Title:
PIPE CLEANING MACHINE FOR DRIVING DEVICE OF SPRING SHAFT
Document Type and Number:
Japanese Patent JPH08318238
Kind Code:
A
Abstract:
To exclude such a trouble that a rotatable structural part protruding from a mechanical casing rolls up other bodies and to make it unnecessary to separately operate coupling jaws for cleaning and/or replacement.
One end art of a hollow shaft is nonrotatably connected with respect to a coupling casing 9 which has the inside diameter larger than that of the hollow shaft and whose circumference is at least substantially closed. Further, a jaw holder 14 is supported within the coupling casing 9 so as to be not relatively rotatable together with the coupling jaws 28, 29 but extractable in the axial direction.
