[0020] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0021] like Figures 1-8 As shown, this utility model discloses a pair of needle-nose pliers with an electrical testing function, comprising: The first clamp body 1 is made of conductive materials such as alloys.

The second clamp body 2 includes, from top to bottom, a second pointed tip 21, a second hinge part 22 and a second handle part 23. The first hinge part 12 and the second hinge part 22 are hinged together by accessories such as pins. The first insulating element 3 is sleeved on the outer periphery of the first handle 13; The second insulating element 4 is sleeved on the outer periphery of the second handle 23; The electrical testing module 5 is assembled on the first insulating component 3. The electrical testing module 5 is provided with a first contact portion 511 and an outer contact portion 523. The first contact portion 511 is electrically connected to the first handle portion 13, and the outer contact portion 523 is located on the outer surface of the first insulating component 3. The first pointed tip 11 is used to contact the object being tested.

[0022] Therefore, 1. The user operates the first tip 11 and the second tip 21 to open or close by holding the first insulating member 3 and the second insulating member 4 to perform the corresponding work; 2. When it is necessary to test the electrical properties of the object being tested, the user holds the first insulating member 3 and places his / her fingers on the outer contact part 523, and then puts the first tip 11 into contact with the object being tested. The display of the electrical testing module 5 is used to determine whether the object being tested is charged. It should be noted that because the first tip 11 is set with a pointed tip, the first tip 11 can be inserted into narrow spaces such as sockets to test the electrical properties.

[0023] Specifically, the electrical measurement module 5 includes a light-emitting part 51 and an elastic sheet 52. The light-emitting part 51 can be connected in series with a neon tube or an LED lamp by a large resistor of 1-2MΩ. The large resistor ensures the safety of the electrical measurement, and the light emitted by the neon tube or LED lamp is used to identify whether the object being measured is charged. The light-emitting part 51 is cylindrical, with a first contact part 511 located at the upper end of the light-emitting part 51 and a second contact part 512 located at the lower end of the light-emitting part 51. The elastic sheet 52 is formed by stamping and bending. In this embodiment, the outer contact part 523 is part of the structure of the elastic sheet 52. The elastic sheet 52 also includes an elastic abutment part 521 and a fixing part 522. The fixing part 522 fixes the elastic sheet 52 to the first insulating member 3, while the elastic abutment part 521 deforms and abuts against the second contact part 512, thereby electrically connecting the second contact part 512 and the elastic sheet 52.

[0024] Therefore, when the object being tested is charged, the current flows sequentially through the first clamp 1, the first contact part 511, the light-emitting part 51, the second contact part 512, the elastic abutment part 521, the fixing part 522, the external contact part 523, and then to the human body.

[0025] In other embodiments, the outer contact portion 523 may also be fixed to the elastic sheet 52 by welding, snap-fitting, or other methods.

[0026] Specifically, in this embodiment, the first insulating member 3 includes an insulating sleeve 31 and a mounting base 32; wherein, the insulating sleeve 31 is provided with a through hole 311, an insertion opening 312 at the upper end of the through hole 311, and a mounting area 313 at the lower end of the through hole 311, the first handle 13 is inserted into the through hole 311 from top to bottom through the insertion opening 312, and partially passes through the through hole 311 to the mounting area 313; the light-emitting part 51 is located in the mounting area 313, and the mounting base 32 is assembled on the insulating sleeve 31 to close the mounting area 313; wherein, the insulating sleeve 31 and / or the mounting base 32 are made of a light-transmitting material, the insulating sleeve 31 in this embodiment is made of opaque silicone material, and the mounting base 32 is made of light-transmitting plastic material.

[0027] Furthermore, the fixing part 522 is provided with a round fixing hole 5221, the insulating sleeve 31 is provided with a plug hole 314, and the mounting base 32 is provided with a protruding plug post 321. When the insulating sleeve 31 and the mounting base 32 are assembled, the plug post 321 passes through the fixing hole 5221 and the plug hole 314 in sequence so that the fixing part 522 is clamped and fixed between the insulating sleeve 31 and the mounting base 32, thereby ensuring the stability of the elastic sheet 52 installation.

[0028] Furthermore, the mounting base 32 is provided with a clamping part 322 that clamps the outer periphery of the light-emitting part 51, so that the elastic piece 52 is first installed through the cooperation of the fixing hole 5221 and the plug post 321, and then the light-emitting part 51 is clamped and installed in the clamping part 322. Finally, the elastic piece 52 and the light-emitting part 51 are installed together with the mounting base 32 on the insulating sleeve 31, making the assembly more convenient.

[0029] Furthermore, the insulating sleeve 31 is provided with assembly rails 315 on both sides of the mounting base 32, and the mounting base 32 is provided with corresponding assembly slides 325 on both sides, so that the assembly rails 315 and the assembly slides 325 slide and cooperate to allow the insulating sleeve 31 and the mounting base 32 to move closer or separate. In addition, the mounting base 32 is provided with a snap-fit ​​part 326. When the insulating sleeve 31 and the mounting base 32 move closer and abut against each other, the snap-fit ​​part 326 snaps onto the insulating sleeve 31 to restrict the relative sliding of the assembly rails 315 and the assembly slides 325, thereby completing the fixed assembly of the first insulating component 3.

[0030] Preferably, the outer contact 523 includes a first contact 5231 and a second contact 5232. The first contact 5231 is located on the lower end face of the insulating sleeve 31, and the second contact 5232 is located on the outer peripheral surface of the lower end of the insulating sleeve 31. This allows the user to make use more convenient by contacting the first contact 5231 and / or the second contact 5232.

[0031] One end of the first contact 5231 is connected to the fixing part 522, and the other end of the first contact 5231 is connected to the lower end of the second contact 5232. The upper end of the second contact 5232 is bent to form a hook part 524. Correspondingly, the outer surface of the insulating sleeve 31 is provided with a hook groove 316. The hook part 524 is fitted into the hook groove 316, so that the stability of the elastic sheet 52 is further improved by the cooperation of the hook groove 316 and the hook part 524.

[0032] A first clamping area 61 is provided between the upper parts of the first pointed tip 11 and the second pointed tip 21. Both the first pointed tip 11 and the second pointed tip 21 are provided with a first corrugated section 611 in the first clamping area 61. When the first pointed tip 11 and the second pointed tip 21 are closed, the two first corrugated sections 611 are arranged to abut each other, so as to achieve basic and stable clamping through the first clamping area 61.

[0033] The first pointed tip 11 and the second pointed tip 21 are located below the first clamping area 61 and a second clamping area 62 is provided. The first pointed tip 11 and the second pointed tip 21 are both provided with second corrugated sections 621 in the second clamping area 62. When the first pointed tip 11 and the second pointed tip 21 are closed, the two second corrugated sections 621 are non-contact and a clamping space 622 is formed between the two second corrugated sections 621, so that small screws can be clamped and tightened through the second clamping area 62.

[0034] A stripping area 63 is provided between the first pointed tip 11 and the second pointed tip 21 below the second clamping area 62. Multiple concave arc blades 631 are arranged vertically on both the first pointed tip 11 and the second pointed tip 21 in the stripping area 63. When the first pointed tip 11 and the second pointed tip 21 are closed, the concave arc blades 631 are paired together, and a stripping hole 632 is formed between the paired concave arc blades 631. The size of each concave arc blade 631 gradually increases from top to bottom, so that the size of the formed stripping hole 632 gradually increases from top to bottom, so that wires of different sizes can be stripped by rotating the outer periphery through different stripping holes 632.

[0035] Among them, a shearing area 64 is provided between the first tip 11 and the second tip 21 below the stripping area 63. Both the first tip 11 and the second tip 21 are provided with shearing blades 641 in the shearing area 64. When the first tip 11 and the second tip 21 are closed, the two shearing blades 641 are in a shearing state so that shearing can be performed through the shearing blades 641.

[0036] A terminal pressing area 71 is provided between the first handle 13 and the second handle 23. The first tip 11 and the second tip 21 are respectively provided with a terminal pressing groove 711 and a terminal pressing protrusion 712 in the terminal pressing area 71.

When the first tip 11 and the second tip 21 are closed, the first wire splitting groove 721 and the second wire splitting groove 722 are joined together so that the wire can be cut and split along the length direction in the wire splitting area 72.

[0038] The first handle 13 and / or the second handle 23 are provided with four matrix-arranged winding holes 73 for winding.

[0039] Among them, a locking member 8 is rotatably provided on the second handle 23 by means of a pin or the like, and a locking latch 121 is provided on the first hinge part 12; When the first pointed tip 11 and the second pointed tip 21 are closed, the locking member 8 flips over and engages with the locking latch 121 to prevent the first pointed tip 11 and the second pointed tip 21 from separating.
