upward so that the supplementary block blocks the groove surrounded by the two inclined surfaces 402 block 104f and the arc block 104g, and the two remaining arc channels are connected to the guide rail 108. At this time, the operator starts the movement of the track strip 200a. The movement of the track strip 200a will drive the rotation of the third gear 304 through the external support member, thereby driving the rack 303 on the side wall of the telescopic slide rod 301 to move, and the movement of the telescopic slide rod 301 will pull the steering rod 106 back and forth for adjustment in the longitudinal direction.
