Description

[0001] This application is a divisional application. The original application has the application number 2024219751711 and the original application date is 20240815. The invention title of the original application is a multi-functional pliers. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of work tools, and more specifically, to a multifunctional pair of pliers. Background Technology

[0003] Pliers, a widely used hand tool in daily life and industrial production, possess a variety of functions due to the diversity of their head shapes. When performing various repair, assembly, or disassembly operations, people often need to prepare and use different types of pliers depending on the specific needs. For example, needle-nose pliers are suitable for delicate tasks, while broadhead pliers are suitable for tightening wires. Therefore, in normal work processes, people often need to carry multiple types of pliers for unforeseen circumstances to handle various tasks. However, when using pliers, in addition to the pliers themselves, other auxiliary tools are needed to ensure the smooth progress of the work. For example, screwdrivers are used to tighten or loosen screws, voltage testers are used to check if a circuit is live, and utility knives can be used to cut or trim materials. These auxiliary tools play an indispensable role in the work, allowing the pliers to achieve their maximum effectiveness. In the present technology, to facilitate the carrying of these tools, people usually use a tool belt that wraps around the waist. This belt can be equipped with multiple pockets and loops for storing and securing various tools, allowing workers to easily carry the necessary tools with them. However, while this carrying method improves tool portability to some extent, its carrying space remains limited, unable to accommodate too many tools. Furthermore, carrying a large number of tools increases the weight of the belt, burdening the worker and potentially affecting their flexibility and comfort. Therefore, how to improve tools to save carrying space has become an urgent problem to be solved. Summary of the Invention

[0004] To address the issue of excessive space consumption when carrying a large number of tools in existing technologies, this solution provides a multi-functional pair of pliers. This solution utilizes storage spaces within the first pair of pliers and the second handle to carry and store auxiliary tools, thereby reducing the space occupied by these tools.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A multi-functional pair of pliers, including First clamp handle; The second clamp handle is hinged to the front end of the first clamp handle. The pliers head is connected to the first pliers handle (100) and the second pliers handle (200); An accommodating space is provided on the first and / or second clamp handles, and an auxiliary tool is detachably connected inside it.

[0006] The pliers head is detachably connected to the hinge of the first and second handles, allowing the head and handles to be separated and replaced individually. During operation, only one multi-purpose pliers and several heads are needed to perform different types of plier work, thus reducing carrying weight. Furthermore, a storage space is provided on either the first or second handle to store frequently used auxiliary tools. These tools can be directly retrieved from this storage space, freeing up space to carry other tools.

[0007] In the multi-functional pliers of this application, the first pliers handle further includes a front part and a rear part connected at their ends. The front part is provided with the accommodating space along its axial direction. The rear part is fixedly connected to the auxiliary tool at its end. The auxiliary tool is adapted to the shape and size of the accommodating space.

[0008] In the multi-functional pliers of this application, the cover plate further includes a first sealing plate and a second sealing plate connected end-to-end with the first sealing plate, with a buckle fixed under the first sealing plate; reinforcing ribs are fixed to the first and second sealing plates. The cover plate including the first sealing plate and the second sealing plate connected end-to-end allows the first and second sealing plates to form an L-shape, which improves the strength of the cover plate and prevents it from being too soft. Furthermore, the reinforcing ribs can also improve the connection strength of the cover plate to a certain extent, preventing the first and second sealing plates from being too soft.

[0009] In the multi-functional pliers of this application, the auxiliary tool further includes a voltage tester. The conductive post of the voltage tester is inserted into the accommodating space and contacts a conductive block within the accommodating space. The conductive block is electrically connected to the pliers head. The first pliers handle has a window communicating with the accommodating space. Similarly, without removing the voltage tester from the pliers, the pliers can operate while simultaneously checking for electric shock at the pliers head, without needing to switch back and forth. Current flows sequentially through the pliers head and the conductive block into the conductive post of the voltage tester, and the indicator on the voltage tester handle can be directly observed through the window to see if it is energized.

[0010] In the multi-functional pliers of this application, both the first and second pliers handles are provided with channels that connect to the receiving area of ​​the pliers head. An elastic element and a ball bearing are sequentially fixed within the channels, with the elastic element elastically pressing against the ball bearing. When the pliers head engages within the receiving area, the ball bearing retracts into the channel under the pressure of the pliers head. After the pliers head is fully engaged, the ball bearing is pressed into the recess of the pliers head arm by the elastic element, thus securing the pliers head.

[0011] In the multi-functional pliers of this application, a spring is further connected between the first and second pliers. The spring provides a rebound force when the first and second pliers separate.

[0012] Compared with the prior art, the technical solution provided by this utility model has the following advantages: The multi-functional pliers provided by this utility model have detachable plier heads connected to the hinge joint of the first and second plier handles, allowing the plier heads and handles to be separated and replaced individually. During operation, only one multi-functional pliers and several plier heads are needed to perform different types of plier operations, thereby reducing the carrying weight. Furthermore, by providing a storage space on the first and / or second plier handles, auxiliary tools are detachably connected inside. When in use, these tools can be directly removed from the storage space of the pliers, saving space that can be used to carry more other tools. Attached Figure Description

[0018] Example 1 like Figure 1 As shown, this application provides a multi-functional pliers, including a first plier handle 100 and a second plier handle 200. The second plier handle 200 is hinged to the front part 110 of the first plier handle 100. The first plier handle 100 and the second plier handle 200 rotate about their hinge point. A plier head 300 is detachably connected to the hinge point of the first plier handle 100 and the second plier handle 200. The two arms of the plier head 300 are respectively engaged in the first plier handle 100 and the second plier handle 200. When the first plier handle 100 and the second plier handle 200 rotate along their hinge point, the two arms of the plier head 300 open or close, realizing the pliers clamping function. A receiving space 400 is provided on the first plier handle 100 and / or the second plier handle 200, and an auxiliary tool 500 is detachably connected inside it.

[0019] The multi-functional pliers feature detachable plier heads 300 connected to the hinge joint between the first plier handle 100 and the second plier handle 200, allowing the heads and handles to be separated and replaced individually. During operation, only one multi-functional pliers and several plier heads 300 are needed to perform different types of plier head operations, thus reducing carrying weight. Furthermore, by providing a storage space 400 on the first plier handle 100 and / or the second plier handle 200, an auxiliary tool 500 is detachably connected inside. When in use, the tool can be directly removed from the storage space 400, saving space that can be used to carry more other tools.

[0020] like Figure 4 As shown, both the first clamp handle 100 and the second clamp handle 200 are provided with channels 140, which connect to the receiving area 170 of the clamp head 300. An elastic element 150 and a ball bearing 160 are sequentially fixed within the channel 140. The elastic element 150 elastically presses against the ball bearing 160. The elastic element 150 can be a spring or rubber. When the clamp head 300 is engaged in the clamp head receiving area 170, the ball bearing 160 retracts into the channel 140 under the pressure of the clamp head 300. After the clamp head 300 is fully engaged, the ball bearing 160 is pressed into the recess of the clamp head arm by the elastic element 150, thus fixing the clamp head 300.

[0021] A spring 210 is connected between the first clamp 100 and the second clamp 200, and the spring 210 provides a rebound force for the separation of the first clamp 100 and the second clamp 200.

[0022] Example 2 like Figure 2-5As shown, the first pliers handle 100 includes a front portion 110 and a rear portion 120 connected at both ends. The front portion 110 has an accommodating space 400 along its axial direction. An auxiliary tool 500 is fixedly connected to the end of the rear portion 120. The auxiliary tool 500 is adapted to the shape and size of the accommodating space 400. The auxiliary tool 500 includes, but is not limited to, a voltage tester 510, a screwdriver, and a blade, or one or more of these. In this embodiment, the auxiliary tool 500 includes a voltage tester 510, and the handle 511 of the voltage tester 510 is integrally formed with the rear portion 120. The conductive post 512 of the voltage tester 510 is inserted into the accommodating space 400 and contacts the conductive block 410 within the accommodating space 400. The conductive block 410 is electrically connected to the pliers head 300. The conductive block 410 includes a flashlight 411, a connecting plate 412, and a spring clip 413. The connecting plate 412 is fixedly connected to the end of the flashlight 411. One end of the spring piece 413 is fixedly and inclined to the bottom of the connecting plate 412. After the pliers head 300 is inserted into the pliers handle, the spring piece 413 is elastically connected to the pliers handle. When the conductive post 512 of the voltage tester 510 is inserted into the flashlight 411, it applies a pushing force to the flashlight 411, causing the spring piece 413 to deform, ensuring that the spring piece 413 is tightly connected to the pliers head 300 and does not loosen. During the use of the pliers, the current will pass through the pliers head 300 and the conductive block 410 in sequence into the conductive post 512 of the voltage tester 510, and the current will be displayed on the handle 511 of the voltage tester 510 to indicate whether there is electricity. Therefore, the voltage tester 510 can be used without detaching from the pliers, allowing the pliers to work while simultaneously checking whether the pliers head 300 is exposed to electricity, without having to switch back and forth, which is convenient for the operator and improves work efficiency.

[0023] like Figure 2-5 As shown, to enhance the structural strength of the second clamp handle 200 and reduce the risk of breakage, the rear connector 120 is engaged within the L-shaped groove 111 on the outer side of the front connector 110, forming the same shape as the second clamp handle 200. The L-shaped groove 111 on the front connector 110 allows it to extend through the entire length of the second clamp handle 200, increasing its strength and preventing breakage during force application.

[0024] Example 3 like Figure 2-5As shown, based on Embodiment 2, to further prevent the rear connector 120 from detaching from the front connector 110, a magnetic attraction structure 130 is provided at the contact surface between the front connector 110 and the rear connector 120, so that the front connector 110 and the rear connector 120 are magnetically connected. The magnetic attraction mechanism includes a magnet connected to the front connector 110 and an iron block connected to the rear connector 120. The magnet and the iron block are magnetically attached when they are close together. The magnetic attraction structure 130 can ensure that the front connector 110 can be tightly attracted to the rear connector 120 when they are connected, and the connection remains firm and does not detach even when there is no force between them.

[0025] Example 4 like Figure 2-5 As shown, to prevent the pliers from shifting under force, a protrusion 121 and a groove that matches the protrusion 121 are respectively provided at the contact surfaces of the front part 110 and the rear part 120. The protrusion 121 and the groove engage 112 to limit the shift of the rear part 120. The presence of a protrusion 121 and a groove that matches the protrusion 121 at the contact surfaces of the front part 110 and the rear part 120 can limit the shift of the handle 511 along the direction perpendicular to the force direction, making it easier for the pliers to grip the handle 511 firmly when force is applied.

[0026] Example 5 like Figure 6 As shown, the auxiliary tool 500 is completely built into the receiving space 400, and the entrance of the receiving space 400 is engaged with the cover plate 600. The fact that the auxiliary tool 500 is completely built into the receiving space 400 prevents it from being exposed, reducing the risk of it detaching from the pliers. The cover plate 600 can open and close the receiving space 400 for easy access. The cover plate 600 includes a first sealing plate 610 and a second sealing plate 620 connected end-to-end with the first sealing plate 610. A buckle 630 is fixed under the first sealing plate 610; reinforcing ribs 640 are fixed on the first sealing plate 610 and the second sealing plate 620. The cover plate 600, including the first sealing plate 610 and the second sealing plate 620 connected end-to-end, allows the first sealing plate 610 and the second sealing plate 620 to form an L-shape, increasing the strength of the cover plate 600 and preventing it from being too soft. In addition, the reinforcing rib 640 can also improve the connection strength of the cover plate 600 to a certain extent, preventing the first sealing plate 610 and the second sealing plate 620 from being too soft.

[0027] Example 6 like Figure 7As shown, based on Embodiment 6, the auxiliary tool 500 further includes a voltage tester 510. The conductive post 512 of the voltage tester 510 is inserted into the accommodating space 400 and contacts the conductive block 410 within the accommodating space 400. The conductive block 410 is electrically connected to the pliers head 300. The first pliers handle 100 has a window 650 communicating with the accommodating space 400. Similarly, without removing the voltage tester 510 from the pliers, the pliers can be used while simultaneously checking whether the pliers head 300 is exposed to electricity, without needing to switch back and forth. The current will sequentially pass through the pliers head 300 and the conductive block 410 into the conductive post 512 of the voltage tester 510, and the status of the voltage tester 510 can be directly observed through the window 650 on the handle 511 of the voltage tester 510.
