Abstract
A holding stick for soil treatment elements to be actuated by rotation is provided, comprising a handle that is arranged transversely at the upper end of the stick and can be locked into position and rotated in stages relative to the stick. The handle can be adjusted relative to the stick within an axial limit by means of a pivot that is arranged in the center of the handle and engages in the hollow upper end of the stick. Oppositely directed engaging saw tooth-like helical gearings are arranged at the pivot and the stick, enclosing the pivot and the stick like a ring. Said helical gearings form a ratchet, and the treatment element located at the lower end of the stick can be actuated in the rotation direction by means of said ratchet.
