A cymbal rod adjusting and locating mechanism includes a fixed casing having a pivot hole and a connector connected to a cymbal stand pole; and a movable casing including first and second clamping members for clamping a cymbal rod therebetween. The first clamping member is provided on a surface adjoining the second clamping member with a confining zone having a screw hole, and the second clamping member is correspondingly provided on a surface adjoining the first clamping member with a clamping zone having a through hole. The first and second clamping members are engaged with each other via a guiding mechanism provided between them, and are elastically pushed apart by first elastic elements provided between them. By extending a pressing bolt through the pivot hole and the through hole to screw into the screw hole, the fixed casing and the first and second clamping members are pressed against one another.
