In the above-mentioned scheme, the first step of the method,

the back parts of the movable left jaw tongue and the movable right jaw tongue are connected with a tension spring connected with the middle handle.

The front ends of the left turn knob and the right turn knob are screw rods which are screwed into the middle handle, and the left supporting arm and the right supporting arm are connected with the screw rods through notches on the side surfaces of the middle handle.

And slotted holes for inserting the left supporting arm and the right supporting arm are processed between the left handle structure and the right handle structure.

The utility model has the advantages that: 1. according to the principle of common pliers, the jaws of the clamp are provided with two jaws according to the outer diameter sizes of the lead and the lead, so that the clamp can be clamped on the lead and the lead, and the requirement of live connection of the lead of various 10kV wire clamps is met.

2. The middle of the handle structure of the common pliers is provided with the slotted hole for inserting the supporting arm (the slotted hole is processed in the middle for fixing the left supporting arm and the right supporting arm, the structure is compact in structure and the whole weight is reduced), the structure of the spring and the left and right supporting arms is utilized, the installation and the fixation are convenient, the fixture is prevented from being displaced after being stressed in the use process, meanwhile, the two points are also used as fixed stress points of the fixture (see the left supporting arm, the right supporting arm and the tension spring in figure 1), and the tension born by an operator can be transferred under the condition that the original stress mode is not changed.

3. The structure is simple and reasonable, and the use is safe and reliable; the problem that no special fixture is arranged on the lead of the 10KV common wire clamp is solved.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Detailed Description

Referring to fig. 1-3, the part names are as follows: the device comprises a middle handle 1, a left jaw tongue 2, a right jaw tongue 3, a movable left jaw tongue 4, a movable right jaw tongue 5, a left handle 6, a right handle 7, a left supporting arm 8, a right supporting arm 9, a left turn knob 10, a right turn knob 11, a tension spring 12, a screw 13, a notch 14, a left jaw 15, a right jaw 16 and an oval groove hole 17.

Referring to fig. 1-3, a 10kv internal fast wiring double-port wire clamp comprises a middle handle 1, wherein a left clamp tongue 2 and a right clamp tongue 3 (with a wire biting radian and clamping teeth) which are inclined left and right are fixed at the front end of the middle handle 1; two movable left jaw tongues 4 and movable right jaw tongues 5 (with biting line radian and clamping teeth) are respectively hinged on two sides of the front end of the middle handle 1 corresponding to the left jaw tongue 2 and the right jaw tongue 3 to form a left jaw and a right jaw (a left jaw 15 and a right jaw 16). The rear parts of the movable left jaw tongue 4 and the movable right jaw tongue 5 are hinged with a left handle 6 and a right handle 7, and the left handle 6 and the right handle 7 are respectively connected with a left rotary knob 10 and a right rotary knob 11 in the middle handle 1 through a left supporting arm 8 and a right supporting arm 9.
