As the rotating disk 402 rotates further, the blocking rod 404 can no longer rotate further, which will cause the spring 406 to be stretched until the trigger block 405 contacts the touch switch 407 in the installation port 403, which can prompt the driving motor 401 to stop driving the rotating disk 402 to rotate, so that the clamping rod 306 applies appropriate clamping force to the flange, which can ensure that the flange is stably clamped while avoiding damage to the flange caused by excessive clamping force, and the use effect is better.
