[0042] like Figure 3 As shown, the technical solution adopted in this embodiment is: a multi-combination desktop high and low position cantilever bracket, including a base 1, a lower rod 2, an extension rod 3, a middle rod 4, and an upper rod 5;

[0043] The base 1 has a circular hole 1a; one end of the lower rod 2 has a first stepped shaft 6, and the other end of the lower rod 2 has a hollow shaft 7, with a first bushing 8 inside the hollow shaft 7; the extension rod 3 is a hollow shaft, with a second bushing 9 at the upper end and a second stepped shaft 10 that matches the first bushing 8 at the lower end; the middle rod 4 is a stepped shaft that matches the second bushing 9, and a disc 11 is provided at the upper end of the middle rod 4;

[0044] The upper rod 5 has several elongated holes 51 on its side; one end of the upper rod 5 is connected to the disc 11, and a first hand-tight nut 15 is provided between the upper rod 5 and the disc 11, and the upper rod is fixed on the disc 11 by the first hand-tight nut 15.

[0046] The inner diameters of the circular hole 1a, the first bushing 8, and the second bushing 9 are the same.

[0047] The outer diameters of the first stepped shaft 6, the second stepped shaft 10, and the middle rod 4 are the same;

[0048] The second stepped shaft 10 is embedded in the round hole 1a, the first stepped shaft 6 is embedded in the second bushing 9, and the middle rod 4 is embedded in the first bushing 8.

[0049] The lower rod 2 is provided with a first hand screw 13 on its side, and the middle rod 4 is fixed in the first bushing 8 by the first hand screw 13.

[0052] Example 2

[0053] like Figure 4 As shown, the difference between this embodiment and embodiment one is that the lower rod 2 and its corresponding accessories are not used, and the middle rod 4 is directly embedded in the second bushing 9.

[0054] The effect of this embodiment is to reduce the height between the upper rod 5 and the base 1, and to shorten the distance between the rotating part of the upper rod 5 and the base 1, thereby improving the support stability.

[0055] Example 3

[0056] like Figure 5 As shown, the difference between this embodiment and embodiment two is that the extension rod 3 and its corresponding accessories are not used, and the middle rod 4 is directly embedded in the round hole 1a.
