| 摘要 | A collapsible cutter (10) that utilizes opposing collapsible assemblies having explosive charges (200,300) coupled thereto. The collapsible cutter ( 10) has an linear actuator(100) with a running position and a deployed position. Secured to the actuator (100) is a first plurality of remotely-detonatable charges (200) that are pivotally coupled to the actuator (100) such that the first plurality of remotely-detonatable charges (100) are splayed outward and toward a median of the actuator (100) as the actuator (100) moves from the running position to the deployed position. Also secured to the actuator (100) is a second plurality of remotely-detonatable charges (300) that are pivotally coupled to an opposing end, the second plurality of remotely-detonatable charges (300) are splayed outward and toward the median of the actuator (100) as the actuator (100) moves from the running position to the deployed position. As the actuator (100) continues to move to the deployed position, the first and the second plurality of remotely-detonatable charges (200,300) are placed in a meshed-relation. In this manner, a substantially contiguous cutting profile is defined with the first and the second plurality of charges (200,300). | ||||||
