[0024] The circular protrusion 30 is disposed on the first support rod 10 and has a first inclined surface 31 thereon;

[0025] The circular groove 40 is disposed on the second support rod 20 and has a second inclined surface 41 thereon. The second inclined surface 41 can abut against the first inclined surface 31 when the circular protrusion 30 is inserted into the circular groove 40.

[0026] The adjustment assembly 50 is connected between the first support rod 10 and the second support rod 20, and is used to adjust the depth of the circular protrusion 30 inserted into the circular groove 40;

[0027] The sliding assembly 60 is connected between the first support rod 10 and the adjusting assembly 50 or between the second support rod 20 and the adjusting assembly 50 to provide assistance for the relative rotation between the adjusting assembly 50 and the first support rod 10 or the second support rod 20 .

[0028] ① In this utility model, reference is made to Figure 1-2 As the first embodiment of the utility model, the circular protrusion 30 and the first support rod 10 are integrally formed by a plastic material, and the second support rod 20 is also injection molded by a plastic material. It should be noted that the size of the circular protrusion 30 is slightly larger than the size of the circular groove 40, so that when the circular protrusion 30 is inserted into the circular groove 40, the inner wall of the circular groove 40 squeezes the outer wall of the circular protrusion 30, that is, the first inclined surface 31 and the second inclined surface 41 abut against each other, thereby generating friction, and when the bolt 51 is rotated, the first support rod 10 will be driven to move toward the second support rod 20, which makes the depth of the circular protrusion 30 inserted into the circular groove 40 deeper, and the friction between the circular protrusion 30 and the circular groove 40 is also greater, while realizing the function of friction adjustment, the maximum weight of the electrical main body that the support frame can support is also greater, meeting more usage requirements, and because the circular protrusion 30 and the circular groove 40 are both annular structures, the first support rod 10 and the second support rod 20 can rotate relative to each other, realizing the angle adjustment of the support frame.

[0029] ② Since the nut 52 is preferably a hexagonal nut, the hexagonal nut rotates with the second support rod 20, so that the bolt 51 rotates relative to the first support rod 10. By providing a sliding assembly 60 between the head of the bolt 51 and the first support rod 10 to help the relative rotation (sliding) between the bolt 51 and the first support rod 10, the friction between the first support rod 10 and the bolt 51 can be avoided to cause wear of the first support rod 10;

[0030] ③The advantages of the utility model are: through the above structure, the angle between two adjacent support rods can be maintained, and the angle between the two support rods can be changed at any time when subjected to external force, and a smaller force can be applied to the adjustment component to create a larger friction force between the first inclined surface and the second inclined surface, while also avoiding wear between the adjustment component and the support rod.

The second gasket 62 is passed through the bolt 51 and abuts against the other side of the plane bearing 63 and the first support rod 10 or the second support rod 20 respectively.

[0033] As a first embodiment of the connection between the circular protrusion 30 and the first support rod 10 , the circular protrusion 30 and the first support rod 10 are integrally formed of a plastic material.

[0034] As a second embodiment of the connection between the circular protrusion 30 and the first support rod 10, the circular protrusion 30 and the first support rod 10 are integrally formed of metal material, and also include a resistance sleeve 70 sleeved on the circular protrusion 30, and the first inclined surface 31 is formed on the resistance sleeve; in this embodiment, the circular protrusion 30 and the first support rod 10 are integrally formed of metal material, and also include a resistance sleeve 70 sleeved on the circular protrusion 30, and the first inclined surface 60 is formed on the resistance sleeve 70; it should be noted that the size of the circular protrusion 30 after the resistance sleeve 70 is sleeved is slightly larger than the size of the circular groove 40, so that when the circular protrusion 30 is inserted into the circular groove 40, the inner side wall of the circular groove 40 squeezes the outer side wall of the resistance sleeve 70, that is, the first inclined surface 31 It abuts against the second inclined surface 41, thereby generating friction; further, the resistance sleeve 70 can be made of plastic, and when the bolt 31 is rotated, the first support rod 10 will be driven to move toward the second support rod 20, which makes the resistance sleeve 70 and the circular protrusion 30 inserted into the circular groove 40 deeper, and the friction between the resistance sleeve 70 and the circular groove 40 is also greater, while realizing the function of friction adjustment, the maximum weight of the electrical main body that the support frame can support is also greater, meeting more usage requirements, and because the resistance sleeve 70, the circular protrusion 30 and the circular groove 40 are all annular structures, the first support rod 10 and the second support rod 20 can rotate relative to each other, thereby realizing the angle adjustment of the support frame.

[0035] In one embodiment, the resistance sleeve 70 is provided with a through groove 71 which penetrates along its movement direction, and the through groove 71 penetrates the front side, the rear side, the inner side and the outer side; by providing the through groove 71, the deformation effect of the resistance sleeve 70 can be improved, thereby further improving the friction between the resistance sleeve 70 and the circular protrusion 30 and the circular groove 40.
