Failure loop detection device for circuit breaker

The invention relates to the technical field of circuit breaker detection, in particular to a circuit breaker failure loop detection device which comprises a base and a circuit breaker, a plurality of pop-up grooves are formed in the top end of the base at equal intervals, sliding grooves are symmetrically formed in the inner side wall of each pop-up groove, and the other end of an adapter is electrically connected with a detection connecting line. The detection connecting wire is electrically connected with the guide connecting assembly, and a plurality of cleaning assemblies are fixedly installed at the bottom end of the top plate at equal intervals. If a failure loop is normal, a circuit can be disconnected, magnetism of a second iron core disappears, under the elastic effect of a fourth spring, a push plate is pushed to push a wedge-shaped plate into a mounting groove, limiting on a sliding block is relieved, the sliding block and an insertion rod are driven to move under the elastic effect of a third spr
