Directly wirerope 1 can be still limited when the external tensile force of pedestal 5.
When wirerope 1 is by external tensile force perpendicular to pedestal 5, cating nipple will not play limit to wirerope 1
Effect, two extension springs 9 are stretched, and the steel wire loop 10 on wirerope 1 is pulled and set by contacting with connection base ring 11
It is standby；After external tensile force disappears, two extension springs 9 can allow steel wire loop 10 to be restored to home position.
As shown in (a) in Figure 14, the case where when wirerope 1 is not affected by the external tensile force non-perpendicular to pedestal 5；Such as Figure 14
In (b) shown in, the universal joint outer ring 3 when wirerope 1 is by external tensile force non-perpendicular to pedestal 5, in cating nipple
It rotates by a certain angle, guarantees the radial angle offset of universal joint inner ring 2；Thread spindle 6 passes through spiral shell under the offset of universal joint inner ring 2
One of limit cylindrical piece 15 is relatively pressed into wire rope hole 13 by line fit system, and limiting cylindrical piece 15 at this time can will
Wirerope 1 limits, and the steel wire loop 10 on wirerope 1 can not be contacted with connection base ring 11；So external tensile force is assigned to
On cating nipple, the mechanical wear generated is contacted with the multi-angle of connection base ring 11 so as to avoid steel wire loop 10, is risen
To the purpose for protecting the intensity of wirerope 1 not reduce.
In conclusion the present invention adapts to the extraneous pulling force to 1 different angle of wirerope by cating nipple, solve
Steel wire loop 10 and the generated mechanical wear of multi-angle friction for connecting base ring 11, avoid because 10 intensity of steel wire loop drops
It is low that wirerope 1 is caused to be broken caused potential risk, play the purpose for protecting the intensity of wirerope 1 not reduce.The present invention
It is simple and compact for structure, there is preferable practical function.
