Description

Technical Field

[0001] This utility model relates to wrenches, and more particularly to homemade wrenches. Background Technology

[0002] An electrical module box is a box used to manage and store electronic components. It has multiple small compartments, each capable of holding a small part or electronic component. These boxes offer advantages such as modular management, portability, and categorized storage, and are widely used in electronics, toys, hardware, plastics, machinery, and household goods industries.

[0003] The sensor cables on the electrical module box are too long, making them inconvenient to use (see attached document). Figure 1 Instead of a ring-shaped wrench, an open-end wrench is used to install the sensor cable.

[0004] Because there are many sensor cables that need to be installed and connected on the electrical module box, when wiring, there are always a few gland (grounding terminal) that cannot be fitted with an open-end wrench due to narrow space, which makes it impossible to secure the cable. Even if an open-end wrench can be fitted, the gland can only be tightened little by little, which takes a long time. Since a lot of cables need to be installed on the electrical module box, this affects the installation progress. Utility Model Content

[0005] This utility model provides a self-made wrench, which solves the technical problems of box wrenches being unable to be installed, taking too long to install, and affecting the installation progress. The following technical solution is provided:

[0006] A homemade wrench, comprising a wrench body, characterized in that, when the wrench body is an open-end wrench, two first notches are provided on the head of the open-end wrench, the two first notches being respectively provided on both sides of the width direction of the open end of the head of the open-end wrench;

[0007] When the wrench body is a box wrench, a second notch is provided on the head of the box wrench, so that the head of the box wrench is open.

[0008] By adopting the above technical solution, the head of the open-end wrench is made smaller by setting the first notch. This reduces the space occupied by the head of the open-end wrench when installing the sensor cable, making it easier to insert the open-end wrench and leaving more space to rotate the open-end wrench. This reduces the time spent fixing the cable and speeds up the installation process.

[0009] By setting the second notch, the head of the box wrench is made to resemble the head of the open-end wrench. Therefore, the box wrench can be installed by passing the sensor cable through the second notch. The structure is simple, and an additional tool for installing cables is added, thereby speeding up the installation efficiency.

[0010] Furthermore, the open-end wrench includes a first handle and a first head that is open in shape, the first head being fixedly mounted on one end of the first handle; the first notch is provided along the length direction of the first handle.

[0011] Furthermore, the wrench body is a box wrench, which includes a second handle and a second head. The second head is fixedly mounted on one end of the second handle, and the second notch is provided on the side wall of the second head away from the second handle.

[0012] Furthermore, the second handle has two third notches at one end near the second head, and the two third notches are respectively located on the two end faces corresponding to the thickness direction of the second handle; the two third notches have the same structure, and the thickness of the two second notches gradually decreases from near the second head to away from the second head.

[0013] By adopting the above technical solution and setting the third notch, the gland on the cable can be tightened without using a lot of force. Therefore, the second handle of the box wrench does not need to have high strength. Thus, the setting of the third notch will not affect the installation of the cable with the box wrench, but will allow for a larger angle to turn the box wrench, thereby saving the time required for installation and speeding up the installation process.

[0014] Furthermore, the first head includes an integrally formed support section, a first jaw and a second jaw. The support section is fixedly disposed at one end of the first handle. The first jaw and the second jaw are both disposed along the length direction of the first handle. The two first notches are respectively disposed at opposite ends of the first jaw and the second jaw.

[0015] Furthermore, the width of the second notch is greater than the diameter of the cable.

[0016] By adopting the above technical solution and setting the second notch, the sensor cable can smoothly enter the open end of the box wrench through the second notch, thereby enabling the box wrench to have the function of an open-end wrench, providing an installation tool for installing cables, thereby speeding up the installation efficiency.

[0017] In summary, this application has the following beneficial effects:

[0018] 1. By setting the first notch, the head of the open-end wrench is made smaller. This reduces the space occupied by the head of the open-end wrench when installing sensor cables, making it easier to insert the open-end wrench and leaving more space to turn the open-end wrench. This reduces the time spent fixing the cable and speeds up the installation process.

[0019] By setting the second notch, the head of the box wrench is made to resemble the head of the open-end wrench. Therefore, the box wrench can pass through the second notch to install the sensor cable. The structure is simple, and an additional tool for installing cables is added, thereby speeding up the installation efficiency.

[0020] 2. With the third notch, the gland on the cable can be tightened without much force. Therefore, the second handle of the box wrench does not need to be very strong. The third notch will not affect the installation of the cable with the box wrench, but will allow for a larger angle to turn the box wrench, thereby saving the time required for installation and speeding up the installation process.

[0021] 3. With the second notch, the sensor cable can smoothly enter the open end of the box wrench through the second notch, thus enabling the box wrench to function as an open-end wrench, providing an installation tool for installing cables and thereby speeding up the installation process.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] In a specific embodiment, reference is made to... Figure 1-6 A homemade wrench includes a wrench body. When the wrench body is an open-end wrench 1, the open-end wrench 1 has two first notches 2 on its head. The two first notches 2 are respectively located on both sides of the width direction of the open end of the head of the open-end wrench 1. In this specific embodiment, the open-end wrench 1 is an open-end wrench 1 suitable for screws or nuts with diameters of 15mm, 18mm and 30mm.

[0032] When the wrench body is a box wrench 3, a second notch 4 is provided on the head of the box wrench 3, so that the head of the box wrench 3 is open; in this specific embodiment, the box wrench 3 is a box wrench 3 suitable for screws or nuts with a diameter of 24mm.

[0033] The first notch 2 makes the head of the open-end wrench 1 smaller. This reduces the space occupied by the head of the open-end wrench 1 when installing the sensor cable, making it easier to insert the open-end wrench 1 and leaving more space to rotate the open-end wrench 1, thereby reducing the time spent fixing the cable and speeding up the installation efficiency.

[0034] The second notch 4 makes the head of the box wrench 3 resemble the head of the open-end wrench 1, thus allowing the box wrench 3 to pass through the sensor cable and be installed. The structure is simple, thereby adding an installation tool for the cable and speeding up the installation efficiency.

[0035] like Figure 3 As shown, the open-end wrench 1 includes a first handle 11 and a first head 12 that is open. The first head 12 is fixedly mounted on one end of the first handle 11. The first notch 2 is provided along the length of the first handle 11.

[0036] like Figure 4 As shown, the wrench body is a box wrench 3. The box wrench 3 includes a second handle 31 and a second head 32. The second head 32 is fixedly installed at one end of the second handle 31. The second notch 4 is provided on the side wall of the second head 32 away from the second handle 31.

[0037] In this specific embodiment, the sidewalls of the second head 32 corresponding to the second notch 4 are all inclined. The width of the second notch 4 gradually increases from the inner circle to the outer circle of the second head 32. At this time, the second notch 4 can provide a guiding function for inserting the box wrench 3 into the cable, so that the box wrench 3 can pass through the sensor cable more quickly.

[0038] like Figure 4 and Figure 5As shown, two third notches 5 are provided at one end of the second handle 31 near the second head 32. The two third notches 5 are respectively provided on the two end faces of the second handle 31 corresponding to the thickness direction. The two third notches 5 have the same structure. The thickness of the two second notches 4 is gradually reduced from near the second head 32 to away from the second head 32.

[0039] When tightening the cable, it is not necessary to use a lot of force to tighten it, so the second handle 31 of the wrench 3 does not need to have high strength. Therefore, the setting of the third notch 5 will not affect the installation of the cable by the wrench 3, but allows for a larger angle to rotate the wrench 3, thereby saving the time required for installation and speeding up the installation process.

[0040] like Figure 3 and Figure 6 As shown, the first head 12 includes an integrally formed support section 1201, a first jaw 1202 and a second jaw 1203. The support section 1201 is fixedly disposed at one end of the first handle 11. The first jaw 1202 and the second jaw 1203 are both disposed along the length direction of the first handle 11. Two first notches 2 are respectively disposed at opposite ends of the first jaw 1202 and the second jaw 1203.

[0041] The second notch 4 allows the sensor cable to smoothly enter the open end of the box wrench 3 through the second notch 4, thereby enabling the box wrench 3 to have the capability of an open wrench 1, thus providing a new way to install cables and speeding up the installation process.

[0042] The width of the second notch 4 is greater than the diameter of the cable. In this specific embodiment, the width of the second notch 4 is slightly greater than the diameter of the thickest cable in the sensor cable, so that the box wrench 3 in this application can tighten the Gland on all the cables. Because the width of the second notch 4 is slightly greater than the diameter of the thickest cable in the sensor cable, this can save the production time of processing the box wrench 3 and save production costs.

[0043] Working principle: When the open-end wrench 1 is used as the wrench body, a first notch 2 is provided at one end of the first jaw 1202 and the second jaw 1203 that are far apart from each other. At this time, the volume of the open-end wrench 1 is reduced, making it easier to put the open-end wrench 1 into the cable and twist the cable.

[0044] When using the box wrench 3 as the wrench body, a second notch 4 is provided at the end of the second head 32 away from the second handle 31. After the second notch 4 is provided, the box wrench 3 can be inserted into the cable through the second notch 4. After the third notch 5 is provided on the second handle 31, the rotation angle of the box wrench 3 can be expanded. At this time, the box wrench 3 can be used to tighten the cable.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] The present invention has been described above with reference to specific embodiments. However, those skilled in the art should understand that these descriptions are exemplary and not intended to limit the scope of protection of the present invention. Those skilled in the art can make various modifications and variations to the present invention based on its spirit and principles, and these modifications and variations are also within the scope of the present invention.
