When the movable block 24 is forced to move to one side, the movable block 24 will drive the slider 241 to slide along the inner cavity of the slide groove 211, thereby ensuring the stability of the slider 241 during movement and preventing it from being misplaced. The fixing plate 251 can well support the spring 25 to ensure the stability of the spring 25. Specific embodiment three

[0036] See also Figure 1 , 2 and 4. On the basis of specific embodiments one and two, the front end of the right side of the connecting seat 21 is movably connected to a clamping plate 221 through a rotating shaft, one end of the clamping plate 221 extends to the inner cavity of the disk 22 and is movably connected to the inner cavity of the disk 22; the front side of the top seat 14 is movably connected to a hook 142 through a rotating shaft, the front side of the placement seat 11 is fixedly connected to a hanging rod 112, the hook 142 is sleeved on the surface of the hanging rod 112, and is movably connected to the surface of the hanging rod 112; both sides of the bottom of the top seat 14 are fixedly connected to connecting blocks 141, and both sides of the top of the placement seat 11 are provided with connecting grooves 111, the bottom of the connecting block 141 extends to the inner cavity of the connecting groove 111, and is movably connected to the inner cavity of the connecting groove 111.

[0037] Specifically: by rotating the clamping plate 221, one end of the clamping plate 221 moves to one side around the axis of the rotating shaft to the inner cavity of the disc 22, thereby realizing the positioning of the disc 22, and by rotating the hook 142, the hook 142 gradually moves toward the hanging rod 112 around the axis of the rotating shaft until the hanging rod 112 is located in the inner cavity of the hook 142, thereby realizing the clamping positioning of the placement seat 11 and the top seat 14, and the top seat 14 is forced to move to one side around the axis of the rotating shaft to contact the placement seat 11, and at the same time, the top seat 14 drives the connecting block 141 to enter the inner cavity of the connecting groove 111, thereby limiting the connection between the top seat 14 and the placement seat 11.

[0038] The working principle of the utility model is as follows: first, the chip is placed inside the positioning groove 12 and located on the top of the substrate 13. The positioning groove 12 is adapted to the chip, and the chip can be limited. Then, the top seat 14 is pushed, and the top seat 14 is in contact and connected with the placement seat 11 around the axis of the rotating shaft. Then, by rotating the hook 142, the hook 142 gradually moves toward the hanging rod 112 around the axis of the rotating shaft until the hanging rod 112 is located in the inner cavity of the hook 142, completing the clamping of the placement seat 11 and the top seat 14, thereby realizing the positioning of the chip. Then, by rotating the threaded column 16, the threaded column 16 drives the pressing plate 15 downward to press the chip and the substrate 13, thereby facilitating the chip pressing test. After the pressing test is completed, the push rod 23 is driven to move to one side by pushing the disk 22, and the push rod 23 drives the movable block 24 and the spring 25 The movement to one side causes the spring 25 to stretch and deform, and the movable block 24 gradually moves to the bottom of the connecting rod 26, lifting the connecting rod 26, and rotating the card plate 221 at the same time. One end of the card plate 221 moves to one side around the axis of the rotating shaft to the inner cavity of the disk 22, thereby realizing the positioning of the disk 22 and preventing the disk 22 from moving on its own. After that, the upward movement of the connecting rod 26 can drive the substrate 13 and the chip to gradually separate from the inner cavity of the positioning groove 12, thereby realizing the removal of the chip, which is not only fast and convenient, but also will not cause the chip to be worn. After the chip is taken out, the card plate 221 is rotated to separate from the inner cavity of the disk 22 to release the positioning of the disk 22. Finally, the reset elastic force of the spring 25 drives the movable block 24 to reset, and then the connecting rod 26 will naturally descend to drive the substrate 13 to re-enter the interior of the positioning groove 12, which is convenient for later reuse.
