The invention discloses a wrist wear type automatic inflation buoyancy life-saving ball. The wrist wear type automatic inflation buoyancy life-saving ball comprises a wrist band, an air bottle and an inflation air bag. A main shell is arranged on the outer side of the wrist band. An installing hole is formed in the main shell in the length direction of the main shell. One end of the installing hole is connected with an air bottle opening of the air bottle. An ejector pin capable of moving in the length direction of the installing hole is sleeved with the installing hole. The end, close to the air bottle, of the ejector pin is provided with a pin tip for puncturing a close cover of the air bottle. The end, located on the pin tip, of the installing hole is provided with an air outlet, and the air outlet is communicated with an outlet of the air bottle and communicated with the inflation air bag through an air pipe. The pin tip of the ejector pin is sleeved with a reset spring, when the reset spring is in an initial state, the pin tip is located in the station making no contact with the close cover of the air bottle, and when the reset spring is located in a compression state, the pin tip is located in the station where the close cover of the air bottle can be punctured. The wrist wear type automatic inflation buoyancy life-saving ball is simple in structure and convenient to operate and carry, the defect that traditional life-saving equipment is heavy is effectively overcome, and risks of water activities are effectively reduced.
