The concrete structure and the working process of the application are as follows:
as shown in fig. 1-2, the cutter of the present application is hung on a wire rope to be cut. The cutter comprises a cylinder barrel 1, wherein a nested piston rod 3 is arranged in the cylinder barrel 1, and when the nested piston rod 3 extends out of the end part of the cylinder barrel 1 in a reciprocating manner, the cutter has two working states of extending a clamping bracket 303 and extending a blade 304.

When the steel cable to be cut needs to be clamped, the electric explosion device 4 connected with the outer cavity 103 explodes, oil in the outer cavity 103 flows to the pressure-resistant rear cover 2, at the moment, the pressure of the outer cavity 103 is smaller than the pressure of external seawater, the external seawater pushes the first piston rod 301 to move towards one side of the hook 5, the first piston rod 301 drives the clamping support 303 to extend, and the steel cable to be cut is tightly propped against the hook 5. The state of which is shown in fig. 3.
