The invention discloses a switch cabinet convenient to maintain. The cabinet comprises a cabinet body, a mounting plate is fixedly connected to the interior of the cabinet body, a mounting groove is formed in the top of the mounting plate, a mounting block is arranged in the mounting groove, a connecting block is fixedly connected to the top of the mounting block, a fixing plate is fixedly connected to the top of the connecting block, and a first fixing rod is fixedly connected to the outer surface of the fixing plate. According to the invention, an electric push rod, the fixing plate and themounting groove are arranged, with the operation of the electric push rod, the fixing plate is pushed out through the mounting groove; the equipment is pushed out to facilitate inspection and maintenance by personnel. By arranging a rack, a gear, a connecting shaft and a clamping rod, the connecting shaft drives the clamping rod to rotate by utilizing relative rotation of the rack and the gear, sothat a circuit is installed, and by arranging a pull rod, a sliding block and a sliding groove, the pull rod is pushed upwards, and the sliding block pushes the gear to be in contact with the rack, so that closing and loosening of a single circuit are controlled, and maintenance time is saved.
