Manual gardening tool for forming e.g. deherbor, has assembly connected to transverse bar by mechanical connection that prohibits transformation of rotary movement of bar to rotary movement of assembly in trigonometrical rotation direction

摘要

The tool has an assembly (26) formed by helical teeth (4), support (3) and vertical handle (2) connected to a transverse bar (1) relative to an upper end of the handle by a mechanical connection (7) to a shaft. The connection authorizes transformation of rotative movement of the bar into a rotary movement of the assembly in trigonometrical anti-rotation direction of the bar along a vertical axis (9) and prohibits the transformation of the rotary movement of the bar into the rotary movement of the assembly in the trigonometrical rotation direction of the bar.
