[0031] Specifically, positioning mechanism 4 includes extrusion plate 41, positioning rod 42, pull rod 43 and compression spring 44, the inside of first cross beam 1 and second cross beam 2 is set with extrusion slot symmetrically, extrusion plate 41 is located in the inside of extrusion slot, the both sides of clamping plate 3 are set with positioning hole equidistantly, one end of positioning rod 42 is fixedly connected with extrusion plate 41, the other end of positioning rod 42 is slidably inserted into the inner cavity of extrusion slot and connected with positioning hole, one end of pull rod 43 is fixedly connected with extrusion plate 41, the other end of pull rod 43 is slidably inserted into the inner wall of extrusion slot and connected, compression spring 44 is sleeved on the outside of pull rod 43, one end of compression spring 44 is fixedly connected with extrusion plate 41, the other end of compression spring 44 is fixedly connected with the inner wall of extrusion slot, compression spring 44 is always in compression state, so as to provide a stable elastic force to multiple positioning rods 42 by extrusion plate 41, so as to make positioning rod 42 and positioning hole stably inserted, so as to stably connect first cross beam 1 and second cross beam 2 together, when needing to disassemble, just pull extrusion plate 41 by pull rod 43, so that positioning rod 42 is separated from positioning hole, so adjacent two cross beams can be disassembled, convenient operation. Example

[0032] Based on Example 1, such as Figures 3-4 As shown, the positioning mechanism 4 also includes a rotating rod 45, a pull ring 46, a limiting rod 47, and a limiting plate 48. The rotating rod 45 is rotatably disposed inside the pull rod 43. The cross-section of the rotating rod 45 is T-shaped. The rotating rod 45 facilitates the rotation of the pull ring 46 without affecting the normal use of the pull rod 43. The T-shaped cross-section also enhances the structural strength of the rotating rod 45, ensuring that it is not easily deformed or damaged under stress. The pull ring 46 is fixedly connected to one end of the rotating rod 45. The pull ring 46 can pull the pull rod 43 through the T-shaped rotating rod 45, thereby causing the pressing plate 41 to move the positioning rod 42 for disassembly. The limiting rod 47 is symmetrically fixedly connected to the opposite side of the pull ring 46. The limiting plate 48 is fixedly connected to one end of the limiting rod 47. Insertion holes are equidistantly opened on both sides of the first crossbeam 1 and the second crossbeam 2. Limiting grooves are opened on the inner wall of the insertion holes. The limiting grooves are arc-shaped when viewed from the side and arc-shaped when viewed from the front. The limiting plate 48 is a T-shaped groove with a sliding connection between the insertion hole and the inner cavity of the limiting groove. The first crossbeam 1 and the second crossbeam 2 have positioning holes equidistantly opened on both sides. The limiting plate 48 and the inner cavity of the positioning hole cooperate with each other. When the limiting plate 48 passes through the insertion hole and is inserted into the limiting groove, the T-shaped rod formed by the limiting rod 47 and the limiting plate 48 can be used to limit the movement and prevent the pull ring 46 from being easily pulled. When assembling the crossbeam, the limiting plate 48 can be pulled out from the insertion hole and then snapped into the positioning hole. At this time, the positioning rod 42 being pulled will not affect the normal snapping and insertion of the snapping plate 3. The limiting plate 48 is slidably connected to the limiting groove through the insertion hole to form a stable limiting structure. This design allows the pull ring 46 to remain fixed when not under force, preventing accidental loosening caused by misoperation, facilitating the installation between crossbeams and making it easy to use.

[0033] Furthermore, a rubber sleeve 5 is fixedly fitted on the outer wall of the pull ring 46. The outer wall of the rubber sleeve 5 has anti-slip texture to increase the friction between the user's hand and the rubber sleeve 5, preventing inconvenience or accidental drop during operation due to slippage.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
