At this moment, the angle between the third hinge rod 12 and the fourth hinge rod 13 is changed accordingly, so that the cutting angle of the cutting knife 8 is changed, and the situation that the cutting device in the related art can only cut a cable bridge according to a fixed angle, and the cutting angle of the cutting device is difficult to adjust by a worker is effectively reduced.

In addition, because the angle between the bearing plate 6 and the fourth hinge rod 13 changes, the driving rod 24 moves along the length direction of the rack 1, thereby driving the driven rod 25 to move along the length direction of the rack 1, because the first connecting rod 27 is hinged with the second connecting rod 28, along with the movement of the driven rod 25, the angle between the first connecting rod 27 and the second connecting rod 28 gradually increases, at this time, because the lengths of the first connecting rod 27 and the second connecting rod 28 are not changed, one end of the adjusting plate 19, which is far away from the salient point, gradually rises relative to the rack 1, so that the opening of the dust hood 20 always keeps a straight line with the tangential direction of the vertex of the cutting knife 8, thereby effectively realizing synchronous change of the collection angle of the dust hood 20 to the waste scraps when the cutting angle of the cutting knife 8 changes.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
