The rotating disk is located on the outer side of the bottom surface of the fixed base, and a rotating handle is provided on its second side surface. By rotating the rotating handle, the rotating disk, the second rotating shaft and the second gear can be driven to rotate as a whole, so as to drive the first gear, the first rotating shaft and the lens to rotate as a whole, and adjust the lens angle.

6. The camera according to claim 1, characterized in that, The first locking mechanism includes: a fixing frame, a brake shaft, a compression spring, and a traction arm; wherein, The fixing bracket is set on the top side surface of the fixing base; The brake shaft passes through a first through hole on the top side surface of the fixed base along the height direction. Its first end is fixedly connected to the fixed frame, and its second end has a first conical surface that matches the second conical surface provided on the top side surface of the lens. The compression spring is sleeved on the outer surface of the brake shaft. Its first end is fixedly connected to the fixed frame, and its second end contacts and presses against the first side surface of the first end of the traction arm. The traction arm is movably mounted on the fixed frame, and the second side surface of its first end contacts and presses against the boss of the brake shaft; In the locked state, the compression spring applies downward pressure to the boss of the brake shaft through the traction arm, maintaining a first pressure between the first and second conical surfaces; in the released state, the second end of the traction arm is pressed down, and its first end pushes upward and compresses the compression spring, reducing the downward pressure on the boss of the brake shaft, maintaining a second pressure between the first and second conical surfaces.

7. The camera according to claim 2, characterized in that, The second locking mechanism includes: a brake block, a positioning spring, and a locking screw; wherein, The brake block includes a wedge-shaped component and a fixing part; wherein, the longitudinal section of the wedge-shaped component is a right trapezoid and the cross section is a rectangle, and its first end is fixedly connected to the fixing part; The first end of the positioning spring is fixedly connected to the positioning hole, and its second end extends out of the positioning hole to the upper cavity and is fixedly connected to the second end of the wedge-shaped piece.
