[0034] The back of the resistance tester 1 is connected to the mounting assembly 3;

At this time, the magnet 304 will be adsorbed onto one side of the adsorption iron plate 301, so that the resistance tester 1 can be hung on the surface of the lightning receiving strip. Then, the power-on clamp can be connected to the resistance tester 1 to hang the resistance tester 1, so that the operator can operate with both hands, further ensuring the convenience of resistance testing and improving testing efficiency.
