Because only one side of the article a is clamped between the two clamping arms 11, and the horizontal extending direction of the swing legs 22 at two sides of the two clamping arms 11 is perpendicular to the horizontal extending direction of the article a, the article a and the folding support (such as the swing legs 22 of the two movable support seats 2) can form a cross-sectional structure similar to a T shape on a plane (such as a horizontal plane like the ground), so that the article a can be stably placed on the plane, and the article a cannot fall to any side on the plane, thereby having the beneficial effect of preventing the article from falling.

On the other hand, if the foldable support frame is required to be folded for storage or carrying, as shown in fig. 3, a person can move the article a to the outside of the two clamping arms 11, so that there is no article between the two clamping arms 11 (as shown in fig. 1), and then, as shown in fig. 2, the two clamping arms 11 are pivoted between the two supports 21, and the swing legs 22 are pivoted to the sides of the supports 21, so that the foldable support frame is flattened as a whole, which is beneficial for the person to carry, move or store the foldable support frame.

The foldable support frame comprises two movable supporting seats, wherein the two movable supporting seats are arranged on two sides of a telescopic object clamping device, the telescopic object clamping device is pivoted with the two movable supporting seats, and one side, far away from the telescopic object clamping device, of each of the two movable supporting seats extends outwards or is close to one side of the telescopic object clamping device and is folded inwards. Each of the two movable supporting seats can be easily extended into a large-amplitude supporting seat body, the two extended movable supporting seats can extend along a straight line, the extending direction of the straight line is perpendicular to the extending direction of an object clamped by the telescopic object clamp between the two movable supporting seats, the large-amplitude and high-strength supporting effect on the object is favorably realized, and the benefit of preventing the object from toppling over can be effectively provided; moreover, each of the two movable supporting seats can be folded and collected at the side of the telescopic object clamping device through pivoting, the telescopic object clamping device can further reduce the volume (for example, the two clamping arms can be collected between the two supporting columns through pivoting), the whole folding volume can be flattened, and the folding type supporting frame is convenient for people to carry, move or store and the like.
