New description: [New technical field] This creative department is about the technical field of the starter structure, especially a kind of 2 easy to use « screwing elements and secret application materials Wei Zhizizi job improvement [previous technology] Referring to the figure - the figure indicates that the current common starter head structure mainly has a connection section 10 at the center, and two action sections u at both ends are connected to the connection k 10 . The joint portion 10 is a rod having a hexagonal cross section, and can be inserted into a socket (not shown) of a power tool (such as a pneumatic tool, an electric tool, etc.) or a sleeve wrench. . The connecting section 1G has two annular grooves 12 near the two acting sections u, so that the positioning device in the socket can be quickly buckled or released to facilitate the replacement of the screwdriver head. The action section 1H is a rod having a circular cross section, and has a tapered portion 13 at the front end. The circumferential surface of the ridge 11 has four working grooves 14 extending axially to the end surface, and the working groove 14 has a V-shaped cross section, and the twist thereof is gradually reduced from the end portion to the inner surface. Four working ribs 15 are formed between the four working slots to form a cross-shaped groove of the head of a screwing member (such as a bolt or a screw) for driving the snail The piece rotates to perform the work of tightening or unscrewing. Thus, when the working rib 15 of the action section 11 is inserted into the cross groove of the screw member to be rotated, the user needs to use a large force to push the screwdriver head down: press 'to assist the push The advancement screw of the fitting has a problem that it is not easy to lock the screwing element and is not easy to apply force. With this in mind, this creator is developing and designing this creation by focusing on the above issues and in-depth conceiving, and actively researching and improving the trial. [New content] The main purpose of this creation is to provide a screwdriver head structure improver with a flank locking screw element and easy to apply force. Specifically, the improvement of the screwdriver head structure described in the present application includes a connecting section and two functions. The splicing section of the towel has a polygonal shape (such as a hexagonal shape). The rod body has two ring grooves near the two ends, and the two action segments are respectively extended from the two ends of the material connection section. Shaped rod body. The front end of the action section has a tapered portion, and the (four) plane has four right spiral grooves extending to the end surface with a small spiral angle. The end surface of the cone 4 is a tapered surface of a larger angle. The right spiral groove has a V-shaped cross section and the depth thereof is gradually reduced from the end portion to the circumferential surface, so that the four right micro grooves are connected to the four right spiral ribs of the cross shape. A cross recess that engages the head of a screw.如此 Thus, when the right spiral rib of the action section is inserted into the cross recess of the screw and rotates clockwise, the spiral view of the right rib will produce the component force of the forward groove. Thereby, the force component can assist in pushing the screw forward screw, so it has the function of easy to lock the screwing element and easy to apply force. [Embodiment] Please refer to the second to eighth figures. The improvement of the screwdriver head structure shown in the present application includes a connecting section 20 and two acting sections 30, wherein: the connecting section 20 has a polygonal cross section. The rod (such as a hexagon) can be inserted into a power tool (such as a pneumatic tool, a power tool, etc.) or a socket wrench (not shown). The connecting section 2 has two annular grooves 21 near the ends and a convex portion 22 at the center. The two-ring groove 21 can be quickly inserted or released by the positioning device of the S-mounting portion to facilitate the replacement of the screwdriver head. Both sides of the rounded portion 22 have symmetrical neck portions 23, and the neck portion 23 has a depth and a width larger than the ring groove 21. The two action segments 30 extend from the ends of the connecting segment 20, respectively, and have the same shape. The section 3G riding surface shape (four) has a cone portion 3 at the front end and the circumference has four right spiral grooves extending from the small angle to the end surface, and the spiral angle /3 is 3 degrees. The angle between the circumferential surface of the tapered portion 31 and the central axis s of the active portion 3 () is 26. 5 degrees 'the tapered surface 33 and the same The working angle α of the vertical line V of the central axis S of the side section 3G is 17 to 19 degrees. The right spiral groove 32 has a v-shaped cross section and its depth is gradually reduced from the end portion to the circumferential surface, so that the four right-hand ribs are axially connected between the four right-hand slots 32. It can be sprinkled into the cross recess 42 of the head 41 of the screw member. The groove walls on both sides of the right spiral groove 32 have a slope % which is inferior to the ridge and a slope 36 which extends from the elevation π to the phase M434657 and whose angle r is greater than 9G degrees, and the clip is preferably (10) degrees. / When the right helical rib 34 of the active segment 30 of the present invention is inserted into the ten slot 42 of the screw member 40 and rotated clockwise, the spiral sidewall of the right helical rib % will be generated for the slot wall of the cross recess 42 - The component force that is pushed forward, by which the force component can assist the pushing screw 4G to advance the screw lock, so that it can have the effect of easily locking the screwing element and being easy to apply force. In the present creation, one of the two action segments 3 of the screwdriver head, one of which may have the above-mentioned four right-handed _ 34, and the other is a --shaped head, which is shaped The head is a common starter structure and will not be further described. In summary, since the creation has the above advantages and practical value, and there is no similar product publication in the similar products, the application requirements of the new patent have been met.
