Referring to Fig. 1 and Fig. 2, supporting structure of the present invention is for the support of shrinkage fingerstall, including cross section is arc-shaped
Two hard structure bulk-breakings 10, two hard structure bulk-breakings 10 form cylindrical shape by the corresponding nested encryptions of lateral edges.
In the present embodiment, the lateral edges of two hard structure bulk-breakings 10 is respectively equipped with groove 11, shape between adjacent grooves 11
Becoming double wedge 12, the double wedge of the groove of the lateral edges of one hard structure bulk-breaking 10 the 11st, double wedge 12 and another hard structure bulk-breaking is the 12nd,
Groove 11 corresponding nested encryptions respectively.
Preferably, two hard structure bulk-breaking 10 sizes of supporting structure are identical, and certainly, two hard structure bulk-breakings 10 also may be used
With small one and large one, as long as hard structure bulk-breaking 10 can form cylindrical shape by nested encryptions two-by-two.
Preferably, described supporting structure is rigid plastics part.
Preferably, the outside diameter of cylinder of two hard structure bulk-breaking 10 one end of described formation supporting structure is more than the other end
Outside diameter of cylinder.When being applied to shrinkage fingerstall, two hard structure bulk-breakings 10 are assembled into the less one end of outside diameter of cylinder from it and support
Enter the big opening end of shrinkage fingerstall.
Refer to Fig. 3, Fig. 4 and Fig. 5, when supporting structure of the present invention is applied to the installation of shrinkage fingerstall, shrinkage fingerstall 20
One end is big opening end 21, and the other end has some osculum ends 22, and the using method of supporting structure is as follows：First, shrinkage is referred to
Set 20 expansion the big opening end 21 supporting shrinkage fingerstall 20 with supporting structure, support the osculum end of shrinkage fingerstall 20 with support bar
22, it is placed into after cable 50 specifies position at shrinkage fingerstall 20, first extract osculum end support bar out, choose the big of shrinkage fingerstall 20
Arbitrary hard structure bulk-breaking 10 at mouth end 21, radially this hard structure bulk-breaking 10 of pinching makes it be slightly distorted inside, uses simultaneously
External force is released hard structure bulk-breaking 10 and takes out, and in like manner then releases other hard structure bulk-breaking 10 and takes out.
Preferably, in advance the big opening end 21 of shrinkage fingerstall 20 was turned down from inside to outside necessarily before shrinkage fingerstall 20 expansion
Distance, for example, turn down at P line.
Preferably, when turning down before shrinkage fingerstall 20 expansion, on two shrinkage fingerstall 20 contact surfaces equably
