Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1 Please see Figures 1-4 The multi-functional electrician's pliers shown in the figure include a first handle 101 and a second handle 102, and a first plier head 103 and a second plier head 104 respectively disposed at one end of the first handle 101 and the second handle 102. The first handle 101 and the second handle 102 are hollow on opposite sides. The pliers also include a serrated clamping surface 2, a stripping groove 3, and a cutting edge 4 disposed on the first plier head 103 and the second plier head 104. The serrated clamping surface 2 is located at the front end of the plier head, and the inner side of the jaws is designed with staggered serrated patterns to increase friction. The stripping groove 3 has a V-shaped groove at the rear of the plier head to adapt to the stripping of insulation layers of wires with different diameters. The cutting edge 4 is located at the rear end of the plier head, with a cutting edge angle of 15°, and is used to cut wires and cable ties. The first handle 101 is provided with a detection component for detecting the electric field of the line. The first handle 101 and the second handle 102 are provided with adjustment components for adjusting the use angle of the first plier head 103 and the second plier head 104. It should be noted that by incorporating the serrated gripping surface 2, wire stripping groove 3, and cutting edge 4 at the pliers head, cutting, wire stripping, and wire crimping functions are integrated into a single tool, reducing the burden of carrying tools and improving work efficiency. Simultaneously, the detection component provides real-time warnings of live lines, thereby reducing the risk of electric shock and enhancing the safety of using the electrician's pliers. Furthermore, the adjustable component allows the pliers head angle to adapt to the needs of working in narrow spaces such as cable trenches, further improving the flexibility of the electrician's pliers. Therefore, the high degree of functional integration and the combined effect of the detection and adjustment components enhance the versatility of the electrician's pliers.

[0015] Please see Figure 1 The detection components shown in the figure include a non-contact electric field sensor 501 and a buzzer 502 disposed in the hollow part of the first handle 101. A dual-color LED indicator 503 is provided on one side of the first handle 101. The non-contact electric field sensor 501 is electrically connected to the buzzer 502 and the dual-color LED indicator 503. It should be noted here that by setting up the detection component, real-time warnings of live lines are provided, thereby reducing the risk of electric shock accidents and improving the safety of using electrician's pliers.

[0016] Working principle: When in use, this electrician's pliers can clamp the cable with the saw teeth under the clamping action of the first pliers head 103 and the second pliers head 104. The V-shaped groove of the stripping groove 3 can be used to strip the insulation layer of wires of different diameters. The cutting edge 4 can also be used to cut the wires and cable ties. Thus, the functions of cutting, stripping and crimping are integrated into a single tool, reducing the burden of carrying tools and improving work efficiency. Meanwhile, during use, the electrician's pliers can use a non-contact electric field sensor 501 based on the principles of electrostatic induction or electromagnetic induction to detect changes in the spatial electric field strength to determine the presence and state of a live conductor. If the line is energized, an alarm will be triggered by a buzzer 502 and a dual-color LED indicator 503, thus providing real-time warning of energized lines and reducing the risk of electric shock accidents, thereby improving the safety of using the electrician's pliers.

[0017] Example 2 Please see Figure 3 This embodiment further illustrates Example 1. The adjustment component shown in the figure includes a rotating shaft 601 rotatably connected to one end of the first handle 101 near the first clamp head 103. One end of the rotating shaft 601 is fixedly connected to an adjustment tube 603. A fixing hole 602 is provided on the side of the first handle 101 near the adjustment tube 603. The adjustment tube 603 is rotatably connected to the fixing hole 602. A spline hole 604 is provided at the bottom of the adjustment tube 603. A spline plate 605 is slidably connected to the spline hole 604. The first handle 101 is provided with a drive component for driving the spline plate 605. It should be noted that by adjusting the component settings, when it is necessary to adjust the angle of use of the first clamp head 103 and the second clamp head 104, by pulling the T-shaped drive rod 702 (which can close the first handle 101 and the second handle 102, thereby achieving synchronous pulling of the two T-shaped drive rods 702), the spline plate 605 will be moved synchronously during the pulling of the T-shaped drive rod 702, thereby causing the spline plate 605 to separate from the spline hole 604, thus releasing the connection limit between the first clamp head 103, the second clamp head 104 and the first handle 101 and the second handle 102. At this time, the first clamp head 103 and the second clamp head 104 can be rotated, thereby realizing the adjustment of the angle of use of the first clamp head 103 and the second clamp head 104, making the clamp head angle adaptable to the needs of working in narrow spaces such as cable troughs, thereby improving the flexibility of use of the electrician's pliers.

[0018] Please see Figure 2 and Figure 3 The drive assembly shown in the figure includes an L-shaped plate 701 fixedly connected to the side of the first handle 101 near the fixing hole 602. The L-shaped plate 701 is connected to a T-shaped drive rod 702 through a keyway and a key pin. One end of the T-shaped drive rod 702 is connected to the spline plate 605. It should be noted here that the settings of the drive component are used to disconnect the spline plate 605 from the spline hole 604.

[0019] Please see Figure 2 and Figure 3The T-shaped drive rod 702 in the figure is fitted with a spring 703 on the side wall inside the adjusting tube 603. The two ends of the spring 703 are connected to the inner wall of the adjusting tube 603 and the spline plate 605, respectively. It should be noted here that the spring 703 is used to provide elastic reset for the spline plate 605.

[0020] Example 3 Please see Figure 4 This embodiment is a further explanation of other embodiments. In the figure, a plurality of auxiliary tools 8 are rotatably connected to the second handle 102 via a mounting rod. The second handle 102 is provided with a magnetic suction piece for magnetically attracting each auxiliary tool 8. It should be noted that by setting up multiple auxiliary tools 8, the burden of carrying tools is reduced and work efficiency is improved. At the same time, the use of magnetic plates to magnetically fix each auxiliary tool 8 can reduce the risk of tools falling off.
