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.
