Through this structure, make the outer loop can form free rotation for the inner ring when the becket is whole not locked and adjust to conveniently adjust the position orientation of outer loop ground connection end, compare above-mentioned integrative becket structure, the construction operation of working a telephone switchboard is more convenient.

The end face of the small hole end of the taper hole of the outer ring is provided with a pipe sleeve in an integrated mode, the pipe sleeve is sleeved with a pipe fitting butted with the metal pipe joint to be positioned, and the end portion of the pipe fitting forms an inner thread connector matched with an outer thread of the metal pipe joint. Through this structure, further improve the reliability of being connected counterpoint between becket and the corresponding pipe fitting.

The conical surface of the inner ring is uniformly provided with inward-concave sliding stopping grooves along the circumferential direction. Through the structure, the locking and the guide connection between the outer ring and the inner ring in the metal ring are more reliable.

The utility model has the advantages that the whole structure is comparatively simple, and equipotential ground connection is comparatively convenient, reliable, and application scope is wide, is fit for as the metal electric wire union coupling, all kinds of material water pipe ground connection, if: the structure of various pipes such as stainless steel pipes, galvanized steel pipes, steel-plastic pipes, copper water pipes, PPR, UPVC and the like or similar products is improved.
