Description

Technical Field

[0001] The utility model relates to the technical field of manual tools, in particular to an adapter sleeve for a ratchet double-purpose wrench, aiming to solve the operation problem when working in the narrow space of the ratchet double-purpose wrench and improve the flexibility and convenience of tool use. Background Technique

[0002] A ratchet double-purpose wrench is a manual tool, and its design combines a ratchet mechanism, allowing users to switch the tightening or loosening state of bolts or nuts by reversing the direction of the wrench without removing the wrench. This kind of wrench usually has a compact structure and high efficient torque transmission ability, making it widely used in various repair and installation works.

[0003] At present, the ratchet double-purpose wrenches on the market usually consist of a ratchet head and a wrench handle, and the ratchet head and the wrench handle are of an integral structure. This structure makes the ratchet double-purpose wrench perform well when operating in a large space, but in a narrow space or special environment, due to the limitations of the wrench size and application method, it is often difficult to operate flexibly or even impossible to complete the work. Content of the Utility Model

[0004] In view of the existing deficiencies, the utility model provides an adapter sleeve for a ratchet double-purpose wrench. This sleeve can be used in cooperation with the ratchet double-purpose wrench to increase the applicable range of the ratchet double-purpose wrench and realize flexible operation in a narrow space.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] An adapter sleeve for a ratchet double-purpose wrench includes a sleeve and a driving end. A polygonal counterbore adapted to bolts and nuts is provided inside the left end of the sleeve. A driving end with a hexagonal structure is fixedly provided at the right end of the sleeve. A counterbore is provided on the outer side surface of the driving end, a compression spring is assembled inside the counterbore, a steel ball is pressed on the upper end of the compression spring, and the steel ball is embedded in the counterbore.

[0007] Further, an inclined surface inclined to the left end is provided on the left side of the circumferential surface of the sleeve, and the surface of the left half of the sleeve is of a conical structure.

[0008] Further, the outer edge of the driving end is all rounded.

[0009] Further, the sleeve and the driving end are of an integral structure.

[0010] Further, the longitudinal width of the driving end is less than the diameter length of the sleeve, and the internal width of the polygonal counterbore is the same as the longitudinal width of the driving end.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model can be used in cooperation with a ratchet combination wrench through the arranged sleeve and driving end, which increases the applicable range of the ratchet combination wrench, realizes flexible operation in a narrow space, and improves the operation flexibility.

[0013] 2. The utility model constitutes a limiting structure through the arranged steel balls and compression springs. During use, the steel balls can be pressed against the inner wall of the ratchet head, and the limiting and fixing of the sleeve are realized by the reverse elastic force of the compression springs, ensuring the stable connection between the sleeve and the ratchet head.

[0014] 3. The outer edges of the utility model are all rounded. Through the rounding treatment, the driving end can better adapt to the ratchet head of the ratchet combination wrench, facilitating the driving end to be inserted into the ratchet head of the ratchet combination wrench, facilitating the installation and disassembly of the sleeve. At the same time, the rounded edges reduce the friction contact area with the ratchet head and reduce the wear rate. Description of the Drawings

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment:

[0024] Such as Figures 1 to 6As shown in the figure, a conversion socket for a ratchet double - purpose wrench includes a socket 1 and a driving end 2. Inside the left end of the socket 1, a polygonal counterbore 4 adapted to bolts and nuts is provided. At the right end of the socket 1, a driving end 2 with a hexagonal structure is fixedly installed. A counterbore 5 is provided on the outer side surface of the driving end 2. A compression spring 6 is assembled inside the counterbore 5. A steel ball 3 is pressed on the upper end of the compression spring 6, and the steel ball 3 is embedded in the counterbore 5. This design solves the problem that the ratchet head and the wrench handle on the existing ratchet double - purpose wrench are of an integral structure, resulting in difficulties in flexible operation or even inability to complete work in narrow spaces or special environments due to the limitations of the wrench size and application method.

[0025] In this embodiment, the left side of the circumferential surface of the socket 1 is provided with an inclined surface inclined to the left end, and the surface of the left half of the socket 1 is of a conical structure. This design helps to operate in narrow spaces or special environments, making it easier for the socket 1 to enter narrow spaces and improving the convenience of operation.

[0026] In this embodiment, the outer edges of the driving end 2 are all rounded. The rounding treatment of the outer edges of the driving end 2 is not only beautiful but also can reduce stress concentration and wear that may occur during use. Through the rounding treatment, the driving end 2 can better adapt to the ratchet head of the ratchet double - purpose wrench, facilitating the driving end 2 to be inserted into the ratchet head of the ratchet double - purpose wrench for the installation and disassembly of the socket 1. At the same time, the rounded edges reduce the friction contact area with the ratchet head and lower the wear rate.

[0027] In this embodiment, the socket 1 and the driving end 2 are of an integral structure, enhancing the overall strength and stability. The integral design also simplifies the manufacturing process, reduces production costs, and increases the service life of the conversion socket 1.

[0028] In this embodiment, the longitudinal width of the driving end 2 is smaller than the diameter length of the socket 1, and the internal width of the polygonal counterbore 4 is the same as the longitudinal width of the driving end 2. This design facilitates the driving end 2 to be inserted into a ratchet head of a corresponding size and enables the polygonal counterbore 4 to accommodate bolts and nuts of a corresponding size, maintaining good cooperation with the driving end 2.

[0029] The working principle of the conversion socket 1 for the ratchet double - purpose wrench: When in use, insert the driving end 2 of the socket 1 into the ratchet head of the ratchet double - purpose wrench. During this process, the steel ball 3 contacts the inner wall of the ratchet head and is pressed into the counterbore 5. When the driving end 2 is installed in place, the steel ball 3 is fixed on the inner wall of the ratchet head under the reverse elastic force of the compression spring 6, realizing the fixation of the socket 1. By inserting the driving end 2 of the socket 1 into the ratchet double - purpose wrench in different directions, the direction of the ratchet function of the socket 1 can be adjusted.

[0030] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
