The invention discloses a combined fork arm of a telescopic arm forklift. The combined fork arm is mainly composed of fork arm couplings, two fork arm sets, fork arm coupling lifting devices, fork arm coupling advancing devices, a pallet fork hanging block and a control system, wherein the two pallet forks of the telescopic arm forklift are replaced with the two fork arm sets, which are used for forking and transporting box body type and bag type objects with no space below for pallet forks to insert; each fork arm coupling is composed by connecting one fork handle with one to four fork arms; each fork arm set is composed of two fork arm couplings; each fork arm coupling is provided with an independent set of lifting device and advancing device; when to fork goods, the fork arm front end wedge of one fork arm coupling is inserted into a small gap underneath the goods firstly and pries upwards to enlarge the gap; the fork arm of the other fork arm coupling is immediately inserted into the pried and enlarged gap, and the prying and inserting processes are alternately carried out; the two fork arms are lifted alternately to hold the goods to stay still, descend, advance and ascend till the fork arms penetrate through the underneath of the goods; when to unload the goods, above the placing point of the goods, the two fork arms alternately hold the goods to stay still, descend and retreat till the goods are placed on the placing point.
