The specific embodiment

Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.

Embodiment 1:

A kind of expansion link, comprise the body of rod that is nested together and forms by big bar 1 and little bar 2, the end that little bar 2 is inserted in big bar 1 fixedly has a taper thing 3, described taper thing 3 is provided with first external screw thread 34, be arranged with an expansion-head 4 made from elastomeric material in taper thing 3 usefulness, described expansion-head 4 inwalls are provided with the internal thread corresponding with first external screw thread 34, rotation taper thing 3 can make the inwall of expansion-head 4 and big bar 1 excessively be full of and close, the top of big bar 1 is set with first support 6, the top of little bar 2 is provided with second support 7, described second support 7 is provided with screw rod 71, screw rod 71 is provided with second external screw thread 72, inside, top at little bar 2 also is set with retainer plate 21, and retainer plate 21 is provided with the internal thread corresponding with second external screw thread 72.

Embodiment 2:

The top of described taper thing 3 is provided with collar 31, is provided with reducing 32 behind the collar 31, and taper thing 3 afterbodys are provided with foundation ring 33.

Described expansion-head 4 one ends are osculum 44, and the other end is big mouthful 43, and Bian Shangyou passes through the breach 42 of big mouth 43 and osculum 44 together.

Osculum 44 diameters of described expansion-head 4 are less than the diameter of collar 31, and big mouthful 43 diameter is less than the diameter of foundation ring 33.

The outer wall of described expansion-head 4 also is provided with the shirt rim 41 of at least 3 projectioies.
