A combined fork arm on a forklift pallet fork is mainly composed of fork fingers, fork arm joints, fork arm sets, fork arm joint lifting devices, fork arm joint push devices, fork boxes, locking devices and a control system. Objects with space below can be carried, and objects with no space below can be carried as well. Each fork arm joint is formed by connecting one fork handle with one to four fork arms. Each fork arm set is composed of the two corresponding fork arm joints. Each fork arm joint is connected with the corresponding lifting device and the corresponding push device which are independent. When box body type bagged goods with no space below are forked, pallet forks are inserted in the fork boxes and are locked by the locking devices. Wedge openings of the fork fingers of one fork arm joint are inserted in the small seam below the goods, pry up and expand the seam, the fork fingers of the other fork arm joint are instantly inserted in the seam which is pried up, and the fork arm joints alternately conduct prying and inserting. After the fork arms are inserted in the seam, the fork arms of the two joints alternately rise to hold the goods, fall, advance and rise till being inserted to the portion below the goods in a penetrating manner. In the unloading process, the fork arms of the two joints alternately rise to hold the goods still, fall and retreat till the goods are placed at a placement point.
