[0014] This utility model has the following beneficial effects:
[0015] 1.

[0026] Specifically, the tool holder 1 is used to fix the first rotating ring 11, the first rotating ring 11 is used to slide the rotating rod 13, the rotating rod 13 is used to drive the second rotating ring 12 to rotate, the second rotating ring 12 is used to drive the first rotating shaft 14 to rotate, the first rotating shaft 14 is used to drive the damping plate 15 to rotate, and the second rotating shaft 16 is used to drive the damping plate 15 to rotate.
[0027] Reference Figure 2 and Figure 3 The outer wall of the second rotating ring 12 is fixedly connected to a fixing post 17, the outer wall of the fixing post 17 is fixedly connected to a second spring 18, the lower outer wall of the second spring 18 is provided with a connecting post 19, the outer wall of the connecting post 19 is fixedly connected to the inner wall of the tool holder 1, and the outer wall of the spring post 8 is slidably connected to the inside of the outer shell 7.

[0029] Working principle: When the device is needed, firstly, rotate the rotating plate 9 to retract the spring column 8, inserting the support rod 4 into the inside of the handle 1 to compress the first spring 2, causing its sliding block 6 to engage with the outer wall of the right retaining ring 3. When the reamer body 10 needs to extend or retract, rotate the rotating plate 9. As the rotating plate 9 rotates, it causes the spring column 8 to retract. When the spring column 8 extends or retracts, it causes the sliding block 6 to slide inside the outer shell 7. When the first spring 2 slides away from the outer wall of the right retaining ring 3, it extends. Simultaneously, the sliding block 6, under the action of the spring column 8, slides back into the inside of the handle 1. When the first spring 2 extends, it causes the support rod 4 to slide. When the support rod 4 slides, it causes the left retaining ring 3 to engage with the outer wall of the sliding block 6. This device allows for the adjustment of the clamping length of the reamer body 10, preventing excessive extension and thus reducing the quality of the reaming hole. When the reamer body 10 vibrates excessively, it pushes the rotating rod 13, which in turn drives the second spring 18 to hook the connecting post 19, causing the second spring 18 to extend. When the second spring 18 extends, it drives the fixed post 17 to rotate. When the fixed post 17 rotates, it drives the first rotating shaft 14 to rotate. When the first rotating shaft 14 rotates, it drives the damping plate 15 to rotate. When the damping plate 15 rotates, it clamps the reamer body 10, thereby reducing the impact force during vibration and decreasing the load and wear on the tool. Using this device not only maintains the stability of the tool but also improves the surface quality of the reamed hole.
