The invention relates to a single-point adjustable switching device for a forklift steering axle intensity test. The device comprises a crossbeam assembly; a pressing head connected with a power output head is arranged above the crossbeam assembly; haff units connecting the crossbeam assembly and a steering axle are arranged below the crossbeam assembly; and longitudinal adjusting bolts enabling the lower plane of the crossbeam assembly and the upper plane of the steering axle to be parallel to each other and horizontal adjusting bolts for adjusting horizontal relative positions of the haff units and the pressing head are arranged on the crossbeam assembly. According to the technical scheme, with the longitudinal adjusting bolts, the lower plane of the crossbeam assembly and the upper plane of the forklift steering axle are parallel to each other; and with the horizontal adjusting bolts, the position of the crossbeam assembly is adjusted, thereby realizing the horizontal change of the pressing head and guaranteeing that the revolving central line of the pressing head and the revolving central line of the steering axle are located in a same plumb plane. Therefore, a horizontal unbalance loading phenomenon during the loading process can be avoided; the test requirement can be met; and the force application way is changed from a two-point way to a single-point way, thereby guaranteeing the testing precision effectively.
