Multi-in-line metal tube shell insulation resistance testing device

The invention relates to a multi-in-line metal tube shell insulation resistance testing device which is characterized in that two flexible arms (2) are connected onto an insulation base (1), each flexible arm is connected with a probe base (3), and a metal probe (4) is connected onto each probe base; a copper sheet (8) is connected to the middle of the insulation base; a tube shell clamp (5) is additionally arranged, and an array of through holes (6) corresponding to the pins of the multi-in-line metal tube shell are formed in the tube shell clamp (5). When the device is used, input and outputwires of the insulation resistance tester are clamped at the bottoms of the two probes through alligator clips, the multiple columns of pins of the multiple columns of metal tube shells 7 are inserted into the through holes in the clamp, the metal tube shells are attached to the copper sheet of the base, and the probes are moved to touch the pins in the corresponding round holes, so that the insulation resistance among a
