AI Technical Summary
Existing socket wrenches cannot be used when there is obstructed corner space above the screw, making it impossible to effectively install or remove the screw.
A modular socket wrench was designed, comprising a first connecting rod, a second connecting rod, and a universal joint. The transmission direction is changed through the universal joint, and hexagonal studs are set at both ends of the universal joint to connect the socket. The position of the connecting rod is fixed by a clamping device, enabling assembly and disassembly in corner spaces.
It enables the installation and removal of screws in corner spaces where the screws are covered, and the operation is more effortless and stable.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware tools, specifically a combination socket wrench. Background Technology
[0002] A socket wrench is a common tool used to install and remove external hexagonal flathead screws. For example, utility model application CN202422331131.X discloses a wrench assembly for tightening screws in small spaces, including a long socket and a long lead screw built into the long socket. The lower end of the long lead screw extends beyond the long socket, and its upper end is connected to a socket-linked right-angle wrench. The end of the socket-linked right-angle wrench is connected to a first wrench end. The auxiliary stabilizing component includes a handheld long rod with a second wrench end.
[0003] This utility model is mainly used for screw fastening in small spaces, but it cannot be used when there is an obstruction above the screw and it cannot be directly connected to the screw in a corner space. Utility Model Content
[0004] This utility model provides a combined socket wrench to solve the above-mentioned technical problems.
[0005] A combination socket wrench includes a first connecting rod, a second connecting rod, and a universal joint. The first connecting rod is connected to the universal joint, and the second connecting rod is connected to the universal joint. One end of the first connecting rod is provided with a socket, and one end of the second connecting rod is provided with a rotating handle.
[0006] Furthermore, the universal joint is provided with hexagonal studs at both ends, and the first connecting rod and the second connecting rod are provided with connecting sleeves that match the hexagonal studs.
[0007] Furthermore, the first and second connecting rods are provided with clamping devices, the clamping devices including a cylinder, a connecting plate, a U-shaped base and a wing screw, the cylinder is connected to the connecting plate, the other end of the connecting plate is connected to the U-shaped base, the U-shaped base is provided with a through hole and a nut, the through hole and the nut are concentric, and the wing screw engages with the nut.
[0008] Furthermore, the second connecting rod is provided with a long cylinder.
[0009] Compared to existing technologies, this invention can be used in corner spaces where the screw is covered. By changing the transmission direction through a universal joint, screws can be installed and removed even in corner spaces. By setting hexagonal studs at both ends of the universal joint, and setting connecting sleeves that match the hexagonal studs on the first and second connecting rods, installation in corner spaces is convenient. The clamping device fixes the position of the first and second connecting rods, preventing the universal joint from coming off during use. Attached Figure Description

[0014] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.
[0015] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0017] A combination socket wrench includes a first connecting rod 1, a second connecting rod 2 and a universal joint 3. The first connecting rod 1 is connected to the universal joint 3, and the second connecting rod 2 is connected to the universal joint 3. A socket 4 is provided at one end of the first connecting rod 1, and a rotating handle 5 is provided at one end of the second connecting rod 2.
[0018] In a preferred embodiment, the universal joint 3 is provided with hexagonal studs 6 at both ends, and the first connecting rod 1 and the second connecting rod 2 are provided with connecting sleeves 7 that match the hexagonal studs 6.
[0019] When using, first insert the sleeve 4 of the first connecting rod 1 into the hex screw, then insert the hex stud 6 of the universal joint 3 into the connecting sleeve 7 of the first connecting rod 1, and then install the second connecting rod 2 to complete the installation. Rotate the handle 5 to install and remove the hex screw.
[0020] In a preferred embodiment, the first connecting rod 1 and the second connecting rod 2 are provided with a clamping device 8. The clamping device 8 includes a cylinder 9, a connecting plate 10, a U-shaped base 11 and a wing screw 12. The cylinder 9 is connected to the connecting plate 10, and the other end of the connecting plate 10 is connected to the U-shaped base 11. The U-shaped base 11 is provided with a through hole 13 and a nut 14. The through hole 13 and the nut 14 are concentric, and the wing screw 12 engages with the nut 14.
[0021] This utility model is mainly used in corner spaces where it is impossible to directly insert a long wrench into a hexagonal screw. Therefore, there will be some obstructions above the hexagonal screw. You can find a suitable position to insert the U-shaped base 11 and tighten the wing screw 12 to fix the clamping device 8. In this way, when rotating the handle 5, the first connecting rod 1 and the second connecting rod 2 will not shake, making it more labor-saving.
[0022] As a preferred embodiment, the second connecting rod 2 is provided with a long cylinder 15. When rotating the handle 5, one hand can hold the long cylinder 15 and the other hand can rotate it, which is more convenient.
[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
