The invention provides wiring slotting equipment for a building wall. The wiring slotting equipment comprises a bearing plate. A gas spring hydraulic rod is arranged between the inner wall of the bearing plate and an upper containing plate. A sealing ring is arranged at the middle end of each walking tooth. A telescopic rod and a built-in spring are arranged in each sealing ring. The slotting equipment not only walks stably, but also can be adjusted in height. Multiple penetrating holes are formed at equal intervals and the number of the penetrating holes is larger than that of spring pins sothat the equipment height can be set between a fixing plate and an adjusting plate. An annular groove is formed in the side face of the end, facing an execution motor, of the adjusting plate. A fastening bolt penetrates a fixing block and is arranged in the annular groove. A rotary rod penetrates the fixing plate and the adjusting plate and is fixed to the execution motor, the angle adjustment canbe directly conducted by the adoption of the equipment, a pull-out rod, adjusting bolts and the fixing plate are arranged on the upper end face of the bearing plate, and walking wheels are arranged on the lower end face of the bearing plate, so that the equipment is simple in structure and easy to operate.
