[0030] After the carrier plate 2 and the fixture 4 are installed, the product to be tested is placed on the top of the fixture 4, and then the carrier plate 2 causes the pressure rod 21 to descend, and the pressure rod 21 presses the product on the top of the fixture 4, and the product can be tested.

[0031] This embodiment realizes the rapid line change of the test fixture 4 through simple operation steps and automatic docking structure. Compared with the traditional line change method, the present invention has high efficiency and simpler operation steps, which greatly shortens the production line change time. At the same time, the present invention can also make corresponding needle beds according to different actual needs, realize the reuse of test equipment, and has strong flexibility and practicality.

[0032] The quick line changing device of an automatic testing equipment described in this embodiment, the lower fixed seat includes a first fixed seat 31, a second fixed seat 32, a third fixed seat 33 and a fourth fixed seat 34; the two sides of the fixture 4 are respectively detachably connected to the first fixed seat 31 and the second fixed seat 32; the third fixed seat 33 and the fourth fixed seat 34 are both provided with a driving member 62; the output ends of the two driving members 62 are respectively connected to the two sides of the docking plate 6.
