Description

Multi-clamping point sleeve screwdriver head
Technical Field
The present invention relates to a tool for loosening and tightening fasteners, particularly screws and nuts. And more particularly, to an anti-slip multi-directional screwdriver head capable of preventing the screwdriver head from damaging or slipping off a fastener during the process of removing or locking the fastener.
Background
Hexagonal bolts, nuts, screws, and other similar threaded fasteners secure a plurality of parts together by engaging complementary threads (commonly referred to as female threads). The structure of such fasteners generally comprises: a cylindrical shaft portion having external threads, and a head portion at the trailing end of the shaft portion. The external thread engages with a complementary female thread, typically formed by tapping into a hole or nut, to secure the fastener and simultaneously the associated part. The fastener is rotated or driven into the female thread by its head receiving an external torque force. The head is shaped to allow an external tool, such as a wrench, to apply torque to the fastener to rotate the fastener to engage the complementary female threads to some extent. Such fasteners are simple, inexpensive, and very effective and are therefore commonly used in modern society.
One of the common problems with the use of such fasteners is: whether the fastener is male or female, the tool often slides over the head. The reasons for this are likely to be: tool or fastener wear, tool or fastener rust, excessive fastener torquing, head damage of the fastener.
Disclosure of Invention
The present invention relates to a screwdriver head design capable of substantially eliminating sliding. The design of the present invention comprises several parts. The overall action of such portions may engage the head of the fastener, thereby effectively transferring torque between the driver bit and the fastener head. Conventional bolt drivers may use tools and bores that are not otherwise needed. The present invention avoids these problems. With the development of power screwdrivers and drills, it has become common to use power tools to apply torque to remove fasteners. The present invention provides a double-ended driver bit that can apply a torque to a fastener clockwise or counterclockwise to lock or unlock the fastener. Most driver bits have a standard one-quarter inch hex grip end and include, but are not limited to, square, hex, or star shaped drive ends.

Detailed Description
First, it is specifically described that: the drawings used in the present specification are only for the purpose of illustrating certain embodiments of the invention and the scope of the invention is not limited by the drawings.
The present invention relates to a tool attachment, and more particularly to a multi-grip socket driver bit, which is a screwdriver bit or screw driver bit. The present invention can apply a greater torque to the fastener than other similarly sized conventional screwdriver bits without damaging the fastener head or the tool. The efficacy of the present invention is achieved by the engagement structure having a plurality of features that enable the engagement structure to effectively grip the head of the fastener. The present invention is a socket driver head that is compatible with a variety of torque tools, including: conventional electric drills, screwdrivers, socket wrenches, socket drivers that can receive a driver bit, but these torque tools are not limited to the torque tools described above.
Referring to fig. 1, a simplified embodiment of the present invention is shown. In this embodiment, the present invention comprises: at least one screwdriver bit body 1. The screwdriver bit body 1 is a stem which can be combined with a socket fastener, for example: socket screw and socket screw to quickly apply a torque to a socket fastener. The screwdriver bit body 1 further comprises: a plurality of side walls 2, a first base 9, and a second base 10. Generally, the screwdriver bit body 1 is a prismatic body composed of a high strength metal. The plurality of side walls 2 engage the socket fastener to effectively transfer torque from the torque tool to the socket fastener. The first base surface 9 and the second base surface 10 are opposite to each other across the plurality of side walls 2, and the first base surface 9 and the second base surface 10 are perpendicular to the plurality of side walls 2, thereby forming the prismatic screwdriver bit body 1.
Please refer to fig. 3 and fig. 4. Each side wall 2 further comprises: a first side edge 3, a second side edge 4, a side surface 5, and at least one bonding pocket 6. The plurality of side walls 2 radially surround a rotational axis 11 of the screwdriver bit body 1 to create a shape complementary to the socket fastener profile. The number of side walls 2 varies with the shape of the socket fastener to complement the shape of the socket fastener. In one embodiment of the invention the number of side walls 2 is 6, whereas the cross section of the resulting screwdriver bit body 1 is a hexagon. In another embodiment of the invention the number of side walls 2 is 4, whereas the cross section of the resulting screwdriver bit body 1 is a quadrangle.
The side 5 bears against the side wall of the socket fastener, in particular the socket fastener head. The first side edge 3 and the second side edge 4 are opposite to each other across a side face 5. The first side edge 3 and the second side edge 4 form an edge angle of the screwdriver bit body 1 from a top view or a bottom view. The coupling pockets 6 are recessed into the side 5, thereby creating additional gripping points or gripping teeth at the side 5. Additional clamping points are created in the bonding pocket 6 and adjacent side edges, wherein adjacent side edges may be the first side edge 3 or the second side edge 4, in particular the side edge closest to the bonding pocket 6. The bonding pocket 6 extends on the screwdriver bit body 1 from the first base 9 towards the second base 10. And the bonding pocket 6 tapers from the first base surface 9 toward the second base surface 10. Thus, the additional clamping points extend in the longitudinal direction of the screwdriver bit body 1, so that the maximum clamping and combining force can be provided between the combining hole 6 and the socket fastener. In a preferred embodiment, the coupling pocket 6 has a semicircular cross section. The semicircular cross section allows the screwdriver bit body 1 to have no or few high stress points, thereby increasing the overall tool life. In other embodiments of the invention, the bonding pocket 6 may have other shaped cross-sections. Other shapes of cross-sections include, but are not limited to: half square, half rectangle, and half oval cross sections.
In a preferred embodiment of the invention, the coupling pockets 6 are arranged to transmit torque most effectively, in particular the coupling pockets 6 are located at a first distance 12 from the first side edge 3. At the same time, the coupling pocket 6 is located at a second distance 13 from the second side edge 4. The transmission of torque is most efficient when the ratio of the widths of the first distance 12, the second distance 13, and the bonding pocket 6 is 1:5:4.
The ratio of the first distance 12, the second distance 13, and the width 8 of the bonding pocket 6 may be varied to achieve a clockwise or counterclockwise design. Fig. 1 shows an embodiment of the clockwise driver bit of the present invention. In this embodiment, the first distance 12 is less than the second distance 13. The present invention designs for gripping and applying torque to socket fasteners in a clockwise direction can be achieved when the ratio of the first distance 12, the second distance 13, and the width of the bonding pocket 6 is 1:5:4. This design is used to screw in or secure a socket fastener. In another embodiment, the present invention is designed as a counter-clockwise screwdriver bit. In this embodiment, the first distance 12 is greater than the second distance 13. The design of the present invention to clamp and apply torque to socket fasteners in a counter-clockwise direction is achieved when the ratio of the first distance 12, the second distance 13, and the width of the bonding pocket 6 is 5:1:4. Such a design is used to loosen or remove socket fasteners.
Please refer to fig. 5. In one embodiment, the present invention further includes a plurality of intermittent sidewalls 18. Each intermittent sidewall 18 is a flat surface that functions like a conventional screwdriver bit design in conjunction with a socket fastener. The plurality of intermittent side walls 18 radially surround the rotation shaft 11 of the screwdriver bit body 1. A plurality of intermittent side walls 18 are interposed between the plurality of side walls 2. Thus, the plurality of intermittent side walls 18 and the plurality of side walls 2 are alternately distributed in the radial direction of the screwdriver bit body 1.
