In order to prevent rebound or loosening of the target product, the pressing member 330 cooperates with the first side of the molding plate 320 to form a first product limiting structure, so that the target product can be limited and fixed.

Referring to fig. 1 and 7, when a test is required, the quick-change fixture 300 preloaded with a target product is installed in the fixture positioning groove 101 of the base 100, and during the installation process, the quick-change fixture 300 and the base 100 are positioned by the second positioning portion 312 and the first positioning portion 102, so that the convenience and accuracy of installation are improved, and the test point of the target product is located at or near the expected position. when the quick-change fixture 300 is mounted in the fixture positioning groove 101, the fool-proof slider 340 of the quick-change fixture 300 can be partially inserted into the first avoidance space 103 of the base 100, and the fool-proof slider 340 is located at a first working position, where the fool-proof slider 340 is located on a movement path of the probe flip 200, and the fool-proof slider 340 interferes with a fool-proof mating portion (shown as a mark P1 in fig. 2) of the probe flip 200, so that the probe flip 200 cannot be covered, and abnormal contact (i.e., a contact position is not a predetermined test point) between the probe module 240 and the quick-change fixture 300 is prevented, thereby protecting the probe module 240, wherein one side edge of the cover plate 210 can be used as a fool-proof mating portion, i.e., the fool-proof slider 340 can interfere with an edge of the cover plate 210 in the first working position, or one side edge of the cover plate 210 is provided with a fool-proof protrusion (not shown) serving as a fool-proof mating portion, and the fool-proof slider 340 can interfere with the fool-proof protrusion. next, the fool-proof slider 340 is shifted to move the fool-proof slider 340 along the guiding hole 311, and the fool-proof slider 340 is switched from the first working position to the second working position (refer to fig. 2), at this time, the fool-proof slider 340 is away from the fool-proof matching portion of the probe flip 200, and the fool-proof slider 340 can be clamped with the clamping flange 104 of the base 100, so that the quick-change fixture 300 is fixed on the base 100, and damage or poor testing of the probe module 240 caused by displacement of the quick-change fixture 300 due to misoperation in the testing process is avoided. In addition, the fool-proof slider 340 can also cooperate with the second side of the shaping plate 320 to form a second product limiting structure, thereby limiting and shaping the target product. Next, referring to fig. 2 and 3, the probe flip 200 is covered on the fixture positioning slot 101, in the covering process, the positioning guide hole 321 performs positioning guide on the positioning guide post 231, so that the positioning guide post 231 drives the floating plate 220 to perform fine position adjustment, so that the position of the probe module 240 can be well adapted to the position of the quick-change fixture 300, and the alignment of the probe module 240 and the test point of the target product is accurate, and the limit lock structure 110 on the base 100 is matched and fixed with the probe flip 200, so that the probe flip 200 is prevented from displacing in the testing process, good contact between the probe and the test point can be maintained, and the reliability of the test is improved. it should be noted that, the fool-proof slider 340 can cooperate with the probe flip 200 to prevent fool, and cooperate with the clamping flange 104 of the base 100 to realize locking of the quick-change fixture 300, and cooperate with the second side of the shaping plate 320 to compress the target product, so that the structure is simple, but the functions are various, and the miniaturized design is facilitated.

In the test, it was found that a redundant gap is formed between the first positioning portion 102 and the second positioning portion 312, for example, in the case that the first positioning portion 102 is a protrusion, and the second positioning portion 312 is a recess, the outer diameter of the protrusion is smaller than the inner diameter of the recess, so that a redundant gap, that is, a loose space, is left between the outer wall of the protrusion and the inner wall of the recess, so that the recess and the protrusion are sleeved. However, in an accidental situation, the redundant gap between the first positioning portion 102 and the second positioning portion 312 may cause misalignment between the probe and the test point, so that the first elastic pressing member 120 is configured to be able to abut against the quick-change fixture 300, thereby pushing the quick-change fixture 300 to a predetermined position, reducing the displacement space of the quick-change fixture 300, and further improving the alignment accuracy of the probe and the test point. In the present embodiment, the first side and the second side of the clip positioning groove 101 are adjacent two sides, and of course, in some application examples, the first side and the second side of the clip positioning groove 101 may be opposite two sides.

The first fitting structure 121 may be a housing mounted on the base 100, or the first fitting structure 121 may be a structure machined on the base 100. When the quick-change clamp 300 is mounted in the clamp positioning groove 101, the quick-change clamp 300 abuts against the first pressing block 122, so that the first pressing block 122 compresses the second elastic member 123, and the second elastic member 123 provides continuous elastic force for the first pressing block 122, so that the first pressing block 122 keeps pressing against the quick-change clamp 300, and the quick-change clamp 300 is fixed at a predetermined position. The second elastic member 123 adopts a spring, and a guiding structure such as a rounded corner structure or an oblique angle structure is disposed at an end of the first pressing block 122, so that the quick-change fixture 300 abuts against the first pressing block 122 when being placed into the fixture positioning groove 101.

Wherein the fourth elastic member 353 employs a spring, and the end of the second pressing block 352 is provided with a guide structure such as a rounded or beveled structure so as to facilitate insertion of the target product into the gap between the second pressing block 352 and the setting plate 320.
