After the cutting tool 621 is matched with the cutting peeling inclined block 63 to peel the outer sheath layer 21, the double-steel-belt armor 22 is exposed, then the cutting driving support 6 is driven by the cutting guiding driving rotating shaft 42 to move leftwards to provide driving force for armor anti-cutting strength detection, and then the anti-cutting strength of the double-steel-belt armor 22 is detected by the armor anti-cutting strength detection mechanism, wherein the detection process specifically comprises the following steps: through the cutting drive support 6 left movement process, constantly pressurize pressure regulation pneumatic cylinder 61 for cutting tool 621 cuts double steel band armour body 22, and at the moment cutting off double steel band armour body 22, outwards resume through double steel band armour body 22 because the elastic potential energy of storage when winding the parcel, outwards extrude arc extrusion piece 72, switch on detection switch 73, pressure regulation pneumatic cylinder 61 internal pressure display value can embody double steel band armour body 22's anti cutting ability this moment, and can show the anti cutting ability contrast that the cutting machine detected through current pressure before the winding cladding of double steel band armour body 22, learn double steel band armour body 22 because the winding cladding is at the inside influence of deformation to its anti cutting protection ability of spot inspection cable 2.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
