Abstract: A locking mechanism comprises a main body, an ejector rod, a guide rod assembly, a carrier plate and a fixing assembly. The carrier plate comprises a center hole and a plurality of annular strip holes. The fixing assembly comprises a rotary disc. The center hole and the annular strip holes can lock the rotary disc in different rotation angles. The guide rod assembly limits the rotation tolerance of the carrier plate, and makes the carrier plate move up and down in the vertical direction. The rotary disc with limited rotational freedom is fixedly connected with the ejector rod, so that the locking mechanism can not only realize the linear lifting motion of the ejector rod, but also reduce the rotation angle error between the carrier plate and the ejector rod. A rotating lifting platform is also provided.

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.
