Abstract: An adjusting assembly for a drum support includes multiple adjusting holes defined through the second extension of the secondary base and multiple fixing holes defined in the first extension of the primary base. One adjusting hole corresponds to and aligns with at least two fixing holes such that relative position of the second extension to the first extension is easily adjusted and secured via fixing bolts. An urging plate received in the seat and pushed by distal free ends of two threaded bolts is able to secure the hook inside the seat to provide a supporting force to the drum.

Abstract: A snare-adjusting device is mounted on a snare drum for adjusting tension of a snare and has a base, adjustment assembly and snare mount. The adjustment assembly is mounted through the base and has a barrel, shaft, slider, adjustment head and friction ring. The barrel has two ends. The shaft is mounted rotatably through the barrel. The slider is mounted slidably in and engages one end of the barrel and is mounted on the shaft using threads. The adjustment head is mounted securely on the shaft. The friction ring is mounted slidably through an other end of the barrel, is pressed by a resilient device to abut the adjustment head and provide friction against rotation of the adjustment head. The snare mount is attached to the slider and connects to the snare. The friction holds the adjustment head securely to maintain a steady timbre.

Abstract: A snare drum strainer includes a switch stand, a brake part, a suspender steady base and a pull handle driven part. The brake part can slide inside the switch stand and also can move upward and downward. The suspender steady base is steady located at a lower end of the brake part for clipping multiple snares. The pull handle driven part is pivotally coupled to the switch stand for controlling the brake part to be ascending and descending. The brake part makes use of a self-lubricating bearing and a shaft sleeve to generate a self-lubricating effect. Further, the pull handle driven part makes use of a bolt and a spacer to have the pull handle, the driven buttons and the driven pole pivotal coupled together. When the suspender steady base is in use, friction can be reduced, so as to enhance the fluid movement and further reduce the noise.
