Specifically, as shown in fig. 1, the gravity bracket 100 includes a bracket base 10, a supporting arm 20 disposed in a vertical direction of the bracket base 10 for supporting an electronic product, and a left clamping arm 30 and a right clamping arm 40 disposed opposite to each other in a horizontal direction of the bracket base 10. The support arm 20 of the gravity bracket 100 is located at the bottom of the whole bracket seat 10 for supporting the weight of the electronic product, and the horizontal left and right clamping arms 30 and 40 disposed at two sides are respectively abutted against the sides of the electronic product from two sides in the horizontal direction, thereby playing a role in fixing the electronic product at three points. The gravity bracket 100 provided by the invention further comprises a rotating member 50 which is arranged in the center of the bracket seat 10 and can rotate relative to the bracket seat 10, wherein the rotating member 50 is provided with a first chute 51 connected with the supporting arm 20, a second chute 52 connected with the left clamping arm 30 and a third chute 53 connected with the right clamping arm 40, the top of the supporting arm 20 is provided with a first protrusion 21 embedded in the first chute 51, the right side of the left clamping arm 30 is provided with a second protrusion 31 embedded in the second chute 52, the left side of the right clamping arm 40 is provided with a third protrusion 41 embedded in the third chute 53, and the supporting arm 20 moves downwards to drive the rotating member 50 to rotate so that the second protrusion 31 embedded in the second chute 52 and the third protrusion 41 embedded in the third chute 53 respectively drive the left clamping arm 30 and the right clamping arm 40 to move along the horizontal direction. The rotating member 50 is arranged to enable the left clamping arm 30 and the right clamping arm 40 of the gravity bracket 100 to be driven by the supporting arm 20 to move relatively, thereby playing a role in automatically clamping electronic products. The rotating member 50 achieves the function of moving in the horizontal direction by moving in the vertical direction, and can also play a limiting role.

Specifically, as shown in fig. 2 and 3, three different arc-shaped sliding grooves of a first sliding groove 51, a second sliding groove 52 and a third sliding groove 53 are provided on the rotating member 50, and the rotating member 50 is connected with the support arm 20 through the first sliding groove 51 and the first protrusion 21. The support arm 20 is arranged between the rotation element 50 and the support base 10, so that a first projection 21 is provided on the side of the support arm 20 facing the rotation element 50, by which first projection 21 the connection between the first projection 21 and the support arm 20 is realized, which engages in a first slide groove 51 of the rotation element 50. Therefore, when the support arm 20 receives the gravity generated after the electronic product is placed, the support arm 20 moves downward in the vertical direction. During the downward movement of the support arm 20, the rotating member 50 is driven to rotate relative to the bracket base 10, and during the rotation, the rotating member 50 rotates counterclockwise along the center of the bracket base 10 due to the arrangement direction and the arc-shaped effect of the first chute 51. Next, the left and right clamp arms 30 and 40 provided in the horizontal direction of the bracket base 10 are respectively located at the left and right sides of the bracket base 10, wherein the left and right clamp arms 30 and 40 are also provided between the rotating member 50 and the bracket base 10, so that the second protrusion 31 is provided on the opposite face of the side of the left clamp arm 30 near the rotating member 50, the third protrusion 41 is provided on the opposite face of the side of the right clamp arm 40 near the rotating member 50, and the second protrusion 31 is provided in the second slide groove 52, and the third protrusion 41 is provided in the third slide groove 53. When the rotating member 50 is driven by the downward movement of the support arm 20 to rotate counterclockwise along the center of the bracket base 10, the second protrusion 31 located in the second sliding groove 52 moves rightward along the horizontal direction along the arc track and the counterclockwise direction of rotation of the second sliding groove 52, and the third protrusion 41 located in the third sliding groove 53 moves leftward along the horizontal direction along the arc track and the counterclockwise direction of rotation of the third sliding groove 53, so that the support arm 20 moves downward to realize horizontal opposite movement between the left clamping arm 30 and the right clamping arm 40.

As shown in fig. 2, the arc-shaped arrangement of the first sliding groove 51 determines that the rotation member 50 can rotate counterclockwise around the center of the bracket base 10 when the supporting arm 20 moves downward. And the first chute 51 also determines the distance the support arm 20 can move downward. The first chute 51 not only determines the rotation direction of the rotating member 50, but also determines the moving distance of the support arm 20, thereby performing both driving and limiting functions. The arrangement of the second chute 52 and the third chute 53 determines that the left clamp arm 30 in the second chute 52 can move in the horizontal direction toward the center of the holder 10, i.e., in the horizontal direction to the right, and the right clamp arm 40 in the third chute 53 can move in the horizontal direction toward the center of the holder 10, i.e., in the horizontal direction to the left, when the rotating member 50 rotates counterclockwise. The second chute 52 and the third chute 53 not only determine the movement between the left clamping arm 30 and the right clamping arm 40, but also ensure that the left clamping arm and the right clamping arm move along the horizontal direction, and further ensure that the left clamping arm and the right clamping arm move in opposite directions, thereby achieving the clamping effect. The second chute 52 and the third chute 53 also play a limiting role, and the distance set by the second chute 52 and the distance set by the third chute 53 also determine the effective distance by which the left clamping arm 30 and the right clamping arm 40 can move in the horizontal direction. Therefore, the rotating member 50 is provided to function as a means for converting the movement of the support arm 20 in the vertical direction into the movement in the horizontal direction between the left clamp arm 30 and the right clamp arm 40, and to function as a means for limiting the movement distance between the support arm 20, the left clamp arm 30, and the right clamp arm 40. Moreover, the second chute 52 and the third chute 53 on the rotating member 50 can prevent the left clamping arm 30 and the right clamping arm 40 from swinging, and ensure that the left clamping arm 30 and the right clamping arm move along the horizontal direction, thereby achieving the function of clamping the side surface of the electronic product.
