[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] In the description of the present invention, reference terms such as "one embodiment", "some embodiments", "illustrative embodiment", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present invention.

[0029] refer to Figure 1 and Figure 2 According to the cantilever bracket of the first embodiment of the utility model, the cantilever bracket comprises a rotating upper arm 101, a rotating lower arm 102, a first rotating shaft 201, a first pressing member 211, and a first damper. The rotating upper arm 101 and the rotating lower arm 102 are rotatably connected through the first rotating shaft 201; the first pressing member 211 is connected to one end of the first rotating shaft 201; the first pressing member 211 presses the first damper between the rotating upper arm 101 and the first pressing member 211, and the first damper comprises a first gasket 209 and at least one serrated gasket 208, the serrated gasket 208 and the first gasket 209 are stacked, the serrations of the serrated gasket 208 are in contact with the first gasket 209, and the friction between the serrated gasket 208 and the first gasket 209 can keep the angle between the rotating upper arm 101 and the rotating lower arm 102 fixed.

[0030] In this way, the rotating upper arm 101 and the rotating lower arm 102 are rotatably connected through the first rotating shaft 201, and the first clamping piece 211 is connected to one end of the first rotating shaft 201, and the first damper is pressed between the rotating upper arm 101 and the first clamping piece 211. The first damper includes a first gasket 209 and a serrated gasket 208. The serrations of the serrated gasket 208 are in contact with the first gasket 209. The friction force generated on the contact surface after being clamped by the clamping piece keeps the angle between the rotating upper arm 101 and the rotating lower arm 102 fixed, so there is no need to use a hand-tightened knob to adjust the angle of the cantilever bracket. The rotating arm can be directly rotated to the required angle. The operation is simple and convenient, and the knob-free structure makes the appearance simple and beautiful, thereby improving the appearance quality of the product.

[0031] It should be noted that when the user grasps the rotating upper arm 101 or the rotating lower arm 102 and rotates it, the external force applied by the user can overcome the friction resistance of the first damper, thereby being able to adjust the angle between the rotating upper arm 101 and the rotating lower arm 102. The torque generated by the friction force provided by the first damper is mainly used to offset the torque generated by the gravity of the rotating upper arm 101 and the rotating lower arm 102.

[0032] It should be noted that, in some embodiments of the present invention, the connection between the first pressing member 211 and the first rotating shaft 201 may be a threaded connection. For example, the first pressing member 211 is configured as a nut, and the first rotating shaft 201 is configured as a bolt. The threaded connection is reliable, easy to assemble and disassemble, and has good self-locking performance.

[0033] It should be noted that, in some embodiments of the present invention, the first gasket 209 uses a wear-resistant gasket, which has a large friction force and can better generate friction with the serrated gasket 208. During repeated friction, the wear-resistant gasket has a longer service life than ordinary gaskets. In some embodiments of the present invention, the wear-resistant gasket uses a rubber gasket, and plastic gaskets, graphite gaskets and other materials may also be used.

Placing a single ear in a double-ear structure can increase the contact area and friction area between the rotating upper arm 101 and the rotating lower arm 102, making the connection between the two more stable. The symmetrical design can also enable the first connecting ear 203 and the second connecting ear 205 to simultaneously abut against the third connecting ear 204 when it is subjected to an external force in the axial direction of the first rotating shaft 201, so that the force is more evenly distributed.
