Abstract: The invention is a multi-tiered line trimmer and shredder apparatus using a number of individual pre-molded or pre-cut nail head string lines. Whenever the engine or motor is running, the apparatus rotates the nail head string lines generating cutting power designed to utilize multiple functions, such as trimming grass or weeds, clearing vegetation by shredding or mulching it, or removing snow. The apparatus consists of a base, cylindrical body, nail head string lines, and cover. The base attaches to a drive shaft or directly to an engine or motor. The cylindrical body is hollow, has holes throughout its wall that may be the same or variable sizes. The nail head string lines are inserted into the holes. The cover is used to cover the cylinder body, and to secure the “nail head” portion of the nail head string lines within the cylindrical body while the apparatus is in use.

Abstract: A window curtain driving assembly is revealed. A pulley driving assembly is pivotally connected to a main body. Pulleys disposed on the pulley driving assembly slid in a curtain track. Thereby the window curtain driving assembly rotates along curves of the window track so that it can also be applied to the curved window track. An auxiliary pulley set is mounted and fixed on a top of the main body. The pulley mount is oriented toward a given direction by the second latch bar on one side of the pulley driving assembly being mounted in the auxiliary pulley set. Thus the window curtain driving assembly can also be applied to a straight curtain track for extension or retraction of a curtain.
