According to another embodiment of the present utility model, the end of the protrusion axle of described transitional extension rod arranges screw and packing ring, described packing ring is fixed on the end of described protrusion axle by this screw, described packing ring is positioned at described second hollow section, is stopped to described first hollow section slide by described stage portion.
According to another embodiment of the present utility model, described spring is Rectangular Spring.
According to another embodiment of the present utility model, described base arranges socket cap screw.
The utility model can also be:
According to another embodiment of the present utility model, described base arranges socket cap screw.
Compared with prior art, one of the beneficial effects of the utility model are:
A kind of spring of the present utility model compresses leak detection fixture, the part flatness after compression can be made to be out of shape controlled, do not produce distortion part, improve part qualification rate by the elastic deformation of spring.
