The invention discloses a forklift limiting rod. The forklift limiting rod comprises an outer frame, supporting rods and fixing devices; a hydraulic pump is arranged in the middle of the lower surfaceof the upper end of the outer frame; forks are fixedly arranged on the surfaces of telescopic rods; two annular blocks are arranged on the back side of each fork; fixing frames corresponding to square holes are arranged on the inner walls of the left side and the right side of the outer frame; the fixing devices are inlaid in the surfaces of the fixing frames; thickening areas are arranged on theleft sides and the right sides of the supporting rods; sliding grooves are formed in the upper ends and the lower ends of the thickening areas; and threaded areas are arranged on the two sides of annular protruding blocks. The forklift limiting rod is arranged on the outer frame, in order to prevent the phenomenon that a whole device is deformed due to overlarge stress when a user uses the folksto convey goods, the thickening areas are arranged at the joints of the whole supporting rods and the forks, so that the whole device is reinforced from the overall strength, deformation can be avoided, and in order to solve the problem that dismounting is difficult due to the fact that screw slippage occurs at the joints between the supporting rods and screws when the supporting rods are presseddownwards under the stress, the fixing devices are designed to replace the screws for connection.
