It is further characterized in that:
Between said inserted link lower end and the said inserted link lockhole is free-running fit;
The upper shell of said steering hardware has the inserted link lockhole;
The fastening end cover that is equipped with of the upper surface of said steering hardware, the upper surface of cover of the said end has the inserted link lockhole;
Said inserted link lockhole bottom is equipped with hollow position-limiting tube, and said hollow position-limiting tube is loaded in the internal cavities of cover of the said end, and the internal diameter of said hollow position-limiting tube equals the aperture of said inserted link lockhole;
The diameter upper surface diameter of said spacing round platform, lower surface diameter are all greater than the diameter of the through hole of said outer cover bottom;
Handle is equipped with on the top of said inserted link;
Said handle is the top suspension ring part of ringbolt, and the lower screw of said ringbolt partly is fastenedly connected the top of said inserted link;
The upper cover plate of said outer cover is detachable cover plate;
The lower end cylindrical of said spring is with sleeve pipe, and said sleeve pipe is supported on the upper surface of said spacing round platform.
After adopting structure of the present invention, because under the locking state: the locking side of mop is fastenedly connected outer cover, and inserted link runs through the upper and lower end face of said outer cover; Said inserted link lower end exposes to said outer cover lower surface, and the upper end of said inserted link exposes to said outer cover upper surface, and the spacing round platform of said inserted link is pressed on the bottom inner surface of said outer cover; Said inserted link is positioned at said outer cover in-to-in and partly is set with spring, and the two ends of said spring are mounted on the inside upper surface of said outer cover, the upper surface of said spacing round platform respectively, and the inserted link lockhole is installed on the said steering hardware; When mop, when steering hardware need be locked, only need to rotate mop, the bottom of inserted link can be along with its stroke of rotation automatic compensation of mop; Upper surface along steering hardware moves, and gos deep into the inserted link lockhole until the inserted link lower end, and spring can be guaranteed the position stability of inserted link; This state is locking, when mop need turn to, and releasing process; The upper end that only need upwards draw inserted link makes the inserted link lower end away from the inserted link lockhole, and mop just can freely rotate; After the release, inserted link returns to original position again under the effect of spring, waits for locking next time; It is simple in structure, installation difficulty is little when guaranteeing the automatic spacing function.
