A mechanical multiple torque damping device includes a support module, a spindle coupling sleeve and a damping cylinder. The support module includes a mounting seat, a tubular support axle extending from the mounting seat, a friction ring sleeved on the support axle, and a screw shaft extending through the support axle. The spindle coupling sleeve is rotatably sleeved on the support axle to support a horizontal spindle. The damping cylinder is axially displaceable along the screw shaft relative to the friction ring during rotation with the horizontal spindle. A cylinder body of the cylinder has inner frictional surface sections in frictional contact with the friction ring to generate multiple frictional torques to the horizontal spindle.
