ABSTRACT:
An angle adjusting device for adjusting the relative positions of musical instruments, such as a bass drum and jazz tomtom. The angle adjusting device has two rods for holding the musical instruments separately. Each rod has a head which includes an annular inclined toothed portion. A wing nut mounted on one end of the axle and a lever having a cam surface for abutting against the wall of either one of the heads, through which full engagement, partial engagement and disengagement can be accurately set. Thus, rotation of one head relative to the other to adjust the angle of two rod can be implemented simply by singlehanded actuation of the lever.
