Description

Technical Field

[0001] The utility model relates to the technical field of camera brackets, and more specifically to a camera bracket which is easy to adjust. Background Art

[0002] When in use, the camera is sometimes installed on a bracket, and the bracket is used to fix the camera. Some camera brackets are provided with an angle adjustment device to adjust the pitch angle of the camera, but the angle adjustment device has a simple structure, generally only including a rotating shaft and a knob. The rotating shaft is driven to rotate by turning the knob, and then the camera is driven to rotate to adjust the pitch angle. However, after the adjustment is completed, it is not easy to fix the angle of the camera. Generally, it is only fixed by the static friction between the rotating shaft and the fixed frame. However, after long-term use, wear will occur at the friction point, resulting in a decrease in the static friction, causing the camera to rotate under the action of its own weight, and the camera cannot be fixed. In addition, a lifting device is generally provided on the camera bracket. The lifting device mostly adopts a screw-sleeve combination. By rotating the screw sleeve, the screw is driven up and down to complete the lifting. However, when lifting over a large range, it is necessary to rotate several circles of the screw sleeve, resulting in low adjustment efficiency. Utility Model Content

[0029] In this embodiment, when it is necessary to adjust the position of the lifting rod 4 over a large distance, the limit sleeve 6 is rotated until the first limit plate 20 and the second limit plate 21 are in contact. At this time, the limit block 11 corresponds to the first limit groove 7, and the lifting rod 4 is moved up and down until the limit block 11 corresponds to one of the second limit grooves 10.
