[0043] When the chip is on the test unit, the operator removes the force pressing the upper cover 12, and the fourth spring restores the elastic deformation force to drive the upper cover 12 to move upward, and the moving upper cover 12 drives the pressing block 37 to move toward the test unit, and the pressing block 37 drives the synchronization block 14 to move downward.

When the upper cover 12 needs to be restored to its original position, the operator presses the unlocking block 73, and the unlocking block 73 pushes the locking block 71 to move, so that the locking block 71 is no longer engaged with the locking groove 121 and re-enters the third groove, and the force of the fourth spring to restore the elastic deformation will drive the upper cover 12 to return to its original position; when the unlocking block 73 moves, the slider 75 on the unlocking block 73 slides in the slide groove, and when the locking block 71 is completely located in the third groove, the third spring 74 is in a stretched state; when the upper cover 12 moves upward and the locking block 71 is misaligned with the locking groove 121, the force of the third spring 74 to restore the elastic deformation will drive the slider 75 to move, and the slider 75 drives the locking block 71 to return to its original position.

[0050] When the locking block 71 moves and engages with the locking groove 121, the first rack 821 on the locking block 71 drives the first gear 823 to rotate, the first gear 823 drives the first adjustment shaft 822 to rotate, the first adjustment shaft 822 drives the third gear 826 to rotate, the third gear 826 drives the second gear 825 to rotate under the action of multiple transmission gears 827, the second gear 825 drives the second rack 824 to move, and the second rack 824 will adjust the block 81 to move upward, so that the adjustment block 81 passes through the second through hole on the synchronization block 14, and then the operator places the chip on the test unit. When the unlocking block 73 pushes the locking block 71 to move so that the locking block 71 is completely located in the third groove, the adjustment block 81 will return to its original position.

[0051] refer to Figure 6 and Figure 8 An eighth groove is formed on the base 11, and a second cavity connecting the eighth groove and the seventh groove is formed on the base 11.

[0052] The base 11 is provided with a limiting mechanism 9, which includes a limiting block 91 slidably connected in the second cavity, and a limiting groove engaged with the limiting block 91 is provided on the adjusting block 81. The base 11 is provided with a second adjusting assembly 92, which includes a support block 921 slidably connected in the eighth groove, and the upper cover 12 can resist the support block 921; the support block 921 is connected with a fifth spring 922, and the end of the fifth spring 922 away from the support block 921 is connected to the base 11; the support block 921 is fixedly connected with a third rack 923, and the base 11 is rotatably connected with a second adjusting shaft 924 located in the second cavity, one end of the second adjusting shaft 924 is keyed to a fourth gear 925 meshing with the third rack 923, and one end of the second adjusting shaft 924 away from the fourth gear 925 is keyed to a fifth gear 926, and the limiting block 91 is fixedly connected with a fourth rack 927 meshing with the fifth gear 926.

[0053] When the upper cover 12 is pressed, the upper cover 12 will contact the support block 921 and push the support block 921 to move, and the fifth spring 922 is compressed; the third rack 923 on the support block 921 drives the fourth gear 925 to rotate, the fourth gear 925 drives the second adjusting shaft 924 to rotate, the second adjusting shaft 924 drives the fifth gear 926 to rotate, the fifth gear 926 drives the fourth rack 927 to move, and the fourth rack 927 drives the limiting block 91 to move, so that the limiting block 91 is no longer engaged with the limiting groove on the adjusting block 81; at this time, the locking block 71 is not aligned with the locking groove 121 on the upper cover 12.

[0054] Then continue to press the upper cover 12. When the locking block 71 is aligned with the locking groove 121 on the upper cover 12, the third spring 74 will drive the locking block 71 to engage with the locking groove 121. At the same time, the locking block 71 drives the adjusting block 81 to move upward, so that the end of the adjusting block 81 with the test unit passes through the second through hole on the synchronization block 14. The operator then places the chip on the test unit.

[0055] Then the operator presses the unlocking block 73, and the unlocking block 73 pushes the locking block 71 to move, so that the locking block 71 completely enters the third groove and is no longer engaged with the locking groove 121; at this time, the locking block 71 drives the adjustment block 81 to return to its original position. When the locking block 71 is no longer engaged with the locking groove 121, the fifth spring 922 and the fourth spring will restore elastic deformation. When the fifth spring 922 restores elastic deformation, the support block 921 will return to its original position. When the support block 921 moves, it will drive the limiting block 91 to move, so that the limiting block 91 is engaged with the adjustment groove on the adjustment block 81; after the fifth spring 922 has completely restored its elastic deformation, the fourth spring has not completely restored its elastic deformation; then the force of the fourth spring to completely restore its elastic deformation will continue to drive the upper cover 12 to move, so that the upper cover 12 returns to its original position, that is, after the limiting block 91 is engaged with the limiting groove on the adjustment block 81, the upper cover 12 continues to move.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
