摘要： The present invention relates to a single-hole puncher with ease of alignment comprising a base and a punching unit; the punching unit is disposed on the base; a hole is disposed on the base in a position corresponding to the punching unit; a L-shaped right-angle receptacle with two vertical flanges is disposed between the base and the punching unit; the punching unit and the right-angle receptacle are vertically disposed facing each other. Since the L-shaped right-angle receptacle of the present single-hole puncher allows convenient and efficient paper alignment, the present invention, in comparison with available single-hole punchers, has the advantages of being simple in construction, easy to operate, convenient to be carried around and of high punching efficiency and precision. It can also punch binding holes of various distances in between. The structure of the L-shaped right-angle receptacle can be widely applied to various types of single-hole punchers and even two-hole (multiple-hole) punchers.

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.
