Fluid line system

The invention provides a fluid pipeline system, relates to the technical field of hydraulic pneumatic control, and can realize that a plurality of executing mechanisms can be controlled to complete telescopic actions by only using two pipelines. The fluid pipeline system comprises a first pipeline and a second pipeline, the first reversing unit is used for enabling the fluid inlet end to be switched between the state of being communicated with the first pipeline or the state of being communicated with the second pipeline; the first pipeline comprises a first branch and a second branch, the first branch and the second branch are used for being connected with one ends of different executing mechanisms respectively, and the first flow direction control unit connected into the first pipeline is used for controlling fluid to flow into the first branch and/or the second branch so as to control the corresponding executing mechanisms to act; the second pipeline comprises a third branch and a fourth branch which are u
