The lifting rod locking device comprises an electric lifting rod, a plurality of locking mechanisms used for locking the electric lifting rod and an equipment body, the electric lifting rod is composed of a plurality of lifting sections which are sequentially connected in a sliding and sleeving mode, and the middle of the equipment body is a columnar hollow part. The multiple locking mechanisms are installed on the inner wall of the hollowed-out part of the equipment body at equal intervals and surround the outer side of the electric lifting rod, and the electric lifting rod perpendicularly penetrates through the hollowed-out part of the equipment body. Locking and unlocking of equipment on different lifting sections of the electric lifting rod are achieved, the transportation safety and work safety of the equipment are guaranteed, and long-term economy is achieved.
