Abstract: A cloth attachment device includes a frame, and further includes: a first roller arranged on the frame and capable of being rotated around its axis relative to the frame; a transmission mechanism arranged on the frame and capable of being moved relative to the frame, a to-be-attached cloth being arranged between the first roller and the transmission mechanism, two opposite surfaces of the to-be-attached cloth being in contact with a first position on the transmission mechanism and a second position on the first roller, respectively; and a driving mechanism configured to drive the first roller to rotate and drive the transmission mechanism to move in such a manner that the first position and the second position are moved in an identical direction, thereby to enable, through the transmission mechanism, the to-be-attached cloth between the first roller and the transmission mechanism to be curled up around the first roller.

Abstract: The present disclosure discloses an auto-switching tee joint, including a transitional tube, a first inlet tube, a second inlet tube and an outlet tube. The first inlet tube and the second inlet tube are disposed at two ends of the transitional tube, and the outlet tube is connected at a side wall of the transitional tube. In the transitional tube, there is provided with a switching ball which is movable freely. Both the first inlet tube and the second inlet tube have a bell-mouth which faces the transitional tube. The switching ball has a diameter larger than a minimum inner diameter of the bell-mouth and larger than an inner diameter of the outlet tube. The present disclosure further provides a device for washing and drying clamps which adopts the above auto-switching tee joint and can accomplish the washing and drying of clamps, save costs and improve working efficiency.
