[0031] As Figure 2 As shown and Figure 3 Rotating shaft assembly 7 includes main shaft 10, and the two ends of main shaft 10 are fixedly connected with the cavity wall of containing cavity 5, and fan-shaped slot 11 is provided on the end face of main shaft 10, fan-shaped slot 11 extends along the length direction of main shaft 10, and the lateral side of fan-shaped slot 11 is arranged in parallel with the fixed tertiary motherboard 3 after rotation, and the central angle of fan-shaped slot 11 is not less than 90 degrees.

[0032] Coaxially rotating sleeve 12 is sleeved on the outside of main shaft 10, limiting rib plate 13 is provided on the inner wall of rotating sleeve 12, limiting rib plate 13 is arranged in fan-shaped slot 11, and rotating sleeve 12 outer wall is fixedly connected with supporting arm 8, and supporting arm 8 is arranged in parallel with the lateral side of fan-shaped slot 11.

[0033] As a first embodiment, supporting arm 8 is arranged in secondary motherboard 2 by rotating setting of rotating shaft assembly 7 without moving height, supporting arm 8 rotates around main shaft 10 by rotating sleeve 12, thereby completing the operation from rotating out of containing cavity 5 to horizontal position, to set supporting arm 8 end portion below electronic camera 4 to carry out carrying work.

[0034] Specifically, when the rotating sleeve 12 rotates, the limiting ribs 13 cannot continue to rotate when they are in contact with the horizontal edges of the fan-shaped slot 11 on the main shaft 10, thereby forming a limiting effect and making the support arm 8 horizontal. The first main plate 1, the second main plate 2, and the third main plate 3 can be connected by rotating joints with limiting functions, so that they can be fixed at the rotated positions.

[0035] As shown in Figure 4 , as a second embodiment, the rotating shaft assembly 7 includes an end shaft 14, one end of which is rotatably connected to the cavity wall of the accommodating cavity 5, and the other end of which is fixedly arranged on both sides of the end of the support arm 8, and the end shaft 14 is externally provided with a locking assembly 15 for fixing the rotated position of the end shaft 14.

[0039] In this embodiment, as shown in Figure 4 , the support arm 8 has more rotating angles and fixed positions, and through the rotation of the end shaft 14 in the longitudinal through hole 16, the support arm 8 can be rotated more than 90 degrees, and through the sliding of the end shaft 14 in the longitudinal through hole 16, the support arm 8 can be brought closer to and farther away from the electronic camera 4, thereby making the shooting more flexible in different scenes and making the shooting effect better. Moreover, the position of the support arm 8 after moving and rotating is realized by the screw sleeve 18 rotating into and pushing the pressing gasket 17.

[0040] Specifically, when the support arm 8 is moved and rotated to a preset position, the rotating screw sleeve 18 pushes the compression gasket 17 against the side of the secondary main plate 2, and the height position of the support arm 8 is fixed by the abutting force and friction force between the compression gasket 17 and the side of the secondary main plate 2. Further, the friction force between the end of the screw sleeve 18 and the rough particles 19 on the surface of the compression gasket 17 is increased by the contact between the end of the screw sleeve 18 and the rough particles 19 on the surface of the compression gasket 17, the difficulty of relative rotation between the two is increased, and the position of the support arm 8 after rotation is fixed by pushing the screw sleeve 18 and compressing the compression gasket 17 to increase the abutting force between the two, so that the support arm 8 can be in a position parallel to the tertiary flat plate. In actual production, the support arm 8 can be made of lightweight materials to make the overall weight lighter, thereby achieving better locking effect.
