[0022] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0023] Referring to Figures 1-6 As shown, a locking pin fixing device for a camera adapter ring to adapt a lens includes an adapter ring 10 and a lens locking device 20. The lens locking device 20 includes a baffle 201, a button 202, and a locking pin column 204. Through holes for screws to pass through are formed in both the upper and lower sides of the baffle 201, namely baffle holes 2011. The baffle 201 is fixedly connected to the surface of the adapter ring 10 through the baffle holes 2011 and screws. Through the tight fit of the screws and the baffle holes 2011, it is ensured that the baffle 201 is firmly fixed on the adapter ring 10, not easily loosened or detached, enhancing the stability and durability of the entire lens locking device. A button 202 is slidably connected between the baffle 201 and the adapter ring 10. A limiting groove 2025 is formed in the middle of the left side of the button 202. The design of the limiting groove 2025 of the button 202 enables the locking pin column 204 to accurately move inside it, realizing the functions of locking and releasing the lens. An auxiliary step 101 for the locking pin column is provided on the front side of the adapter ring 10. A locking pin column boosting spring 205 is fixedly connected to the position of the limiting groove 2025 at the front side of the auxiliary step 101 for the locking pin column. A locking pin column guiding block 2041 is fixedly connected to the front side of the locking pin column boosting spring 205, and the locking pin column guiding block 2041 is fixedly connected to the locking pin column 204. The locking pin column boosting spring 205 provides a stable restoring force for the locking pin column 204, ensuring that after the button 202 is released, the locking pin column 204 can quickly and accurately return to the locking position. The locking pin column guiding block 2041 guides the moving track of the locking pin column 204, ensuring the smooth movement and accurate positioning of the locking pin column 204. The locking pin column 204 is arranged inside the limiting groove 2025.

[0024] Furthermore, a button limiting hook 2024 is fixedly connected to the left end of the front side of the button 202, and a locking pin column fixing plane 2023 is provided between the front side of the button 202 and the left side of the button limiting hook 2024.

[0025] Furthermore, a button lifting inclined surface 2022 is formed on the left side of the button limiting hook 2024, and a button limiting plane 2021 is provided on the front side of the button limiting hook 2024. The design of the button lifting inclined surface 2022 enables the locking pin column 204 to smoothly contract when the button 202 is pushed leftward, while the button limiting plane 2021 ensures that the locking pin column guiding block 2041 can stay stably when reaching this position, preventing the locking pin column 204 from accidentally popping out.

[0026] Further, button assist springs 203 are fixedly connected to both the upper and lower sides of the left side of the button 202 and the limiting slot 2025. The other ends of the two button assist springs 203 are fixedly connected to the left side surface of the lock pin column auxiliary step 101. The button assist springs 203 provide sufficient elastic force for the button 202, enabling the user to feel an obvious feedback when releasing the button 202. At the same time, it also helps the button 202 to quickly reset to the initial position, improving the fluency and accuracy of the operation.

[0027] Further, a button limit 2012 is provided in the middle of the left side of the baffle 201. The button limit 2012 and the button limit hook 2024 are on the same horizontal plane. The button limit hook 2024 cooperates with the button limit 2012 on the baffle 201, effectively restricting the movement range of the button 202 and preventing it from being damaged or malfunctioning due to excessive movement.

[0028] Specifically, the outer sides of the two button limit hooks 2024 are respectively in contact with the upper and lower side surfaces of the button limit 2012.

[0029] Optionally, the inclination angle of the button lifting slope 2022 is from twenty degrees to thirty degrees.

[0030] Working principle: When the button 202 is pushed leftward, the lock pin column 204 uses the button lifting slope 2022 with the help of the edge slope of the lock pin column guide block 2041 to contract the lock pin column assist spring 205, thereby driving the lock pin column 204 to retract. And the lock pin column guide block 2041 reaches the button limit plane 2021, achieving the function of releasing the lens fixation. When the button 202 is released, the button assist spring 203 pushes the button 202 rightward until it reaches the button limit 2012 of the baffle 201 and engages with the button limit hook 2024 of the button 202 to achieve the limiting purpose. At this time, the lock pin column guide block 2041 returns to the position of the lock pin column fixing plane 2023 of the button 202 under the push of the lock pin column assist spring 205.
