ACTIVATOR FOR BUILDING UP AND RELEASING A SURE POWER

摘要

This invention relates to an activator (1), comprising: a shaft (2) with an internal thread; a force-transmitting element (3), which is displaceable in the shaft (2) between a starting position and an ending position; - an energy storage element (4) such that when the power transfer element (3) moves from its initial position to its end position, energy is stored and when the energy is released the power transfer element (3) is moved from its end position to its initial position; - and a force building element (5), which comprises an engaging element (6), with an external screw thread (16) for engaging the internal screw thread (14) of the shaft (2), such that the engaging element (6) is movable between a start position and end position corresponding to the start position and the end position of the force transmitting element (3) and wherein the engaging element (6) is adjustable in a first position, its external thread (16) in the internal thread (14) of the shaft (2) and a second position, wherein the engaging element (6) is separate from the shaft (2). ; FIG. 3
