Capacity-changing trash can

Abstract

The invention discloses a capacity-changing trash can which comprises an outer cylinder, an inner cylinder, a support component, a metal wire component, a rotating mechanism, a blocking nail, a falling-stopping ring, a spring and an upper bottom plate. The rotating mechanism is arranged at the bottom of the outer cylinder. One end of a rotating shaft is bent by 90 degrees and penetrates through the cylinder wall of the outer cylinder to be used as an operation handle. The other end of the rotating shaft penetrates through a fixing base and a rotating wheel and is connected with a blocking ring. The support component comprises two rod pieces and four idler wheel frames, and the middle portions of the two rod pieces are hinged together. The two ends of each rod piece are in contact with sliding grooves in the bottom of the outer cylinder and the bottom of the upper bottom plate through the idler wheel frames. The positions, close to the idler wheel frames, of the lower ends of the two rod pieces are connected with the rotating wheel through metal wires. The rotating wheel is driven to rotate through the operation handle, a metal wire component pulls the two rod pieces to drive the idler wheel frames to move in the sliding groove in the bottom of the outer cylinder, so that the two rod pieces are closed together or separated, the other ends of the rod pieces lift the upper bottom plate and the inner cylinder or put the upper bottom plate and the inner cylinder down, and accordingly the capacity of the trash can is changed.
