Abstract
A fastening device includes a holding base capable of sliding or rotating on a rod or column, a driving bolt rotatably coupled with a thrusting block rotatably engaged in the holding base having a driving wedge face formed on the thrusting block, and a follower block movably reciprocating in the holding base having a follower wedge face formed on the follower block and tangentially engageable with the driving wedge face of the thrusting block; whereby upon a rotation of the driving bolt to inwardly push the thrusting block in the holding base, the follower block will be thrusted by the driving block to interfere in a rod (or column) surface for quickly, ergonomically and firmly fastening the rod (or column) within the holding base.
