ABSTRACT:
A recovery force adjusting device for a cymbal stand includes a handle, a driving ring movable relative to the column and having a pin extending through the stop, a supporting seat having a cutout and a wedge the supporting seat, a rotating sleeve rotatably and movably sandwiched between the supporting seat and the driving seat and having a first, a second and a third sets of teeth formed on the rotating sleeve and a recovery spring to move the rotating sleeve upward. Due to the misalignment relationship between the wedge and the tooth of the first set of teeth, sliding movement of the wedge along a slope of the corresponding tooth of the first set of teeth forces the rotating sleeve to rotate and thus the position of the driving ring is changed. A compression force to the spring is thus adjusted.
