Then, the test height of the test probe 712 is adjusted through the electric telescopic rod 711. When it is necessary to adjust the positions of multiple test probes 712, the second servo motor 715 is started. The output shaft of the second servo motor 715 drives the connecting member 713 to adjust the angle. At this time, under the action of the connecting block 714, the electric telescopic rod 711 is driven to move on the surface of the second moving seat 710, thereby adjusting the positions of the test probes 712, thus improving the test effect of the test device.
