Abstract

A foldable telescoping mechanism comprises a first body (4) and a second body (5). The first body (4) has a first connecting part (2). The second body (5) can rotate relative to the first body (4) andhas a second connecting part (3). The first connecting part (2) and the second connecting part (3) are assembled in a movable manner and have a telescoping state and an extending state. In the telescoping state, the first connecting part (2) and the second connecting part (3) are at least partially superposed, and relative rotation between the first body (4) and the second body (5) is restricted.In the extending state, the first connecting part (2) is far from the second connecting part (3). The second body (5) is rotatable and is folded on the first body (4). The foldable telescoping mechanism can be folded and telescope and can improve strength of a connecting part in an extended use state.

Description

technical field [0001] The invention relates to a folding telescopic mechanism, a propeller protection device and a rotor drone. Background technique [0002] When the UAV is carried, transported, and flew, the propellers on the UAV are extremely vulnerable to damage. Therefore, it is necessary to assemble a paddle protection device on the propeller to play the role of paddle protection. The relevant oar protection cover can be folded, but the structural strength of the connection part is not high when it is unfolded for use, and it is easy to be damaged. Contents of the invention [0003] The invention provides a folding and telescopic mechanism, a propeller protection device and a rotor drone, wherein the folding and telescopic mechanism can be folded and stretched, and can improve the strength of the connection part when unfolded and used. [0004] According to the first aspect of the embodiments of the present invention, there is provided a folding telescopic mechanis...
