[0029] Specifically, the needle plate 203 is connected stably with the shell 101, and the probes 204 mounted thereon are vertically aligned with the test points on the UUT. At this time, the limiting assembly (including the guide column 401, the guide sleeve 402, and the hinge 403) plays a role to ensure the accurate position of the needle plate 203 and the carrier plate 205 during the detection process, and prevent the deviation caused by external force or vibration.
