POLE SHAFT DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/159569
Kind Code:
A2
Abstract:
A pole shaft device according to the present invention comprises: an outer shaft (10); an inner shaft (20) which is arranged in the outer shaft (10) and slides along the inside of the outer shaft (10); a fixing member (30) which is fixed on the inner shaft (20) and has an inclined surface formed in the circumferential direction thereof; and an extension member (40) which is coupled to the outer shaft (10) so as to be movable in the longitudinal direction thereof, and is extended by friction with the inclined surface so as to fix the outer shaft (10) and the inner shaft (20). Since the inclined surface of the fixing member and the extension member interfere with each other so as to extend the extending member when the outer shaft or the inner shaft is relatively rotated, the pole shaft device according to the present invention has effects of conveniently fixing the outer shaft and the inner shaft and minimizing components used for selective fixing.
