Column switch with safety protection device

The invention relates to the technical field of pole-mounted switches, and discloses a pole-mounted switch with a safety protection device, which comprises a circuit breaker assembly, a driving assembly arranged on the side surface of the circuit breaker assembly, a power-off assembly arranged in the circuit breaker assembly, and a switching assembly arranged at a position corresponding to the power-off assembly in the circuit breaker assembly, a detection assembly is arranged at the position, corresponding to the power-off assembly and the switching assembly, in the circuit breaker assembly, and an auxiliary assembly is arranged on the side face of the circuit breaker assembly. A second matching block is elastically supported by a third spring, so that a second pressing block continuously extrudes the side face of a pull block in an elastic extrusion mode, and interference to rotation of a connecting rod is avoided; similarly, the first gear is firstly stressed to drive the isolating knife switch to be elect
