Реферат: A grass trimmer head (36) has a trimmer head assembly (4) and a metal-rod blade assembly (3). The blade assembly is characterized by a length of solid metal-rod (1), and a spherical portion (2), attached to one end. The head assembly is made of an inverted metal cup (7) with a plurality of spherical cavities or sockets (31), placed equidistantly around the internal vertical wall and penetrating the outside wall, creating a predominantly circular opening (32). The blade assemblies are inserted into the cavities, snapping into place and held loosely by a spring-loaded retainer, for easy removal or replacement The ball joint formed allows the blade assembly to rotate freely in all directions. Each external opening is extended on the trailing side with a cavity (33) allowing the blade assembly to rotate at higher angles in the trailing (11) and upward (15) directions.
