[0026] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please refer to the following: Figures 1 to 5 This embodiment provides a sleeve conversion connector, which includes a column 20. The first end of the column 20 extends circumferentially to form a flange edge 10, and the first end of the column 20 has a connecting hole 11 along its axial direction. The cross-sectional shape of the connecting hole 11 is polygonal. The second end of the column 20 serves as an insertion end, and the cross-sectional shape of the second end of the column 20 is also polygonal. The polygonal connecting hole 11 is adapted to the shape of the drive rod or head of the drive tool, and the use of the polygonal connecting hole 11 prevents relative rotation between the two. In addition, the shape of the insertion end is adapted to the shape of the connecting end of the sleeve, and the use of the polygonal insertion end of the column 20 can restrict relative rotation between the two.

[0028] As can be seen, in this embodiment, the sleeve adapter has a flange edge 10 extending circumferentially from the first end of the column 20, and a connecting hole 11 is provided at the first end of the column 20 along its axial direction. The cross-sectional shape of the connecting hole 11 is polygonal. The second end of the column 20 serves as the insertion end, and the cross-sectional shape of the second end of the column 20 is also polygonal. Thus, the head of the driving tool is inserted into the connecting hole 11, and the insertion end of the column 20 is inserted into the sleeve. The driving tool and the sleeve are then connected by the sleeve adapter, allowing the user to quickly tighten and loosen nuts using the driving tool, thereby improving the applicability and convenience of the product and making it more convenient and faster for the user.

[0029] Furthermore, such as Figure 4As shown, the depth of the connecting hole 11 is greater than the thickness of the flange edge 10 and less than the length of the column 20; and / or a limiting hole 110 is provided on at least one side wall of the connecting hole 11. If the connecting hole 11 is too shallow, it cannot effectively transmit torsional force, affecting the use of the adapter; if the connecting hole 11 is too deep, it will affect the strength of the adapter, thereby reducing its service life. The limiting hole 110 is used to limit the adapter when connected to other connecting tools, cooperating with a protrusion on the drive rod of the driving tool to prevent the sleeve adapter from easily slipping off, further increasing the product's stability, practicality, safety, and reliability.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, the flange edge 10 has at least one mounting hole 12, and a magnet 30 is installed in the mounting hole 12. With this configuration, when the sleeve adapter is connected to the sleeve and the driving tool respectively, the magnetic force of the magnet 30 will attract the sleeve adapter to the driving tool, making the connection structure more stable, further increasing the reliability and practicality of the product, and making it easier to use.

[0031] The shape of the flange edge 10 can be circular, square, polygonal, gear-shaped, etc., and this embodiment does not limit its specific shape.

[0032] Specifically, such as Figure 1 As shown, a guide surface 13 is provided on the end face of the flange edge 10 away from the column 20, and the connecting hole 11 is located in the middle of the guide surface 13. This arrangement facilitates the insertion of the drive rod of the driving tool into the connecting hole 11 via the guide surface 13, while also reducing damage to the flange edge 10 when the drive rod of the driving tool is inserted into the connecting hole 11. This further increases the reliability of the product.

[0033] Furthermore, such as Figure 1 and Figure 4 As shown, the guide surface 13 extends in an arc-shaped recess or inclined direction from the outer periphery of the opening of the connecting hole 11 on the flange edge 10 towards the center. The guide surface 13 is simple and easy to implement, allowing the drive rod of the driving tool to be inserted into the connecting hole 11 more smoothly. The insertion structure is quick and convenient, making it easy for users to use. Moreover, this design makes the product more aesthetically pleasing and further enhances its appearance.

[0034] In this example, such as Figure 1As shown in Figure 4, gap grooves 111 are provided at multiple corners of the inner wall of the connecting hole 11, extending along the depth direction of the connecting hole 11. By providing gap grooves 111, the diameter of the connecting hole 11 is better matched to the size of the drive rod of the driving tool, facilitating the smooth insertion of the drive rod into the connecting hole 11. This avoids the drive rod being too large to fit into the connecting hole 11, indirectly increasing the volume of the connecting hole 11 and improving the product's applicability. Simultaneously, it reduces damage to the connecting hole 11 from the sharp edges of the drive rod, further increasing the product's reliability and safety.

[0035] Specifically, such as Figure 2 As shown, the second end of the column 20 has several rounded corners 21 at its apex. This design facilitates the insertion of the adapter into the sleeve while reducing damage to external tools from the adapter's apex corners. This further increases the product's reliability.

[0036] Furthermore, such as Figure 2 As shown, the cross-sectional shape of the second end of the prism 20 is a quadrilateral, and the rounded corner 21 is formed by the smooth transition between the point of tangency of the inscribed circle of the quadrilateral at the second end of the prism 20 and the four edges of the prism 20. This design makes the rounded corner 21 simple and easy to implement, and also makes the product's appearance more beautiful, further improving its aesthetics and popularity.

[0037] Furthermore, such as Figure 3 As shown, the thickness of flange edge 10 is denoted as D, and the length of column 20 is denoted as L, where D / L ≤ 1 / 3. By reducing the proportion occupied by flange edge 10, the space occupied by the conversion joint is reduced, making this utility model applicable to various occasions, further improving the applicability and practicality of the product, and facilitating user use.

[0038] In this embodiment, the cross-sectional shape of the connecting hole 11 is quadrilateral. The quadrilateral cross-sectional shape conforms to the shape of the drive rod of most existing drive tools, further improving the reliability and usability of the product.

[0039] In this embodiment, the sleeve adapter can be designed in different sizes to form a set for sale or use, including at least the following four sizes:

[0040] 3 / 4" (F) - 1" (M)

[0041] 1 / 2" (F) - 3 / 4" (M)

[0042] 1 / 2" (F) - 3 / 8" (M)

[0043] 1 / 4" (F) - 3 / 8" (M)

[0044] It is worth mentioning that among the four sizes of socket adapters mentioned above, the smaller socket adapters can be stacked on top of the larger ones. In this embodiment, when using different sizes of sockets, the corresponding socket adapters can be replaced to match the drive tools. Furthermore, the socket adapters have a simple and compact structure. The smaller socket adapters can be stacked on top of the larger ones for storage. They are small in size, do not take up much space, and are easy to store and carry, making them more convenient and faster for users.

[0045] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0046] The sleeve adapter of this utility model has a flange edge 10 extending circumferentially from the first end of the column 20, and a connecting hole 11 is provided axially at the first end of the column 20. The cross-sectional shape of the connecting hole 11 is polygonal. The second end of the column 20 serves as the insertion end, and the cross-sectional shape of the second end of the column 20 is also polygonal. Thus, the head of the driving tool is inserted into the connecting hole 11, and the insertion end of the column 20 is inserted into the sleeve. The drive tool and the sleeve are connected by the sleeve adapter, which allows the user to quickly tighten and loosen nuts using the drive tool, thereby improving the applicability and convenience of the product and making it more convenient and faster for the user.
