Preferably, the telescopic limiting part is detachably mounted between the 2 fixing rings.

Preferably, the both ends symmetry of flexible locating part is equipped with the connecting block, be equipped with the spread groove that uses with the connecting block cooperation on solid fixed ring's the lateral wall, be equipped with spacing hole in the spread groove, have the locking lever that uses with spacing hole cooperation through compression spring slidable mounting in the connecting block.

Preferably, the connecting block is provided with an unlocking rod which can separate the locking rod from the limiting hole in a sliding and penetrating manner.

Preferably, the number of the telescopic limit pieces is greater than or equal to 3.

The beneficial technical effects of the utility model are as follows: the telescopic length of the telescopic limiting part is fixed and is connected between the fixing rings, so that the tensile length and the compression length of the spring wire can be limited, the elastic failure of the spring wire can be prevented, and the telescopic limiting part can prevent the spring wire from deviating and shaking when the fixing rings stretch or compress the spring wire;

the flexible locating part demountable installation can change flexible locating part between 2 solid fixed rings, when damaging, only need to change damage the part can, save the cost.
