When the support 62 is required to support, the sliding member 64 can be driven to move by the second driving member 66 to drive the support 62 to extend out, then the support 62 can be driven to rotate by the third driving member 68 until the support 62 is supported on a placing platform such as the ground, and when the support is not required, the support 62 can be driven to rotate by the third driving member 68 to enable the support 62 and the placing platform such as the ground to be separated in time, preferably, the support 62 can be rotated to be flush with the vehicle body 1, then the sliding block can be driven to move back by the second driving member 66 to drive the support 62 to be integrally retracted into the vehicle body 1, so that the support 62 can be unfolded and retracted, and therefore, when the fork frame 2 is used for taking and unloading goods, the forklift can be prevented from overturning. In addition, in order to detect whether the end of the supporting member 62 contacts the ground or the like, a sensor, such as a force sensor, may be added to the connection between the third driving member 68 and the sliding member 64 to detect the contact state, so that the force applied to the third driving member 68 is transmitted to the sliding member 64 through the force sensor. Specifically, for example, during the adjustment of the supporting member 62, if the force sensor is detected to have an increasing force, indicating that the supporting member 62 has contacted the ground, the adjustment may be stopped. Of course, the angle of the support member 62 with respect to the placement platform such as the ground may be detected by other sensors, such as an angle sensor, so that whether the end of the support member 62 contacts the placement platform such as the ground can be determined by the angle detected by the angle sensor. By providing the first rail 69, the slider 64 can move along the first rail 69, so that the movement of the slider 64 can be guided by the first rail 69, and thus the slider 64 can slide according to a predetermined route, so that the support 62 can be unfolded or folded according to the predetermined route, and thus the support 62 can support the forklift when the cargo is detached as required.
