[0030] As Figure 2As shown, by lifting the sleeve ring 301 upward, the sleeve ring 301 can drive the upper leg 1 to rise through the top plate 9, the upper leg 1 can drive the lower leg 4 to pull out of the ground through the clamping block one 305 and the clamping groove 5, and due to the gravity, the upper leg 1 and the lower leg 4 are both turned downward, the upper leg 1 and the lower leg 4 keep vertical to the ground, the bottom of the lower leg 4 is placed on the ground, by pressing the sleeve ring 301 downward, the sleeve ring 301 drives the limiting ring 302, the pressing block 303 and the spring 304 to descend, according to the Figure 3 As can be seen, when the limiting ring 302 moves to the bottom end of the upper leg 1, the limiting ring 302 is limited by the upper leg 1, which can prevent the limiting ring 302 from separating from the upper leg 1, and Figure 4 As can be seen, at this time, the pressing block 303 is opposite to the through hole 2, and the lower leg 4 has not been retracted into the upper leg 1, by pressing the pressing block 303 with the hand, the pressing block 303 can extrude the upper end of the clamping block one 305 through the through hole 2, and the sleeve ring 301 is lifted upward at the same time, the sleeve ring 301 drives the pressing block 303 to move upward, the pressing block 303 drives the upper leg 1 to move upward through the through hole 2, and the upper leg 1 drives the lower leg 4 to move away from the ground through the clamping block one 305 and the clamping groove 5, since the top of the clamping block one 305 is extruded, the clamping block one 305 rotates clockwise, the lower end of the clamping block one 305 rotates downward and extrudes the lower leg 4 downward through the clamping groove 5, due to the gravity of the lower leg 4, the lower leg 4 slides downward, and then the clamping block one 305 can move out of the clamping groove 5, at this time, the lower leg 4 can lose the limitation after the clamping groove 5 loses the limitation of the clamping block one 305, by pressing the sleeve ring 301 downward, the sleeve ring 301 can press the upper leg 1 downward through the pressing block 303 and the through hole 2, the upper leg 1 descends, and the lower leg 4 keeps still on the ground, so the upper leg 1 can move to the lower leg 4, and the lower leg 4 can be retracted into the upper leg 1.

[0031] When the pressing block 303 is pressed, the pressing block 303 can extrude the spring 304, the other end of the spring 304 is limited by the sleeve ring 301, so the spring 304 can contract and give the pressing block 303 a reverse thrust, when the pressing block 303 is released, the spring 304 can drive the pressing block 303 to reset, when the pressing block 303 extrudes the upper end of the clamping block one 305 to drive the clamping block one 305 to rotate, since the other end of the torsional spring one 306 is connected with the upper leg 1, the rotation of the clamping block one 305 can drive the torsional spring one 306 to twist, the torsional spring one 306 can give the clamping block one 305 a reverse torsional force, when the clamping block one 305 loses the extrusion, the torsional spring one 306 can drive the clamping block one 305 to reset.

[0032] As shown in the drawings, Figures 1-4As shown, the sleeve ring 301 is provided with a locking assembly 6 for locking the folded support, the locking assembly 6 comprises a push plate 601 and a clamping block two 602, the push plate 601 can push the clamping block two 602, the clamping block two 602 can limit the bottom of the foot plate 7, the push plate 601 is fixedly connected with the pressing block 303 and located above one side of the clamping block two 602, the clamping block two 602 is provided with a torsional spring two 603, the torsional spring two 603 can drive the clamping block two 602 to reset, both ends of the torsional spring two 603 are fixedly connected with the sleeve ring 301 and the clamping block two 602, the lower side of the lower support leg 4 is fixedly provided with the foot plate 7, when the bottom of the lower support leg 4 is inserted into the ground, the foot plate 7 is moved downward to drive the lower support leg 4 to move downward by stepping on the foot plate 7 with the foot, which can conveniently insert the bottom of the lower support leg 4 into the ground to a deeper distance, and is helpful to improve the stability of the support, and the foot plate 7 is movably connected with the clamping block two 602.

[0033] According to the above steps of the lower support leg 4 into the upper support leg 1, when pressing the pressing block 303, the pressing block 303 pushes the push plate 601, according to Figure 4 As shown, the push plate 601 can extrude the upper end of the clamping block two 602, the clamping block two 602 can rotate clockwise around the center axis of the connecting part with the sleeve ring 301, and the bottom of the clamping block two 602 rotates away from the lower support leg 4, since both ends of the torsional spring two 603 are fixedly connected with the sleeve ring 301 and the clamping block two 602, and the clamping block two 602 drives the torsional spring two 603 to twist, the torsional spring two 603 can provide a reverse thrust to the clamping block two 602, when the lower support leg 4 is completely retracted into the upper support leg 1, the top surface of the foot plate 7 extrudes the ground of the upper support leg 1, after the pressing block 303 is loosened, the push plate 601 moves to the left, the clamping block two 602 is reset by the torsional spring two 603, and the bottom of the clamping block two 602 can be clamped at the bottom of the foot plate 7, since the limiting ring 302 is limited from moving downward by the lower side of the upper support leg 1, the limiting ring 302 can drive the sleeve ring 301 to move downward, the sleeve ring 301 drives the clamping block two 602 to move downward, since the bottom of the clamping block two 602 is clamped below the foot plate 7, the clamping block two 602 is limited from moving upward, and the sleeve ring 301, the limiting ring 302 and the clamping block two 602 are limited, so the foot plate 7 can be fixed between the clamping block two 602 and the upper support leg 1, so the foot plate 7 can drive the lower support leg 4 to be fixed in the upper support leg 1, which can prevent the lower support leg 4 from sliding out.

[0034] According to the above-mentioned step of pressing the pressing block 303 with hands, the first clamping block 305 can be away from the clamping groove 5, the second clamping block 602 can be away from the foot plate 7, the foot plate 7 can drive the lower supporting leg 4 to support on the ground by treading the foot plate 7 with feet and pulling the sleeve ring 301 upwards with hands, the sleeve ring 301 can drive the upper supporting leg 1 to move upwards through the pressing block 303 and the through hole 2, the lower supporting leg 4 can be pulled out of the upper supporting leg 1, after the pressing block 303 is loosened, the first clamping block 305 is driven to reset by the torsional spring 306, the first clamping block 305 can be clamped in the clamping groove 5, the first clamping block 305 and the clamping groove 5 can drive the lower supporting leg 4 to be fixed in the upper supporting leg 1, the level of the top plate 9 can be adjusted by pulling the lower supporting leg 4 in each upper supporting leg 1 with hands.

[0035] As shown in Figure 1 and Figure 3 , the side wall of the sleeve ring 301 is fixedly provided with a shoulder strap 8, and the shoulder strap 8 can conveniently be carried by a user.

[0036] As shown in Figures 1-3 , the upper supporting leg 1 is hingedly connected with a top plate 9, the top plate 9 can limit the top of the upper supporting leg 1 and support a supporting plate 10, and one end of the shoulder strap 8, away from the sleeve ring 301, is fixedly connected with the top plate 9.
