Abstract
The utility model discloses a descender which solves the problem of inconvenience for use of the traditional 8-shaped ring type, or shackle type or rod type descender. According to the descender provided by the utility model, through arranging a rope pressing member upwards or downwards sliding under the control of hands, the rope pressing member extrudes a wound rope on a spindle when upwards sliding, the friction force of the wound rope is increased, and a human body stops descending; and the wound rope is not pressed when downwards sliding, the friction force of the wound rope is reduced, and the human body descends. The descender has the beneficial effects that a user only needs operating the rope pressing member on the descender in a use process to ensure that the rope pressing member downwards or upwards slides, and the human body can descend or stop descending. The descender has the advantages of simpleness in operation, safety and convenience.
