The invention relates to the technical field of on-orbit maintenance of spacecrafts, in particular to a foot limiter extravehicular transfer device for on-orbit maintenance, which comprises an extension rod and a clamping mechanism, the extension rod is used for extending the transmission distance. The clamping mechanism is used for clamping a handle of the foot limiter. The clamping mechanism comprises a clamping base, two clamping jaws, a sliding shaft, a first locking part and a second locking part. The clamping seat is fixedly mounted at one end of the extension rod; the two clamping jaws can be installed at the end, away from the extension rod, of the clamping base in a face-to-face rotation or back-to-back rotation mode. The sliding shaft can be installed in the clamping base in a sliding mode in the axial direction of the clamping base, and the end, away from the extension rod, of the sliding shaft is hinged to each clamping jaw. The first locking part is mounted on the clamping seat and can act to limit the sliding shaft to slide towards the clamping jaw along the axial direction of the clamping seat or release the limitation on the sliding shaft; the second locking part is installed at the end, close to the clamping base, of the extension rod and can act to limit action of the first locking part or release limitation on the first locking part.

    本发明涉及航天器在轨维修技术领域,尤其涉及一种在轨维修用脚限位器舱外转移装置,包括延长杆和夹持机构;延长杆用于延长传递距离。夹持机构用于夹持脚限位器的把手。夹持机构包括夹座、两个夹爪、滑动轴、第一锁止部和第二锁止部。夹座固定安装于延长杆的一端;两个夹爪可相向转动或背向转动地安装于夹座远离延长杆的一端;滑动轴可沿着夹座轴向滑动地安装于夹座内,远离延长杆的一端分别与每个夹爪铰接;第一锁止部安装于夹座上,能够发生动作,以限制滑动轴沿着夹座的轴向朝向夹爪滑动或解除对滑动轴的限制;第二锁止部安装于延长杆靠近夹座的一端,能够发生动作,以限制第一锁止部发生动作或解除对第一锁止部的限制。
