Then, control the first adjustment locking member to lock and fix the first support rod and the second support rod, and the connection is stable and firm; when not in use, fold the second support rod and store it in the first support rod, and then control the first adjustment locking member to lock and fix the first support rod and the second support rod, which not only saves space but also is flexible to use; then, after adjusting the angle between the first support rod and the connecting portion according to the user's usage habit, control the second adjustment locking member to lock and fix the first support rod and the connecting portion, and a better viewing angle can be obtained, and the user experience is better.

[0031] In this embodiment, the central axis of the connecting portion 21 is perpendicular to the extension line of the central axis of the suction cup assembly 20; the first support rod 11 rotates radially on the suction cup assembly 20 with the central axis of the connecting portion 21 as the center; users can greatly adjust the mobile phone connected to the bracket to a position below the air outlet, avoiding the mobile phone blocking the driving line of sight.

[0032] AsFigure 3 As shown, the connecting portion 21 protrudes from the middle of the top of the suction cup assembly 20; on both sides of one end of the first support rod 11, first connecting ears 112 extending towards the connecting portion 21 are symmetrically provided; a first receiving cavity 113 for receiving the connecting portion 21 is formed between the two first connecting ears 112; the connecting portion 21 is limited in the first receiving cavity 113 by the second adjusting and locking member 40; the installation is simple and convenient for positioning the first support rod.

[0034] In order to increase the friction force between the first connecting ear 112 and the connecting portion 21, a plurality of first convex teeth (not shown in the figure) circumferentially distributed with the axis of the adjusting screw rod 43 as the center are provided on the surface of the first connecting ear 112 facing the connecting portion; as Figure 4 shown, a plurality of first tooth grooves 211 are provided on one surface of the connecting portion 21; the plurality of first tooth grooves 211 are respectively adapted to any plurality of first convex teeth 114, and can stably connect the first support rod 11 and the connecting portion 21.

[0035] Furthermore, the first adjusting and locking member can also adopt the same locking connection structure as the second adjusting and locking member to connect the first support rod and the second support rod, which is convenient for users to adjust.

[0036] Optionally, in another embodiment, the connecting portion 21 is a rotating shaft vertically fixed on the suction cup assembly 20; one end of the first rod 11 is movably sleeved on the connecting portion 21; the central axis of the connecting portion 21 coincides with the extension line of the central axis of the suction cup assembly 20; the first rod 11 rotates circumferentially around the central axis of the connecting portion 21 on the suction cup assembly 20. The folding frame of this bracket has a wider range of movement.

[0037] As Figure 3-5 shown, in one embodiment, the suction cup assembly 20 includes a top cover 22 fixedly connected to the connecting portion 21, a skeleton 23 fixedly connected to the top cover 22, and a suction cup 24 tightly connected to the periphery of the skeleton 23; a rotating bracket 25 is rotatably arranged between the top cover 22 and the skeleton 23; a positioning hole 231 is provided at the center of the skeleton 23; the center of the rotating bracket 25 has a through hole 251 communicating with the positioning hole 231, and two arc-shaped guide rails 252 surrounding the through hole 251 are provided on the upper surface of the rotating bracket 25; the height of the guide rail 252 gradually increases in the clockwise direction; the suction cup assembly 20 further includes a pumping member 26; the pumping member 26 includes a chassis 261 arranged between the skeleton 23 and the suction cup 24, and a connecting column 262 fixedly connected to the chassis 261 and passing through the positioning hole 231 and then passing through the through hole 251; a cross bar (not shown in the figure) extending to both sides of the connecting column 262 is provided through the end of the connecting column 262 protruding from the through hole 251; both ends of the cross bar (not shown in the figure) are respectively movably mounted on the corresponding guide rails 252; low-position grooves and high-position grooves (not shown in the figure) for positioning the cross bar are provided on the guide rails located on the moving track of the cross bar; when the cross bar moves to the low-position groove, the chassis is located on the side close to the suction cup, and at this time the adsorption force of the suction cup 24 decreases; when the cross bar moves to the high-position groove, the chassis is located on the side close to the skeleton, and at this time the adsorption force of the suction cup 24 increases.

[0038] Specifically, rotate the rotating bracket clockwise, the rotating bracket drives its arc-shaped guide rail to push the cross bar to gradually rise, and the cross bar gradually moves towards the high-position groove. Based on the air extraction principle of a syringe, the chassis gradually rises with the cross bar, and the air between the suction cup and the skeleton is sucked away, increasing the adsorption force of the suction cup, so that the suction cup can firmly adhere to the plane, and the adsorption stability is high; on the contrary, rotate the rotating bracket counterclockwise, the rotating bracket drives its arc-shaped guide rail to push the cross bar to gradually descend, and the horizontal axis gradually moves towards the low-position groove, and the chassis gradually descends with the cross bar, thereby releasing the adsorption force of the suction cup. Adsorption and release of adsorption can be completed only by rotating the rotating bracket clockwise or counterclockwise, and the operation is convenient.

[0039] Furthermore, a plurality of positioning posts 232 extending in the direction of the rotating bracket 25 are circumferentially arranged on the upper surface of the skeleton 23; a plurality of sliding channels 253 slidably connected to the plurality of positioning posts 232 one by one are circumferentially arranged on the rotating bracket 25; the skeleton 23 is fixedly connected to the top cover 22 by passing the plurality of positioning posts 232 through the sliding channels 253; the rotating bracket 25 can rotate between the top cover 22 and the skeleton 23 through the cooperation of the plurality of positioning posts 232 and the corresponding plurality of sliding channels 253, with a simple structure and stable overall connection.

[0040] Furthermore, in order to prevent the rotating bracket from deviating from the center of the suction cup assembly during rotation, an annular positioning groove 233 adapted to the annular side wall outside the rotating bracket 25 is further provided on the upper surface of the skeleton 23; the rotating bracket 25 can rotate in the annular positioning groove 233.

[0041] Optionally, the top cover 22 includes an outer shell 221 and an inner shell 222 fixedly connected to the outer shell 221; a plurality of connecting shafts 223 corresponding to the positioning posts 232 one by one and a plurality of circumferentially arranged bumps 224 are circumferentially arranged on one side surface of the inner shell 222 facing the rotating bracket 25; the positioning posts 232 are fixedly connected to the corresponding connecting shafts 223 through fasteners, with a more stable connection, and the friction force of the rotating bracket 25 can be further increased through the bumps, and the damping force between the rotating bracket and the top cover can be achieved.

[0042] In another embodiment, the suction cup assembly 20 can also adopt the commonly used suction cup structure in the prior art, which will not be elaborated here.

[0043] It should be understood that those of ordinary skill in the art can make improvements or transformations according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
