ANTI-SLIP DRIVING TOOL ADAPTED TO BE USED AT AN ANGLE OFF-AXIS TO OBJECT TO BE DRIVEN

Description

BACKGROUND OF THE INVENTION

The present invention relates to an anti-slip driving tool and, more particularly, to an anti-slip driving tool which is adapted to be used at an angle off-axis to an object to be driven.

Conventional driving tools such as hexagonal wrenches and screwdrivers are commonly used hand tools, which are used to drive fasteners, such as bolts or screws. However, the fastener is based on cost considerations and is a large number of consumables, the material used in the manufacture of the fastener is softer than that of the driving tool, so that the fastener will be damaged when driven by the driving tool. Furthermore, using a driving tool whose size specification does not match the fastener to forcibly drive the fastener will also cause the fastener to be damaged. The driving hole of the damaged fastener is rounded out in the hex corners so that the driving tool can not effectively drive it due to relative slippage.

In view of the above, a need exists for a driving tool that mitigates and/or obviates the above drawbacks.
