[0020] Reference Figures 1-5 A bracket with an automatic retraction function includes a base 10, a slide 20, multiple leg tubes 30, multiple support rods 40, and multiple drive components 50; The upper end of the base 10 is provided with a plurality of first rotation positions 61 and 1 / 4 bolts 14, which are used to connect photographic equipment. The slide 20 is movably disposed at the lower end of the base 10 and has a plurality of second rotation positions 62 arranged circumferentially thereon; One end of the foot tube 30 is rotatably connected to the first rotating position 61, the middle section is provided with a third rotating position 63, and the other end extends outward; One end of the strut 40 is rotatably connected to the second rotation position 62, and the other end is rotatably connected to the third rotation position 63; The driving component 50 is disposed between one end of the foot tube 30 and the base 10, and is used to provide the driving force for the foot tube 30 to rotate inward and retract. When the slide 20 abuts against the plane, the foot tube 30 can rotate outward to unfold; or, when the base 10 separates from the plane, the foot tube 30 can rotate inward to retract under the action of the drive member 50.

[0021] In this utility model, reference is made to Figure 1 and Figure 5 This is a schematic diagram of the bracket in its folded state. In this state, the legs 30 rotate inward to fit against the base 10, thus reducing the overall size for easy storage and portability. When needed, the bracket is placed on a flat surface with the slide 20 facing the plane. The base 10 needs to be pushed downward to overcome the force of the drive unit 50 until the legs 30 rotate outward and unfold under the pushing action of the slide 20. When the slide 20 abuts against the base 10, the legs 30 reach their maximum unfolding angle. Figures 2-4 The state of the bracket; after use, lift the base 10 upwards, causing the slide 20 and leg tube 30 to leave the plane. At this time, the leg tube 30 automatically rotates inwards and retracts under the action of the drive component 50, without the need for manual operation of the leg tube 30. Figure 1 and Figure 5 This greatly improves the ease of use of the bracket.

[0022] Reference Figures 3-5In some embodiments, a rotating shaft 31 is connected to one end of the foot tube 30. The rotating shaft 31 is rotatably mounted on the first rotating position 61. The driving component 50 is a torsion spring, which is sleeved on the rotating shaft 31 with one end abutting against the base 10 and the other end abutting against one end of the foot tube 30. Specifically, during assembly, the torsion spring is first placed between the two connecting parts at one end of the foot tube 30, and then the rotating shaft 31 is inserted between the two connecting parts at one end of the foot tube 30 and simultaneously passed through the torsion spring. In other embodiments, a first stop groove 13 is provided on the base 10, and a second stop groove 32 is provided on one end of the foot tube 30. One end of the torsion spring abuts in the first stop groove 13, and the other end abuts in the second stop groove 32. The displacement of the torsion spring is limited by the first stop groove 13 and the second stop groove 32 to prevent the torsion spring from swaying left and right and affecting the unfolding and retraction of the foot tube 30, and also to avoid the generation of abnormal noise.

[0023] Reference Figures 1-5 In some embodiments, the base 10 includes a first base 11 and a second base 12 connected above the first base 11 via a first detachable structure 71. A plurality of first rotation positions 61 are formed between the first base 11 and the second base 12. During assembly, the torsion spring and the rotating shaft 31 are first installed on one end of the foot tube 30, then the rotating shaft 31 is placed into the first rotation position 61 on the first base 11, and finally the second base 12 is connected to the first base 11 via the first detachable structure 71, thus confining the rotating shaft 31 within the first rotation position 61. Preferably, the first detachable structure 71 is a bolt.

[0024] Reference Figures 2-5 In some embodiments, the slide 20 and the base 10 are connected by a telescopic assembly 80. The telescopic assembly 80 can extend axially downward when the foot tube 30 rotates inward to retract, or it can shorten axially upward when the foot tube 30 rotates outward to extend. Preferably, the telescopic assembly 80 includes a fixed tube 81 and a plurality of telescopic tubes 82. One end of the fixed tube 81 is connected to the base 10, and the plurality of telescopic tubes 82 are sequentially sleeved inside the fixed tube 81. The slide 20 is fixedly connected to the telescopic tube 82 located at the lowermost end. (Refer to...) Figures 3-5 In some embodiments, one end of the fixed tube 81 is connected to the base 10 via a fourth detachable structure 74. Preferably, the fourth detachable structure 74 is a bolt. Specifically, when the bracket is extended, the slide 20 and the base 10 will move closer to each other, and at this time, the multiple telescopic tubes 82 will shorten axially upward. When the slide 20 abuts against the lowermost end of the fixed tube 81, the foot tube 30 reaches its maximum extension angle. When the bracket is retracted, the slide 20 and the base 10 will move further apart, and at this time, the multiple telescopic tubes 82 will extend axially downward. When all the telescopic tubes 82 reach their maximum stroke, the foot tube 30 abuts against the base 10 and the fixed tube 81.

[0025] Reference Figures 2-5In some embodiments, the upper end of the slide 20 is provided with a plurality of slots 21, and the lower end of the slide 20 is connected to the base 10 through a second detachable structure 72 to form a plurality of second rotation positions 62. Preferably, the second detachable structure 72 is a bolt. During assembly, one end of the support rod 40 is first placed into the second rotation position 62, and then the slide 20 is connected to the base 10 with bolts. In a preferred embodiment, the slide 20 is connected to the telescopic tube 82 located at the lowermost end by bolts, thereby limiting one end of the support rod 40 within the second rotation position 62. Finally, the other end of the support rod 40 is assembled into the third rotation position 63 located in the middle section of the foot tube 30.

[0026] Reference Figures 3-5 In some embodiments, the middle section of the foot tube 30 is provided with a pin groove 33 and also includes a pin block 34. The pin block 34 is connected to one end of the pin groove 33 through a third detachable structure 73, so that a third rotation position 63 is constructed between the pin block 34 and the other end of the pin groove 33. During assembly, the other end of the support rod 40 is first held against the other end of the pin groove 33, then one end of the pin block 34 is abutted against the other end of the support rod 40, and finally the other end of the pin block 34 is connected to one end of the pin groove 33 through the third detachable structure 73, so that the other end of the support rod 40 is limited within the third rotation position 63.

[0027] Reference Figures 2-4 In some embodiments, an anti-sway structure 90 is provided between two adjacent leg tubes 30 to limit the swaying of the leg tubes 30 when they rotate inward to retract. Preferably, the anti-sway structure 90 includes a groove 91 on one side of the leg tube 30 and a protrusion 92 on the other side of the leg tube 30. The protrusion 92 on the leg tube 30 can extend into the groove 91 on the other leg tube 30 when the leg tube 30 rotates inward to retract. Specifically, when the bracket is in the retracted state, the protrusion 92 on one of the two adjacent leg tubes 30 will extend into the groove 91 on the other of the two adjacent leg tubes 30. Since the drive member 50 always applies an inward rotational driving force to the leg tubes 30, the cooperation between the protrusion 92 and the groove 91 can prevent the leg tubes 30 from swaying during carrying, further improving the user experience.

[0028] The advantages of this utility model are: the above structure allows the bracket to be placed on a plane and enter the unfolded state, which can support the photography equipment; and when the bracket leaves the plane, it automatically enters the retracted state under the action of the driving component, without the need for manual operation, which greatly improves the convenience of use and meets the needs of use.

[0029] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
