Gear device for coupling drive shaft for pivoting around rotational axis, has driving seat formed and arranged in mounting frame and is plugged around drive shaft, such that driving seat rotates together with drive shaft

摘要

The gear device has a driving seat (40) formed and arranged in a mounting frame (30) and is plugged around a drive shaft (21), such that the driving seat rotates together with the drive shaft. Multiple equally angularly spaced guide bars (54) extend upwards from the upper side surface (551). A position limiting unit (90) movably attached on the upper side surface of a gear wheel assembly (50) and is spaced from an abutting unit (32) of the mounting frame.
