The invention relates to a wireless single hoisting point automatic open-close grab bucket. The grab bucket comprises two hoppers, two pull rods, a rod joint, a sliding hoisting hammer, two steel wire ropes and a single action cylinder, wherein the sliding hoisting hammer and the single action cylinder are arranged on a hinge shaft; the upper end of the single action cylinder is connected with the sliding hoisting hammer; the lower end of the single action cylinder is fixedly connected with the hinge shaft; the lower ends of the two steel wire ropes penetrate through the sliding hoisting hammer and are fixedly connected with the rod joint respectively; the single action cylinder comprises a cylinder barrel, a piston rod and a piston. According to the invention, a wireless one-way electromagnetic restricted valve is adopted to work; driving power is very low; power source driving the micro-motion restricted valve can be provided with power by a mobile phone lithium battery; the lithium battery is replaced for one time from three to five years; the grab bucket is not switched in by power source; complex electrifying material consumption facilities of cable drum, hanging cable, central slip ring, power source connector assembly, and the like are eliminated; various failures of electrifying facilities are avoided.
