Abstract

The invention discloses a sucker. When the existing sucker is adsorbed onto the contact surface, air can be difficultly introduced into a negative pressure chamber between the sucker and the contact surface quickly, and the existing sucker cannot be taken off easily. Optimally, a convex surface is formed on the front side of a sucker body, and a pull rod is connected with the back side of the sucker body and penetrates through an adaptor body to be connected with a turnover handle. The air in the negative pressure chamber is exhausted as far as possible when the handle closes up to the adaptor body to form the negative pressure chamber, high vacuum degree of the negative pressure chamber can be ensured, and adsorption strength is ensured. The convex surface is formed on the front side of the sucker body when the handle turnovers from the adaptor body, the negative pressure chamber is quickly eliminated, and the sucker can be conveniently taken off from the contact surface. According to the sucker, by turning over the handle, the negative pressure chamber enabling the sucker to be adsorbed on the contact surface can be quickly formed on the front side of the sucker body or eliminated, and therefore, the sucker can be adsorbed on or taken off from the contact surface quickly and conveniently.
