A first work tool arm is rotatably attached to a frame or reference structure, a second work tool arm rotatably attached to the first work tool arm, and a work tool attached to an end of the second work tool arm. An actuator and a spring are each rotatably attached to the second work tool arm and configured such that separate movement of the first work tool arm relative to the frame or reference structure and movement of the second work tool arm and work tool relative to the first work tool arm are achieved with actuation of the actuator.

A cleaning device includes a bristle bundle and a handle. The handle has a tubular structure and includes a straight part and a bent part, and the bent part is located at the end of the straight part. The bristle bundle is detachably placed in the tubular structure of the handle, and one end of the bristle bundle extends out of the bent part.

A drive chain cleaning and lubricating device including an enclosure assembly, a hose assembly, a brush assembly, and a vehicle assembly is disclosed. These assemblies provide a solution for cleaning and lubricating drive chains. The enclosure assembly includes an opening at opposite distal ends to allow the enclosure body to close around a drive chain. The enclosure assembly includes a hose receiving member located opposite of each other on a top enclosure body and a bottom enclosure body. The hose receiving members can be used to supply lubricant or cleaning solution to the inside of the enclosure as well as provide drainage to the enclosure. The enclosure assembly also includes a brush assembly housed therein. The brush assembly includes a permeable brush mounted to the center of the top and bottom enclosure bodies. The permeable brush allows fluid to flow through the brush as the chain passes through the enclosure.
