Easy-to-maintain power distribution cabinet wiring device

The invention relates to the technical field of power distribution cabinets, and specifically relates to an easy-to-maintain power distribution cabinet wiring device. The device comprises a power distribution cabinet body, mounting brackets, wire fixing devices and wire guiding devices. The device has the beneficial effects that the electrical elements are fixed on the mounting side plates of themounting bracket, and the mounting bracket is slidably connected with the guide rails arranged in the power distribution cabinet body through the slide rails at the bottom, so that the mounting bracket can slide outwards along the rails of the guide rails, and the electrical elements fixed on the mounting bracket can be inspected and maintained more conveniently. An electric wire connected with the electrical element is clamped in a wire clamping groove formed in the wire fixing base, insulating elastic pieces are symmetrically arranged on the two sides of a groove opening of the wire clampinggroove, and when the elec
