[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] To achieve the above purpose, the technical solution of the utility model is as follows:

[0035] See also Figure 1-8 As shown, this embodiment provides a lens parameter adjustment device, such as a follow focus device, see Figure 1-4 , comprising: a body 1, a hand wheel 2, and a first quick-release assembly 3;

[0036] The body 1 serves as a first main body structure and includes a holding slot 11;

[0037] Handwheel 2 serves as the second main body mechanism;

[0038] The first quick-release assembly 3 includes a first clamping member 31 and a first triggering member 32. Both the first triggering member 32 and the first clamping member 31 are movably connected to the handwheel 2. The first triggering member 32 contacts the first clamping member 31. The first triggering member 32 can trigger the first clamping member 31 to engage or disengage the clamping member from the wall of the clamping slot 11.

[0039] In some embodiments, an expansion bracket 7 may also be included as a second main body structure.

[0040] In this embodiment, the body 1 and handwheel 2 of the follow focus device are two modules that usually need to be disassembled and assembled for flexible matching. During assembly, the user can move the first clamping member 31 by touching the first trigger member 32, so that the first clamping member 31 can enter the clamping slot 11. After releasing the first clamping member 31, it will engage with the groove wall of the clamping slot 11, ensuring the stability of the connection between the two. During disassembly, pressing the first trigger member 32 again allows the first clamping member 31 to move to release the engagement with the clamping slot, so that it can be removed from the clamping slot 11, facilitating rapid disassembly between the two. Compared with the existing technology, the cooperation between the first quick-release component 3 and the clamping slot 11 can achieve rapid disassembly between the body 1 and the handwheel 2, so that the body 1 and the handwheel 2 form two separate modules. During use, it is more convenient to carry, shoot, and replace, and it is more flexible to use, which greatly facilitates the user's work.

[0041] In another embodiment, the handwheel 2 serves as the first main body, and the body 1 serves as the second main body; a retaining slot 11 is provided on the handwheel 2; and a first retaining member 31 and a first trigger member 32 are movably mounted within the body 1. Compared to the previous embodiment, the positions of the first quick-release assembly 3 and retaining slot 11 can be interchanged.

[0042] In this embodiment, see Figure 3-4 In one implementation, the first trigger member 32 and the first holding member 31 can be designed as an integrated structure, and the two are fixed to ensure the stability of the structure; see Figure 7-8 In another implementation, the first trigger member 32 and the first holding member 31 can be set as a split structure and supported by an inclined surface.

[0043] In this embodiment, the handwheel 2 has a mounting cavity 5 therein and is further provided with a plurality of openings 4 communicating with the mounting cavity 5. The openings 4 include a first opening 41 and a second opening 42. One end of the first trigger member 32 is disposed within the handwheel 2, and the other end is exposed to the outside of the handwheel 2 through the first opening 41. One end of the first clamping member 31 is disposed within the handwheel 2, and the other end is exposed to the outside of the handwheel 2 through the second opening 42. This allows the first clamping member 31 to be moved by pressing the first trigger member 32, thereby achieving engagement or separation between the first clamping member 31 and the clamping slot 11. The above structural design allows the first quick-release assembly 3 to be disposed within the handwheel 2, making the overall structure more concise and more stable.

[0044] In this embodiment, the handwheel 2 further includes a mounting block 21 having a limiting slot 211 defined therein. A first trigger member 32 is slidably connected to the limiting slot 211, and an end of the first trigger member 32 distal from the first retaining member 31 extends through the limiting slot 211 to be exposed outside the handwheel 2. When the first trigger member 32 is pressed and moved, it is limited by the limiting slot 211 of the mounting block 21, preventing its position from shifting.

[0045] In this embodiment, the first holding member 31 includes a hook 311, and a notch 12 is provided on the groove wall of the holding groove 11, and the notch 12 can be regarded as a means for the hook 311 to enter and exit; when the first trigger member 32 can move relative to the mounting block 21, the hook 311 can move in and out of the notch 12, and when the hook 311 moves to the notch 12, the hook 311 can be removed from the notch 12; when the hook 311 moves to the holding groove 11, the hook 311 can be engaged with the holding groove 11; the first quick-release assembly 3 also includes a reset spring, which is arranged between the first holding member 31 and the mounting block 21, and is limited by the hole position set on the first holding member 31. When installing, one end of the first trigger member 32 extends out of the installation cavity 5 from the first opening 41, and the first trigger member 32 is pressed into the installation cavity 5 from the outside of the first opening 41, pushing the first holding member 31 to move in the installation cavity 5, and the hook 311 extends out of the installation cavity 5 from the second opening 42 and moves to the alignment notch 12, and the hook 311 enters the holding groove 11 from the notch 12, and releases the pressing force. The hook 311 will reset under the elastic force of the reset spring, and realize the engagement with the groove wall of the holding groove 11, and one end of the first trigger member 32 extends out of the installation cavity 5 from the first opening 41; when disassembling, press the first trigger member 32 again, and the hook 311 can slide from the holding groove 11 to the alignment notch 12, and the hook 311 can be removed from the notch 12, realizing quick disassembly between the hook 311 and the holding groove 11.

[0046] In this embodiment, a sliding limit surface 312 is provided on the inner side of the first clamping member 31, and a sliding limit boss 212 is provided on the mounting block 21; the sliding limit surface 312 includes a first sliding limit surface 3121 and a second sliding limit surface 3122, and the first sliding limit surface 3121 and the second sliding limit surface 3122 are respectively attached to and slidably connected with the side surface 2121 and the table 2122 of the sliding limit boss 212. The design of the above structure can ensure that the first clamping member 31 moves on a specific track and prevent its position from being offset. It is worth noting that the first clamping member 31 includes a hook 311, which can be attached to the table 2122 of the sliding limit boss 212 and protrude outside the table 2122, so that the hook 311 protruding outside the table 2122 can be connected to the groove wall of the clamping groove 11 during the installation process.

[0047] In this embodiment, two first retaining members 31 are provided, one on each side of the first trigger member 32, such that the two hooks 311 face away from each other on either side of the first trigger member 32. Two retaining slots 11 are provided, such that the hooks 311 are connected one-to-one with the retaining slots 11. During assembly, when the first trigger member 32 moves, it pushes the first retaining members 31 on both sides to move synchronously, causing the hooks 311 on both sides to move synchronously and snap into the two retaining slots 11 in the mounting slot 13, completing the assembly process. Similarly, during disassembly, the hooks 311 on both sides also move synchronously, moving from the two retaining slots 11 to the notch 12, completing the disassembly process.

[0048] In this embodiment, the two retaining slots 11 and the two first retaining members 31 are symmetrically arranged, allowing the hooks 311 of the two first retaining members 31 to switch between the two retaining slots 11. In actual use, due to different user habits, the way they hold the body 1 is uncertain. If only one retaining slot 11 were provided, the user would need to hold the body 1 at a specific angle and align the body 1 to facilitate assembly of the handwheel 2. However, with the above structure, by providing two symmetrical retaining slots 11 and two symmetrical first retaining members 31, the user does not need to align the body 1 to facilitate assembly, thereby achieving adaptability between the front and back installation of the handwheel 2 and the body 1. Furthermore, during use, the body 1 can be turned 180 degrees to carry it upside down, making it easier to use.

[0049] In this embodiment, the handwheel 2 also includes a handwheel body 22 and a bottom plate 23. The handwheel body 22 has a mounting cavity 5. The mounting block 21 is arranged in the mounting cavity 5 and is fixedly connected to the bottom plate 23. A mounting boss 231 is provided on the side of the bottom plate 23 away from the mounting block 21. The fuselage 1 is provided with a mounting groove 13, and the mounting boss 231 is accommodated in the mounting groove 13; the second opening 42 is provided on the side of the mounting boss 231, and the holding groove 11 is opened on the inner wall of the opposite sides of the mounting groove 13; when the fuselage 1 and the handwheel 2 are assembled, the first trigger member 32 is pressed to trigger the first When the locking member 31 is moved, the hook 311 is aligned with the notch 12. At this time, the mounting boss 231 can be aligned and locked into the mounting groove 13. The mounting boss 231 is limited by the mounting groove 13. After the first trigger member 32 is released, the return spring pushes the first trigger member 32 to move, triggering the hook 311 to move and be locked in the locking groove 11, so that the mounting boss 231 is locked in the mounting groove 13; similarly, when disassembling, the hook 311 is aligned with the notch 12 by moving the first trigger member 32, and the mounting boss 231 can be taken out of the mounting groove 13.

[0050] In this embodiment, the mounting boss 231 is provided with a terminal through-hole 232. The handwheel 2 also includes a first connector 24 and a circuit board 25.
