Abstract
Description
A detachable tongs Technical Field
[0001] This utility model relates to the field of electrical disassembly tools, and in particular to a detachable pliers. Background Technology
[0002] In the engineering equipment and automotive industries, a large number of connectors are used to ensure the reliability of electrical wiring connections. To ensure the reliability and protective performance of connectors, they are often complex to manufacture and precisely fitted. While this ensures connection reliability and stability, it also brings inconvenience in maintenance, especially during the disassembly of connectors or replacement of terminals, where the internal locking plates are very difficult to remove. As shown in Figure 1, connector 1 contains wiring pins 4. To ensure the pins are fixed and reliable, locking plates 3 are secured to connector 1 using various clips, ensuring that pins 4 will not loosen or have poor contact during use. When disassembling using a conventional tool 2, the operation is mainly by pulling, which is not only laborious but also makes the operation process and force uncontrollable, easily damaging the connector components and prone to accidents during the pulling process. The conventional disassembly process is shown in Figure 2.
[0003] Due to the small size of the connector itself, to ensure reliable electrical connections, the internal components such as pins and locking tabs require high dimensional precision and are tightly installed. During maintenance and replacement, when using a conventional tool for disassembly, the entire process relies on the tool's lifting end to hook the locking tab and pull directly. This connection method is inherently unreliable. Secondly, the pulling force is entirely controlled manually. After the internal structure of the connector deforms, the locking tab may slip out. During this process, manual pulling cannot accurately control the pulling force and stroke, easily leading to slippage. Before the locking tab slips out, the pulling stroke is almost zero; once it slips out, the uncontrollable human intervention can cause excessive pulling stroke, easily damaging the locking tab or connector materials, and posing a risk of tool injury during the pulling process. Furthermore, conventional tools are custom-designed; a different tool must be used for each type of connector or locking tab structure, making it inconvenient for complex working conditions and multi-connector type operations. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] Based on this, the present invention provides a detachable pliers to solve the problems of uncontrollable stroke and force, easy damage to connectors, operational risks, and inability to meet the needs of multiple working conditions during connector disassembly.

Detailed Implementation
[0036] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0037] Example 1:
[0038] As shown in Figure 3, a detachable pliers according to this embodiment includes a pliers body, a protective sleeve 6, a return spring 7, a fixed pliers head, a movable pliers head 9, a locking pin 10, a pliers, a locking device 12, and a pin 13. The pliers body comprises two pliers connected at their midpoints, namely a first pliers body and a second pliers body, which are connected by the pin 13. The first and second pliers bodies can rotate circumferentially around the pin, thereby achieving directional movement between the working end and the handle end of the pliers body. The end of the first and second pliers body located in front of the pin 13 is the working end, and the end located behind the pin 13 is the handle end. The pin 13 is closer to the working end of the pliers body (i.e., the distance from the pin to the end of the working end of the pliers body is less than the distance from the pin to the end of the handle end of the pliers body), making operation less strenuous and improving operational accuracy. In this embodiment, the clamp body is a same-side clamp body 5, the working end of the first clamp body and the handle end of the first clamp body are located on the same side of the pin 13, and the working end of the second clamp body and the handle end of the second clamp body are located on the other side of the pin 13.
[0039] The handles of the first and second clamps are respectively fitted with protective sleeves 6. The protective sleeves 6 can provide basic protection during operation, including but not limited to anti-slip, insulation, and anti-detachment.
[0040] A return spring 7 is provided between the handle ends of the first clamp and the second clamp. When the operator releases the closed handle ends of the first clamp and the second clamp, the first clamp and the second clamp can automatically return to their original positions by relying on the tension of the return spring 7.
[0041] The fixing jaw is installed at the working end of the first jaw body and is hollow, so that the fixing jaw can directly contact the working part (connector) without affecting the operation of the object picker. In this embodiment, the fixing jaw is an O-type fixing jaw 8, and the O-type fixing jaw 8 is a hollow O-type.
[0042] The movable pliers head 9 is fixed to the working end of the second pliers body by a locking pin 10. The object picker includes an end head and a picking end. The end head of the object picker is fixed to the movable pliers head 9 by a locking device 12, and the picking end of the object picker passes through the hollow part of the fixed pliers head 8.
[0043] In this embodiment, the object retriever is a first-type object retriever 11. The first-type object retriever 11 retrieves objects by pulling, that is, the pulling direction is the same as the object retrieval direction. As shown in Figure 4, when the handle ends of the first and second clamps are separated, the fixed clamp head and the movable clamp head 9 move closer together; when the handle ends of the first and second clamps are closed, the fixed clamp head and the movable clamp head 9 move away from each other; thereby driving the first-type object retriever 11 to pull and retrieve objects, changing the pulling direction to a downward pressing action of the handle end of the clamp body.
[0044] Example 2:
[0045] As shown in Figure 5, compared with Embodiment 1, the difference in this embodiment is that: the pliers body is an eccentric pliers body 14, the working end of the first pliers body and the handle end of the second pliers body are located on the same side of the pin 13, and the working end of the second pliers body and the handle end of the first pliers body are located on the other side of the pin 13; the fixed pliers head is a U-shaped fixed pliers head 15, which is a hollow U-shape; the object picker is a second type of object picker 16, which picks up objects by pressing, that is, the pressing direction is opposite to the object picking direction.
[0046] As shown in Figure 6, when the handles of the first and second clamps are separated, the fixed clamp head and the movable clamp head 9 move away from each other; when the handles of the first and second clamps are closed, the fixed clamp head and the movable clamp head 9 move closer together; thereby driving the second type of object picker 16 to press and pick up the object, which is equivalent to using the object picker end of the second type of object picker 16 to push out the parts in the connector, changing the pressing direction to the downward pressing action of the handle end of the clamp body.
[0047] Apart from the above, the other parts of Example 2 are the same as those of Example 1.
[0048] This utility model's tongs employs a lever structure, which reduces operating effort at the handle end of the tongs body while improving the operational precision of the working end, preventing product damage and material spillage during tong retrieval. Furthermore, the locking device 12 allows for quick and easy disassembly of the tongs 11, enabling the replacement of different types of tongs and making it suitable for various working conditions.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and not to limit it; although the implementation of this utility model has been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this utility model, and such modifications and variations all fall within the scope defined by the appended claims.
