Description

Technical Field

[0001] This utility model relates to the field of screwdrivers, specifically a multi-functional folding combination screwdriver. Background Technology

[0002] Screwdrivers are an extremely common and indispensable hand tool in daily life and various industrial production and maintenance scenarios. However, traditional screwdrivers generally suffer from limited functionality; a screwdriver typically can only be equipped with one specific type of bit, such as slotted or Phillips head. This means that when dealing with different types of screws, users need to carry multiple screwdrivers with different bit types, which is extremely inconvenient.

[0003] Meanwhile, traditional screwdrivers also have significant shortcomings in terms of storage and portability. Multiple screwdrivers not only take up considerable space and are easily scattered and lost during storage, but also, when quick bit changes are needed for different screws, the process of finding the appropriate screwdriver often wastes a lot of time, reducing work efficiency. Furthermore, the fixed structure of traditional screwdrivers prevents them from folding, which greatly limits their use in scenarios where tool portability is crucial, such as outdoor repairs and work in confined spaces. Therefore, we have proposed a multi-functional folding combination screwdriver. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-functional folding combination screwdriver, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a multi-functional folding combination screwdriver, including a storage shell, a strip-shaped through groove in the middle of the storage shell, a rotating shaft rotatably mounted inside the strip-shaped through groove, a foldable storage shaft fixedly mounted on the rotating shaft, a detachable cutting head at the end of the foldable storage shaft, and a U-shaped receiving groove on the storage shell.

[0006] Preferably, the interior of the receiving groove has multiple sets of polygonal receiving grooves at equal intervals, and each polygonal receiving groove can accommodate a detachable cutting head.

[0007] Preferably, the receiving groove is U-shaped, and the inside of the receiving groove is hinged to a hinged cover plate.

[0008] Preferably, a fixing block is fixedly installed inside the receiving groove, a magnet is embedded inside the fixing block, and a protrusion that can be attracted by the magnet is fixedly installed on the hinged cover plate at the position corresponding to the magnet.

[0009] Preferably, the end of the foldable storage shaft is integrally formed with a polygonal protrusion insertion part, and a magnet is embedded at the end of the polygonal protrusion insertion part.

[0010] Preferably, the detachable blade includes a sleeve for fitting onto the second magnet, the end of which is integrally formed with the blade.

[0011] Compared with the prior art, this utility model provides a multi-functional folding combination screwdriver, which has the following beneficial effects:

[0012] Versatile Functionality: This combination screwdriver comes with various types of screwdriver bits, such as Phillips head and flathead. By detachably mounting different bits to the end of the foldable storage shaft, it can meet a variety of screw-related needs, avoiding the hassle of carrying multiple single-function screwdrivers. One combination screwdriver can handle complex and diverse work scenarios.

[0013] Convenient storage: The outer casing has a U-shaped storage slot, and the interior has multiple sets of polygonal storage slots at equal intervals, which can be used to store different blades in categories. The hinged cover can cover the storage slots to prevent the blades from being lost or getting dusty. The foldable storage shaft can be rotated and folded, which greatly saves storage space and makes it easy to carry and store. Whether for daily home use or professional work, it can be easily stored and carried.

[0014] Stable operation: The polygonal protrusion at the end of the foldable storage shaft effectively prevents the cutter head from rotating during use, ensuring stable operation. At the same time, the magnet embedded at the end of the polygonal protrusion can attract the cutter head sleeve, further enhancing the stability of the connection between the cutter head and the foldable storage shaft, preventing the cutter head from falling off during use, and improving work efficiency and safety.

[0015] Simple to operate: When using, users only need to take out the adapter blade from the polygonal receiving slot, rotate the foldable storage shaft into a straight line and install the blade; when storing, simply reverse the operation. The operation steps are simple and easy to understand, and even non-professionals can easily get started. Attached Figure Description
