Circuit breaker mounting structure

The utility model relates to the technical field of circuit breakers, and discloses a circuit breaker mounting structure, which comprises a mounting plate, a mounting frame is clamped on the front surface of the mounting plate, an adjusting mechanism is arranged in the mounting frame, and a clamping mechanism is arranged on the front surface of the mounting plate. The adjusting mechanism comprises a fixing assembly and a power assembly, and the power assembly is arranged at the bottom of the fixing assembly. The first clamping plate and the second clamping plate move inwards to clamp and fix the circuit breaker, bolts are not needed to fix the circuit breaker, the mounting and dismounting process of the circuit breaker is simplified, use of operators is facilitated, the mounting efficiency of the circuit breaker is improved, time and labor are saved, the mounting frame is clamped and fixed to the front face of the mounting plate, and the mounting efficiency is improved. Therefore, the installation of the inst
