Abstract
The invention relates to an adjustable speed descender, comprising a left speed-adjusting handle, a right speed-adjusting handle and a main support. A handle return spring in the lower middle of the left speed-adjusting handle is fixedly connected with the lower middle of the right speed-adjusting handle. The left speed-adjusting handle and the right speed-adjusting handle are distributed symmetrically on two sides of the main support, and their middles are rotatably connected with the main support through a pin. Speed may be adjusted by holding the handles by hand, thus operating is convenient. Speed adjusting range may be determined according to hand holding force, and stepless speed adjusting may be given. The descender may be fixed safely to any aerial position through a fixing pin. The adjustable speed descender is simple in structure, convenient to carry along, low in manufacturing cost, conducive to popularization and application, and widely applicable to aerial operation, downhill, aerial escape and the like.
