The invention discloses a blasting pin safety valve for blasting operation. The safety valve comprises a valve body, a fixed sleeve, a fixing base and supporting rod sleeves, a pressure inlet and a pressure outlet are formed in the bottom and the right side of the valve body respectively, and a valve block is arranged between second limit blocks; the fixed sleeve is connected with the top of a blasting pin, a mounting hole is formed in the fixing base, and the supporting rod sleeves are fixed to the lower end surface of the fixing base; handles are arranged on the outer side of the fixing base, the handles are connected with compression plates through threaded rods, and the threaded rods are connected with the fixing base through mounting channels. According to the blasting pin safety valve for blasting operation, the telescopic supporting rod sleeves can be used for conveniently adjusting the pressure value of the safety valve, the handles and the threaded rods can be used for operating the device more conveniently, the compression plates can be used for being matching with the fixed sleeve and stably fixing the blasting pin, and the structure is more reasonable.
