[0021] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.
[0022] See Figures 1 to 6 This embodiment discloses a detachable multi-functional anti-slip screw socket combination tool, including a socket head 1. The internal channel of the socket head 1 is divided into an anti-rotation section 2 and an operating section 3 along the axial direction. The anti-rotation section 2 of the internal channel of the socket head 1 has a polygonal cross-sectional shape, such as a square. The operating section 3 of the internal channel of the socket head 1 is a circular channel, and four locking grooves 4 are evenly distributed circumferentially on the operating section 3 of the internal channel of the socket head 1. The length extension direction of the locking grooves 4 is parallel to the axial direction of the socket.
[0023] The tool set also includes a detachable slotted plate assembly, comprising a straight slotted plate 5 and a cross-shaped slotted plate 6. The straight slotted plate 5 is detachably engaged with two corresponding locking slots 4 on the operating section 3 of the socket head 1, and the cross-shaped slotted plate 6 is detachably engaged with four locking slots 4 on the operating section 3 of the socket head 1. The straight slotted plate 5 or the cross-shaped slotted plate 6 can be selected to be used with the socket head 1, depending on the screws that need to be installed or removed.
[0024] The length of the snap-fit groove 4 of the socket head 1 is greater than the length of the straight groove plate 5 or the cross-shaped groove plate 6, so that when the groove plate is inserted to the bottom of the snap-fit groove 4, the end of the socket head 1 protrudes from the end of the groove plate. The part of the socket head 1 that protrudes from the end of the groove plate forms a sleeve section 7. When in use, the sleeve section 7 of the socket head 1 can be sleeved around the screw head that needs to be turned, so that the entire screw head is located inside the socket head 1, which can prevent slippage during the screw tightening process.
[0025] The combination tool is used in conjunction with a screwdriver. The screwdriver includes a screwdriver shaft 8 and a screwdriver head. The screwdriver head includes a base 9 and a head 10. The base 9 is fixedly connected to the screwdriver shaft 8 and is fitted into the anti-rotation section 2 of the internal channel of the socket head 1. The outer end of the head 10 has a cross-shaped slot 11, which can be fitted into a slotted plate 5 and a cross-shaped slot 6 respectively.
[0026] The cross-shaped slot plate 6 has a pointed end 12 at the end furthest from the anti-rotation section 2. The end faces of the four plates of the pointed end 12 are all inclined surfaces with a higher center and a lower outer perimeter, and the end face shape of the four plates of the pointed end 12 is triangular. Designing the contact end between the slot plate and the screw with this type of pointed end 12 facilitates the smooth insertion of the cross-shaped slot plate 6 into the cross-shaped slot of the screw, and can accommodate different types of cross-shaped screws.
[0027] When using this combination tool with a screwdriver, first insert the required slotted plate into the locking slot 4 of the socket head 1. Then, insert the screwdriver tip from one end of the anti-rotation section 2 of the socket head 1 into the internal channel of the socket head 1, so that the base 9 of the screwdriver tip matches the anti-rotation section 2 of the internal channel of the socket head 1, and the cross-shaped notch 11 of the head 10 at the front end of the screwdriver tip fits into the slotted plate inside the operating section 3 of the socket head 1. At this point, the assembly of the socket head 1 and the screwdriver is complete, and the two together form a screw installation tool.
[0028] When installing or removing screws, the socket head 1 of the screw installation tool is fitted around the screw head, and the slotted plate is embedded in the slot of the screw head. Force is applied axially along the socket head 1 and the screwdriver shank 8 is rotated. As the screwdriver shank 8 is inserted deeper, the slotted plate gradually extends and rotates, guiding the screw in or out, thus completing the convenient installation or removal of the screw.
[0029] This combination tool can also be used with ratchet wrenches or other wrenches, simply by designing the working head of the wrench to be the same shape as the screwdriver head mentioned above. It has a wide range of applications and good versatility.
[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
