[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-2 The utility model provides a technical solution: a structure in which a flying probe for first-piece inspection can be replaced quickly and accurately, comprising a mounting seat 1, a guide groove 2 fixedly opened at the center of the mounting seat 1, a crown spring 3 fixedly connected to the inside of the guide groove 2, and a number of crown springs 3, a flying probe body 4 inserted into the inside of the mounting seat 1, and the flying probe body 4 inserted into the inside of the crown spring 3.

[0016] In this embodiment, by inserting the flying needle body 4 into the inside of the mounting seat 1 and cooperating with the grip of the crown spring 3, automatic concentricity and no runout error can be guaranteed. By adopting the specifications of the crown spring 3 with suitable force, the flying needle body 4 can be effectively guaranteed to be stable and not fall off. The flying needle body 4 can also be directly plugged in and replaced, and the repetition accuracy can be guaranteed each time. This design method can directly plug in and replace the flying needle body 4, and can be repeatedly replaced and used many times. It is simple to process and easy to replace.

[0017] Specifically, a fixing device 5 is fixedly connected to the back of the mounting seat 1 , and the fixing device 5 includes a fixing block 6 , a threaded rod 7 , a rotating block 8 , a sliding block 9 and a clamping plate 10 .

[0018] In this embodiment, the fixing device 5 can be used for clamping and fixing. This design adopts a clamping and fixing method for fixing. The fixing method is diverse, can adapt to various places, has a wide range of applications, and has a good fixing effect.

[0019] Specifically, sliding grooves 12 are fixedly provided on both sides of the surface of the fixed block 6, and sliders 9 are slidably connected inside the sliding grooves 12 on both sides. The upper end of the slider 9 is fixedly connected to a splint 10, and anti-slip teeth 11 are fixedly provided on the inner side of the splint 10.

[0020] In this embodiment, the sliding clamping plate 10 can be clamped and fixed, so that the fixing effect of the mounting seat 1 is good. The anti-slip teeth 11 opened inside the clamping plate 10 can avoid sliding, so that the clamping and fixing effect of the clamping plate 10 is better.

[0021] Specifically, the interior of the slide groove 12 is rotatably connected to a threaded rod 7 , the threaded rod 7 is threadedly sleeved with the slider 9 , the threads at both ends of the threaded rod 7 are opposite, and one end of the threaded rod 7 is fixedly connected to a rotating block 8 .
