Modularized two-way linear shaped charge cutter

The invention provides a modularized two-way linear shaped charge cutter. The modularized two-way linear shaped charge cutter comprises at least one modularized cumulative cutter, charge positioning devices, detonation point positioning devices and cumulative direction determination devices. All the modularized cumulative cutters are of the same structure and are connected end to end in series. The corresponding detonation point positioning device is installed at the front end of the modularized cumulative cutter located on the head portion. The corresponding detonation positioning device is also installed at the rear end of the modularized cumulative cutter located on the tail portion. Meanwhile, the cumulative direction determination devices are also arranged at the rear end of the modularized cumulative cutter located on the tail portion. Each modularized cumulative cutter is sleeved with the corresponding charge positioning device, or the separated modularized cumulative cutters are sleeved with the charge positioning directions. According to the modularized two-way linear shaped charge cutter, modularized charge is adopted, the charge length can be determined according to requirements through any combination, the linear charge density is reasonable, charge positioning, detonation point positioning and cumulative cutting direction determining are accurate, and the modularized two-way linear shaped charge cutter can be applied to and popularized in most presplitting blasting and smooth surface blasting engineering.
