摘要

Improvements in the construction of topographic sights, characterized in that the sight is constituted by a telescopic assembly, in which the successive bodies are in solidarity with each other, when assembling the sight, by devices of annular spring, which acts as a slip; of whose bodies, the end of which has a screwed end, which unscrewed has accommodation at the end of the body, and the other end has a hilt attached, with a sheath of the set collected, complete the presentation and function of a cane.
