AI Technical Summary
Conventional tools are large in size, making them difficult to operate flexibly in the small and complex space of a satellite. They are also prone to being bumped and damaged, and cannot effectively install and tighten fasteners.
Design a telescopic tool, including a tool body, a movable telescopic cylinder, a fixed telescopic cylinder, a tool head, a set screw, and a positioning chuck. The tool's telescopic extension and anti-dislodgement are achieved through a limiting step and an anti-dislodgement limiting structure, making it suitable for operation in confined spaces.
It enables the tool to rotate and fold flexibly in confined spaces, has an adjustable telescopic range, can effectively install and tighten fasteners, and can withstand high torque loads.
