[0039] Support rod 1;

[0040] Hinge 2, fixedly connected to the bottom of the support rod 1, and the bottom and inner side of the hinge 2 are provided with notches;

[0041] First support leg 3, the first end of the first support leg 3 is rotationally connected to the notch of the hinge 2;

[0042] Second support leg 4, slidably connected to the second end of the first support leg 3, and the extending direction of the second support leg 4 is parallel to the extending direction of the first support leg 3.

[0043] In the embodiment of this application, the first support leg 3 is set to be rotatable to be foldable, and the second support leg 4 is set to be slidable to be telescopic, so that the height of the bottom support legs can be freely adjusted during use. During transportation, the support legs can be retracted and folded, thus saving a large amount of space during transportation and improving the transportation volume.

[0044] In this embodiment, the hinge 2 is U-shaped, the opening of the U-shaped hinge 2 faces the center of the support rod 1, and the lower opening of the hinge 2. Since it contacts the support rod 1 above, the opening can be opened or not. The first support leg 3 rotates in the opening of the hinge 2 and includes at least two states, that is, the unfolded state in which the first support leg 3 extends downward from the hinge 2 and the folded state in which it extends toward the center of the support rod 1. When taken out for use, the first support leg 3 is rotated to be unfolded, and the folded state is applicable during transportation.

[0045] A second support leg 4 is slidably connected inside the first support leg 3. In one embodiment, the first support leg 3 has a cavity, the first support leg 3 is sleeved around the periphery of the second support leg 4, and the second support leg 4 changes the overall height of the bottom support leg by changing the length embedded in the first support leg 3. In another embodiment, the second support leg 4 is attached to the side surface of the first support leg 3, and the second support leg 4 changes the overall height of the bottom support leg by changing the length that coincides with the first support leg 3.

[0046] As Figure 2 , Figure 3 and Figure 4 shown, Figure 2 FIG. is a schematic structural diagram of a support rod 1 provided by an embodiment of the present application; Figure 3 FIG. is a schematic structural diagram of a first support leg 3 provided by an embodiment of the present application; Figure 4 FIG. is a schematic structural diagram of a second bolt 18 provided by an embodiment of the present application.

The first support leg 3 has a plurality of through first slots 5, and the second support leg 4 has a plurality of through second slots 6. The extension arm passes through the first slot 5 and the second slot 6.

[0048] In this embodiment, after the overall height of the bottom support leg is adjusted, specifically, after the second support leg 4 and the first support leg 3 are slidably adjusted, the fixed insertion rod 7 is used to lock the relative positions of the first support leg 3 and the second support leg 4, that is, to lock the overall height of the bottom support leg.

[0049] In some embodiments of the present application, a second bolt 18 is further included. The fixed insertion rod 7 is U-shaped and includes two extension arms. Each extension arm passes through the first slot 5 and the second slot 6 and has a threaded hole. The second bolt 18 is threadedly connected to the two extension arms.

[0050] In some embodiments of the present application, the cross-sectional profile of the first slot 5 is the same as the cross-sectional profile of the second slot 6.

[0051] In this embodiment, the cross-sectional profiles of the first slot 5 and the second slot 6 are both rectangular and have equal areas. The spacing between the plurality of first slots 5 and the spacing between the plurality of second slots 6 correspond to the spacing between the two extension arms, so that the two extension arms can be respectively inserted into two different first slots 5 and also pass through two different second slots 6.

[0052] When the height of the support leg is insufficient, first remove the fixed insertion rod 7, then pull out the second support leg 4 until it reaches the appropriate height, and then insert the fixed insertion rod 7 into the first slot 5 and the second slot 6 in sequence, thus fixing the second support leg 4 to the first support leg 3.

[0053] Such as Figure 5 , Figure 6 and Figure 7 shown, Figure 5 is a schematic structural diagram of a guard plate 9 provided by an embodiment of the present application; Figure 6 is a schematic structural diagram of an extension plate 15 provided by an embodiment of the present application; Figure 7 is a schematic structural diagram of a first bolt 16 provided by an embodiment of the present application.
