Accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model

Fig. 2 is partial structurtes schematic diagram of the present utility model

In figure: (1) fixedly knife plate (2) is revolved shears plate (3) tool axis nail (4) retaining tooth plate (5) pivot pin (6) support spring (7) eccentric support tooth (8) eccentric shaft seat board (9) and connected interior the steel pipe of pivot pin (10) flexible handle (11) (12) connection extension spring (13) Compress Spring (14) and connect piece (15) screw (16) fixed handle (17) locking switch (18) torsion spring (19) cushion block (20) round pin

The specific embodiment:

Below in conjunction with accompanying drawing, the utility model is described in detail below.

The utility model is Portable cable scissors, as shown in Figure 1 and Figure 2, mainly by fixing knife plate (1), revolve shears plate (2), retaining tooth plate (4), eccentric combiner (by bias support tooth (7), eccentric shaft seat board (8), connect pivot pin (9) form), retaining mechanism (being comprised of locking switch (17), torsion spring (18), pivot pin (5)), flexible handle (10), the fixed handles (16) etc. of advancing form.Revolve shears plate (2) and by tool axis, follow closely (3) and be connected with fixing knife plate (1), retaining tooth plate (4) is connected with fixing knife plate (1) by pivot pin (5), retaining tooth plate (4), under the effect of support spring (6), blocks the cylindrical tooth that revolves shears plate (2), and making to revolve shears plate (2) can not clockwise rotate, if press by retaining tooth plate (4), can remove screens, the eccentric combiner that advances is supportted tooth (7), eccentric shaft seat board (8), is connected pivot pin (9) and form by bias, the tooth of eccentric support tooth (7) can fully mesh with the cylindrical tooth that revolves shears plate (2) when work, the multiple tooth while is stressed, promotes feeding to shear, flexible handle (10) is connected with fixing knife plate (1) by being connected pivot pin (9) and eccentric support tooth (7) via the eccentric shaft seat board (8) being fixedly connected with it, interior steel pipe (11) inside of flexible handle (10) is provided with connection extension spring (12) and is connected with the eccentric one end of combiner that advances, and connects extension spring (12) other end and is connected with round pin (20), in the interior steel pipe (11) of described flexible handle (10) and fixed handle (16), be equipped with cushion block (19) and round pin (20), during use, open flexible handle (10), be with the extension spring (12) that is dynamically connected that eccentric shaft seat board (8) is rotated, and then it is meshing with the cylindrical tooth disengaging of revolving shears plate (2) to drive eccentric support tooth (7) to be moved downward to tooth, revolve shears plate (2) because the effect of retaining tooth plate (4) stops original position, closed flexible handle (10), be with equally the extension spring (12) that is dynamically connected, drive the eccentric combiner that advances to rotate backward, and by tooth, mesh to drive and revolve shears plate (2) and rotate counterclockwise, reciprocally swinging flexible handle (10), revolve shears plate (2) and do counterclockwise feed motion, itself and fixedly knife plate (1) gradually close up, thereby cut off cable, one end of eccentric shaft seat board (8) is provided with Compress Spring (13), and one end of Compress Spring (13) props up eccentric shaft seat board (8), and the other end of Compress Spring (13) props up and connects piece (14), connecing piece (14) is connected with fixed handle (16) and passes through screw (15) and be fixed on fixedly knife plate (1) and locate, the one end that connects piece (14) is provided with support spring (6), and the other end of support spring (6) props up retaining tooth plate (4), retaining mechanism is comprised of locking switch (17), torsion spring (18), pivot pin (5), when the flexible handle of holding with a firm grip (10) and fixed handle (16), eccentric shaft seat board (8) rotates, the recess that drives eccentric shaft seat board (8) edge to be provided with rotates together, under the effect of torsion spring (18), flange one end of locking switch (17) outwards flicks from the recess of eccentric shaft seat board (8), makes flexible handle (10) open immediately and can freely swing, while pinning flexible handle (10), first close up flexible handle (10) and fixed handle (16), press again locking switch (17) downwards, the flange of locking switch (17) is blocked in the recess on eccentric shaft seat board (8), now unclamp two handles, flexible handle (10) and fixed handle (16) are lockable.
