Connector 17, chuck 17-1, ejector pin is caught in deep trouth 17-2, and ejector pin is caught in shallow slot 17-3, outer handwheel 18, restoring spring 19.
Embodiment
See Fig. 1-4, concrete structure is as follows：Being assembled in the interface of cylinder valve on mandrel 1, mandrel 1 has positioning spigot, cylinder valve
Interface connects handle 3 by internal thread, and the left end of handle 3, which withstands positioning spigot, positions mandrel 1, and back-up ring is set on mandrel 1
4。
Another to set an outer connector 17, the periphery of outer connector 17 is fixedly connected with nonmetallic outer handwheel 18, connected outside
