Opposite sides of the first blade 201 and the second blade 202 are provided with mutually matched concave cutting edges for positioning the power cable when the power cable is cut. Meanwhile, when the first blade 201 is driven by the hydraulic device 213 to move and cut, the sunken cutting edge on the first blade 201 extrudes the electric power cable to the direction of the second blade 202, because the outer cladding of the electric power cable is a plastic product, the electric power cable has certain elasticity, when being pressed, the outer cladding of the electric power cable can firstly deform, at the moment, because of the existence of the sunken cutting edge, the outer cladding can deform in the sunken cutting edge, the cross-sectional area of the electric power cable is gradually extruded and reduced, in the linear motion process of the first blade 201, the electric power cable is gradually compressed and cut, and the outer cladding can only deform in the sunken cutting edge, finally, the cutting of the electric power cable is realized, and the cut is flat, compared with the traditional cross cutting mode, the cut is more flat.

And the first blade 201 and the second blade 202 are arranged obliquely relatively, as shown in fig. 3, the extension line of the first blade 201 in the cutting direction intersects with the extension line of the second blade in the cutting direction, and during the movement of the first blade 201, the cutting edge of the first blade 201 contacts with the inner edge of the recessed cutting edge of the second blade 202, so that when the first blade 201 moves, the end point of the movement reaches the inner edge of the recessed cutting edge of the second blade 202, the first blade 201 and the second blade 202 do not collide with each other, and when the first blade 201 and the second blade 202 just intersect, the power cable is cut off, the blade of the conventional cutting device continues to move after the cutting is finished, so that the cut power cable bends under the friction of the blade, and further the cut is uneven, while the cutting device provided by this embodiment can effectively avoid the problem due to the controllable relative positions of the first blade and the second blade 202 and cooperates with the recessed cutting edge .

In addition, a handle 215 is connected to the side of the hydraulic device 213 remote from the first slider 241, and the handle 215 is also covered with a rubber sleeve, i.e., a second rubber sleeve 206. It should be noted that the rubber sleeves of the control portion 203 of the hydraulic device 213 and the handle 215 may be made of other materials with good hand feeling.

The anti-slip patterns may be respectively disposed on a side of the first elastic pad 243 near the knife edge 239 and a side of the second elastic pad 246 near the knife edge 239.

Because the elastic pad has elasticity and the surface of the elastic pad is provided with the anti-slip lines, the contact area between the elastic pad and the power cable can be enlarged, the friction force is improved, and the shake of the power cable in the cutting process is reduced.

In summary, the working principle of the power cable cutting device is as follows: when the device is used by a user, firstly, a power cable to be cut off passes through the knife edge 239 and is aligned, then the locking device 242 is opened to drive the first slider 241 to slide, the top of the first slider 241 is connected with the fixing plate 233 through the sliding device 25, so that the effect that the first slider 241 slides together with the first elastic pad 243 is achieved, the second slider 245, the second elastic pad 246 and the tong head 231 are fixed, the first slider 241 is fixed on the surface of the tong head 231 through the locking device 242 to fix the power cable, and then the hydraulic device 213 pushes the first knife blade 201 to slide to cut off the power cable.

Therefore, the electric power cable shearing device can better cut off the electric power cable, can limit the electric power cable, and avoids the electric power cable from shaking in the cutting and other processing processes.
