The engagement cavity is specifically positioned offset from the first lateral edge by a first distance and positioned offset from the second lateral edge by a second distance.

Description

Multi-clamping point socket bit

The present invention relates to a tool for loosening and locking fasteners (such as screws and nuts), in particular to a non-slip multi-directional screwdriver head, which can prevent the screwdriver head from being damaged during the process of removing or locking the fastener The fastener may slip off the fastener.

Hexagon bolts, nuts, screws, and other similar threaded fasteners are combined with complementary threads (usually so-called female threads) to fix multiple parts together. The structure of this type of fastener generally includes: a cylindrical shaft with external threads, and a head at the tail end of the shaft. This external thread is combined with a complementary female thread to fix the fastener and the related parts at the same time. The female thread is usually formed by tapping into a hole or nut. The fastener is rotated or driven into the female thread by receiving an external torque on its head. The shape of the head is made to allow an external tool, such as a wrench, to apply a torsion force to the fastener to rotate the fastener and to some extent join the complementary female thread. Such fasteners are simple, cheap, and very effective, so they are commonly used in modern society.

One of the common problems with using this type of fastener is that the tool often slips on the head regardless of whether the fastener is male or female. The reasons may be: wear of tools or fasteners, corrosion of tools or fasteners, excessive tightening of fasteners, and damage to the head of the fastener.

The main purpose of the present invention is to provide a multi-clamping point sleeve driver bit, especially a bit design that can substantially eliminate sliding.

The design of the present invention contains several parts. The integral function of these parts can engage the head of the fastener, so that torque can be effectively transmitted between the screwdriver head and the head of the fastener. Traditional boltdrivers may use unnecessary tools and drill holes. The present invention avoids these problems. With the development of electric screwdrivers and electric drills, people have generally used electric tools to apply torque to remove fasteners. The present invention provides a double-head screwdriver head, which can apply a torsion force to a fastener in a clockwise or counterclockwise direction to lock or loosen the fastener. Most screwdrivers have a standard quarter-inch hexagonal gripping end, but also include but are not limited to square, hexagonal, or star-shaped drive ends.

First of all, it should be particularly noted that the illustrations used in this specification are only used to illustrate certain embodiments of the present invention, and the scope of the present invention is not limited by these illustrations.
