Clamp for testing circuit breaker

The utility model relates to the technical field of mechanical automation, and particularly discloses a clamp for testing a circuit breaker. According to the clamp for testing the circuit breaker provided by the utility model, the second ends of the handles are held by hands to enable the first ends of the handles to rotate relative to the clamp body, so that the distance between the first ends of the two handles is increased, and the first ends of the two handles are convenient to clamp a convex part in the middle of the circuit breaker; the elastic piece enables the first ends of the two handles to have a trend of clamping the circuit breaker, so that the clamp is stably fixed on the circuit breaker; after the clamp is fixed on the circuit breaker, the first end of the probe is conductively connected with the wire holder of the circuit breaker, and the test power supply is connected with the second end of the probe, so that the test of items such as voltage, current, power, leakage current and electric ener
