[0030] The first mounting brackets 102 are located at the left and right ends of the threaded sleeve 107 , the limiting sleeves 109 are located at the front and rear ends of the threaded sleeve 107 , and the second connecting rod 105 is located at the upper end of the first connecting rod 104 .

[0031] The turning handle mechanism 2 includes a rotating disk 201, and a mounting groove 202 is provided at the upper end of the rotating disk 201. A fixed shaft 203 is fixedly connected to the inner wall of the mounting groove 202. A spring 204 is sleeved on the surface of the fixed shaft 203. A turning handle 205 is rotatably connected to the surface of the fixed shaft 203. An auxiliary groove 206 is provided at the upper end of the rotating disk 201. The spring 204 is used to bring the turning handle 205 back to the inside of the mounting groove 202 after use, thereby reducing the exposed external area of ​​the buckle, preventing scratches from the outside, and improving practicality.

[0032] The top end of the spring 204 is fixedly connected to the surface of the handle 205 , and the bottom end of the spring 204 is fixedly connected to the inner wall of the mounting groove 202 .

[0033] The supporting mechanism 3 includes a clamping plate 301, the lower end of the clamping plate 301 is fixedly connected to a threaded ring 302, the lower end of the threaded ring 302 is fixedly connected to a second mounting bracket 303, and the inner wall of the second mounting bracket 303 is rotatably connected to a second rotating shaft 304. The design of the clamping plate 301 and the threaded ring 302 provides connection and support for the overall parts, making the structure more stable.

The first connecting rod 105 is supported by the second connecting rod 105 and the threaded ring 302, and the first connecting rod 104 is supported by the second connecting rod 105 to be flat when the rotation reaches the limit. At this time, the lower end of the clamping disk 301 and the upper end of the reinforcing plate 106 clamp it. At this time, the turning handle 205 is released, and the turning handle 205 returns to the inside of the mounting groove 202 under the action of the spring 204, so as to reduce the volume of the leaked part. The turning handle 205 is used to drive the threaded rod 108 to rotate to drive the second connecting rod 105 and the first connecting rod 104 to change the angle to realize the design of fitting and clamping the automobile parts with the reinforcing plate 106 and the clamping disk 301, thereby achieving the purpose of more accurately clamping the automobile parts and more conveniently removing the parts when they need to be separated. It is more convenient to use and improves practicality.
