when the guide rod 20 moves upwards, the swinging piece 26 rotates under the action of air flow in the piston cylinder 23 and is attached to the upper side of the guide hole 25, at the moment, air in the upper cavity of the piston cylinder 23 can only flow into the lower cavity of the piston cylinder 23 through the damping hole 27, the operation reduces the speed of upwards moving and resetting the guide rod 20, the time for the guide groove 21 to communicate the spherical shell 17 with the water inlet hole 9 is prolonged, water in the spherical shell 17 can be sufficiently discharged, and the expansion strip 8 is extended to the position; when the movable ring 12 rotates and moves in the combination ring 11, the elastic element 13 is stretched and twisted, and then the lubricating oil in the elastic element 13 is extruded and is sprayed out through the through hole 28 and sprayed in the spiral groove in the combination ring 11, so that a lubricating effect is provided for the relative rotation between the combination ring 11 and the movable ring 12, the problem that the movable ring 12 cannot rotate due to excessive friction is avoided, and when the lubricating oil in the elastic element 13 is used up, the lubricating oil can be supplemented into the elastic element 13 through the material supplementing hole 29; through the arrangement of the small ball 30 and the elastic strip 31, under the natural relaxation state of the elastic element 13, the small ball 30 can be tightly pressed on one side of the through hole 28 and seal the through hole, so that the problem of excessive lubrication caused by leakage of lubricating oil in the elastic element 13 is avoided, the purpose of saving the lubricating oil is achieved, and when the elastic element 13 is stretched and twisted, the lubricating oil in the elastic element pushes the small ball 30 away and is extruded outwards, so that normal lubrication work is provided.
