ABSTRACT:
A drain plug removing device includes a clip for rotatably engaging and selectively holding a head of a threaded drain plug. The clip has an axis of rotation and includes a pair of openable jaws urged together by a spring. The device includes a selectively bendable, flexible shaft attached to the clip at one end thereof, the shaft being formed of a reboundable coil spring extending away from the clip along the axis of rotation of the clip when the shaft is in an unflexed configuration. The shaft has a handle at another end thereof opposite the clip, such that rotation of the handle applies rotational force to the shaft, which in turn applies rotational force to the clip to cause rotation of the clip and a drain plug held therein. A drain plug can be removed from a crankcase oil pan with the device of the invention without spilling oil onto the fingers and without dropping the plug into a drainage catch basin or funnel beneath the oil pan.
