The various innovative teachings of the application.
Fig. 1 schematically shows the bolt clipper according to the utility model one embodiment.As shown in figure 1, bolt clipper bag
It is pivotally connected by connecting shaft 24 with the second jaw 30 to include two jaws, the first jaw 20 up and down.First jaw 20 has inlet wire
Mouth 22 is suitable to receive Transformer shielding line 10, and Transformer shielding line 10 extends to shearing table by incoming line 22 to bolt clipper inside
On face 23.Second jaw 30 is lifted around connecting shaft 24, Transformer shielding line 10 is put into incoming line 22, Transformer shielding line
10 go deep into the first jaw 20, are finally statically placed in the first jaw 20 plane relative with the second jaw 30, i.e. shear plane 23.The
Two jaws 30 have a wire cutter 32, and wire cutter 32 has a circular arc knife face towards shear surface 23, by the second jaw
30 push around connecting shaft 24, and second jaw 30 with wire cutter 32 moves closer to the first jaw 20, will be clipped in two jaws
(20,30) the Transformer shielding line 10 in blocks.
Wire cutter 32 is fabricated to the circular arc knife face of shaping, Transformer shielding line 10 can once be sheared into end in the arc-shaped
Mouthful, fracture section is several lower with file polishing；The waste material length that Transformer shielding line 10 is cut falls between 1 to 2 centimetre
Inside bolt clipper, will not splashes, collect, cleaning it is very convenient.In a preferred embodiment, the edge of a knife of wire cutter 32 uses
Converted steel is processed, and hard just has high intensity, high rigidity, ensures that the edge of a knife is hard, wear-resistant.
First one end of jaw 20 away from connecting shaft 24 can also set a first handle 42, and the second jaw 30 is away from even
One end of spindle 24 can also set a second handle 44., can by joystick 40 to control the motion of jaw (20,30)
So that shearing is laborsaving, it is easy to operation.Anti-skidding sleeve pipe can also be arranged on handle 40, anti-skidding sleeve pipe can be by insulating materials system
Into for example, pvc material.Sleeve pipe is added on handle 40 can be easy to user's more safety and comfortable gripping.This
