Abstract

A shield module travel enlarging structure includes a front cover and a rear cover formed with opposite windows. The front and rear covers are assembled to form a module main body having an internal operation space. A shield is mounted in the operation space and movable between a position in alignment with the opposite windows and a position misaligned from the opposite windows. A transmission gear is mounted in the internal operation space of the module main body to cooperate with the shield. The transmission gear at least has a large-gear-ratio gear and a small-gear-ratio gear. The large-gear-ratio gear is drivingly engaged with the shield. A push member is drivingly engaged with the small-gear-ratio gear. When the push member is moved, via the transmission gear, the shield is slid by an enlarged travel.
