Technical Field
[0001] This utility model relates to the field of wire strippers, and more particularly to a handheld wire stripper. Background Technology
[0002] Wire strippers are a common tool used by electricians to precisely strip the insulation from the ends of wires without damaging the internal metal conductors. During operation, select the appropriate notch, clamp, and then rotate or pull to cleanly remove the outer sheath, ensuring a secure and safe connection. This greatly improves work efficiency and is an essential tool for electrical installation and maintenance. Handheld wire strippers are lightweight and portable manual tools designed specifically for precisely stripping the insulation from wires. They are suitable for on-site electrical installation, equipment repair, and electronic fabrication, significantly improving work efficiency and wiring quality, making them a powerful assistant in electrical work.
[0003] Traditional wire strippers have relatively weak holding ability during the wire stripping process, relying heavily on manual holding by the worker. This can easily cause fatigue for the worker and reduce work efficiency. Traditional wire strippers are also relatively simple tools, which limits the worker's ability to work and requires them to find other auxiliary tools, resulting in unnecessary time waste.
[0004] Therefore, those skilled in the art have provided a handheld wire stripper to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a handheld wire stripper. Different sized cutting rings allow for the clamping of wires of varying sizes, making the work more convenient and efficient for workers, thus avoiding unnecessary time waste. The first blade enables faster and more efficient cutting of the wire, while the clamping teeth hold the wire to be stripped. The second blade and cross-shaped cutting head provide workers with a wider range of tools, further enhancing their efficiency and reducing unnecessary time waste.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A handheld wire stripper includes a multi-functional mechanism. The multi-functional mechanism includes a first fixed block, a third blade fixedly connected to the front outer wall of the first fixed block, a first rotating block fixedly connected to one side outer wall of the first fixed block, a first rotating column rotatably connected to the middle of the upper surface of the first rotating block, a second rotating block rotatably connected to the lower end of the outer wall of the first rotating column, a second fixed block fixedly connected to the outer wall of the second rotating block near the first rotating column, a first blade fixedly connected to the rear outer wall of the second fixed block, a clamping tooth provided on one side of the front outer wall of the second fixed block, and a cutting ring provided on the side of the front outer wall of the second fixed block away from the clamping tooth. A fixing mechanism is provided on the outer wall of the second rotating block away from the second fixed block. The fixing mechanism includes a first handle fixedly connected to the outer wall of the second rotating block away from the second fixed block. A pressing groove is opened inside the first handle. A shell is fixedly connected inside the pressing groove. A third fixed block is fixedly connected to the front end of the inner wall of the shell. A sliding column is slidably connected inside the third fixed block. A limit block is fixedly connected to the outer wall of the sliding column near the third fixed block. A spring is fixedly connected to the outer wall of the rear end of the limit block. A fourth fixed block is fixedly connected to the end of the spring away from the limit block. A sliding block is fixedly connected to the outer wall of the sliding column near the fourth fixed block. Steel balls are arranged around the outer wall of the sliding block. A second handle is fixedly connected to the outer wall of the first rotating block away from the first fixed block. A snap-fit groove is opened inside the second handle. The above technical solution allows for the clamping of wires of different sizes using cutting rings of varying sizes, making the work more convenient for workers, improving their efficiency, and avoiding unnecessary time waste. The first blade enables faster and more efficient cutting of wires, while the clamping teeth clamp the wires to be stripped. The second blade and cross-shaped cutting head provide workers with a wider variety of tools, further improving their efficiency and reducing unnecessary time waste.
[0007] Furthermore, a groove is provided inside the first handle, and a second rotating column is rotatably connected inside the groove. A first connecting rod is fixedly connected to the outer wall of the second rotating column, and a second blade is fixedly connected to the outer wall of the first connecting rod on the side away from the second rotating column. With the above technical solution, when the wire is clamped by the shearing ring, pressing the sliding column will cause the sliding column to drive the limiting block to press the spring downward, causing the sliding block to move outward while the steel ball will retract inward and disengage from the locking groove. When the wire is clamped to the appropriate size by the shearing ring, the sliding column can be released to drive the steel ball to lock into the locking groove. This mechanism can reduce the workload of the workers, allowing them to stop holding the handle tightly all the time, making their work more convenient and improving their work efficiency.
[0008] Furthermore, the second handle has a groove inside, a third rotating column is rotatably connected inside the groove, a second connecting rod is fixedly connected to the outer wall of the third rotating column, and a cross blade is fixedly connected to the outer wall of the second connecting rod on the side away from the third rotating column. The above technical solution allows the second connecting rod and the cross cutter head to be placed inside the groove, and allows the second connecting rod and the cross cutter head to rotate via the third rotating column.
[0009] Furthermore, the upper surface of the second rotating block is rotatably connected to the lower surface of the first rotating block, a baffle is slidably connected inside the groove, a clamping tooth is provided on one side of the outer wall of the rear end of the first fixed block, and a shearing ring is provided on the side of the outer wall of the rear end of the first fixed block away from the clamping tooth. The above technical solution uses a baffle that slides inside the groove to prevent worker injury, improve comfort, and limit the movement of tools inside.
[0010] Furthermore, the limiting block slides on the inner wall of the outer shell; The above technical solution allows the limiting block to slide on the inner wall of the outer shell.
[0011] Furthermore, the sliding block slides on the inner wall of the outer casing; The above technical solution enables the sliding block to slide on the inner wall of the outer casing.
[0012] Furthermore, the fourth fixing block is fixedly connected to the outer shell, and the sliding column is slidably connected to the fourth fixing block; The above technical solution can be used to fix the fourth fixing block to the outer shell.
[0013] Furthermore, the steel ball engages with the locking groove; The above technical solution enables the steel ball to engage with the locking groove.
[0014] This utility model has the following beneficial effects: 1. This utility model proposes a handheld wire stripper. Different sized cutting rings can clamp wires of different sizes, making the work more convenient for workers, improving their work efficiency and avoiding unnecessary time waste. The first blade allows for faster and more efficient cutting of wires, and the clamping teeth can clamp the wire to be stripped. The second blade and cross-shaped cutting head provide workers with more diverse tools, improving their work efficiency and reducing unnecessary time waste.
[0015] 2. This utility model proposes a handheld wire stripper. When the wire is clamped by the cutting ring, pressing the sliding pin causes the sliding pin to drive the limiting block downward to squeeze the spring, causing the sliding block to move outward while the steel ball retracts inward to disengage from the locking groove. When the wire is clamped to the appropriate size by the cutting ring, the sliding pin can be released to drive the steel ball to engage with the locking groove. This mechanism can reduce the workload of the operator, allowing the operator to avoid constantly gripping the handle, making the work more convenient and improving the efficiency of the worker.

[0023] Working principle: When the device is needed, controlling the first handle 202 and the second handle 203 causes the second rotating block 107 and the first rotating block 106 to move the first fixed block 101 and the second fixed block 108, so that the wire to be stripped matches the cutting rings 104 of different sizes. Then, the excess wire is cut by the cutting rings 104. The first blade 103 can cut the wire to be stripped, and the clamping teeth 102 can clamp the wire to be stripped. When the second blade 109 needs to be used, the baffle 1017 can be opened and the first connecting rod 1010 can be pulled to drive the second blade 109 to rotate via the second rotating column 1011. When the cross blade 1012 needs to be used, the baffle 1017 can be opened and the first connecting rod 1010 can be pulled to rotate the second blade 109. The second connecting rod 1013 causes the cross head 1012 to rotate via the third rotating column 1014. When clamping the wire, the sliding column 204 can be pressed to cause the limiting block 207 to press the spring 208 downward. The sliding column 204, through the spring 208, causes the sliding block 2010 to move outward. As the sliding block 2010 moves outward, the steel ball 205 will retract inward and disengage from the locking groove 2012. After the wire is clamped to the appropriate size by the shearing ring 104, the sliding column 204 can be released to cause it to rebound through the spring 208. When the sliding column 204 rebounds, it will cause the sliding block 2010 to retract inward. When the sliding block 2010 retracts inward, it will cause the steel ball 205 to engage with the locking groove 2012. The baffle 1017 is fixed by damping.
