BACKGROUND OF THE INVENTION
[0001] The present invention relates to a fastener driver and, more particularly, to an anti-slip fastener driver.
[0002] A conventional fastener driver, such as a hexagonal wrench, a screwdriver, etc. is a hand tool that is usually used to driver a fastener, such as a bolt or a screw. Considering the costs and the fact that the fasteners are common expendables, the fasteners are generally made of materials softer than the fastener drivers, resulting in wear of the fasteners while being driven by the fastener drivers. Furthermore, a fastener forcibly driven by a fastener driver of a size not matching with the fastener will wear, too. The wear of a fastener result in damage to a driving hole of the fastener. In a case that the driving hole of the fastener becomes a nearly circular hole, when the fastener driver engages with the driving hole and rotates to drive the fastener, the fastener driver slips relative to the fastener, failing to effectively drive the fastener.
BRIEF SUMMARY OF THE INVENTION
[0003] In a first aspect of the present invention, an anti-slip fastener driver comprises a shank and a driving portion formed on an end of the shank and defining a longitudinal axis. The driving portion includes an outer periphery surrounding the longitudinal axis and having a first peripheral face. An end of the driving portion opposite to the shank includes a first end face connected to the first peripheral face. The first end face includes a first side and a first angle located outside of the first side. The end of the driving portion opposite to the shank includes a reference plane perpendicular to the longitudinal axis. The first side is located on the reference plane. An end of the first side is adjacent to the longitudinal axis. Another end of the first side opposite to the longitudinal axis is connected to the first peripheral face. The first angle is located between the reference plane and the shank.
[0004] In a second aspect of the present invention, an anti-slip fastener driver comprises a shank and a driving portion formed on an end of the shank and defining a longitudinal axis. The driving portion includes an outer periphery surrounding the longitudinal axis and having a first peripheral face. An end of the driving portion opposite to the shank includes a front conical face and a first end face. The front conical face is a conical face centered at the longitudinal axis. The first end face is connected to the first peripheral face. The first end face includes a first side and a first angle not located on the first side. The first side is located on the front conical face. An end of the first side is adjacent to the longitudinal axis. Another end of the first side opposite to the longitudinal axis is connected to the first peripheral face. The first angle is located between the front conical face and the shank along the longitudinal axis.
