Abstract
The utility model relates to a telescopic suction pipe of suction cleaner. The utility model comprises an outer pipe, an inner pipe, a stopping piece and a pressing piece, wherein the outer pipe and the inner pipe can be locked axially by matching the stopping piece and the stopping groove on the inner pipe, and the pressing piece can be pressed on the stopping piece in a moving way. A rotating piece is arranged above the pressing piece, the rotating piece and the pressing piece are movably connected with each other, and the outer edge part of the rotating piece is provided with a lever arm. The rotating piece can rotate by pushing the lever arm to move, therefore the pressing piece can be driven to move axially. According to the lever principle, the length of the arm of force of the force which the lever arm bears is far greater than the length of the arm of force of a pull force exerted to the pressing piece from the rotating piece, therefore the external force which needs exerting for pushing the arm of force is far smaller than the pull force which needs exerting for the move of the pressing piece.
