Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial tools, specifically to wrench components. Background Technology
[0002] In modern industrial manufacturing and machinery maintenance, wrenches are widely used as a fundamental and crucial tool. From precision assembly in automobile manufacturing to routine maintenance of large machinery, wrenches play an indispensable role. With the continuous advancement of industrial technology, the demands for wrench performance, functional versatility, and ease of operation are constantly increasing, prompting continuous innovation and improvement in related technologies to meet the complex and ever-changing needs of production and maintenance.
[0003] Currently, there are various types of wrenches on the market, such as open-end wrenches, box wrenches, and socket wrenches. These wrenches each have their advantages in their respective applications, satisfying common parts disassembly and assembly tasks. However, most are only suitable for parts of specific sizes, lacking versatility. Furthermore, they are often ineffective when dealing with parts of unusual shapes or sizes, failing to meet diverse work requirements.
[0004] Taking a common open-end wrench as an example, when using it, first align the open end with the nut or bolt of the part, and then rotate the wrench to generate torque using the lever principle, causing the nut or bolt to rotate, thereby achieving the disassembly or installation of the part. The operation process is relatively simple and direct.
[0005] Existing wrenches lack effective adjustment and adaptation mechanisms when dealing with parts of different sizes and shapes. When encountering parts of special dimensions, ordinary wrenches cannot provide precise clamping and are prone to slippage, which not only affects work efficiency but may also damage the parts. Utility Model Content
[0006] Therefore, the purpose of this utility model is to provide a wrench to solve the technical problems of uneven sample processing, inconvenient operation, poor accuracy and low efficiency in the prior art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a wrench assembly, comprising a wrench assembly body, characterized in that: a wrench hole is provided on the wrench assembly body, a wrench handle is provided at the bottom of the wrench assembly body, an installation groove is provided on the wrench handle, a rotating component is rotatably disposed in the installation groove, a limit rod is provided on one side of the rotating component, a slot is provided on the inner wall of the wrench hole, and a top plate is provided in the slot.
[0008] By adopting the above technical solution, the limiting rod is rotated by the rotating component, and the inner diameter of the wrench is controlled by the top plate, thereby adjusting the wrench according to different part sizes.
[0009] The present invention is further configured such that a cylinder is provided on the side of the handle near the limiting rod, and a push rod is slidably provided on the end of the cylinder near the limiting rod.
[0010] By adopting the above technical solution, the top plate is ejected by a cylinder, and then different parts are processed.
[0011] The present invention is further configured such that an air supply pipe is provided inside the handle in conjunction with a cylinder, the air supply pipe extends into the mounting groove, and a top cylinder is provided inside the mounting groove in conjunction with the air supply pipe.
[0012] By adopting the above technical solution, the top plate is controlled to process the parts when the user presses the gas pipe.
[0013] The present invention is further configured such that the top cylinder is connected to the top plate.
[0014] By adopting the above technical solution, the top plate is pushed out by the top cylinder, thereby clamping the parts.
[0015] In summary, the present invention has the following main advantages:
[0016] This utility model uses a limit rod to press and push the top plate out of the top cylinder to clamp the parts, and the inner diameter of the wrench can be adjusted according to the size of different parts. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0022] The embodiments of this utility model will be described below based on its overall structure.
[0023] Wrench parts, such as Figure 1-3As shown, the device includes a wrench body 1 with a wrench hole 7 and a handle 2 at the bottom. The handle 2 has a mounting groove 11, and a rotating component 3 is rotatably mounted in the mounting groove 11. A limit rod 4 is provided on one side of the rotating component 3. A slot 9 is provided on the inner wall of the wrench hole 7, and a top plate 8 is provided in the slot 9. In actual use, the wrench hole 7 is aligned with the part for installation. At the same time, by rotating the handle 2, the wrench body 1 is rotated, which in turn rotates the wrench hole 7 and the part, thereby enabling the disassembly and installation of the part.
[0024] Based on the above structure, a cylinder 6 is provided on the side of the handle 2 near the limiting rod 4. A push rod 5 is slidably provided at the end of the cylinder 6 near the limiting rod 4. An air supply pipe 12 is provided inside the handle 2 in conjunction with the cylinder 6. The air supply pipe 12 extends into the mounting groove 11. A top cylinder 10 is provided inside the mounting groove 11 in conjunction with the air supply pipe 12. The top cylinder 10 is connected to the top plate 8. With this arrangement, in actual use, pressing the limiting rod 4 moves the push rod 5, thereby squeezing the cylinder 6. The gas inside the cylinder 6 is compressed and delivered to the top cylinder 10 through the air supply pipe 12, thereby pushing out the top plate 8 and clamping the parts in the wrench hole 7. In actual use, after aligning the wrench hole 7 with the parts for installation, pressing the limiting rod 4 will push out the top plate 8. According to different usage requirements, the wrench angle can be controlled to clamp and rotate different parts.
