ABSTRACT:
A hand-operated portable tool to detonate blasting charges on a workpiece, including a tool body; a front unit, supported by the body and accommodating an explosive cartridge, for engagement with the workpiece; and a rear unit, supported by the body, including an igniting mechanism for the cartridge. The front unit is movable into a retracted position, with the rear unit being releasable only in the retracted position of the front unit. The tool body includes a first handle to release the igniting mechanism, a security mechanism to render the igniting mechanism inoperative, and a second handle and trigger to render the security mechanism temporarily inoperative, thereby rendering operative the igniting mechanism.
