Abstract

The utility model provides a resistance detection tool which comprises a base, a plurality of copper columns are arranged on the base, one end of the base is provided with a rotating column, the rotating column is rotatably connected with a rotating piece, the rotating piece is movably connected with a pull rod, the pull rod is parallel to the base, and the copper columns are arranged on the base. A plurality of probe holes are formed in one end, far away from the rotating column, of the pull rod, the pull rod comprises a head part and a tail part, the head part is connected with one end of the tail part, the head part is rectangular, the tail part is strip-shaped, and the probe holes are formed in the head part. Through the arrangement of the pull rod and the rotating piece, the position of the probe is adjusted. The probe hole in the pull rod can directly fix a probe, the second screw hole in the rotating piece is used for quickly locking the telescopic length of the pull rod, and the rotating piece is matched with the rotation of the shaft sleeve, so that a to-be-tested resistance point on the PCB can be efficiently positioned, the manual adjustment time is remarkably shortened, and the test flow efficiency is improved.
