New description: [New technical field] This creation is about a screwdriver structure used to drive a star screw. In particular, the present invention relates to a driver structure having a spherical drive head for angular insertion into a screw hole of a star screw. [Prior Art] There are many tools in the conventional technology for driving a screwdriver with a star-shaped screw. In order to insert the inner screw hole of the rotating screw at an oblique angle, the plurality of rods are connected by a joint and then bent and bent to drive the star. Screw. For example, in the patent application No. 324313, a driving portion of a spherical curved surface formed by tangential cutting of a plurality of circular arcs can be tilted into the inner star-shaped screw by a plurality of leaf-shaped circular arc-shaped driving portions. The circular arc surface formed by the leaf lobes is a circular-circle-shaped lobes formed by tangential cutting of two to three circular curved surfaces, and the moving portion cannot be extended due to the processing problem of the machine, so the driving portion can only have With a circular arc shape with a small inclination angle, the lobes of the driving portion extend to the constricted neck to form a continuous arc shape, and the maximum diameter of the working end of the driving portion specified by the international standard is slightly tired, and the screw hole of the driving portion The direct control 'so the structure exposed by the product on the surface and the existing market, the special-purpose tilting screwdriver of the zhizhi screw can be used for the working end of the driving part. The maximum outer diameter of the working section is circular, which cannot be used in the screwdriver. When the screw hole of the star screw is inserted in a tilted state, it is driven by the snap hole, so that it is easy to slip off and the star screw cannot be smoothly rotated. There are 4 £ here's the author's careful experiment and research, especially for the conception and improvement of the 3 1V1442235 substructure, and the perseverance of the creative spirit. After many trials and experiments, 'finally completed this creation. And proposed a new patent application in this case. [New content] The main purpose of this creation is to provide a driver structure improvement, which is mainly a circular arc-shaped driving portion formed by a plurality of leaf blades. The driving portion is convex arc-shaped, and the constricted neck is concave arc-shaped. Forming an angle with the conical neck arc shape at the maximum diameter of the working end, the driving portion is surrounded by a plurality of convex arc lobes of a large inclination angle, and is formed by a maximum outer diameter of the working section Extending to the front end of the long handle is a constricted neck' to insert a screw hole of the star screw at a large inclination angle, and then rotating the star screw, the modified conventional screwdriver cannot be inserted into the screw hole of the star screw at a large inclination angle. Miscellaneous, providing the advantages of structure and operation JL. The important feature of this creation is that it can be tilted at a large angle and inserted into the screw hole of the star screw to achieve the bite rotation star screw. In combination with the above features, another feature of the present invention is that the lobes of the driving portion can be up to the front end of the neck, and the planting is thin only in the working section of the screwdriver. These and other features of this creation are provided as a type of screwdriver structure, mainly by inserting a star screw screw hole at a slight oblique angle and then rotating the screw. The star screw includes a TORX screw and an XZN screw. The starter structure of the present invention comprises: a long handle portion, a constricted neck portion and a driving portion. The driving portion extends in a convex arc shape to a maximum outer diameter of the working portion, and a concave arc is formed at a maximum outer diameter of the working portion. Extending to the front end of the long handle is a constricted neck, 1 4
