[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figs. 1-3 The technical solution shown is a chip detection protective fixture. In order to solve the problem of inconvenient clamping during chip detection, the following is disclosed: a base 1 and a bidirectional threaded rod 2 provided inside the base 1, and an adjustment handle 3 provided on the right side of the bidirectional threaded rod 2. A movable plate 5 is provided on the surface of the bidirectional threaded rod 2, and a chip body 8 is provided on the surface of the base 1. The bidirectional threaded rod 2 is rotatably installed inside the base 1, and the two ends of the bidirectional threaded rod 2 have opposite thread directions. The surface of the bidirectional threaded rod 2 is threadedly connected to the movable plate 5. Holes are evenly opened on the surface of the adjustment handle 3, and a latch 4 is inserted into the adjustment handle 3 through the holes. The left end of the latch 4 is inserted into the right side of the base 1.

[0027] In use, place the chip body 8 on the surface of the base 1, and rotate the adjustment handle 3. When the adjustment handle 3 rotates, it drives the bidirectional threaded rod 2 to rotate. The rotation of the bidirectional threaded rod 2 can drive the movable plate 5 connected to its surface threadedly to move inward or outward simultaneously under the limit of the base 1. This allows for convenient clamping of the chip. At the same time, when the adjustment handle 3 is rotated, the adjustment handle 3 is locked by the latch 4 to fix it and prevent reverse rotation, thus achieving a convenient and stable clamping effect.

[0028] Example 2: Figs. 1-4The technical solution shown, based on Embodiment 1, discloses the following to address the issue of inadequate chip protection: a movable plate 6 is provided on the inner side of the movable plate 5, and protective and anti-damage mechanisms are provided on the left and right sides of the movable plate 6. These protective and anti-damage mechanisms include clamping plates 7, with the outer side of the clamping plates 7 positioned on the inner side of the movable plate 6. The movable plate 5 is I-shaped. The protective and anti-damage mechanisms include damping rods 10, with the middle end of the damping rods 10 penetrating and installed through the middle of the movable plate 5. Furthermore, a fixed fixture is fixedly installed on the inner side of the movable plate 5. The fixed plate 11 has a positioning rod 12 fixedly installed on its inner side. A slider 13 is installed through the surface of the positioning rod 12. An adjusting rod 14 is rotatably installed on the inner side of the slider 13.

The front and rear ends of the buffer spring 15 are set between the fixed plate 11 and the slider 13. The clamping plate 7 is right-angled. An anti-slip pad 9 is fixedly installed on the inner side of the clamping plate 7. The clamping plate 7 is correspondingly set with the chip body 8.

[0029] When the chip body 8 is clamped by the movable plate 5, the inner movable plate 6 and clamping plate 7 move inward to clamp the chip body 8. When clamping the chip body 8, the right-angled clamping plate 7 can clamp the four corners of the chip body 8, so that the force points are at the four corners, avoiding excessive pressure on the edges and damaging the chip. The anti-slip pad 9 can improve friction and prevent it from falling. At the same time, when the movable plate 6 and clamping plate 7 are clamping, the adjusting rod 14 is subjected to reverse pressure. Due to the rotational connection at both ends of the adjusting rod 14, the slider 13 can be rotated to slide along the positioning rod 12 on the inner side of the fixed plate 11. The buffer spring 15 provides buffering. The damping rod 10 can prevent the buffer spring 15 from vibrating back and forth, achieving the effect of buffering and shock absorption, avoiding excessive pressure and damaging the chip body 8, and further protecting the chip body 8 from easy damage during testing.

The output end of the air jet 18 is aligned with the surface of the chip body 8. The elastic airbag 16 and the movable plate 5 form a pressing structure. A one-way air inlet 19 is installed through the front end of the elastic airbag 16, and a one-way valve is provided inside the one-way air inlet 19.

[0031] When the movable plate 5 moves inward, the bottom rear end of the movable plate 5 extrudes the elastic air bag 16, the elastic air bag 16 is extruded to deliver the internal air to the air jet 18 through the air guide pipe 17, the air jet 18 blows the surface of the chip body 8, so that the blowing and impurity removing can be realized, and the dust and impurities on the surface of the chip body 8 can be avoided to affect the accuracy of detection, on the contrary, when the movable plate 5 stops extruding the elastic air bag 16, the elastic air bag 16 is reset through the elastic force of the elastic air bag 16, and the internal one-way valve of the one-way air inlet 19 is used for air intake circulation.
