The bell-crank lever (18) adjusts the length of the lever arm. It is brought into direct form-fit contact by its free lever arm (19) with the adjustment member (21) on the adjusting spindle (20). The adjustment member interacting with the bell-crank is longitudinally adjustable. The adjustment mechanism uses the adjusting spindle incorporated in the handle and located in a threaded bush (24). |
