Abstract
The invention provides a pair of three-leg pliers. The three-leg pliers comprise a first pliers leg, a second pliers leg and a third pliers leg; the first pliers leg, the second pliers leg and the third pliers leg are fixed by a pin shaft, and the first pliers leg, the second pliers leg and the third pliers leg are able to rotate around each other; one ends of the first pliers leg, the second pliers leg and the third pliers leg constitute a first vice jaw working area and a second vice jaw working area; the other ends of the first pliers leg, the second pliers leg and the third pliers leg are grabbing sections. The pair of three-leg pliers is provided with two vice jaw movable areas, and three grabbing portions, therefore two objects can be clamped at the same time with one hand, thereby avoiding potential safety hazard such as electric leakage caused by that the clamped object is released due to frequently changing the use hand when the wireman of the prior art is doing a hot-line work. The safety of hot-line work is increased.
Description
Technical field
The present invention relates to a kind of electrician tool, particularly relate to a kind of pliers.
Background technology
In field power supply erection in construction site is installed, normal needs carry out live line connection to unfixed two wires mutually, the insulation of the usual first strip off of electrician two lines, then with left and right two pairs of pliers, two lines are costed energising, vacate after left pliers clamps the overlapped points of two lines again, right pliers is again to clamp and be energized two lines carry out solderless wrapped connection.In above-mentioned operation process, often meeting is after two lines are costed, when unclamping left pliers; overlapped points throws off generation electric spark; or right pliers is when doing winding operation, two lines that left pliers is clamped are because being subject to torsion disengagement etc., and the live wire bullet of sometimes throwing off is caused danger to human body or other conductor.In some operations, a hand is sometimes needed to clamp simultaneously or fix the work of two parts, as carried out soldering, electric welding etc. to two parts.Therefore, need a kind of equipment and electrician can be made just with a hand can to carry out clamp to two parts and fix, without the need to frequently changing instrument in operation, effectively reducing in livewire work and producing unexpected possibility.
Summary of the invention
Technical problem underlying to be solved by this invention is to provide a kind of pliers, reaches the object that a hand a pair of tongs clamps two objects simultaneously.
In order to solve above-mentioned technical problem, the invention provides a kind of three leg pliers, comprising the first pincers leg, the second pincers leg and the 3rd pincers leg; Described first pincers leg, second pincers leg and the 3rd pincers leg by can mutually rotationally tip axle fix, described first pincers leg, second pincers leg and the 3rd pincers leg one end forms the first jaw working region and the second jaw working region; The other end of described first pincers leg, the second pincers leg and the 3rd pincers leg is for grasping section.
In a preferred embodiment: described first working region comprises the first jaw of an ellipse and linear second jaw; The shape of described second jaw working region is identical with the first jaw working region or not identical.
In a preferred embodiment: the both sides, one end of described second pincers leg are provided with pincers tooth, and the other end is thumb grip section; Fixing ear with holes is provided with in described thumb grip section.
In a preferred embodiment: one end of described first pincers leg is provided with clamps pincers tooth corresponding to leg side with second, thus forms described first jaw working region with the second pincers tooth clamping leg side; The other end of described first pincers leg is the grasping section of forefinger and middle finger.
In a preferred embodiment: one end of the 3rd pincers leg is provided with clamps pincers tooth corresponding to leg opposite side with second, thus forms described second jaw working region with the second pincers tooth clamping leg opposite side; The other end of described 3rd pincers leg is grasping section that is nameless and little finger, and is flexibly connected with thumb grip section by described fixing ear with holes; 3rd pincers leg pincers increment with grasp section for being flexibly connected.
In a preferred embodiment: described first jaw working region is steel construction; The surface of the second jaw working region is provided with insulating barrier; Described grip sheaths is provided with insulation sleeve.
In a preferred embodiment: the pincers increment of described 3rd pincers leg is flexibly connected by flat mouth with grasping section.
Compared to prior art, technical scheme of the present invention possesses following beneficial effect:
A kind of three leg pliers provided by the invention, are provided with two jaw zones of action, and 3 grip parts, and one hand therefore can be used to clamp down on two objects simultaneously.Avoid traditional electrician frequently to change when hot line job use hand thus unclamp the object clamped down on, cause the potential safety hazards such as electric leakage.Improve the security of hot line job.

Detailed description of the invention
Hereafter the present invention will be further described with detailed description of the invention by reference to the accompanying drawings.
With reference to figure 1, a kind of three leg pliers, comprise the first pincers leg 1, second and clamp leg 2 and the 3rd pincers leg 3; Described first pincers leg 1, second clamp leg 2 and the 3rd pincers leg 3 by can mutually rotationally tip axle 4 fix, described second pincers leg 2 both sides, one end be provided with pincers tooth 21, the other end is thumb grip section 22; Fixing ear 23 with holes is provided with in described thumb grip section.One end of described first pincers leg 1 is provided with clamps pincers tooth 11 corresponding to leg 2 side with second, thus forms the first jaw working region 5 with the second pincers tooth 21 clamping leg side; The other end of described first pincers leg 1 is the grasping section 12 of forefinger and middle finger.One end of 3rd pincers leg 3 is provided with clamps pincers tooth 31 corresponding to leg 2 opposite side with second, thus forms described second jaw working region 6 with the second pincers tooth 21 clamping leg opposite side; The other end of described 3rd pincers leg 3 is grasping section 32 that is nameless and little finger, and is flexibly connected with thumb grip section 22 by described fixing ear 23 with holes; The pincers increment of the 3rd pincers leg 3 is flexibly connected by flat mouth 33 with grasping section.
Electrician is when operating, apply pressure by the grasping section 12 to thumb grip section 22, forefinger and middle finger, grasping section 32 that is nameless and little finger, described first jaw working region 5 and the second jaw working region 6 measuring targets can be controlled and carry out clamp and fix.Therefore only can carrying out clamp to two objects with a hand and a pliers, without the need to changing instrument and operator in operation, doing so avoids when charged testee is unclamped, the electric leakage accident of generation.Improve the security of live line work.
First jaw working region 5 described in the present embodiment comprises the first jaw of an ellipse and linear second jaw; The shape that such design makes it possible to the object of clamp is more various, and bulky object uses the first jaw to carry out clamp, and the object of small volume then uses the second jaw.The shape of described second jaw working region 6 is identical with the first jaw working region.
Described first jaw working region 5 is steel construction, uses in the ordinary course of things; The surface of the second jaw working region is provided with insulating barrier, uses in live line work; Described grip sheaths is provided with insulation sleeve.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
