| 摘要 |
A device to retract cams of spring-loaded camming devices (SLCD) used in rock climbing protection. The device includes a retraction mechanism operable on the SLCD and a control interface to receive input from a climber's hand. A linkage of variable length is disposed between the retraction mechanism and the control interface. The linkage may be adjusted between a longer deployed length for cam retraction and a shorter length to facilitate transportation and storage of the device.
