Fixing element for locking a hinged hand crank on the input shaft of a support winch for a semi-trailer

摘要

The invention relates to a fixing element for locking a hinged hand crank on the input shaft of a support winch for semi-trailers, wherein the hand crank is fastened to the input shaft in an articulated manner and can pivot between at least one folded-in rest position and at least one folded-out usage position. According to the invention, said fixing element has a fastening section for fastening to the hand crank and a spring bar connected to the fastening section on which at least one locking section is formed, wherein the locking section reaches over the end face of the input shaft in a form-fitting manner in a folded-out usage position of the hand crank and is simultaneously pulled against said end face of the input shaft.
