Abstract

This invention relates a structure of universal shaft with adjustable tightness, comprising a through hole provided on the universal shaft main body passing through the ball bodies on the two ends thereof, a conical socket provided inside the distant end of the two ball bodies, and a bolt installed in the ball bodies and the main body matching with a nut for locking and fastening. The tightening and loosening of the bolt is used to make the ball bodies expand and return to their original shape, to enable the ball bodies to form locking or unlocking on the inner wall of a holding element, so as to achieve the objective of adjusting the angular displacement of the holding element.
