Description

Technical Field

[0001] This utility model relates to the field of hardware tools technology, and in particular to a wire cutter with adjustable torque. Background Technology

[0002] Wire cutters are tools used to cut electrical wires. They are used to cut thicker metal wires. There are generally insulated handle wire cutters and iron handle wire cutters, as well as pipe handle wire cutters. Electricians often use insulated handle wire cutters, which have a working voltage of 1000V and can be used for live-line work on low-voltage electrical equipment with wires below 380V. Wire cutters are usually used to cut wires and cables, and their specifications are expressed by their total length.

[0003] In the prior art, such as Chinese patent CN216966133U, a wire cutter is disclosed, which includes a pair of clamp bodies. The clamp body includes a clamp head and a clamp handle. The clamp head is connected to the clamp handle. The clamp head is provided with a main cutting edge, and the clamp handle is provided with a secondary cutting edge. The secondary cutting edges on the two clamp handles are opposite to each other. The main cutting edge is used to cut steel bars, and the secondary cutting edge is specifically used to cut cables. The sharpness of the secondary cutting edge is different from that of the main cutting edge. In this way, the wire cutter is functionally divided, which better meets the process requirements of cutting different materials.

[0004] However, existing wire cutters have a relatively fixed structure, and the length of the handle cannot be adjusted. Some workers have large hands, and if the handle is too short, it is inconvenient for them to cut wires. At the same time, when cutting wires, some wires are in dimly lit areas, which can easily cause the wires to be cut off at different positions, causing inconvenience to the workers. To address the above problems, a wire cutter with adjustable torque is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a torque-adjustable wire cutter.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a torque-adjustable wire cutter, comprising a clamp head assembly, with two connecting arm assemblies symmetrically mounted at both ends of the clamp head assembly. The clamp head assembly includes a first clamp head, a second clamp head, an LED lamp tube, and a control box. Two mounting rods are symmetrically fixedly mounted at both ends of the LED lamp tube, with one end of each mounting rod welded to both sides of the first clamp head. The connecting arm assembly includes a handle housing, a first fixing block, a second fixing block, an extension arm, a connecting plate, a threaded rod, a movable plate, and a limiting rod. The inner side of the handle housing is welded to the outer wall of the second fixing block. One end of the outer shell is welded to the outer wall of the first fixing block. A trapezoidal groove is formed through one side of the first fixing block. A sliding groove is formed through one side of the second fixing block. A threaded through hole is formed at one end of the first fixing block. One end of the movable plate is rotatably connected to one end of the threaded rod, and the other end of the movable plate is fixedly connected to one end of the limiting rod. The inner wall of one end of the threaded through hole is threadedly connected to the outer wall of the threaded rod, and the inner wall of the other end of the threaded through hole is slidably installed with both ends of the movable plate. The second fixing block is slidably installed with the extension arm through the sliding groove. Multiple limiting grooves are evenly formed on one side of the extension arm.

[0007] Preferably, a stop is welded to one end of the extension arm, and a spring is provided at one end of the extension arm.

[0008] Preferably, one end of the connecting plate is rotatably connected to one end of the extension arm, and the other end of the connecting plate is movably installed to one end of the spring.

[0009] Preferably, the bottom of the control box is fixedly installed to one end of the handle housing, and one end of the first pliers head is rotatably connected to one end of the second pliers head.

[0010] Preferably, the outer wall of the extension arm is slidably connected to the inner wall of the trapezoidal groove, and multiple wire breakage grooves are provided on the inner side of one end of both the first and second pliers.

[0011] Preferably, both the first and second pliers have multiple clamping tooth grooves on the inner side of one end.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by adding a control box and LED lights, when using wire cutters to cut wires in a dimly lit environment, the operator can turn on the switch on the control box to turn on the LED lights, which can illuminate the cutting areas of the first and second pliers heads. This provides auxiliary lighting in dim environments, prevents the wire from being cut off at an off-center position, and can be turned off at any time when the lighting is not needed, making it convenient to use.

[0014] 2. In this utility model, by improving the connecting arm assembly, the finger presses the connecting plate and drags it outward. After pulling the extension plate outward to the required length, the threaded rod is rotated. By rotating the threaded rod, it moves into the threaded through hole, thereby driving the limiting rod out of the threaded through hole until one end of the limiting rod is inserted into the corresponding limiting groove, thus limiting the extension plate and increasing the overall length of the handle. The overall length of the handle of the connecting arm assembly can be adjusted according to the needs of the operator, making it convenient for operators with different hand sizes to use. At the same time, the torque when using the wire cutter can be adjusted, and the adjustment process is simple and quick. Attached Figure Description

[0025] like Figures 1-3 As shown, this utility model provides a torque-adjustable wire cutter, including a clamp head assembly 1. Two connecting arm assemblies 2 are symmetrically installed at both ends of the clamp head assembly 1. The clamp head assembly 1 includes a first clamp head 11, a second clamp head 12, an LED tube 13, and a control box 17. Two mounting rods 14 are symmetrically fixedly installed at both ends of the LED tube 13. One end of the mounting rod 14 is welded to both sides of the first clamp head 11. The bottom of the control box 17 is fixedly installed to one end of the handle housing 21. One end of the first clamp head 11 is rotatably connected to one end of the second clamp head 12. Multiple wire cutting grooves 15 are opened on the inner side of one end of the first clamp head 11 and the second clamp head 12. Multiple clamping grooves 16 are opened on the inner side of one end of the first clamp head 11 and the second clamp head 12.

[0026] In this embodiment, when using wire cutters to cut wires, in dim environments, workers can turn on the switch on the control box 17 to turn on the LED light tube 13, which can illuminate the cutting area of ​​the first pliers head 11 and the second pliers head 12, thus providing auxiliary lighting in dim environments and preventing the wire from being cut at an off-center position.

[0027] Example 2

[0028] like Figures 3-6As shown, this utility model provides a torque-adjustable wire cutter. The connecting arm assembly 2 includes a handle housing 21, a first fixing block 22, a second fixing block 23, an extension arm 24, a connecting plate 28, a threaded rod 210, a movable plate 211, and a limiting rod 212. The inner side of the handle housing 21 is welded to the outer wall of the second fixing block 23, and the inner side of one end of the handle housing 21 is welded to the outer wall of the first fixing block 22. A trapezoidal groove 213 is formed through one side of the first fixing block 22, and a sliding groove 27 is formed through one side of the second fixing block 23. A threaded through hole 214 is formed at one end of the first fixing block 22. One end of the movable plate 211 is rotatably connected to one end of the threaded rod 210, and the movable plate 211... The other end is fixedly connected to one end of the limiting rod 212. The inner wall of one end of the threaded through hole 214 is threadedly connected to the outer wall of the threaded rod 210, and the inner wall of the other end of the threaded through hole 214 is slidably installed with both ends of the movable plate 211. The second fixed block 23 is slidably installed with the extension arm 24 through the sliding groove 27. Multiple limiting grooves 25 are evenly opened on one side of the extension arm 24. A stop block 26 is welded to one end of the extension arm 24, and a spring 29 is provided at one end of the extension arm 24. One end of the connecting plate 28 is rotatably connected to one end of the extension arm 24, and the other end of the connecting plate 28 is movably installed with one end of the spring 29. The outer wall of the extension arm 24 is slidably connected to the inner wall of the trapezoidal groove 213.

[0029] In this embodiment, when it is necessary to adjust the overall length of the handle of the wire cutter, simply insert your finger into the trapezoidal groove 213, press the connecting plate 28 with your finger while dragging it outward. After the connecting plate 28 is completely removed from the trapezoidal groove 213, the connecting plate 28 returns to the open state under the elastic force of the spring 29. After pulling the extension plate 24 outward to the required length, rotate the threaded rod 210 to move the threaded rod 210 into the threaded through hole 214, thereby driving the limiting rod 212 out of the threaded through hole 214 until one end of the limiting rod 212 is inserted into the corresponding limiting groove 25, thereby limiting the extension plate 24. This achieves the purpose of increasing the overall length of the handle according to the needs of the operator, and adjusting the overall length of the handle of the connecting arm assembly 2, making it convenient for operators with different hand sizes to use.

[0030] The device is used and works as follows: The wire cutter consists of a plier head assembly 1 and a connecting arm assembly 2. When using the wire cutter to cut wires, in a dimly lit environment, the operator can turn on the switch on the control box 17 to turn on the LED light tube 13, which can illuminate the cutting area of ​​the plier head 11 and the plier head 2 12. This provides auxiliary lighting in dim environments and prevents the wire from being cut off at an incorrect position. The lighting can be turned off at any time when it is not needed, making it convenient to use.

[0031] By improving the connecting arm assembly 2, such as... Figure 1The diagram shows the normal operating state of the wire cutter. When the operator has a large hand and needs to adjust the overall length of the handle, simply insert your finger into the trapezoidal groove 213 (the connecting plate 28 is in an open state inside the trapezoidal groove 213), press the connecting plate 28 with your finger while pulling it outward (the spring 29 is compressed under the pressure). After the connecting plate 28 is completely removed from the trapezoidal groove 213, the connecting plate 28 returns to the open state under the elastic force of the spring 29. After pulling the extension plate 24 outward to the required length, rotate the threaded rod 210. The outer wall is threaded to the inner wall of the threaded through hole 214. By rotating the threaded rod 210, the threaded rod 210 moves into the threaded through hole 214, thereby driving the limiting rod 212 out of the threaded through hole 214 until one end of the limiting rod 212 is inserted into the corresponding limiting groove 25, thereby limiting the extension plate 24. This achieves the purpose of increasing the overall length of the handle according to the needs of the operator, and adjusting the overall length of the handle of the connecting arm assembly 2, making it convenient for operators with different hand sizes to use. At the same time, the torque when using the wire cutter can be adjusted, and the adjustment process is simple and quick.

[0032] When the extension plate 24 needs to be put back, simply rotate the threaded rod 210 to return the limiting rod 212 to the threaded through hole 214, press the connecting plate 28 with your finger and move the extension plate 24 into the trapezoidal groove 27 until the connecting plate 28 is completely moved into the trapezoidal groove 27. This makes it easy to store the extension plate 24, reduces the space occupied by the wire cutter when not in use, and makes it easy to carry.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
