DETAILED DESCRIPTION

[0021] The typical embodiments embodying the features and advantages of the present application will be described in the following description. It should be understood that the present application can be varied in a wide range of embodiments, none of which depart from the scope of the present application, and that the description and drawings are to be considered as illustrative in nature, and not as restrictive to the present application.

[0022] In the description of the present application, the terms "upper", "lower", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0023] Please refer to Figure 1 and Figure 2 The present application provides a technical solution: a multifunctional central axis of tripod, comprising a central axis body 1, the cross section of the central axis body 1 is Y-shaped profile structure, two symmetrical wing parts 5 and a center part 6 together form a Nato specification sliding groove interface structure, which can be compatible with camera accessories of Nato specification clamp (adapted to the general Nato claw buckle on the market). Camera accessories can be clamped and assembled with the central axis body 1 through the Nato sliding groove interface structure, such as camera microphone, light or display, which can be directly connected and installed on the central axis body 1 for use, thereby providing mounting positions for the installation of other auxiliary photography equipment, without the need for additional auxiliary installation structure, which is beneficial to reduce the volume and the carrying of other accessories, and the structure is more portable.

[0024] The cross section of the central axis body 1 is Y-shaped profile structure formed by three arc segments connected end to end, the Y-shaped profile formed by the three arc segments can form multiple-point contact, which can better disperse the load, reduce local wear, and enhance the stability during sliding. The outer surface of the central axis body 1 is smooth arc surface, which not only can reduce the weight of the central axis body 1 as a whole, but also can reduce friction, so that the central axis body 1 is more smooth when inserted and assembled.

[0025] Please refer to Figure 1, one end of the central shaft body 1 is connected with a photography holder 2, the photography holder 2 can adopt a spherical holder or other holder with panoramic function in the prior art, the photography holder 2 in the present application is preferably an inverted holder in the prior art, and one end of the central shaft body 1 is threadedly connected with the sphere of the inverted holder. The design of integrating the rotatable inverted holder clamp seat at one end of the central shaft body 1 realizes stable fixation through rigid connection by threads, and meanwhile, the rotation function of the photography holder 2 is utilized, so that the central shaft body 1 can quickly adjust the pitch, roll and horizontal rotation angle, so that the shooting device (such as a camera, a lens) can quickly aim at the target object, which is suitable for dynamic shooting or complex scenes, and the integrated design saves the additional adapter, thereby improving the work efficiency. It can be widely applied to scenes requiring high-precision positioning and flexible operation, such as film and television shooting and industrial detection.

[0026] Please refer to Figure 2 , the other end of the central shaft body 1 is provided with a threaded hole 3, the threaded hole 3 is connected with a stop piece 4, the stop piece 4 adopts a screw in the prior art, and the outer edge of the nut of the screw is higher than the lowest point of the arc surface, so that the maximum movement stroke of the object on the central shaft body 1 can be limited by the screw, thereby avoiding disengagement from the central shaft body 1.

[0027] Please refer to Figure 3 and Figure 4 Unlike the above embodiments, the outer edge of the other side wing of the central shaft body 1 is provided with a tooth groove structure 8 along the length direction, and a device such as a camera (the shooting device is connected and assembled on the top of the driving assembly 9) can be controlled to move along the length direction of the central shaft body 1 by the driving assembly 9, the driving assembly 9 can adopt the driving assembly 9 formed by the cooperation of a motor and a gear in the prior art, the motor drives the gear to rotate, and the gear rotates to realize transmission by engaging with the tooth groove structure 8, so as to drive the device to slide along the central shaft body 1 for shooting.

[0028] Please refer to Figure 5 A photography kit comprises a tripod central shaft slide rail 10, the tripod central shaft slide rail 10 adopts the multifunctional tripod central shaft as described above. By inserting the central shaft body 1 into the tripod as a central shaft, the central shaft body 1 is combined with the tripod, so that the device structure is greatly simplified, and the volume and weight are lightened. Compared with the traditional scheme that the slide rail and the tripod need to be separately carried when shooting micro dynamic video (such as moss, tree bark pattern, clock rotation, etc.), the present design significantly reduces the carrying burden.

[0029] Please refer to Figure 6A photography kit comprises a two-in-one tripod 11 with stabilizer function, and a multifunctional tripod middle shaft as described above is inserted into the two-in-one tripod 11. The handle of the stabilizer (which can adopt the handle structure of a small Steadicam stabilizer in the prior art and has multiple degrees of freedom) can be directly clamped on the middle shaft body 1 through a Nato-spec slide groove interface structure on the middle shaft body 1 and used. When the handle is taken off alone, the tripod can be used as a conventional tripod. When the handle is clamped on the assembly shaft 12 (which has the same structure as the middle shaft body 1 and can rotate relative to the middle shaft body 1) of the middle shaft body 1, the whole tripod can be used as a handheld stabilizer. The present application has all the functions of the stabilizer and the tripod without increasing the volume and weight, and the two-in-one structure solves the pain point of photographers carrying multiple devices when going out and greatly reduces the burden of photographers when going out, so that the work is more relaxed.

[0030] Finally, it should be pointed out that the above-described embodiments are only preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application, and any non-essential changes and substitutions made by those skilled in the art on the basis of the present application all belong to the scope of protection required by the present application.
