[0026] The focus tracking toothed belt 201 is a belt with a toothed structure for meshing with the zoom ring of the lens. When the toothed belt moves, it drives the zoom ring of the lens to rotate, thereby changing the focal length of the lens.

[0027] The protrusion structure inside the adjusting member 202 is used for the tension of the focus tracking toothed belt 201 to ensure the close contact between the focus tracking toothed belt 201 and the lens zoom ring, and to avoid slipping or instability during the zooming process.

[0028] The focus tracking motor 3 is a key part of the drive system. It is a small but powerful motor that can provide precise torque and speed control. The focus tracking motor 3 meshes with the focus tracking toothed belt 201. By rotating the focus tracking motor 3, the focus tracking toothed belt 201 is driven, and then the zoom operation of the lens is controlled.

[0029] The catheter body 7 provides an installation position for the focus tracking motor 3 and also plays a role in guiding and supporting to ensure the stability and positioning accuracy of the focus tracking motor 3 during operation.

[0030] An installation part 5 is detachably installed on the camera body 1. The installation part 5 includes: a first installation member 501; a first fastening member 503 rotatably installed on the first installation member 501.

[0039] The second fastener 406 is a rotatable component, such as a knob or a screw, etc., used to adjust and fix the position of the conduit body 7. By rotating the second fastener 406, the clamping force on the conduit body 7 can be adjusted to ensure that these components will not loosen due to vibration or movement during shooting.

[0040] The catheter clamp 4 further includes: a rotating handle 402, which is installed on the connecting member 403, and a placement groove for cooperating with the rotating handle 402 is provided on the second mounting member 401.

[0041] The rotating handle 402 is an operation part that is easy to grip and is installed on the connecting member 403. Users can adjust the position or tightening degree of the connecting member 403 by rotating the rotating handle 402, thereby indirectly adjusting the fixing force of the catheter clamp 4 on the catheter body 7.

[0042] The placement groove is used to cooperate with the use of the rotating handle 402 to prevent the rotating handle 402 from rotating by itself when not needed, ensuring the stability of the catheter body 7 during the shooting process.

[0043] The third mounting member 6 is provided on the camera body 1. The third mounting member 6 includes a fixed plate and a moving plate, and the fixed plate and the moving plate are connected by a limiting member.

[0044] The fixed plate is the basic part of the third mounting member 6 and is directly fixed on the camera body 1, providing a stable support for the entire mounting system and ensuring the stability of the additional accessories during the shooting process. The moving plate is relatively independent of the fixed plate but is connected to it by a limiting member and can move within a certain range, allowing users to adjust the position of the moving plate according to needs to adapt to accessories of different sizes or shapes, increasing the versatility and flexibility of the mounting member. The limiting member is used to connect the fixed plate and the moving plate and at the same time limit the movement range of the moving plate to prevent instability or damage caused by excessive movement, enabling the camera body 1 to be mounted on tripods of different sizes.

[0045] The catheter body 7 is placed in the placement hole 404.

[0046] Placing the catheter body 7 in the placement hole 404 can ensure its precise position inside the device and avoid displacement due to vibration or movement during use.
