Abstract
A transmission mechanism includes an outer sleeve and an eccentric wheel. The outer sleeve is fixed to a movable block. The eccentric wheel is rotatably installed in the outer sleeve. The eccentric wheel is rotatable relative to the outer sleeve. The eccentric wheel has a mounting hole mountable on a drive shaft. A central axis of the mounting hole is parallel to, and at a predetermined distance from, a central axis of the eccentric wheel, such that the transmission mechanism can convert a rotational motion of the drive shaft into a linear reciprocating motion of the movable block.
