[0029] In the embodiment, the gas spring refers to a compression gas spring. The application is provided with a first cantilever 20 and a second cantilever 30, both of which can rotate relative to the connecting base 10, and the rotation of the first cantilever 20 and the second cantilever 30 is independent of each other. By rotating the first cantilever 20, the user is allowed to adjust the position of the structure to be installed (such as a display). The balancing assembly includes a first balancing piece 60 and a second balancing piece 70, both of which are connected with the adjusting structure 50. When the adjusting piece 51 moves along the extension direction of the central axis of the adjusting piece 51 relative to the connecting base 10, it can simultaneously drive the first end of the first balancing piece 60 and the second balancing piece 70 to move along the extension direction of the central axis of the adjusting piece 51, while changing the angle of the first balancing piece 60 relative to the first cantilever 20 and the angle of the second balancing piece 70 relative to the second cantilever 30, thereby simultaneously adjusting the spring force value of the first balancing piece 60 and the second balancing piece 70, so that the support device can adapt to structures to be installed of different weights. Compared with the prior art, the support device of the application does not need the user to adjust the force value of each spring respectively, the adjustment process is relatively simple, and the user experience can be significantly improved.

[0030] In addition, the first cantilever 20 and the second cantilever 30 can rotate relative to the connecting base 10, so that the support device can be in a folded state and an unfolded state, Figure 5 In the first state, the support device is in a first extended state, Figure 6 In the second state, the support device is in a second extended state, Figure 7 In the third state, the support device is in a folded state. The support device of the application has the advantages of small structure and high flexibility.

[0031] For reference, Figures 1 to 7 As shown in the figure, in one embodiment of the application, the adjusting structure 50 further includes a rotating piece 52 mounted on the connecting base 10, the rotating piece 52 can rotate around its central axis relative to the connecting base 10, the rotating piece 52 includes a threaded section, and the adjusting piece 51 is threadedly connected with the rotating piece 52 to convert the rotation of the rotating piece 52 into the linear movement of the adjusting piece 51.

[0032] In the embodiment, since the adjusting piece 51 is threadedly connected with the rotating piece 52, by rotating the rotating piece 52 around its central axis relative to the connecting base 10, the adjusting piece 51 can be linearly moved along the extension direction of the central axis of the rotating piece 52 relative to the rotating piece 52, thereby simultaneously driving the first end of the first balancing piece 60 and the second balancing piece 70 to move along the extension direction of the central axis of the rotating piece 52, while changing the angle of the first balancing piece 60 relative to the first cantilever 20 and the angle of the second balancing piece 70 relative to the second cantilever 30, thereby simultaneously adjusting the spring force value of the first balancing piece 60 and the second balancing piece 70.

[0033] It should be noted that when the adjusting member 51 moves to the top position of the rotating member 52 (such as the position in the figure Figure 4 ), the spring force of the supporting device is minimum, and when the adjusting member 51 moves to the bottom position of the rotating member 52 (such as the position in the figure Figure 3 ), the spring force of the supporting device is maximum.

[0034] In an embodiment of the utility model, the central axis of the adjusting member 51 is perpendicular to the central axis of the rotating member 52.

[0035] In the embodiment, the central axis of the adjusting member 51 is perpendicular to the central axis of the rotating member 52, so that when the rotating member 52 rotates around the central axis thereof, the adjusting member 51 can move along the extension direction of the central axis of the rotating member 52, thereby driving the first end of the first balancing member 60 and the second balancing member 70 to move along the extension direction of the central axis of the adjusting member 51.

[0036] The adjusting member 51 is in a cylindrical structure, both ends of the cylindrical structure are provided with an opening, the first end of the first balancing member 60 is arranged in one of the openings and rotationally connected with the adjusting member 51, and the first end of the second balancing member 70 is arranged in the other opening and rotationally connected with the adjusting member 51. Since the adjusting member 51 is in a regular structure, the central axis of the adjusting member 51 refers to the center line in the length direction of the adjusting member 51.

[0037] It should be noted that the central axis of the adjusting member 51 is not absolutely perpendicular to the central axis of the rotating member 52, but is approximately perpendicular in a broad sense.

[0042] In the embodiment, the stop cooperation between the stop portion 522 and the anti-drop piece 53 ensures that the rotating part 52 cannot be detached from the connecting seat 10. At least part of the through department 521 is through the through hole 531 on the anti-drop piece 53 and can rotate relative to the through hole 531. During assembly, the through department 521 only needs to be inserted into the through hole 531, which simplifies the assembly process and facilitates disassembly and maintenance.

[0043] In one embodiment of the utility model, the stop portion 522 is a stop step surface or a stop ring arranged on the outer periphery of the through department 521.

[0044] In the embodiment, if the stop portion 522 is a stop step surface, the stop step surface can form direct surface contact limiting with the anti-drop piece 53. Such surface contact provides a larger contact area, which is beneficial to disperse force and reduce local stress concentration, thereby reducing component wear and prolonging the service life of the equipment.

[0045] If the stop portion 522 is a stop ring arranged on the outer periphery of the through department 521, it can provide a uniform limiting effect in the circumferential direction, and the contact with the anti-drop piece 53 is more balanced. In addition, the stop ring is relatively simple to process, easy to ensure manufacturing precision, and reduces production cost.

[0046] In one embodiment of the utility model, the connecting seat 10 is provided with a threaded hole, and the anti-drop piece 53 is installed in the threaded hole and threadedly connected with the threaded hole.
