[0019] like Figures 1 to 4 The diagram shows a triangular support structure, including a support gimbal 1 for placing a mobile phone or camera; and includes support legs 2, a central shaft 3, a sleeve 4, and connecting ribs 5.

[0020] The support legs 2 are arranged in a circular array on the support gimbal 1. The top of the support legs 2 is hinged to the support gimbal 1 to support the support gimbal 1.

[0021] The central axis 3 is set vertically on the bottom of the support gimbal 1, and the central axis 3 is located at the center of the bottom of the support gimbal 1.

[0022] The sleeve 4 has a cylindrical structure, with an opening at the top and a guide hole along the axial direction that mates with the central shaft 3; the bottom of the central shaft 4 is inserted from the top of the sleeve and slides into the guide hole of the sleeve 4.

[0023] There are several connecting ribs 5, and the connecting ribs 5 are distributed in an array on the circumference of the sleeve 4; one end of the connecting rib 5 is hinged to the support foot, and the other end of the connecting rib 5 is hinged to the sleeve 4; the opening and closing of the support foot 2 is achieved by the relative sliding between the sleeve 4 and the central shaft 3.

[0024] The support gimbal 1 includes a support base 11 and a universal ball joint 12; the bottom edge of the support base 11 is provided with a first hinge groove 13 arranged in an array for mounting the top of the support leg 2, and a receiving hole for mounting the central shaft 3 is provided at the center of the support base 11; bolt holes are provided on the support base 11 near the edge, and bolts are passed through the support base 11 to connect with the universal ball joint 12 provided on the upper surface of the support base 11, so as to realize the installation of the universal ball joint 12 on the upper surface of the support base 11.

[0025] The top of the central shaft 3 is thickened to form a thickened upsetting head. The top of the central shaft 3 is embedded in the receiving hole of the support base 11, and the end of the central shaft 3 is locked and fixed to the receiving hole on the support base 11 by bolts through a disc-shaped locking plate 31 with a central hole.

[0026] The sleeve 4 includes a connecting rib hinge seat 41, a support spring 42, and a cylindrical unit 43. The connecting rib hinge seat 41 is cylindrical and has several second hinge slots 44 arranged in a ring array around its circumference. The connecting rib hinge seat 41 is bolted and installed on the top of the cylindrical unit 43. The cylindrical unit 43 is cylindrical and has a guide hole at its center along the axial direction that slides with the central shaft 3. The outer contour of the top of the cylindrical unit 43 is provided with a mounting plate 45 that mates with the connecting rib hinge seat 41, and the mounting plate 45 has a spring receiving hole corresponding to the position of the second hinge slot. The support spring 42 is disposed in the spring receiving hole on the mounting plate 45 and is used to support the end of the connecting rib 5 that is hinged in the second hinge slot 44.

[0028] The working principle of this utility model is as follows: By employing a sliding fit between the sleeve and the central shaft, when the tripod is in its folded state, the bottom end of the sleeve protrudes beyond the bottom end of the support leg. During the unfolding process, the bottom end of the sleeve first contacts the placement surface. By pressing down with one hand, the sleeve and the central shaft slide relative to each other, causing the connecting rib hinged between the sleeve and the support leg to extend outwards until the bottom end of the support leg is flush with the bottom end of the sleeve, thus enabling one-handed opening of the tripod. A spring is installed at the hinge point between the connecting rib and the sleeve to support the end of the connecting rib. This design ensures sufficient space and elastic support for the axial movement generated at the end of the connecting rib. When folding, simply lift the support platform; under the influence of gravity and the spring at the end of the supporting connecting rib, the sleeve automatically slides down, thus folding the tripod.

[0029] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
