Abstract:
A motor-driven hedge clipper comprising a machine housing (12); a main handle (14) provided with an on-off switch comprising a switching button (16), said main handle (14) being supported on said machine housing (12); a hollow auxiliary handle (22) supported on said machine housing and having a U-shaped inner contour; and a single deadman switch operating mechanism for operating a deadman switch (D) to keep the hedge clipper turned on when the on-off switch is turned on and the deadman switch operating mechanism is activated by an operator of the hedge clipper, said single deadman switch operating mechanism comprisingone and only one button element (26) located within said auxiliary handle (22) and formed to extend around and along the U-shaped inner contour of the auxiliary handle, said button element (26) being supported in said auxiliary handle so as to be movable radially relative to said auxiliary handle in all directions by a hand of an operator;spring means (46, 46', 46"",46'"") for urging said button element (26) outward into an initial position when said button element (26) is released by the hand of the operator;a plunger (56) biased by a spring element (57) so as to be urged from an operating position in which the plunger (56) activates the deadman switch (D), so that the hedge clipper is turned on when the on-off switch is turned on, and into a neutral position in which the plunger (56) deactivates the deadman switch (D), so that the hedge clipper is turned off even when the on-off switch is turned on;a pivotally mounted cam disk (52) with a turning lever (52') engaged with one end of said plunger (56); anda cable line (42) arranged within said auxiliary handle and connected at one end to said button element and at another end thereof to said cam disk (52) so that said cable line (42) rotates said cam disk (52) via said turning lever (52') and moves said plunger (56) in a direction against said spring element (57) when said button element (26) is moved in a direction against said spring means (46,46',46"",46'""), whereby said deadman switch is activated.
