摘要： A tightening structure of a musical instrument stand includes stationary or immovable member and a movable member. The movable member includes a cylindrical shaft extending outward in an axial direction. One side of the immovable member has a recess. A bottom of the recess forms a semi-circular arc with a radius of curvature corresponding to that of the shaft. When the shaft is inserted into the recess it abuts against the bottom of the recess. The immovable member has a screw hole communicating with the recess. The screw hole is perpendicular to the axial direction of the cylindrical shaft. A fastening bolt is screwed into the screw hole. One end of the first fastening bolt is inserted into the recess and has a flared end portion to press against the shaft, and another end is connected with a handle. By rotating the handle, the flared end portion is drawn against the shaft, thereby rendering the movable member stationary.

摘要： A quick-release cymbal locking device to be mounted to a stand rod includes a first locking member and a second locking member. The first locking member has an upper nut portion and a lower nut portion. A receiving space is defined between the upper and lower nut portions. The upper and lower nut portions each have a first through hole with a diameter greater than that of the stand rod. The first through hole includes a first threaded portion and a first smooth portion. The second locking member has a head portion and a handle portion. The head portion is inserted into the receiving space and has a second through hole with a diameter greater than that of the stand rod. The second through hole includes a second threaded portion and a second smooth portion.
