FIGs. 1-6 illustrate a first embodiment of the structure of the present invention, comprising a locking inner core 1, a fixing core 2 and a base 3.

An upper portion of the fixing core 2 is a circular sleeve tube 21; a lower portion of the fixing core 2 is formed by four resilient pieces 22; the resilient pieces 22 extend downwardly from a bottom surface of the circular sleeve tube 21; an outer side wall of each of the resilient pieces 22 is provided with a projection 23 having an upward slanted surface and a downward slanted surface respectively along a projecting direction of the projection, thereby form a wedge; inner threads are provided on both an inner side wall of the circular sleeve tube 21 and an inner side wall of the resilient pieces 22.

The base 3 is a tubular component; an outer side wall of a lower portion of the base 3 is opened with four windows 31; a quantity of the windows is the same as a quantity of the resilient pieces 22 of the fixing core 2. A top portion of the base 3 has a circular sleeve ring 32; four openings 33 are provide at a side wall of the sleeve ring 32.

The locking inner core 1 is a tubular component 1; an outer side wall of the locking inner core is provided with outer threads; a top portion of the locking inner core 1 is provided with a circular locking ring 11; a side wall of the locking ring 11 is provided with two pairs of screw holes 12 so that tightening screws 4 can be inserted to fix the locking inner core 1 and a faucet 10 together. An upper end of the locking inner core 1 is fixedly connected with the faucet 10; a lower portion of the locking inner core 1 is threadedly connected inside the fixing core 2; the base 3 sleeves the lower portion of the fixing core 2; the four resilient pieces 22 of the fixing core 2 protrude out of the four windows 31 of the base 3 respectively.

A method of installing the present invention: Inserting the inner core 2 into the base 3, wherein the base 3 is provided with four windows 31 on a side wall thereof and a circular sleeve ring 32 on a top portion thereof, and the four resilient pieces 22 of the fixing core 2 are resilient in nature and are compressible, and the four resilient pieces 22 are installed in correspondence to the four windows 31 of the base 3 after the fixing core 2 is inserted into the base 3; screwing the locking inner core 1 into the fixing core 2 until the locking inner core 1 reach upper ends of gaps between the resilient pieces 22; the locking inner core 1, the fixing core 2 and the base 3 are thus assembled to form an integral structure.

During installation, since the locking inner core 1 is screwed into the fixing core 2 until the locking inner core 1 reach the upper ends of the gaps between the resilient pieces 22, and the four resilient pieces 22 of the fixing core 2 are resilient and compressible, after the integral structure of the present invention is inserted from above a platform 20 into an installation hole of the faucet on the platform, continue to screw the locking inner core 1 clockwise for tightening purpose; as the locking inner core 1 continues to be screwed, the fixing core 2 is driven upward. Since the outer side of the fixing core 2 comprises wedges defined by the projections, a clamping force of the wedges of the fixing core 2 against the platform 20 will increase as the locking inner core 1 continues to be screwed. Further, as the locking inner core 1 will eventually be screwed into the fixing core 2 till the lower portions of the resilient pieces 22, there is no sufficient space provided at inner sides of the four resilient pieces 22 for deformation of the four resilient pieces 22, thereby securely fixing a base of the faucet on the platform 20. To disassemble, screw the locking inner core 1 anti-clockwise for loosening purpose until the locking inner core 1 returns back to the opening portion of the fixing core 2 from which the locking inner core 1 is screwed in, and the four resilient pieces 22 of the fixing core 2 can be compressed inwardly due to their resilience, such that the structure of the present invention can be conveniently removed from the platform 20.
