Description

Technical Field

[0001] This utility model relates to the field of wrench technology, specifically a multi-functional wrench. Background Technology

[0002] Wrenches are frequently used tools in the process of mechanical manufacturing, assembly and maintenance. In mechanical maintenance operations, the internal space of decoction machines and packaging machines is narrow, and the operating space of traditional wrenches is limited, making it difficult to flexibly tighten or loosen nuts or bolts in special positions. Conventional wrenches cannot reach into narrow gaps to work, making it difficult to disassemble parts in narrow spaces, which makes it difficult to meet diverse maintenance needs and makes maintenance work cumbersome and time-consuming. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-functional wrench that has the advantages of being multifunctional and easy to disassemble in narrow spaces.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional wrench, including a threaded rod, a secondary nut is threadedly fitted onto the outer side of the left end of the threaded rod, a main screw nut is threadedly fitted onto the right side of the secondary nut, a threaded sleeve is threadedly fitted onto the outer side of the right end of the threaded rod, an adjusting screw is threadedly connected to the inner side of the threaded sleeve, and a rotating handle is fixedly installed at the middle of the right end of the adjusting screw.

[0005] As a preferred embodiment, a connecting rod is welded to the outside of the main screw nut, and a rotating disk is welded to the right end of the connecting rod. The rotating disk is fitted onto the outside of the threaded sleeve and rotated during installation.

[0006] As a preferred embodiment, an adjusting nut is threaded onto the left end of the threaded rod, located between the secondary nut and the main screw nut, and the right side of the adjusting nut is flat.

[0007] As a preferred embodiment, a fastening nut is fitted onto the external thread of the right end of the adjusting screw, and the left end of the fastening nut is fastened to the right end of the threaded sleeve.

[0008] As a preferred embodiment, the main screw nut, rotating disk, and connecting rod are designed as a single unit, with the rotating disk rotating relative to the threaded sleeve.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model adopts a threaded sleeve and threaded connection method, which can effectively prevent the loosening of the components during the use of the wrench, ensuring the stability of the wrench when tightening or loosening nuts and bolts, reducing operational errors and safety hazards caused by loose components. The components cooperate with each other to form an organic whole. The threaded rod, as the core component, provides a foundation for support and connection of other components. It can disassemble parts in narrow spaces and can better grip and disassemble screws. The structure of this wrench is similar to that of a pipe wrench, which can be operated flexibly in narrow spaces and can effectively reach in to solve difficult disassembly problems.

[0011] 2. This utility model can achieve more precise adjustment by adjusting the nut.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example 1:

[0019] Please see Figure 1 As shown, this utility model provides a multi-functional wrench, including a threaded rod 1, a secondary nut 2 is threadedly sleeved on the outer side of the left end of the threaded rod 1, a main screw nut 3 is threadedly sleeved on the right side of the secondary nut 2, a threaded sleeve 5 is threadedly sleeved on the outer side of the right end of the threaded rod 1, an adjusting screw 10 is threadedly connected to the inner side of the threaded sleeve 5, and a rotating handle 9 is fixedly installed in the middle of the right end of the adjusting screw 10.

[0020] This technical solution adopts a threaded sleeve and threaded connection method, which can effectively prevent the loosening of various components during the use of the wrench, ensuring the stability of the wrench when tightening or loosening nuts and bolts, reducing operational errors and safety hazards caused by loose components. The various components cooperate with each other to form an organic whole. The threaded rod 1, as the core component, provides a foundation for support and connection of other components. It can disassemble parts in narrow spaces and can better grip and disassemble screws. The structure of this wrench is similar to that of a pipe wrench, which can be operated flexibly in narrow spaces and can effectively reach in to solve difficult disassembly problems.

[0021] Example 2:

[0022] Based on Embodiment 1, this utility model is as follows: Figure 2 As shown, a connecting rod 7 is welded to the outside of the main screw nut 3, and a rotating disk 6 is welded to the right end of the connecting rod 7. The rotating disk 6 is sleeved on the outside of the threaded sleeve 5 and rotated.

[0023] Adopting such Figure 1 The technical solution shown allows the operator to operate the main screw nut 3 by rotating it to adjust the working size of the wrench. The operator can hold the edge of the rotating disc 6. According to the lever principle, a larger turning radius allows the operator to drive the main screw nut 3 to rotate with less force, thereby reducing the force required for operation. The design of the rotating disc 6 allows the operator to operate it from different angles. In situations where space is limited or the operating position is restricted, the operator can choose the appropriate angle to hold the rotating disc 6 to rotate the main screw nut 3, without being limited to the traditional wrench operation method, which greatly improves the flexibility and adaptability of operation.

[0024] Secondly, in the technical solution, an adjusting nut 4 is threadedly connected to the left end of the threaded rod 1 between the auxiliary nut 2 and the main screw nut 3, and the right side of the adjusting nut 4 is flat; a fastening nut 8 is threadedly connected to the external thread of the right end of the adjusting screw 10, and the left end of the fastening nut 8 is fastened to the right end of the threaded sleeve 5.

[0025] Its adoption is as follows Figure 1The technical solution shown allows for more precise adjustment of the adjusting nut 4. After the secondary nut 2 and the main screw nut 3 have been initially adjusted over a wide range, fine adjustments can be made by rotating the adjusting nut 4. Its flat design on the right side increases the friction with the contacting parts, making the adjustment process more stable and effectively preventing loosening or slippage during the adjustment process.

[0026] Example 3:

[0027] This utility model is as follows Figures 1-3 As shown, the main screw nut 3, rotating disk 6 and connecting rod 7 are designed as a single unit, with the rotating disk 6 rotating relative to the threaded sleeve 5.

[0028] By adopting the above technical solution, the integrated design eliminates the weak points that may exist when connecting multiple components. Compared with welding or other connection methods, the integrated structure can better withstand torque and external force. Under frequent use or when subjected to large forces, it is not easy for components to loosen or break.

[0029] The working principle of this utility model is as follows: By rotating the rotating handle 9, the adjusting screw 10 is driven to rotate. Since the adjusting screw 10 and the threaded sleeve 5 are threadedly connected, according to the principle of thread transmission, the rotation of the adjusting screw 10 will cause the threaded sleeve 5 to move along the axial direction of the threaded rod 1. In this way, the overall length and opening size of the wrench can be adjusted within a large range. The integrated main screw nut 3, rotating disc 6 and connecting rod 7 can be rotated by rotating the rotating disc 6 to drive the main screw nut 3 to rotate. When the main screw nut 3 rotates on the threaded rod 1, it will move along the axial direction of the threaded rod 1, thereby further fine-tuning the opening size of the wrench. After adjusting the position of the threaded sleeve 5, tightening the locking nut 8 can firmly fix the adjusting screw 10 and the threaded sleeve 5 together. After adjusting the size of the entire wrench, tightening the auxiliary nut 2 can further lock the position of the main screw nut 3 and the adjusting nut 4, preventing them from shifting during use and ensuring that the opening size of the wrench remains stable during operation.
