[0002] The chip needs to be tested before use, and the existing chip testing method is to test it through a chip test seat. The existing chip test seat is to place the chip in the chip placement position of the test seat, and cover the chip placement position with a pressure cover. The chip is clamped between the bottom seat and the upper cover, so that the chip pins can be fully in contact with the ejector pins, and the chip can be controlled to complete a specific function. However, one end of the cover is generally rotatably set on one side of the chip test seat body. This process requires a person to manually close the cover. Since the cover is set on one side of the chip test seat body, there is a process of bevel pressure covering. The operation process is relatively long and the operation is complicated.

[0028] Working principle: When using the test socket of the present technical solution, first press down the upper cover 2. The upper cover 2 can drive the vertical rod 7 to move downward during the downward movement. The vertical rod 7 can drive the hook 3 to rotate during the downward movement, so that the hook 3 is rotated and lifted upward from the horizontal state. At this time, the reserved gap between the two hooks 3 is enough to place the chip. When the upper cover 2 is pressed down for the first time, the upper cover 2 can drive the top block 4 to slide inside the protective cover 5 during the downward pressing process. When the upper cover 2 is pressed down for the first time to cause the hook 3 to rotate and lift upward from the horizontal state, the top block 4 slides inside the protective cover 5 until it contacts the top of the larger diameter end of the connecting protrusion 62.

[0029] When the hook 3 is lifted upward, the chip is placed in the test position of the body 1, and then the upper cover 2 is continuously pressed downward. During the downward movement of the upper cover 2, the top block 4 can be driven to continue to move downward. During the downward movement, the top block 4 can squeeze the connecting protrusion 62 to move downward. During the downward movement, the connecting protrusion 62 can compress the spring 63. Then, the upper cover 2 is released. At this time, the connecting protrusion 62 and the top block 4 can be pushed upward under the action of the restoring force of the spring 63, so that the upper cover 2 can be moved upward and reset. During the upward movement of the upper cover 2, the vertical rod 7 can be driven upward, so that the hook 3 can be driven to rotate to a horizontal state. After the hook 3 rotates to a horizontal state, it can press the chip, and then the chip is tested.

[0030] In summary, the utility model can first lift the hook 3 upward by pressing the upper cover 2 downward for the first time, then put the chip on the body 1, and then press the upper cover 2 downward again to compress the spring 63. After pressing the upper cover 2 downward again and then releasing the upper cover 2, the upper cover 2 can be reset under the reset action of the spring 63, so that the hook 3 presses the chip.
