[0032] In the terms of the present utility model, words such as "first" and "second" are only for descriptive purposes and cannot be construed as indicating or implying relative importance, nor as limiting the order of precedence.

[0033] A clamping mechanism provided by the utility model comprises an adapter 11 connected to a mobile phone holder, a clamping device 12 rotatably connected to the adapter 11 for clamping a mobile phone, and a damping device 13 connected between the adapter 11 and the clamping device 12. A through groove 111 is provided on the adapter 11. The clamping device 12 comprises a connecting plate 121 and a clamping assembly 122 rotatable on the connecting plate 121. One end of the connecting plate 121 away from the clamping assembly 122 is provided with a fixing plate 1211 extending into the through groove 111. The damping device 13 comprises a middle sleeve 131 connected in the fixing plate 1211 and a rotating shaft 133 connected in the adapter 11 and the middle sleeve 131. A cavity is provided in the middle sleeve 131. The damping device 13 further comprises a wear-resistant sheet 132 located between the rotating shaft 133 and the middle sleeve 131. The rotating shaft 133 and the wear-resistant sheet 132 are in interference connection in the inner cavity of the middle sleeve 131. The adapter 11 is used for connecting to the mobile phone holder, the clamping device 12 is used for clamping the mobile phone, and the damping device 13 is used for fixing the clamping device 12 on the adapter 11, so as to facilitate the clamping device 12 to stay at any position on the adapter 11. When assembling the clamping mechanism, first, install the middle sleeve 131 in the fixing plate 1211 of the connecting plate 121, and then extend the fixing plate 1211 with the installed middle sleeve 131 into the through groove 111. Further, sleeved the wear-resistant sheet 132 on the rotating shaft 133, and the rotating shaft 133 sleeved with the wear-resistant sheet 132 extends into the middle sleeve 131 from the adapter 11 respectively, so that the wear-resistant sheet 132 and the rotating shaft 133 are both in interference connection in the middle sleeve 131. On the one hand, the rotating shaft 133 extending into the middle sleeve 131 is used for connecting the connecting plate 121 to the adapter 11. On the other hand, it is convenient for the connecting plate 121 to be rotatably connected to the adapter 11. And due to the function of the wear-resistant sheet 132, when the connecting plate 121 rotates, the fixing plate 1211 drives the middle sleeve 131 to rotate, the middle sleeve 131 drives the wear-resistant sheet 132 to rotate, and the wear-resistant sheet 132 rotates along the circumference of the rotating shaft 133. The fixing plate 1211 and the wear-resistant sheet 132 generate frictional force so as to make the fixing plate 1211 produce a damping effect. At the same time, two rotating shafts 133 are respectively arranged on both sides of the adapter 11, so that both ends of the fixing plate 1211 are evenly stressed during rotation, avoiding the situation that one side of the fixing plate 1211 is not stressed and tilts. The above assembly structure is simple, can effectively improve the assembly efficiency, and improve the production capacity of the produced clamping mechanism.

[0034] There are two rotating shafts 133, and the two rotating shafts 133 are respectively connected to both sides of the adapter 11. One end of the rotating shaft 122 is connected to the inside of the adapter 11 and the other end is connected to the inner cavity of the middle sleeve 131. The fixing plate 1211 rotates on the two rotating shafts 133, which can prevent the fixing plate 1211 from swaying to the other side during rotation, so that the fixing plate 1211 can stably rotate on the rotating head.

[0035] The adapter 11 is provided with a first through hole 113 communicating with the through groove 111. The first through hole 113 is polygonal. The outer surface of the position where the rotating shaft 133 is connected to the adapter 11 is set to a polygonal shape matching the first through hole 113. The polygonal rotating shaft 133 is connected in the polygonal first through hole 113 to prevent the rotating shaft 133 from slipping in the adapter 11, so that when the connecting plate 121 rotates on the adapter 11, a stable damping effect can occur.

[0036] Please refer to Figure 3 , Figure 3 which is a perspective view of the connecting plate of the clamping mechanism of the present utility model. The fixing plate 1211 is provided with a second through hole 1212. The second through hole 1212 is polygonal. The outer surface of the middle sleeve 131 is set to a polygonal shape matching the second through hole 1212. The polygonal middle sleeve 131 is connected in the polygonal first through hole 113. When the connecting plate 121 rotates, it prevents the middle sleeve 131 from slipping in the fixing plate 1211.

[0037] There are two wear-resistant pieces 132. The two rotating shafts 133 also each include a connecting column connected in the middle sleeve 131. The two wear-resistant pieces 132 are respectively sleeved on the connecting columns of the two rotating shafts 133. When the fixing plate 1211 rotates, due to the action of the limit protrusions and the connecting column being in interference fit in the middle sleeve 131, the middle sleeve 131 drives the wear-resistant piece 132 to rotate, and the wear-resistant piece 132 rotates on the outer surface of the connecting column, so that a damping effect occurs when the fixing plate 1211 rotates.

[0038] The adapter 11 is further provided with a groove 114. The groove 114 is located below the through groove 111. The groove 114 is used to facilitate the rotation of the fixing plate 1211 and prevent the fixing plate 1211 from being unable to rotate in the adapter 11 after installation.

[0039] The wear-resistant piece 132 is provided with an opening. The wear-resistant piece 132 with the opening facilitates the rotating shaft 133 to extend into the wear-resistant piece 132. When the wear-resistant piece 132 with the rotating shaft 133 installed extends into the middle sleeve 131, the middle sleeve 131 presses the wear-resistant piece 132. Due to the opening, the wear-resistant piece 132 clamps the rotating shaft 133, so that the rotating shaft 133 is in interference fit in the middle sleeve 131.

[0040] The outer surface of the wear-resistant piece 132 is provided with a plurality of limit protrusions arranged along the circumference of the wear-resistant piece 132. The limit protrusions are used to increase the friction between the wear-resistant piece 132 and the middle sleeve 131, prevent the wear-resistant piece 132 from rotating in the middle sleeve 131, and enable the middle sleeve 131 to stably drive the wear-resistant piece 132 to rotate.

[0041] The adapter 11 is further provided with a third through hole 112 located outside the first through hole 113 and communicating with the first through hole 113. The damping device 13 is further provided with a decorative cover 134 sleeved outside the rotating shaft 133. The decorative cover 134 is located in the third through hole 112. The decorative cover 134 is used to enclose the rotating shaft 133 to make the appearance of the clamping device 12 more beautiful. The third through hole 112 is used to place the decorative cover 134 so that the decorative cover 134 is located inside the adapter 11 and the shape of the decorative cover 134 is more beautiful.

[0042] The wear-resistant piece 132 is made of a metal material, and the metal material has high hardness and wear resistance and can maintain stable performance under high stress and high wear conditions.

[0043] Working principle:

[0044] When assembling the clamping mechanism, first, install the middle sleeve 131 in the fixing plate 1211 of the connecting plate 121. Since the fixing plate 1211 is provided with a second through hole 1212 and the second through hole 1212 is polygonal, the outer surface of the middle sleeve 131 is also polygonal and matches the second through hole 1212. The middle sleeve 131 is connected in the second through hole 1212 to prevent the middle sleeve 131 from slipping in the fixing plate 1211. Further, insert the fixing plate 1211 with the installed middle sleeve 131 into the through groove 111, sleeve the wear-resistant piece 132 on the connecting column of the rotating shaft 133. Since the wear-resistant piece 132 is provided with an opening, it is convenient for the connecting column to extend into the wear-resistant piece 132. Then, insert the connecting column sleeved with the wear-resistant piece 132 through the third through hole 112 of the adapter 11. The connecting column passes through the first through hole 113 and extends into the middle sleeve 131. The rotating shaft 133 stays in the first through hole 113. When the wear-resistant piece 132 is located inside the middle sleeve 131, the wear-resistant piece 132 is squeezed by the middle sleeve 131 to close the opening and clamps the connecting column due to the squeezing force, so that the connecting column is in interference connection with the wear-resistant piece 132. Since the circumferential side of the wear-resistant piece 132 is provided with a limiting protrusion, when the connecting plate 121 rotates, the fixing plate 1211 drives the middle sleeve 131 to rotate, the middle sleeve 131 drives the wear-resistant piece 132 to rotate, and the wear-resistant piece 132 rotates around the circumferential side of the connecting column. The connecting column is in interference connection with the wear-resistant piece 132. When the wear-resistant piece 132 rotates on the connecting column, it can achieve a good damping effect, enabling the connecting plate 121 to stay at any position of the adapter 11 without tipping. Finally, install the decorative cover 134 in the third through hole 112 of the rotating shaft 133. The above structure is simple, can effectively improve the assembly efficiency and the production capacity of the production of the clamping mechanism. At the same time, the connecting plate 121 has a good damping effect when rotating on the adapter 11 and is more convenient to use.

[0045] In the clamping mechanism of this preferred embodiment, during the assembly of the clamping mechanism, the middle sleeve is installed in the fixed plate, the wear-resistant piece is sleeved on the rotating shaft, and the rotating shaft sleeved with the wear-resistant piece extends from the adapter into the middle sleeve. The middle sleeve squeezes the wear-resistant piece to clamp the rotating shaft, so that the rotating shaft is in interference fit with the wear-resistant piece, thereby enabling the connecting plate to have a good damping effect. The installation structure is simple, which can effectively improve the assembly efficiency and increase the production capacity of the clamping mechanism.

[0046] In summary, although the present utility model has been disclosed above with the preferred embodiments, the above preferred embodiments are not intended to limit the present utility model. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
