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, more particularly to a kind of pliers.
Background technology
In construction site field power supply sets up and installs, often need to carry out live line connection to mutual unfixed two wires,
The insulation of electrician's generally elder generation's strip off both threads, then costs energization both threads with left and right two pairs of pliers, then vacates left pliers folder
Firmly after the overlapped points of both threads, both threads of the right pliers again to clamping and being powered carry out solderless wrapped connection.In above-mentioned operation process, Chang Hui
After both threads are costed, when left pliers is unclamped, overlapped points are disengaged and produce electric spark, or right pliers is when winding operation is done, left
The both threads that pliers is clamped are because by torsion disengagement etc., the live wire bullet for disengaging sometimes is caused danger to human body or other conductors.
In some operations, it is sometimes desirable to which the work of two parts is clamped or fixed to hands simultaneously, such as two parts are carried out soldering,
Electric welding etc..It is therefore desirable to have a kind of equipment enables to electrician just can carry out clamp and fixation to two parts with a handss,
Without the need for frequently changing instrument in operation, unexpected probability in effectively reducing livewire work, is produced.
The content of the invention
Technical problem underlying to be solved by this invention is to provide a kind of pliers, reaches a handss a pair of tongs while folder
The firmly purpose of two objects.
In order to solve above-mentioned technical problem, the invention provides a kind of three lower limbs pliers, comprising the first pincers lower limb, the second pincers lower limb
With the 3rd pincers lower limb；Quilt can mutually rotationally bearing pin be fixed for the first pincers lower limb, the second pincers lower limb and the 3rd pincers lower limb, first pincers
One end of lower limb, the second pincers lower limb and the 3rd pincers lower limb constitutes the first jaw working region and the second jaw working region；First pincers
The other end of lower limb, the second pincers lower limb and the 3rd pincers lower limb is grasping section.
In a preferred embodiment：The first jaw working region includes the first jaw of an ellipse and linear
Second jaw；The shape of the second jaw working region is identical with the first jaw working region or differs.
In a preferred embodiment：One end both sides of the second pincers lower limb are provided with pincers tooth, and the other end is thumb grip section；Institute
Fixed ear with holes is provided with stating thumb grip section.
In a preferred embodiment：One end of the first pincers lower limb is provided with pincers tooth corresponding with the second pincers lower limb side, so as to
The first jaw working region is constituted with the pincers tooth of the second pincers lower limb side；The other end of the first pincers lower limb is forefinger and middle finger
Grasping section.
In a preferred embodiment：One end of 3rd pincers lower limb is provided with and the second pincers corresponding pincers tooth of lower limb opposite side, so as to
The pincers tooth of the second pincers lower limb opposite side constitutes the second jaw working region；It is described 3rd pincers lower limb the other end for it is nameless with it is little
The grasping section of thumb, and be flexibly connected with thumb grip section by the fixed ear with holes；The pincers increment of the 3rd pincers lower limb and grasping
Section is flexible connection.
In a preferred embodiment：The first jaw working region is steel construction；The surface of the second jaw working region
It is provided with insulating barrier；The grasping section is provided with insulation sleeve.
In a preferred embodiment：The pincers increment of the 3rd pincers lower limb is flexibly connected by flat mouth with section is grasped.
Compared to prior art, technical scheme possesses following beneficial effect：
The three lower limb pliers of one kind that the present invention is provided, is provided with two jaw zones of action, and 3 grip parts, therefore can make
Simultaneously two objects are clamped down on singlehanded.Traditional electrician is avoided frequently to change using handss so as to unclamp pincers in hot line job
The object of system, causes the potential safety hazards such as electric leakage.Improve the safety of hot line job.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
With reference to Fig. 1, a kind of three lower limbs pliers, comprising the first pincers pincers of lower limb 1, second lower limb 2 and the 3rd pincers lower limb 3；The first pincers lower limb
1st, the second pincers lower limb 2 and the 3rd pincers lower limb 3 by can mutually rotationally bearing pin 4 is fixed, one end both sides of the second pincers lower limb 2 are provided with pincers tooth
21, the other end is thumb grip section 22；Fixed ear with holes 23 is provided with the thumb grip section.One end of the first pincers lower limb 1
Pincers tooth 11 corresponding with the second 2 side of pincers lower limb is provided with, so that the first jaw working area is constituted with the pincers tooth 21 of the second pincers lower limb side
Domain 5；The other end of the first pincers lower limb 1 is the grasping section 12 of forefinger and middle finger.One end of 3rd pincers lower limb 3 is provided with and the second pincers lower limb
The corresponding pincers tooth 31 of 2 opposite sides, so as to constitute the second jaw working region 6 with the pincers tooth 21 of the second pincers lower limb opposite side；Institute
