Although this method can buffer the force applied to the camera to a certain extent, the camera is not only subject to collision during use, but is also susceptible to external collision when not in use. The prior art focuses on protecting the camera during use, and the structure of the protective mechanism is single, which is not convenient for assisting other aspects of the camera, and the use effect is poor. Therefore, after research, a tilt photogrammetry device for preventing the lens from being cracked is provided. When in use, a hollow tube is installed on a support plate, and the camera is moved with a slider to adjust the use height of the camera, and the side plate and protective plate are used to wrap the camera when not in use. At this time, the support plate is placed upward, and the extension plate is slid out so that the camera is wrapped inside, thereby preventing the camera from being cracked after being hit by external factors, thereby solving the above defects.

[0032] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] In order to install the camera 20, the two sides of the slider 18 are rotatably connected to the mounting plate 19 through the second rotating rod 21. An inclined camera 20 is arranged on the lower side of the mounting plate 19. When the mounting plate 19 is rotated by the second rotating rod 21, the use position of the camera 20 can be adjusted.

[0036] Side panels 2 are provided on both sides of the support plate 1, and anti-collision mechanisms are connected to the other two sides of the support plate 1. When the anti-collision mechanism is in contact with the two side panels 2, an annular wrapping cover is formed to protect the camera 20 from collision. Specifically, the anti-collision mechanism includes protective plates 3 located on both sides of the support plate 1, and an extension plate 4 is slidably provided in an opening opened on one side of the protective plate 3, and a base 5 is provided on the lower side of the extension plate 4. When the camera 20 is not in use and is placed still, the support plate 1 can be placed upward, and the camera 20 is moved to a suitable position by the slider 18, so that the side panels 2 and the extension panels 4 can cover the camera 20, and the base 5 is placed on the desktop. At this time, the side panels 2 and the protective plates 3 form an annular protective cover to protect the camera 20 and prevent the camera 20 from being hit by external factors and causing breakage.

Therefore, when using the camera 20, the adjustment plate 9 is pushed to make the adjustment plate 9 push the protective plate 3 away from the support plate 1, and then the support plate 1 is flipped upward through the rotating rod 14 to make the camera 20 located on the upper side. The height of the camera 20 can be adjusted according to the needs of use to meet the use of the camera 20. At this time, the base 5, the extension plate 4 and the protective plate 3 support the support plate 1, and the side plate 2 protects the two sides of the camera 20. Among them, the side plate 2 is filled with an elastic layer 7, and the elastic layer 7 can be made of silicone, rubber and other materials, which can buffer the external force and improve the safety of the camera 20 when in use.
