摘要

Launcher downward element hole shaft and method for launching an element downward in a column tube hole of shaft it is a universal dart launcher (11) which introduces a D.Ardo (25) by the movement of a dart (25) from a first position to a second position.The rocket dart universal (11) has a body of a pitcher (13) which defines a central orifice (19) which has a geometric axis (20) and the upper and lower ends configured to fix a colOne of the tube. A cartridge (15) housed within the body of a pitcher (13) can move perpendicular to the geometric axis (20) from a first position to a second position.A descending element (25) is positioned within the cartridge (15) so that it is in axial alignment with the central hole (19), while in the first position,And is in axial alignment with the central hole (19) while in the second position.An assembly of the actuator (17) is connected to the body of the launcher (13) to move the cartridge (15) from the first position to the second position when actuated.
