    • A fixture for supporting a musical instrument drum, or the like, includes a stem which supports a ball and the ball is clampable between two clamping parts forming a socket for clamping the ball. A pivotable cam draws the two socket parts together or releases them from clamping and unclamping the ball, and the clamp can be oriented at any orientation around the ball. A holding rod for the drum is clamped in a socket between the second of the clamping parts and a third clamping part which is bolted to the second clamping part for clamping the two parts together. Compression springs urge the first and second clamping parts apart and the second and third clamping parts apart respectively against the urging of the cam and of the bolts for tightening the clamping parts together.
    • 用于支撑乐器鼓等的夹具包括支撑球的杆,并且球可夹在形成用于夹紧球的插座的两个夹紧部之间。 可枢转凸轮将两个插座部分拉在一起,或者将它们从夹紧和松开球释放,并且夹具可以围绕球定向。 用于滚筒的保持杆被夹紧在第二夹紧部件之间的插座中,以及第三夹紧部件,其被螺栓连接到第二夹紧部件,以将两个部件夹紧在一起。 压缩弹簧迫使第一和第二夹紧部件分开,并且第二和第三夹紧部件分别抵靠凸轮和用于将夹紧部分紧固在一起的螺栓的推动分开。
