Description

Technical Field

[0001] The utility model belongs to the technical field of hardware, and particularly relates to a portable wrench with a foldable handle. Background Art

[0002] In daily life and work, a wrench is a commonly used hardware tool for tightening or loosening bolts and nuts. However, there are some inconveniences in the use of traditional wrenches, especially when it comes to carrying and storing them. The handle of a traditional wrench is usually fixed and cannot be folded, resulting in a large occupied space and inconvenience for carrying around. In addition, when using a wrench in a poorly lit environment, additional lighting equipment is often required to clearly see the working area for accurate operation.

[0003] The existing adjustable wrench (publication number: CN208051785U) generally has the following problems in use:

[0004] 1. The handle cannot be folded, which is inconvenient for carrying: Inconvenient to carry: The handle of a traditional wrench is fixed, with a large volume and cannot be folded, occupying more space when carrying and not being easy to put into toolboxes, backpacks, etc. This is a trouble for maintenance personnel who need to carry tools frequently when going out, and they may need a larger and heavier toolbox, increasing the carrying burden. Inconvenient to store: In limited storage space, it is not easy to find a suitable storage position for a wrench with a fixed handle, and additional storage space may be required. This not only wastes space but also may cause chaos in the placement of other tools in the toolbox, increasing the difficulty of finding and using other tools. Therefore, there is an urgent need for a portable wrench with a foldable handle.

[0005] 2. It is inconvenient to operate in a poorly lit environment: Inaccurate operation: In insufficient light, it is difficult to clearly see the position and state of the bolt or nut, which may cause the wrench to fail to correctly align with the bolt head, resulting in inaccurate operation. This may lead to the bolt or nut not being fully tightened or loosened, affecting the stability and safety of the connected components. Damaging tools and components: Due to unclear vision, the user may mistakenly place the wrench in the wrong position or angle, causing the wrench to slip or damage the bolt head. Frequent occurrence of this situation will not only damage the wrench and the bolt but also may damage other surrounding components, increasing the maintenance cost. Therefore, there is an urgent need for a portable wrench that is convenient to use in a poorly lit environment.

[0006] 3. The wrench cannot handle the situation where the operating space is relatively narrow: Difficult operation: In a narrow space, it is impossible to use a traditional wrench for effective operation. Due to the length of the wrench and the design of the fixed handle, the operating space may be limited, making it difficult for the user to apply enough force to tighten or loosen bolts and nuts. Extended working hours: In a narrow space, due to the inconvenient operation, it may take longer to complete simple tasks. This not only reduces work efficiency but also may cause delays in the progress of the entire project, especially in cases where time is tight. Therefore, there is an urgent need for a portable wrench that can adjust the angle of the wrench head to cope with narrow environments. Summary of the Invention

[0007] The main purpose of the present invention is to provide a portable wrench with a foldable handle, which can effectively solve the problems in the background technology.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is: A portable wrench with a foldable handle, including a wrench handle. A rotating shaft is provided at the end of the wrench handle. A wrench folding handle is provided on the right side surface of the wrench handle. A folding handle hook is provided at the lower right end of the wrench folding handle. A wrench handle connection structure is provided at the upper end of the wrench handle. The wrench handle connection structure is connected to a wrench head connection module. A wrench head is provided at the upper end of the wrench head connection module. A lighting module is provided at the upper end of the wrench head. A lighting lamp is provided on the lower end surface of the lighting module. A lighting device switch is provided on the back of the lighting module.

[0009] Furthermore, a wrench head rotating shaft is provided in the middle connection between the wrench handle connection structure and the wrench head connection module.

[0010] Furthermore, limiting modules are provided at the upper and lower ends of the upper end surface of the rotating shaft, and a handle is provided at the upper end of the limiting module.

[0011] Furthermore, a lithium battery is used inside the lighting module, and a charging hole is provided on the right side of the lighting module.

[0012] Furthermore, the lighting lamp uses an LED lamp.

[0013] Furthermore, the lower end of the wrench folding handle is connected to the rotating shaft.

[0014] The present invention has the following beneficial effects:

[0015] 1. By setting a folding handle for the wrench and a rotating shaft, the folding handle of the wrench can be retracted into the wrench handle, reducing the overall size and bringing the following benefits: Convenient for carrying: The folding handle design enables the wrench to be stored in a smaller volume when not in use, making it convenient to carry around. Operators can more easily put the wrench into a toolbox, backpack or pocket, reducing the burden of carrying tools, especially suitable for outdoor work or situations where multiple tools need to be carried. Save storage space: The folding handle design allows the wrench to occupy less space when stored, facilitating the efficient use of space in a limited storage environment. This helps to keep the toolbox or workplace tidy, making it easier to find and access other tools and improving overall work efficiency. Improve operation flexibility: The rotating shaft enables the folding handle to be adjusted at different angles according to needs, adapting to different operating environments. Even in narrow or complex working spaces, the handle position can be flexibly adjusted to ensure smooth operation, improving work efficiency and operation accuracy.

[0016] 2. By setting a lighting module, a light source can be provided in an environment with poor lighting, and the following benefits can be brought: Improve operation accuracy: The lighting module provides sufficient light, enabling operators to clearly see bolts, nuts and the working area even in an environment with poor lighting, ensuring accurate alignment for each operation and improving work quality. Improve work efficiency: In an environment with poor lighting, operators no longer need to rely on additional light sources such as flashlights or headlamps, which reduces the time for tool switching and adjustment and improves work efficiency.

[0017] 3. By setting a wrench head connection module, a wrench head connection module and a wrench head rotating shaft, the volume can be reduced by changing the angle between the handle and the wrench head, facilitating operation in a narrow environment, and the following benefits can be brought: Enhanced operation flexibility: By adjusting the angle between the handle and the wrench head, the wrench can adapt to various narrow or complex operating environments. This flexibility enables operators to perform precise operations in restricted spaces, improving work efficiency and quality. Reduce the tool volume: By changing the angle between the handle and the wrench head, the wrench can be folded or adjusted into a more compact form, making it convenient to store and carry in a narrow space. The reduced volume not only reduces the occupied space in the toolbox but also improves the portability of the tool. BRIEF DESCRIPTION OF THE DRAWINGS
