[0002] With the increasing and diversified demands for engineering operations, higher requirements are placed on the working range and flexibility of mechanical equipment. The traditional telescopic arm structure may not be able to meet the needs under certain complex working conditions, so the multiple telescopic arm came into being. The existing multiple telescopic arms have some shortcomings. First, there are some problems with the common telescopic arm structure. For example, some telescopic arms with oil cylinder and wire rope structure, the wire rope will become longer after a period of use, which will affect the linear motion trajectory accuracy of the telescopic arm and cause the operation accuracy to decrease. Secondly, in the fully retracted state, the chain telescopic arm may still need to occupy a certain space. For equipment or places with limited installation space, this may be a problem, which limits its application in some compact space environments. The operating range and flexibility of traditional telescopic arms are limited, and it is difficult to meet some tasks that require long-distance and high-precision operations. In order to solve the above problems, we proposed a 2.5-fold transition station automatic telescopic arm. Utility Model Content
