Abstract

The invention relates to an English listening earphone sleeve rapid wearing device. The device comprises an earphone sleeve and a shell, four pull ropes are arranged at an opening of the earphone sleeve, a blind hole is formed in the upper end face of the shell, a sliding block capable of interacting up and down is arranged in the blind hole, four belts are fixed to the upper end of the sliding block, the four pull ropes can be arranged on the outer side faces of the four belts in a sleeving mode respectively, four through holes are formed in the shell, a driving lever is connected in each through hole in a sliding mode, when the stand column moves downwards along with the sliding block, the driving lever can shift the uppermost pull rope from the belt, when the sliding block moves upwards, the driving lever can slide outwards along the through holes, the belt is fed by a certain distance, and the pull ropes on the outer side faces of all the belts are made to ascend by a height synchronously. According to the device, sleeving of the earphone sleeve is achieved in the mode that the pulling rope of the uppermost earphone sleeve can be pulled down from the belt through the driving lever every time the sliding block is pressed downwards, and the device is simple and efficient, and realizes repeated use for multiple times without the buckling phenomenon.
