Steal the flower pattern slot that the flower pattern of screw matches.
It improves again, the side in the hexagonal portion of the bolt seat radially offers a blind hole, and steel ball is telescopically limited in blind hole
Interior, being equipped with to offset with steel ball in blind hole makes steel ball have always the spring of pop-up trend outward.
Further, the small one end of the diameter of the sleeve coaxially offers the through-hole placed for mandril, and the aperture of through-hole is small
In the aperture of Hexagon hole.
Further, the through-hole is square hole, and the section of mandril is corresponding rectangular.
Finally, milling is at the hexagonal structure being connected convenient for spanner on the outside of the small one end of the diameter of the sleeve.
Compared with the prior art, the advantages of the utility model are: bolt seat is by steel ball and sleeve connection, not only connection is steady
It is fixed reliable but also detachable, when needing replacing, bolt seat can be ejected by mandril, it is very convenient；Sleeve is equipped with interior hexagonal
Hole, bolt seat is equipped with the hexagonal portion of corresponding grafting, so that grafting rear stability is good, it is not in slipping phenomenon.The utility model knot
Structure advantages of simple, bolt seat dismounting and change are convenient, in actual use, it is only necessary to which a sleeve can arrange in pairs or groups multiple bolt seats, no
Using only convenience, while also reducing cost.
