[0019] Reference Figure 1 and Figure 2 In a preferred embodiment, the rotating mechanism includes a worm gear ring 22, which is sleeved on the outer surface of the first connecting column 21. The worm gear ring 22 is connected to the inside of the connecting chamber 16. The inside of the connecting chamber 16 is horizontally rotatably connected with a worm 5. The worm 5 is horizontally arranged. The worm 5 cooperates with the worm gear ring 22. One end of the worm 5 is sleeved on one side of the inside of the connecting chamber 16. One end of the surface of the base 1 is rotatably connected with a second knob 51. The second knob 51 is fixedly connected to one end of the worm 5 and is used to limit the rotation of the connecting rod 2, so that the device can be unfolded or folded.
[0020] Reference Figure 1 and Figure 2In a preferred embodiment, the other end of the connecting rod 2 is hinged with a second connecting column 32, and the surface of the second connecting column 32 is fixedly connected to a mounting seat 31, and the top of the mounting seat 31 is installed with a camera device 3. A screw rod is sleeved inside the other end of the connecting rod 2, and the other end surface of the connecting rod 2 is symmetrically connected to the first knob 4 and the matching cap 41 on both sides for rotation. The first knob 4 is fixedly connected to one end of the screw rod, and the matching cap 41 is sleeved on the surface of the screw rod. The matching cap 41 cooperates with the screw rod to adjust the angle of the camera device 3.
[0021] Reference Figure 2 and Figure 3 In a preferred embodiment, the sliding mechanism includes a pull rod 61, and slide grooves 12 are provided on opposite sides of the connecting groove 11. The two ends of the cover plate 6 slide in the two slide grooves 12 respectively. An expansion area 18 is provided at the top of the connecting groove 11.

By rotating and tightening, the angle of the camera device 3 is limited. When the connecting rod 2 rotates, the cover 6 is driven to slide horizontally under the connection of the pull rod 61, so that the cover 6 no longer blocks the expansion area 18. At this time, the storage device or power supply equipment can be installed at the expansion area 18 for use. When not in use, the worm 5 can be driven to rotate by rotating the second knob 51 in the opposite direction, so that the connecting rod 2 can be rotated downward and parallel to the base 1. At the same time, under the connection of the pull rod 61, the worm 5 can slide to the expansion area 18 to cover the expansion area 18, thereby improving the protection of the expansion area 18 and improving the use effect of the device.
