[0030] When electrical technicians or mechanics inspect and repair equipment, some equipment may have many structural components and limited space, resulting in threaded fasteners being located in narrow and inaccessible areas. In such cases, threaded fastener removal and installation tools are often necessary. These tools are used to install, remove, and adjust threaded fasteners (such as screws and nuts). Depending on the application, the types of tools and their usage methods vary. However, existing tools are bulky, inflexible, and inconvenient for working in confined spaces.

[0031] Based on this, please refer to Figure 1The sleeve 1000 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. The sleeve 1000 allows for the replacement of different connectors according to the disassembly and assembly of different threaded fasteners, and the mounting part 300 can rotate relative to the handheld part 100, enabling flexible operation in confined spaces. The sleeve 1000 can be used as a tool for disassembling and assembling threaded fasteners; any tool with the sleeve 1000 has the same functions as described above, and is not limited thereto.

[0032] The disassembly and assembly tools in this embodiment include a connector and a sleeve 1000. The connector is detachably connected to the mounting part 300 and is used for disassembling and assembling threaded fasteners. The connector is used to tighten or loosen threaded fasteners. The detachable connection between the connector and the mounting part 300 allows operators to select different connectors according to the actual threaded fasteners being disassembled or assembled, making it widely applicable and highly practical. Specifically, the connector in this embodiment is a screwdriver bit or a wrench. The screwdriver bit can be a Phillips head screwdriver bit, a flathead screwdriver bit, an internal hex screwdriver bit, or a Torx screwdriver bit, etc., depending on the actual type of threaded fastener being disassembled or assembled, and is not limited here. The wrench can be an internal hex wrench or an external hex wrench, etc., depending on the actual type of threaded fastener being disassembled or assembled, and is not limited here. The threaded fasteners here are screws, bolts, screws, etc., and are not limited here.

[0033] The aforementioned "detachable connection between the connector and the mounting part 300" specifically refers to the plug-in connection between the connector and the mounting part 300 in this embodiment. This plug-in connection method typically eliminates the need for specialized tools, allowing for quick disassembly for repair, adjustment, or replacement of parts, which is particularly important for equipment requiring frequent maintenance or upgrades. Furthermore, plug-in connections generally do not require complex welding, riveting, or other processing techniques, resulting in lower production and installation costs. In detail, in this embodiment, the mounting part 300 is a hollow cylindrical structure. The inner wall of the mounting part 300 has a recess, and the outer surface of the connector has a protrusion. The protrusion mates with the recess to achieve the plug-in connection between the connector and the mounting part 300. Alternatively, the connector and mounting part 300 can be plugged in by having mounting holes on both the connector and the mounting part 300, with pins inserted into these holes. The connector and mounting part 300 are then plugged in by the pins passing through the mounting holes.

[0034] To ensure a secure connection between the connector and the mounting part 300, the inner wall of the mounting part 300 in this embodiment is provided with an internal thread, and the outer surface of the connector is provided with an external thread, with the external thread engaging with the internal thread. The mounting part 300 and the connector can be connected by thread alone, or by a combination of plug-in and threaded connection, or by a combination of snap-fit ​​and threaded connection, to enhance the tightness of the connection between the connector and the mounting part 300.

[0035] To prevent the connecting rod 200 from rotating relative to the handle 100 during the installation and removal of threaded fasteners, a locking structure is provided for the connecting rod 200 and the handle 100 in this embodiment. After the connecting rod 200 rotates to a suitable angle, the locking structure locks the connecting rod 200 and the handle 100 together, preventing rotation between them. When the angle of the connecting rod 200 needs to be adjusted, the locking is released, allowing the connecting rod 200 to rotate at any angle relative to the handle 100.

[0036] In addition, the connector and the mounting part 300 can be detachably connected. In addition to the plug-in connection, other detachable connection methods such as snap-fit ​​connection and threaded connection can also be used, which are not limited here.

[0037] The following is a detailed description of sleeve 1000.

[0038] Figure 1 This is a schematic diagram of the sleeve 1000 provided in an embodiment of the present utility model, as shown below. Figure 1 As shown, the sleeve 1000 in this embodiment includes a handle 100, a connecting rod 200, and a mounting part 300. The connecting rod 200 is rotatably connected to the handle 100. The mounting part 300 is connected to the end of the connecting rod 200 away from the handle 100; the mounting part 300 is used for detachable connection with a connector for disassembling and assembling threaded fasteners. By rotatably connecting the connecting rod 200 to the handle 100, the connecting rod 200 can rotate relative to the handle 100 according to the actual disassembly and assembly environment, deforming to allow for flexible operation in confined spaces. The mounting part 300 is detachably connected to the connector, allowing different connectors to be installed and replaced on the mounting part 300 depending on the type of threaded fastener being disassembled and assembled. Furthermore, the sleeve 1000 has a simple structure, small size, and is lightweight. In this embodiment, the connecting rod 200 is hinged to the handle 100, and the connecting rod 200 can rotate relative to the handle 100 in any direction. Of course, the connecting rod 200 and the handheld part 100 can also adopt other rotating connection methods. The rotation angle can be determined according to the actual use, and the rotating structure can be designed according to the rotation angle and direction. No limitation is made here.

[0039] To assemble multiple types of connectors simultaneously and to quickly disassemble various threaded fasteners, please refer to [link / reference needed]. Figure 1In this embodiment, there are multiple connecting rods 200 and mounting portions 300. Each connecting rod 200 corresponds to at least one mounting portion 300, and the ends of the multiple connecting rods 200 away from the mounting portions 300 are rotatably connected to the handheld portion 100. In this embodiment, the number of connecting rods 200 and mounting portions 300 is the same, with each connecting rod 200 corresponding to one mounting portion 300. Each connecting rod 200 is hinged to the handheld portion 100 and can rotate in any direction around the hinge point. When it is necessary to extend into a small space, the multiple connecting rods 200 can be retracted toward the handheld portion 100. After the space to be extended into widens, the corresponding connecting rod 200 that can be used to detach or install a specified threaded fastener can be rotated to the angle where it can be detached or installed, and the threaded fastener to be detached or installed can be detached or installed.

[0040] In addition, please see Figure 1 In this embodiment, connecting rods 200 can be provided at both ends of the handheld part 100, so the connecting rods 200 can be rotatably connected to the handheld part 100. Furthermore, multiple connecting rods 200 can be rotatably connected to each end of the handheld part 100. Each connecting rod 200 is detachably connected to at least one mounting part 300. Each mounting part 300 is detachably connected to a type of connector. Of course, two or more mounting parts 300 can also be detachably connected to the same type of connector, depending on the actual use, and are not limited here.

[0041] The aforementioned "mounting part 300 for detachable connection with the connector" specifically refers to the fact that, in this embodiment, the mounting part 300 is a hollow cylindrical structure, and its inner wall is provided with a snap-fit ​​structure. More specifically, in this embodiment, the mounting part 300 is a hollow cylindrical structure, its inner wall has a recess, and the outer surface of the connector has a protrusion. The protrusion and the recess engage to allow the connector to be inserted into the mounting part 300. Alternatively, a slot can be formed on the inner wall of the mounting part 300, and a snap-fit ​​structure engaging with the slot can be provided on the connector; alternatively, a snap-fit ​​structure can be formed on the inner wall of the mounting part 300, and a slot can be formed on the connector, with the snap-fit ​​structure engaging with the slot to achieve a detachable connection between the mounting part 300 and the connector. Of course, the mounting part 300 and the connector can also be connected by a detachable connection method such as insertion or threaded connection. Furthermore, the mounting part 300 and the connector can also be connected by a fixed connection method such as welding, which is not limited here. In this embodiment, the mounting part 300 is a hollow cylindrical shape. Of course, the mounting part 300 can also be designed as a hollow square cylinder or other shapes, depending on the actual assembly joint, and is not limited here.

[0042] Furthermore, the mounting part 300 and the connector can also be connected by threads. Specifically, in this embodiment, the inner wall of the mounting part 300 is provided with threads. A snap-fit ​​structure and threads can be simultaneously provided on the inner wall of the mounting part 300, and the snap-fit ​​connection and threaded connection can be used in conjunction. Of course, threads can also be used in conjunction with other detachable connection methods, which are not limited here.

[0043] To reduce the friction between the inner wall of the mounting portion 300 and the connector, the inner wall of the mounting portion 300 in this embodiment is provided with ball bearings. Multiple ball bearings can be evenly distributed on the inner wall of the mounting portion 300. By providing ball bearings, the contact area between the connector and the mounting portion 300 can be changed from surface contact to point contact. Furthermore, when the connector is inserted into the mounting portion 300, sliding friction can be converted into rolling friction, reducing the friction between the connector and the mounting portion 300 and allowing for better snap-fit ​​or insertion.

[0044] In this embodiment, the "connection between the mounting part 300 and the other end of the connecting rod 200" refers to a connection where the mounting part 300 and the connecting rod 200 can be fixedly connected by welding or other methods, or they can be detachably connected, such as by plugging in. For example, the connecting rod 200 may have a mounting hole, into which the mounting part 300 is inserted. To ensure a tight connection between the connecting rod 200 and the mounting part 300, a snap-fit ​​structure may be provided on the side wall of the connecting rod 200 forming the mounting hole.

[0045] In summary, the sleeve 1000 includes a handle 100, a connecting rod 200, and a mounting part 300. The connecting rod 200 is rotatably connected to the handle 100. The mounting part 300 is connected to the end of the connecting rod 200 away from the handle 100. The mounting part 300 is used for detachable connection with a connector for attaching and detaching threaded fasteners. By rotatably connecting the connecting rod 200 to the handle 100, the connecting rod 200 can rotate relative to the handle 100 according to the actual attachment / removal environment, causing deformation to allow for flexible operation in confined spaces. The mounting part 300 is detachably connected to the connector, allowing different connectors to be installed and replaced on the mounting part 300 depending on the type of threaded fastener being attached or detached. Furthermore, the sleeve 1000 has a simple structure, small size, and is lightweight.
