The invention relates to a dismounting tool, in particular to a lever power-assisted space camera pulling-out mechanism which is used for overcoming the defect that an astronaut cannot conveniently apply force to pull out a to-be-replaced space camera body in an on-orbit mode. The lever power-assisted space camera pulling-out mechanism comprises at least one power-assisted structure group, wherein each power-assisted structure group comprises a pull block and two power-assisted structure units; the short end of the lever, the pull block and the rear end cover of the camera are in sliding connection, so that arc-shaped motion during rotation of the lever is converted into relative linear motion, push-out of the short end of the lever is achieved by pushing the first push block through the rotating second push block, and pull-out of the long end of the lever is achieved by sliding connection of the long end of the lever and the pull block. Large force can be provided by manually pulling the pull block outwards to enable the space camera body to overcome the adsorption force, so that force application pulling-out is facilitated, the movement process is stable, and the phenomenon of movement track separation is not prone to occurring.

    本发明涉及拆卸工具,具体涉及一种杠杆助力式空间相机拔出机构,用于解决宇航员在轨不便施力拔出待更换的空间相机机身的不足之处。该杠杆助力式空间相机拔出机构包括至少一个助力结构组,每个助力结构组包括拉块和两个助力结构单元;本发明通过杠杆短端,以及拉块与相机后端盖滑动连接,使杠杆转动时的弧形运动转变为相对直线运动,其中杠杆短端的推出通过转动的第二推块推动第一推块实现,杠杆长端的拉出通过杠杆长端与拉块的滑动连接实现,通过人工向外拉拉块即可提供较大的力使空间相机机身克服吸附力,从而便于施力拔出,并且运动过程稳定不易发生运动轨迹脱离现象。
