The concrete structure and the working process of the invention are as follows:
as shown in fig. 1 to 2, the cutting tool of the present invention is hung on a wire rope to be cut. The shears comprises a cylinder barrel 1, a nested piston rod 3 is arranged in the cylinder barrel 1, and when the nested piston rod 3 extends out of the end of the cylinder barrel 1 in a reciprocating mode, two working states of extending out of a clamping support 303 and extending out of a blade 304 are achieved.

Because the two electric explosion devices 4 are installed in the pressure-resistant rear cover 2 and can be kept stable for a long time, the clamping working time and the cutting working time can be controlled, and the electric explosion device is suitable for underwater operation with various durations. In the standby process of the shears, the shears are high in stability and safety and can be suitable for various working conditions.
The above description is intended to be illustrative, and not restrictive, the scope of the invention being indicated by the claims, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
