Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown:

[0021] Embodiment 1: The utility model provides an insulating pliers for live working in electric power construction, comprising: an insulating pliers mechanism 1, comprising an insulating pliers body 11, a limiting slide groove 12 provided on the inner side of the clamping end of the insulating pliers body 11, and a support ring 13 fixedly connected to the outer side of the clamping end of the insulating pliers body 11; a needle-nosed pliers mechanism 2, comprising a needle-nosed pliers assembly 21 that is limitedly slidably embedded in the limiting slide groove 12, and a spring 22 connected to the needle-nosed pliers assembly 21, the spring 22 can drive the needle-nosed pliers assembly 21 to sink into the clamping end of the insulating pliers body 11; a positioning mechanism 3 embedded in the support ring 13, the positioning mechanism 3 can position the needle-nosed pliers assembly 21;

[0022] Among them, when the needle-nosed pliers assembly 21 is needed, the clamping end of the insulating pliers body 11 is unfolded, and the needle-nosed pliers assembly 21 is pulled to extend out of the clamping end of the insulating pliers body 11. When the needle-nosed pliers assembly 21 moves, the spring 1 22 will be compressed in the limiting slide groove 12. When the needle-nosed pliers assembly 21 moves to the extreme position, the positioning mechanism 3 will position the needle-nosed pliers assembly 21, so as to facilitate the staff to use the needle-nosed pliers assembly 21. After use, after pulling the positioning mechanism 3, the needle-nosed pliers assembly 21 will be reset and retracted into the clamping end of the insulating pliers body 11 under the push of the spring 1 22.

[0023] Specifically, the needle-nosed pliers assembly 21 includes a needle-nosed pliers body 211 , one side of the needle-nosed pliers body 211 is fixedly connected to a T-shaped slider 212 , the other side of the needle-nosed pliers body 211 is fixedly connected to a stripe 213 , and a positioning slot 214 is also provided on the T-shaped slider 212 .

[0024] Specifically, the needle-nosed pliers body 211 is limitedly slidably embedded in the limiting slide groove 12 through a T-shaped slider 212, a spring 22 is fixedly connected to the T-shaped slider 212, and the spring 22 drives the T-shaped slider 212 to move toward the handle direction of the insulating pliers body 11.

[0025] As can be seen from the above, the needle-nosed pliers body 211 slides inside the limiting slide groove 12 through the T-shaped slider 212, thereby playing a guiding role. The strip pattern 213 can facilitate the staff to move the position of the needle-nosed pliers body 211, while ensuring the stability of the clamping of the needle-nosed pliers body 211.

[0026] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the positioning mechanism 3 includes a positioning pin 31 and a spring 32, a push ring 33 is fixedly connected to the outer side of the positioning pin 31, and a connecting ball 34 is also fixedly connected to one end of the positioning pin 31.

[0027] Specifically, the second spring 32 is sleeved on the outer side of the positioning pin 31 , and the positioning pin 31 is slidably embedded in the support ring 13 .

[0028] Specifically, the second spring 32 is located between the support ring 13 and the push ring 33 , and the positioning pin 31 can be embedded in the positioning slot 214 .

[0029] As can be seen from the above, when the needle-nosed pliers body 211 drives the T-shaped slider 212 to slide to the extreme position inside the limiting slide groove 12, the push ring 33 will drive the positioning pin 31 to embed into the positioning slot 214 under the drive of the spring 2 32, so that the position of the needle-nosed pliers body 211 is fixed. When the positioning needs to be released, the connecting ball 34 is pulled to make the positioning pin 31 disengage from the positioning slot 214, and the T-shaped slider 212 will also slide inside the limiting slide groove 12 under the push of the spring 1 22, and the needle-nosed pliers body 211 is retracted into the clamping end of the insulating pliers body 11.
