In the present invention, a vertical wall 54 is provided between the lower end of the second inverted cone surface 56 and the upper end of the first inverted cone surface 52, so as to play a role of transition between the second inverted cone surface 56 and the first inverted cone surface 52.

In the present invention, the first female thread section 51 is located at a lower portion of the fork leg 5. By providing the first internal thread section 51 at the lower part of the fork foot 5, the fork foot 5 can be held better in engagement with the machine element 8 by the first internal thread section 51 when the locknut 4 is rotated.

In the present invention, the upper end of the base body 1 is provided with a top plate 6. In the mounted state, the top plate 6 at the upper end of the base body 1 is closely attached to the lower surface of the mounting table, thereby preventing the member 8 (i.e., the faucet) from being loosened.

The utility model discloses in, the bottom of roof 6 is equipped with the grip block 7 that is used for centre gripping locknut 4 to make the outside atress of grip block 7 warp under the effect of the jacking power of locknut 4.

In the present invention, the inner side of the holding block 7 is formed with a holding inclined plane 71 inclined outward from top to bottom. Through the inboard at grip block 7 set up from top to bottom the centre gripping inclined plane 71 that leans out for during locknut 4 upwards rotates, make things convenient for grip block 7 can outwards be out of shape under the effect of locknut 4 thrust upwards, drive the bottom of roof 6 and mount table closely and laminate simultaneously, reach dual locking effect.

The utility model discloses in, the quantity of grip block 7 is 2, and two the grip block 7 symmetry sets up in the both sides of base body 1. Two clamping blocks 7 are symmetrically arranged on two sides of the base body 1, so that the locking nut 4 can apply acting force to the top plate 6 on two sides simultaneously, the attaching effect of the top plate 6 and the mounting table is increased, and a better locking effect is achieved.
