For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of steel strand wire folding forceps; Comprise two claw beams, two claw beams are hinged in an end place, and hinge is perpendicular to two claw beams; The other end of two claw beams is handle end, is respectively equipped with on two claw beams to be used to the spacing corresponding section that makes steel strand wire of same steel strand wire and to pull line structure with what corresponding claw beam moved.
Said two claw beams are hinged with axle sleeve through the axle that is separately positioned on the corresponding claw beam, and said axle is vertically fixed on the claw beam through its end, and said axle sleeve is fixed on another claw beam through its side face, and said axle rotates inserting in axle sleeve; The termination that said axle passes axle sleeve is provided with disconnecting prevention structure.
Said disconnecting prevention structure is pin.
Also be arranged with C jacket tube on the axle sleeve of said claw beam.
The said line structure of pulling is a hooked shape structure.
Also be provided with thread depressing mechanism on two claw beams, thread depressing mechanism comprises: thread depressing mechanism comprises the Wire crimping cap of corresponding hooked shape structure opening, line ball spring, spring bearer plate, nut, connecting rod, unwrapping wire handle; The line ball spring is packed in hold-down nut, and line ball spring one end is arranged in hold-down nut, and the other end is arranged in the hole of Wire crimping cap; Spring bearer plate is fixed by nut, and nut connects with corresponding claw beam rigidity, and spring bearer plate is provided with pin thread; After screwing in the box of hold-down nut, the pressure of adjustable springs.
The face that said Wire crimping cap contacts with steel strand wire is an arc sphere, to adapt to the not steel strand wire in collinear footpath.
Wire crimping cap, unwrapping wire handle, unwrapping wire handle, Wire crimping cap, connecting rod are that rigidity connects or integral structure, are assemblied on the corresponding claw beam in the end points place activity of connecting rod.
The steel strand wire folding forceps that the utility model provides; Can intersect bending to steel strand wire, so that steel strand wire form better shape " U " bending, convenient electric power backguy and the lightning-arrest wire clamp made; Overcome the problem that line guy is wasted time and energy of making; Improve the fabricating quality and the technology of lightning-arrest wire clamp and anchor clamp, reduced the risk that the backguy bounce-back is hurted sb.'s feelings, had significant good effect.

Embodiment
Below in conjunction with accompanying drawing to the utility model further detailed description.
Comprise two claw beams, two claw beams are hinged in an end place, and hinge is perpendicular to two claw beams, and the other end of two claw beams is handle end, are respectively equipped with on two claw beams to be used to the spacing corresponding section that makes steel strand wire of same steel strand wire and to pull line structure with what corresponding claw beam moved.
Pull line structure and can adopt the crotch structure, the sweep of crotch forms crossed beam trunking, during use, linear steel strand wire is passed two crossed beam trunkings respectively, holds handle then, and rotating claw beam can bend steel strand wire.
As shown in Figure 1 is a kind of with respect to embodiment 1 further improved steel strand wire folding forceps; Comprise: left claw beam 1, right claw beam 2, left hand 7, right handgrip 8, rotating shaft 3, axle sleeve 4; Rotating shaft 3 and axle sleeve 4 are separately fixed at the hinged end head of left and right claw beam, left hand 7, right handgrip 8 is positioned at the non-hinged end of left and right claw beam." U " shape ring was big or small after the size of axle sleeve 4 external diameters can be controlled the steel strand wire bending; The front portion of left and right claw beam (hinged end) is a lath-shaped; The rotating shaft 3 of left side claw beam 1 is inserted in the axle sleeve 4 of right claw beam 2, and axle sleeve 5 certain-lengths are stretched out in rotating shaft 3, in the rotating shaft of stretching out axle sleeve, establish the spring clamping body; Draw-in groove by being located in the rotating shaft is formed with " C " shape spring collar, and " C " shape spring collar snaps in rotating shaft can not be separated with axle sleeve.Perhaps partly get cross through hole stretching out axle sleeve, prevent that with pin rotating shaft from separating with axle sleeve.Pin can also substitute with split pin as a kind of spacing disconnecting prevention structure, and when adopting split pin, it is anti-skidding to increase pad.The corresponding catch (5,6) that is provided with bending on two claw beams, its bending part forms crossed beam trunking, and two crossed beam trunkings are point-blank.The diameter of crossed beam trunking than the curved steel strand wire of tearing open big 0.5～1.5 millimeter.Left and right claw beam can be a lath-shaped in this section of crossed beam trunking to handgrip, also can be the pipe shape.Left hand designs 7 with right handgrip 8 ergonomic.
