Detailed Description

As shown in fig. 1 and 2, the chip extractor comprises a clamping plate 1 for clamping a chip 6, wherein the clamping plate 1 is in a transverse C shape, and the thickness of a clamping jaw at the bottom of the clamping plate 1 is slightly smaller than the distance from the chip 6 to be tested to a test board 7. The outside cover of splint 1 is equipped with sliding connection's guide bracket 2, and the outside cover of guide bracket 2 is equipped with sliding connection's push pedal 3, and splint 1, guide bracket 2 and push pedal 3 pass through connecting rod 4 to be connected, and splint 1 and push pedal 3 inside wall, the lateral wall of relative guide bracket 2 slide perpendicularly along opposite direction under the effect of connecting rod 4.

Specifically, the inner side wall of the push plate 3 is provided with a first sliding groove 34, the corresponding position of the outer side wall of the guide support 2 is provided with a corresponding convex sliding strip 24, the inner side wall of the guide support 2 is provided with a second sliding groove 23, and the clamping plate 1 is arranged inside the second sliding groove 23 and slides up and down along the second sliding groove.

Specifically, a pair of opposite lugs 31 are respectively arranged on two outer side walls of the push plate 3, a first connecting hole 32 is formed by penetrating the lugs 31, a first movable groove 33 is formed between the lugs 31 in the height direction of the side wall of the push plate 3, the guide support 2 and the corresponding position of the clamping plate 1 are respectively provided with a second movable groove 22 and a third movable groove 12, the connecting positions of the guide support 2 and the clamping plate 3 corresponding to the connecting rod 4 are respectively provided with a second connecting hole 21 and a third connecting hole 11, meanwhile, the height of the first connecting hole 32 is larger than that of the second connecting hole 21, and the height of the second connecting hole 21 is larger than that of the third connecting hole 11.
