Abstract

The utility model discloses an elastic resetting sucker which comprises a sucker body that can adsorb on a surface of an object. A bottom surface of the sucker body dents inwards and a suction chamber is formed. A periphery of the suction chamber is provided with a closed ring surface which is in a same plane. According to the utility model, an elastic resetting member which causes the sucker body to reset to the back surface is provided in the suction chamber. The elastic resetting member comprises a telescopic sleeve and an elastic member which is provided in the telescopic sleeve. The elastic resetting member is provided at an intermediate position of the suction chamber and is connected with the sucker body. In using, the sucker body is squeezed on an operation surface for discharging the air in the suction chamber and forming a closed space. Then the hand is loosened, and the elastic resetting member jacks the sucker body in a back direction of the sucker body through the resetting elastic force itself thereby effectively enlarging the space of the closed space, reducing the pressure in the closed space, increasing a pressure difference between the inner space and the outer space of the sucker body, increasing a suction force of the sucker member and obtaining firmer suction.
