The position / surface where the matching groove 120 is connected to the second assembly groove 120 is arc-shaped. The rotating component 3 can be rotatably connected to the first assembly groove 220 by upper and lower rivet connection, or can be rotatably connected by an arc groove with a track. At this time, the rotating shaft 43 can be the edge of the first assembly groove 110 or a certain annular clamping edge. The elastic damping component 2 can be fixed to the fixing plate at the lower end by upper and lower rivets. The elastic damping component 2 can also be clamped at the edge of the second assembly groove 120 by direct clamping. Preferably, the elastic damping component 2 is not rotatable, and one end thereof is preferably shaped as a long groove.

[0032] refer to Figure 4-Figure 6Embodiment 1: The elastic damping component 2 includes a damping mounting seat 21, a damping groove 22, and a magnetic suspension ball assembly 23. The inner side of the damping mounting seat 21 is recessed to form a damping groove 22, wherein the magnetic suspension ball assembly 23 is embedded in the damping groove 22 and its output end faces the ball groove 301, and the magnetic suspension ball assembly 23 includes a first magnetic member 231 located on the inner side and a second magnetic member 232 located on the outer side, wherein the connection position of the first magnetic member 231 and the second magnetic member 232 has a corresponding With respect to magnetism, a ball 233 is provided at the end of the second magnetic member 232. Here, the principle of like charges repelling each other is adopted in magnets. The first magnetic member 231 is located at the bottom of the damping groove 22, and the second magnetic member 232 is located on the outside of the damping groove 22. The second magnetic member 232 is squeezed by the ball 233, and the ball 233 is squeezed by the rotation of the ball groove 301. At the same time, due to the principle of the two magnetic members moving in opposite directions, an elastic buffering effect is formed. Since the magnetic force is not easy to disappear, the service life is longer.

[0033] refer to Figure 4-Figure 6 Specifically, in order to limit the forward and backward rolling of the ball 233 and enable it to roll with the ball groove 301 in a 360-degree rotation posture, in this embodiment, the outer end of the second magnetic member 232 is provided with a rolling groove 212 for the ball 233 to rotate and embed. The rolling groove 212 is a concave structure, which can just support a part of the spherical surface of the ball 233 so that it will not swing left and right. It can only rotate 360 ​​degrees around the center of the ball, or perform telescopic movement as the second magnetic member 232 is acted upon by the ball groove 301 and the transition part (guide groove 304) between the ball groove 301 and the ball groove 301.

[0034] refer to Figure 4-Figure 6 Embodiment 2: Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that a ball 233 is formed at the end of the second magnetic member 232. At this time, the first magnetic member 231 and the second magnetic member 232 are preferably magnetic components formed by metal magnetization. The end of the second magnetic member 232 is polished to form a ball head or hemispherical head structure. When in use, it can be combined with the application of lubricating oil to enhance the smoothness of the sliding friction between the ball 233 and the ball groove 301.

[0035] refer to Figure 1-Figure 4 Specifically, the rotating component 3 includes a bracket base 31 and a flip bracket 32, wherein the ball groove 301 is arranged at the outer periphery of the bracket base 31, and the inner side of the bracket base 31 is recessed to form a bracket groove 311, and the flip bracket 32 ​​is flipably connected to one side of the bracket groove 311 through a hinge assembly 4 and can be embedded in the bracket groove 311.

[0036] refer to Figure 1 , Figure 3 and Figure 4Specifically, an upper annular clamping edge 302 and a lower annular clamping edge 303 are respectively provided on the outer periphery of the bracket base 31 and the upper and lower ends of the ball groove 301, wherein an arc center track 3A is formed between the upper annular clamping edge 302 and the lower annular clamping edge 303, and an annular axial edge 102 is provided on one side of the first assembly groove 110 corresponding to the position of the arc center track 3A. In this way, a circular limiting structure is formed, and the rotating component 3 will not fall out and can rotate relative to the bracket shell body 100. When rotating, the flip bracket can be opened, and the flip bracket can be held by hand to drive the bracket base to rotate, so that the rotation of the flip bracket relative to the bracket base and the rotation of the rotating base relative to the bracket shell body can be completed. In this way, the support angle of the flip bracket can be adjusted at multiple angles.

[0037] refer to Figure 1 , Figure 3 and Figure 4 Specifically, the diameter of the upper annular clamping edge 302 is larger than the diameter of the lower annular clamping edge 303, or the diameter of the lower annular clamping edge 303 is larger than the diameter of the upper annular clamping edge 302. The larger diameter of one of the annular clamping edges is set so that during installation, the side with the smaller diameter is used as the head to assemble toward the position of the annular shaft edge 102. The rotating component 3 can be installed in the first assembly groove 110 by machine pushing or manual squeezing, so that it can be assembled successfully relatively easily.

[0038] refer to Figure 1 and Figure 3 Specifically, a rotation groove 312 is also provided on one side of the bracket groove 311, and the hinge assembly 4 includes a rotation piece 41, a blocking piece 42 and a rotating shaft 43. One side of the rotation groove 312 is recessed to form an axis embedding groove 44. The rotation piece 41 includes a connecting portion 411 and a rotating hole portion 412. The rotating shaft 43 passes through the rotating hole portion 412, and the connecting portion 411 is fixedly connected to one side of the flip bracket 32. Both sides of the rotating shaft 43 can be rotatably embedded in the axis embedding groove 44, and the blocking piece 42 is fixedly blocked on the outside of the axis embedding groove 44.

[0039] refer to Figure 3 Specifically, when the ball 233 is on the outside of the damping groove 22, because there is still a gap between the notch of the damping groove 22 and the ball groove 301, the split ball 233 is easy to move to the sides of the damping groove 22 when rotating for a long time, thereby affecting the normal rotation of the subsequent ball 233. Here, a limiting block 211 is provided on one side of the damping mounting seat 21 and on both sides of the ball 233, and a rolling groove 212 for the ball 233 to rotate is formed between the limiting blocks 211 on both sides, wherein the limiting block 211 just cooperates with the arc center track 3A, or just fits tightly against the outer peripheral part of the ball groove 301, so that the ball can be completely confined between the rolling groove 212 and the arc center track 3A.

[0040] refer to Figure 3 Specifically, because the bottom position of the ball groove 301 and the arc surface between two adjacent ball grooves 301 vary in height, when the ball 233 enters the second ball groove 301 from the first ball groove 301, the suspended ball assembly 23 is compressed. However, when the ball 233 comes out of the previous ball groove 301 and is about to leave the groove surface position of the ball groove 301, because the ball 233 is a hard material component and the ball groove 301 is also a hard material component, the two The latter will produce a certain amount of friction, which will affect the overall service life of the device. Here, a guide groove 304 is provided between the two ball grooves 301 to help the bracket base 31 to elastically fit the ball 233 between the ball grooves 301 with less friction when the bracket base 31 rotates. On the one hand, the guide groove 304 can reduce the friction of the groove surface when the ball 233 comes out of the previous ball groove 301, and on the other hand, it can reduce the friction between the ball 233 and the rotating component 3, thereby increasing the service life of the entire device.

[0041] refer to Figure 1 and Figure 3 Specifically, an identification component 33 is further provided on the inner side of the bracket base 31. The identification component 33 is made of a transparent material and is a logo piece arranged on the inner side of the bracket groove 311. In this embodiment, the identification component 33 made of a transparent material can display the product logo at the bottom of the bracket shell, or the identification component is made of a non-transparent material, is printed with a brand logo and is arranged on the inner side of the bracket groove 311. In this embodiment, a customized brand logo can be placed on it.

[0042] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
