Wire-driven switch device

The invention belongs to the technical field of mechanical control, and particularly relates to a wire-driven switch device. The device comprises a movable line, the working end of which is fixed on a target object; the fixed seat is used for being fixed on an installation object, the back of the fixed seat is fixedly connected with the fixed end of the movable wire, and the movable wire is in a tensioned state; the rotating wheel is rotationally arranged on one side of the fixed seat on which the movable wire is mounted, and is provided with an arc-shaped winding part on which the movable wire can be wound; and the switch knob is used for driving the rotating wheel to rotate and is mounted at the front part of the rotating wheel. The movable line is fixed between the fixed seat and the target object, when the rotating wheel rotates clockwise, the arc-shaped winding part equivalently abuts against the movable line to rotate, the original line arrangement of the movable line is changed, the length of the movab
