1. An oscillator for converting continuous rotational motion into oscillating motion, comprising:
an input shaft configured to continuously rotate about a first central axis, a portion of a length of the input shaft defining an eccentric section, the eccentric section defining a second central axis that is offset from the first central axis;
a connector rotatably coupled around the eccentric section;
an oscillating shaft offset from the input shaft and configured to rotationally oscillate about a third central axis; and
a pin coupled to the oscillating shaft and extending towards the connector in a direction that is perpendicular to the first central axis and the pin coupled such that a central axis of the pin intersects the third central axis,
wherein the connector comprises a sleeve slidably receiving an end of the pin,
wherein continuous rotation of the input shaft about the first central axis causes an eccentric movement of the connector, and the eccentric movement of the connector oscillates the sleeve along the pin and oscillates the pin with respect to the oscillating shaft, thereby oscillating the oscillating shaft about the third central axis,
wherein the first, second, and third central axes extend in a same direction.
