Description

Technical Field

[0001] This application relates to the technical field of electrical tools, and in particular to a multi-functional electrician's pliers. Background Technology

[0002] An electrician is a person engaged in industrial production systems such as power generation, electrical manufacturing, electrical maintenance, and construction installation. Electricians use a variety of tools, among which electrician's pliers are one. Electrician's pliers are also called vise pliers. When performing electrical engineering work, workers often use electrician's pliers. As one of the most commonly used and essential tools in electrical engineering, electrician's pliers can be used to tighten screws, bend stranded wires, cut wires, and side-cut wires.

[0003] A search revealed a utility model of multifunctional electrician's pliers with publication number CN216940204U. The pliers include a pliers body and pliers heads. The pliers body includes a clamping pin and left and right handles hinged together by the clamping pin. Both the left and right handles have a fixed anti-slip insulating layer on their handle surfaces. The left handle has a groove on its left side wall containing a folding knife, and the right handle has a groove on its right side wall containing a folding voltage tester. The pliers heads include a left and right pliers head, detachably connected to the pliers body. Both the left and right pliers heads have corresponding serrated jaws and semi-circular wire stripping edges. A flashlight is mounted on the side of the left and / or right pliers head, comprising an LED light and a battery to power the LED light. This utility model integrates the functions of ordinary pliers, wire strippers, a knife, a voltage tester, and a flashlight, reducing the number of tools electricians need to carry in their daily work and lightening their load.

[0004] Traditional wire strippers rely on the stripping holes to strip wires, and can only strip cables with matching hole diameters. Usually, a single wire stripper cannot have stripping holes that fit all cables at the same time, which makes traditional wire strippers quite limited in use. They cannot strip cables with mismatched hole diameters, affecting the normal work progress and reducing work efficiency. Utility Model Content

[0005] In order to strip cables of different diameters and improve the efficiency of electrician's pliers, this application provides a multi-functional electrician's pliers.

[0006] This application provides a multi-functional electrician's pliers, which adopts the following technical solution: A multi-functional electrician's pliers includes a pair of hinged pliers heads and a handle mounted on the two pliers heads for easy hand gripping. A jaw is provided on one side of the two pliers heads that is close to each other and away from the hinge point. A cutting edge for cutting cables is provided on both pliers heads near the lower part of the jaw. A wire stripping device is provided on the pliers head between the jaw and the cutting edge, capable of stripping cables of different diameters. The wire stripping device includes a pair of stripping discs rotatably mounted on the two pliers heads and stripping openings of different diameters on the stripping discs. The two stripping discs and the two opposite stripping openings cooperate with each other.

[0007] By adopting the above technical solution, when stripping cables, two corresponding stripping discs can be rotated to make the stripping openings on the stripping discs correspond to each other, and then the cables can be stripped. By rotating the stripping discs, stripping openings of different diameters can be set on the stripping discs. Furthermore, the annular stripping discs can be set with more stripping openings of different diameters without occupying a long length of the pliers, saving space on the pliers and allowing for other structures.

[0008] Preferably, clearance openings are provided on the adjacent sides of the two pliers heads at the contact points of the two wire stripping discs.

[0009] By adopting the above technical solution, the clearance opening allows the cable to be stripped to be placed in the clearance opening, avoiding the two pliers from squeezing the cable, while allowing the two stripping discs to operate better and strip the cable.

[0010] Preferably, a rotating shaft is fixed at the axis of the wire stripping disc, and the end of the rotating shaft is rotatably fitted onto the corresponding pliers head.

[0011] By adopting the above technical solution, the wire stripping blade fixed on the rotating shaft can rotate better and facilitate the rotation of the wire stripping blade.

[0012] Preferably, the rotating shaft passes horizontally through the pliers head, and a rotating block is fixed at the end of the rotating shaft away from the wire stripper disc to facilitate rotation by the user.

[0013] By adopting the above technical solution, users can adjust the wire stripping disc by driving the rotating block to rotate, avoiding direct rotation of the wire stripping disc and potential hand injuries.

[0014] Preferably, the wire stripping device further includes a fixing component disposed on the pliers head and corresponding to the wire stripping disc. The fixing component is used to fix the rotated wire stripping disc. The fixing component includes a fixing rod slidably disposed on the pliers head and a fixing ring fixed on the rotating shaft. The fixing ring has multiple fixing grooves on its circumferential surface, and the end of the fixing rod is slidably inserted into the fixing groove.

[0015] By adopting the above technical solution, and through the fixing groove on the fixing rod and fixing ring, when the wire stripper disc is rotated and adjusted, the end of the fixing rod can be inserted into the fixing groove, thereby preventing the two wire stripper discs from rotating during use.

[0016] Preferably, the fixing assembly further includes a clamping spring on the clamp head, the clamping spring being disposed at the end of the fixing rod away from the fixing ring, and the end of the fixing rod abutting against the clamping spring, so that the clamping spring presses the end of the fixing rod against the fixing groove.

[0017] By adopting the above technical solution, the outer convex surface of the clamping spring is pressed against the end of the fixing rod and the fixing rod is always pressed against it, so that the end of the fixing rod is always in the fixing groove, thus preventing the end of the fixing rod from sliding out of the wire stripping disc during the wire stripping process and causing the wire stripping disc to rotate.

[0018] Preferably, the fixing rings on both sides of the fixing groove are provided with rounded corners, so that the end of the fixing rod can slide through the rounded corners of the fixing groove.

[0019] By adopting the above technical solution, the wire stripper disc can smoothly slide between the fixed rod and the fixed ring during rotation due to the rounded corners. Furthermore, when the rotating block is driven to rotate, the end of the fixed rod is automatically pushed outward, making the rotation adjustment of the wire stripper disc smoother.

[0020] Preferably, a fixing bolt is threaded onto the fixing rod, the fixing bolt passes vertically through the fixing rod, and the end of the fixing bolt is threadedly connected to the pliers head.

[0021] By adopting the above technical solution, after the wire stripper disc is adjusted, tighten the fixing bolts to prevent the fixing rod from sliding, so that the two wire stripper discs will not rotate during use, thus avoiding injury to the operator.

[0022] Preferably, the fixing rod has a sliding hole along its length, the fixing bolt passes through the sliding hole, and the fixing rod slides with the fixing bolt as the fixing point.

[0023] By adopting the above technical solution, when the wire stripper disc rotates, the fixing rod slides away from the fixing ring, so that the fixing bolt slides in the sliding hole. After the fixing rod has slid, the fixing bolt is tightened, avoiding the need to repeatedly unscrew the fixing bolt from the pliers.

[0024] Preferably, a pair of parallel guide rods are fixed on the pliers head, with the two guide rods located on both sides of the fixed rod, and the fixed rod slidingly engaged between the two guide rods.

[0025] By adopting the above technical solution, when rotating and adjusting the wire stripper disc, the fixing rod can slide in the vertical direction, thus preventing the end of the fixing rod from failing to be accurately inserted into the fixing groove.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The electrician's pliers provided in this application integrate multiple functions and can be used for various operations during construction. In particular, when stripping cables, the stripper disc can be rotated to adjust the cutting edge on the stripper disc to a suitable diameter before stripping the cable. The stripper disc has a large number of stripping openings to choose from, thus it can adapt to a wider range of applications. 2. By setting the wire stripper disc to rotate, the space occupied on the pliers head is reduced, so the saved space can be used for other necessary structures, making the electrician's pliers more versatile; 3. The wire stripper disc can be adjusted more easily by using the clamping spring and fixing bolts. After adjustment, it can be fixed with the fixing bolts to prevent the wire stripper disc from rotating during use. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a multifunctional electrician's pliers.

[0034] Reference Figure 1 A multi-functional electrician's pliers includes a pair of hinged pliers 1, which are arranged crosswise with the hinge point close to one end of each pliers 1. A hinge shaft 11 passes through the hinge point of the two pliers 1 and through the two pliers 1. A handle 12 is fixed at the end of each pliers 1 near the hinge point, and the length direction of the handle 12 is the same as that of the pliers 1, allowing the user to grip the pliers easily. A jaw 13 for clamping cables is provided on the side of the two pliers 1 that is close to each other and away from the hinge point. A clamping part for clamping cables is provided at the end of the jaw 13 near the pliers 1. A cutting edge 14 for cutting cables is provided on each pliers 1 near the jaw 13. In use, different positions are selected according to the cable to be operated.

[0035] Reference Figure 1 and Figure 2 The cable stripping tool 15 is provided on both pliers 1 near the hinge point. A wire-stripping notch is provided on the side of one pliers 1 away from the other. Multiple hexagonal nut-tightening notches with different diameters are provided on the side of the other pliers 1 for tightening different nuts. A winding notch 16 and a branching notch 17 are located on the other end of both pliers 1 near the handle 12. A cable-clamping mechanism is provided on the side of both pliers 1 near the handle 12, where the pliers 1 are close to each other. Alternatively, a clamping clip can be installed; a safety lock 18 is provided at the hinge point of the two pliers 1, which fixes the two pliers 1. When not in use, the installation lock can be rotated to prevent the two pliers 1 from rotating apart; multiple grinding holes 19 of different sizes are provided on the surface of one of the pliers 1 at the hinge point, and the multiple grinding holes 19 are evenly arranged around the hinge axis 11. The other pliers 1 is provided with grinding grooves. When dealing with screws, bolts or bolts with worn ends or burrs, they can be inserted into the grinding holes 19 and then ground to remove the burrs before use.

[0036] A wire stripping device 2 is provided on the pliers head 1 between the jaws 13 and the cutting edge 14. Relief openings 21 are provided on both sides of the two pliers head 1 that are close to each other. The wire stripping device 2 includes a pair of wire stripping blades 22 rotatably mounted on the pliers head 1 and located at the relief openings 21. The two wire stripping blades 22 have the same diameter, and their edges are in contact with each other, with sharp blades at the edges to facilitate wire stripping. The relief openings 21 allow the cable to be stripped to be placed in the relief openings 21, preventing the two pliers head 1 from squeezing the cable. Multiple stripping blades for removing the cable sheath are provided on the two wire stripping blades 22 along their edges. The stripping ports 221 are evenly arranged around the circumference of the stripping disc 22, and the diameters of the multiple stripping ports 221 are different, so as to be used to strip cables of different diameters, thereby improving the utilization rate of the equipment. By setting the stripping device as a rotating stripping disc 22, the problem of not being able to set multiple stripping ports 221 of different diameters on the clamp head 1 is avoided, and they do not need to be arranged in a straight line. Therefore, cables of different diameters can be stripped. In addition, the stripping disc 22 does not occupy a large space, which can save space on the clamp head 1 to set up a structure with other functions. In this application, the saved space is set up as a stripping component 15 that can slide open and strip cables of different diameters. The thicker diameter cable can be placed at the position of the stripping component 15, and one side of the cable can be slid open by the blade, and then stripped from the cable, and finally the outer sheath of the cable can be cut.

[0037] Reference Figure 1 , Figure 3 and Figure 4 A rotating shaft 222 is fixedly installed along the axis of the wire stripper disc 22. The wire stripper disc 22 is located at the end of the rotating shaft 222, and the structure between the wire stripper disc 22 and the rotating shaft 222 is designed for easy disassembly, so that different wire stripper discs 22 can be replaced. Different wire stripper discs 22 can have different numbers of stripping holes 221 or stripping holes 221 of different diameters. The rotating shaft 222 passes horizontally through the pliers head 1 and is rotatably fitted onto the pliers head 1. By rotating the wire stripper disc 22, it is easy to select stripping holes 221 of different diameters. At the other end of the rotating shaft 222 and on the other side of the pliers head 1 relative to the wire stripper disc 22, a rotating block 223 is fixed to control the rotation of the wire stripper disc 22. The user can adjust the wire stripper disc 22 by driving the rotating block 223 to rotate, avoiding direct rotation of the wire stripper disc 22 and cutting the hands.

[0038] A fixing assembly 23 is provided on the pliers head 1 and at the position corresponding to each wire stripper disc 22 to fix the wire stripper disc 22. It includes a fixing rod 231 slidably disposed on the side of the pliers head 1. The length direction of the fixing rod 231 is perpendicular to the rotation shaft 222 and the length direction of the fixing rod 231 is the same as the length direction of the pliers head 1. A fixing ring 232 is fixed on the rotation shaft 222 and on the side close to the pliers head 1. The fixing ring 232 is located between the pliers head 1 and the rotating block 223. The diameter of the fixing ring 232 is smaller than the diameter of the rotating block 223. Multiple fixing grooves 233 are formed on the circumference of the fixing ring 232. The end of the fixing rod 231 can be slidably inserted into the fixing groove 233. The number of fixing grooves 233 is the same as the number of stripping openings 221 on the wire stripper disc 22 and they correspond one-to-one. This makes it convenient for the user to determine that the stripping openings 221 on the two wire stripper discs 22 are aligned and that the wire stripper disc 22 has rotated to the correct position during rotation.

[0039] Reference Figure 1 , Figure 3 and Figure 4 A clamping spring 234 is provided on the pliers head 1 at a position on the fixing rod 231 away from the fixing ring 232. The clamping spring 234 is arc-shaped, and its outer convex surface abuts against the end of the fixing rod 231, keeping it firmly pressed against the fixing rod 231. This ensures that the end of the fixing rod 231 is always in the fixing groove 233, preventing the end of the fixing rod 231 from sliding off the wire stripping disc 22 during wire stripping and causing the wire stripping disc 22 to rotate. A pair of fixing blocks 235 are fixed on the pliers head 1. The two fixing blocks 235 are located at both ends of the clamping spring 234, and the two ends of the clamping spring 234 are inserted into and fitted onto the fixing blocks 235, thereby allowing the clamping spring 234 to be replaced. The fixed ring 232 and the position where the fixed groove 233 contacts the fixed rod 231 are all rounded. During the rotation of the wire stripper disc 22, the fixed rod 231 and the fixed ring 232 can slide smoothly. When the drive rotating block 223 rotates, the end of the fixed rod 231 is automatically pushed outward, making the rotation adjustment of the wire stripper disc 22 smoother.

[0040] Reference Figure 1 , Figure 3 and Figure 4A fixing bolt 24 is threaded onto the fixing rod 231. After the wire stripper disc 22 is adjusted, the fixing bolt 24 is tightened to prevent the fixing rod 231 from sliding, thus preventing the two wire stripper discs 22 from rotating during use and avoiding injury to the operator. The fixing bolt 24 passes vertically through the fixing rod 231, and the end of the fixing bolt 24 is threaded onto the pliers head 1, thereby fixing the sliding fixing rod 231. A sliding hole 25 is provided on the fixing rod 231 along its length. The fixing bolt 24 passes through the sliding hole 25, and the two can slide relative to each other. When the wire stripper disc 22 rotates, the fixing rod 231 slides away from the fixing ring 232, so that the fixing bolt 24 slides in the sliding hole 25. After the fixing rod 231 has slid, the fixing bolt 24 is tightened again to avoid having to repeatedly unscrew the fixing bolt 24 from the pliers head 1. A pair of parallel guide rods 26 are fixed on the side of the pliers head 1. The length direction of the two guide rods 26 is the same as the length direction of the fixed rod 231, and the two guide rods 26 are symmetrically arranged on both sides of the fixed rod 231. The fixed rod 231 is slidably arranged between the two guide rods 26. When the wire stripper disc 22 is rotated and adjusted, the fixed rod 231 can slide in the vertical direction to prevent the end of the fixed rod 231 from being unable to be accurately inserted into the fixed groove 233.

[0041] The implementation principle of a multi-functional electrician's pliers according to an embodiment of this application is as follows: When stripping cables of different diameters, the operator can rotate and adjust the wire stripping disc 22 to adjust the stripping opening 221 on the wire stripping disc 22 to the corresponding position. The rotated wire stripping disc 22 can be fixed by the fixing rod 231 and the fixing bolt 24 so that the wire stripping disc 22 will not rotate during use.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
