Position on part excircle below guide groove is provided with fluted disc, and the helical tooth coordinated with push rod helical tooth is provided with fluted disc
Groove, by spiral alveolar and push rod driving push rod can be coordinated outwardly or inwardly to be slided along guide groove when fluted disc rotates；Shaft end with
Push rod relevant position outer surface is provided with stopper slot, and push rod the inner, which can extend into, provides axial limiting in stopper slot；
The placing chamber wall portion of the shaft housing connector uniformly has three guide grooves, and push rod is both provided with each guide groove；
The push rod is inner to be less than the 1/2 of spacing groove depth for wedge shape, wedge shape height；
The push rod is inner to be and the conical adaptable V-arrangement of push rod for cone, stopper slot；
Position on the shaft housing connector excircle below guide groove is provided with toroidal cavity, and fluted disc is placed in annulus
In connected in star；
Annular knurl is provided with the fluted disc excircle.
The shaft coupling with axial limiting of the present invention, in the placing chamber wall portion mounting circular ring of shaft housing connector fixed connection shaft
Shape fluted disc and the push rod for being similar to worm structure, rotation fluted disc coordinate driving push rod to extend inwardly into shaft end limit along guide groove with push rod
Position groove in provide axial limiting, further rotate fluted disc driving push rod hold out against shaft end provide radially it is spacing, axle can be provided simultaneously
Simple in construction to spacing with radially spacing, installation operation is convenient, and connection is reliable.
