At this time, the signal line connected to the needle 124 passes through the connector body 121 and extends to the outside.

[0064] After the connector body 121, the connecting sleeve 123 and the needle 124 are fixed, the connecting sleeve 123 is inserted into the lower side of the mounting seat 10 from bottom to top, and then extends into the mounting seat 10 and the fixing assembly 11 in sequence, until the needle 124 fixed on the connecting sleeve 123 pierces the insulating layer of the wiring harness to be tested and contacts the conductor in the wiring harness to be tested. At this time, the signal line connected to the needle 124 is connected to the multimeter, and the voltage, resistance, etc. of the wiring harness to be tested can be measured, so that the point test of the wiring harness to be tested with related faults can be completed.

[0083] At this time, the driving member 113 drives the moving member 112 to move relative to the fixed sleeve 13, so that the moving member 112 is close to the clamping block 111.
