摘要:
A blade driving assembly for an adjustable hair clipper of the present invention comprises a movable blade holder, a spring, a spring holder and a push lever. The spring is disposed with a coiled portion secured on the spring holder, a first portion which exerts pressure upon the movable blade holder to bias the movable blade towards the stationary blade and a second portion which biases the spring holder towards a retracted position. The push lever is driven to move forward or backward by an external force, and a front end of the push lever abuts against the rear end of the spring holder in such a way to push the spring holder forward when the push lever is driven forward, and when the push lever is driven backward, the spring holder is biased by the spring to retract until the rear end thereof abuts against the push lever.
