[0035] A hollow portion 21 is provided at the bottom of the detection seat 2 and can be movably mounted on the probe seat 11. Plunger springs 22 are provided on both sides of the hollow portion 21 so that after the hollow portion 21 is mounted on the probe seat 11, the plunger springs 22 clamp the probe seat 11. A through hole 23 corresponding to the position of each test probe 12 and through which the probe can penetrate is provided in the hollow portion 21.

[0036] The top of the test base 2 is fixedly mounted with an adapter plate 4, which is provided with a metal pad corresponding to each through hole 23 and can be contacted by the test probe 12. A positioning piece 41 is installed on the adapter plate 4, and the positioning piece 41 is provided with a circuit board placement portion 42. The adapter plate 4 is installed with a first B2B located in the circuit board placement portion 42. A functional circuit board 43 is placed in the circuit board placement portion 42, and the functional circuit board 43 is installed with a second B2B that is buckled with the first B2B, so that the adapter plate 4 is connected to the functional circuit board 43 by electrical signals. The adapter plate 4 is also provided with a wiring board connected to the external device signal.

[0037] Guide blocks 5 are installed on both sides of the detection seat 2. The guide blocks 5 are provided with slide slot holes 51.
