At this time, the first spring 406 is squeezed by force, and the L-shaped rack 404 moves to drive the spur gear 403 to rotate clockwise. The rotation of the spur gear 403 drives the rotating rod 401 to rotate. The rotation of the rotating rod 401 drives the clamping block 402 to rotate. Since the clamping block 402 is L-shaped, the clamping block 402 rotates and contacts the top of the terminal. The terminal is clamped and fixed by the rotating clamping block 402.

[0051] The L-shaped rack 404 moves downward and drives the fixed block 5 to move at the same time. The fixed block 5 moves and contacts the clamping block 501. The fixed block 5 continues to move and squeezes the clamping block 501 to move horizontally. At this time, the second spring 5021 is squeezed. When the clamping slot at one end of the fixed block 5 and the clamping block 501 are at the same horizontal height, the second spring 5021 returns to its original state and drives the clamping block 501 to reset and move. The clamping block 501 resets and moves and is fixed in the clamping slot. At this time, the L-shaped rack 404 is locked.

[0052] Secondly, when it is necessary to disassemble the terminal, the user pulls the pull plate 503, the pull plate 503 moves to drive the pull rod 502 to move, the pull rod 502 moves to drive the block 501 to move, the block 501 moves and separates from the slot, and at the same time the first spring 406 returns to its original state and drives the sliding block 405 to move upward, the sliding block 405 moves to drive the terminal to move upward, the sliding block 405 moves and drives the L-shaped rack 404 to move, the L-shaped rack 404 moves and drives the clamping block 402 to rotate through mechanical transmission, at this time the terminal is initially separated from the inside of the terminal holder 3, and then the user releases the pull plate 503, the second spring 5021 returns to its original state and drives the block 501 to reset and move, and the user can subsequently disassemble the terminal;

[0053] Finally, the sliding block 405 moves vertically downward under the squeezing force of the terminal, and the sliding block 405 moves and drives the clamping block 402 to rotate through mechanical transmission. The clamping block 402 rotates and contacts the top of the terminal, and the terminal is clamped and fixed by the clamping block 402 to avoid poor contact between the terminal and the terminal holder 3 during testing, thereby ensuring the stability of the terminal signal during testing. At the same time, through the setting of the first spring 406, it is convenient to provide the terminal with a driving force for disassembly, compared with the traditional disassembly method by hard disassembly, the convenience of disassembling the terminal holder 3 and the terminal is improved.
