Perforator for lawn aerator and lawn aerator having same

Abstract

Disclosed are a perforator and a lawn aerator. The perforator includes a main portion and a plurality of perforating portions. The main portion is in a disk shape, and the perforating portions are integrally formed with the main portion. The perforating portions extend radially outward from an outer periphery of the main portion, and are arranged at intervals in a circumferential direction of the main portion. Each perforating portion forms a cutting portion at a distal end thereof. Between cutting portions of any two adjacent perforating portions, an edge of the perforator is turned over towards one side of the perforator to form a turned-over portion. According to this configuration, a greater bending strength can be obtained. In addition, the connecting portion of the perforating portion and the main portion can be strengthened. Therefore, the manufacturing processes are reduced, and so the manufacturing cost and manufacturing difficulty.
