The invention discloses a synchronous telescopic four-section telescopic arm built-in drag chain which comprises a fixed basic arm, a moving arm capable of performing telescopic motion relative to the basic arm, a driving piece used for driving the moving arm to perform telescopic motion, a drag chain, a guide pipe synchronously moving with the moving arm and a support. The telescopic end of the driving part is connected with the moving arm, the guide pipe is arranged above the driving part through the support, one end of the drag chain is connected with the basic arm, the other end of the drag chain is connected with the guide pipe, and the guide pipe can drive the drag chain to do telescopic motion above the basic arm. By means of the drag chain with the built-in synchronous telescopic four-section telescopic arm, the operation safety of an arm type overhead working truck can be improved, and a drag chain system can be better protected.
