[0029] This utility model, by setting a first groove 8, a first spring 9, and an arc plate 10, can clamp and fix the probe card during use through the first spring 9 and the arc plate 10, which can prevent the probe card from shifting or being impacted within the protective device, making it more convenient for staff to use.

[0030] In a preferred embodiment, a through groove 18 is provided at the bottom of the rectangular block 1. A long rod 19 is slidably connected to the inner wall of the through groove 18. The long rod 19 extends into the interior of the first groove 8 and passes through the placement plate 14. A bearing plate 15 is fixedly installed at one end of the long rod 19, and a circular block 21 is fixedly installed at the other end of the long rod 19. A second spring 20 is sleeved on the outer wall of the long rod 19. One end of the second spring 20 is fixedly connected to the bottom of the placement plate 14, and the other end of the second spring 20 is fixedly connected to the inner wall of the circular block 21.

[0031] By incorporating a through groove 18, a long rod 19, a support plate 15, a circular block 21, and a second spring 20, this design facilitates the removal of the probe card from the first groove 8 during use. This design makes it easier for staff to place and retrieve the probe card, making it more convenient to use.

[0032] In a preferred embodiment, a rotating block 22 is rotatably connected to the outer wall of the rectangular block 1 at the position corresponding to the circular block 21.

A limit block 23 is fixedly installed at the bottom of the rectangular block 1 at the position corresponding to the rotating block 22.

[0033] By setting the rotating block 22, this design can limit the circular block 21 during use. By setting the limiting block 23, this design can limit the rotating block 22 during use, preventing the rotating block 22 from rotating too far. By setting the rubber plate 16, this design can buffer the probe card during use.

[0034] As a preferred embodiment, rubber pads 12 are fixedly installed on the opposite surfaces of the two arc-shaped plates 10, and guide plates 11 are fixedly installed on the upper surface of the arc-shaped plates 10.

[0035] By setting the rubber pad 12, this design can buffer the probe card during use, making it more convenient to use. By setting the guide plate 11, this design makes it easier for staff to place the probe card between the two curved plates 10 during use.

[0036] As a preferred embodiment, a circular groove 17 is provided on the upper end face of the rectangular block 1 at the position corresponding to the first groove 8, a sealing ring 27 is fixedly installed on the bottom of the cover plate 2 at the position corresponding to the circular groove 17, and a foam board 26 is fixedly installed on the inner wall of the second groove 25.

[0037] By setting the circular groove 17, sealing ring 27, and foam board 26, this design can increase the sealing between the rectangular block 1 and the cover plate 2 during use, thereby preventing dust from entering the first groove 8. The foam board 26 can also buffer the probe card.

[0038] In a preferred embodiment, a fixing block 3 is fixedly installed on the outer wall of the rectangular block 1, and an L-shaped fastener 4 is rotatably connected to the inner wall of the fixing block 3. The inner wall of the L-shaped fastener 4 abuts against the outer wall of the cover plate 2.

[0039] By setting the fixing block 3 and the L-shaped fastener 4, this design can fix the rectangular block 1 and the cover plate 2 during use, making it more convenient to use.

[0040] As a preferred embodiment, a limiting frame 5 is fixedly installed at the bottom of the rectangular block 1, and a placement groove 6 is provided at the position corresponding to the L-shaped buckle 4 of the limiting frame 5. An L-shaped card block 7 is fixedly installed symmetrically on the upper surface of the cover plate 2 at the position corresponding to the limiting frame 5.

[0041] By setting the limiting frame 5, the placement groove 6, and the L-shaped locking block 7, this design can fix two protective devices when there are many protective devices during use, preventing them from colliding during transportation and causing damage to the outer wall of the protective devices.

[0042] The principle and process of this utility model:

[0043] In use, the probe card protection device of this utility model involves rotating the L-shaped buckle 4 to separate it from the upper surface of the cover plate 2, then opening the rectangular block 1 and the cover plate 2, and then rotating the rotating block 22 to separate it from the circular block 21. At this time, the second spring 20 retracts, causing the long rod 19 to push the bearing plate 15 upwards. The probe card is then pushed out from between the two arc-shaped plates 10 through the bearing plate 15, making it easier for staff to pick up the probe card. This design makes it more convenient for staff to use.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
