The invention provides an automatic extensible and retractable washing device. The automatic extensible and retractable washing device comprises a rotary table which is horizontally put. Adjusting modules which are evenly distributed are arranged on the edge of the rotary table. The middle inside each adjusting module is provided with a vertical sliding ring, each sliding ring is internally provided with a sliding block which can slide up and down, and each sliding block is fixedly connected with a water outlet pipe which upwards extend. The side face of each sliding block is provided with a connection block which extends out of the edge of the outer side of the rotary table, and the outer end portion of each connection block is provided with an upper magnetic block. The outer side of the rotary table is fixedly provided with an annular track strip which surrounds the rotary table, and lower magnetic blocks are evenly distributed in the track strip. The automatic extensible and retractable washing device is similar to a traditional filling washing structure, and accordingly the traditional washing equipment can be improved conveniently; and meanwhile by means of the magnetic attraction force and repulsive force between the upper magnetic blocks and the lower magnetic blocks, the up-down sliding heights of the water outlet pipes are controlled, and therefore the purpose of controlling the depths of the water outlet pipes extending into empty bottles is achieved, and the flushing and drying effects are greatly improved.
