Watch Band Adjustment Unit

Abstract

This invention concerns improved watch band adjustment unit, comprising a fixing unit, fixing pieces, rotating pieces on the left and right sides, and a passing fixing component. The fixing unit, fixing pieces, and rotating pieces form a first locking channel; the fixing pieces and rotating pieces form a second locking channel, with a locking limit portion. The fixing component is an interference fit rod or screw. When the rotating pieces are pulled and rotated, they compress an elastic member and disengage from the first fixing rod, allowing the adjacent adjustment unit to be mounted or dismounted, enabling quick assembly and reducing production costs.
