In this embodiment, there are four

station areas

220, and 2, 0, 1 and 2 arc-shaped protrusions 221 are respectively distributed in the station areas 220 from front to back.

A driving component for driving the test board 22 to move back and forth is arranged between the two supporting blocks 11. The driving assembly comprises a screw rod 14 arranged in the front-back direction, a sliding block 15 arranged on the screw rod 14 and a motor 16 used for driving the screw rod 14 to rotate and driving the sliding block 15 to move back and forth, and the motor 16 is connected with the controller. The bottom of the testing board 22 is formed with a through slot 222, and a protrusion 150 for inserting into the through slot 222 is vertically and fixedly arranged at a corresponding position on the top of the slider 15.
