A spring 27 is provided at one end of the clip 28, and the two ends of the spring 27 are respectively connected to the fixing shell 26 and one end of the clip 28 by welding. A docking shell 29 is provided on one side of the fixing shell 26, and the inner side of the docking shell 29 is connected to the bottom end of the fixing shell 26. The outer surface of the clip plate 23 is nested between the clip 28 and the fixing shell 26. Fixing screws 210 are provided on the docking shell 29 and the fixing shell 26. The fixing screws 210 pass through the docking shell 29 and are fixed to the fixing shell 26 by threaded rotation. A threaded rod 25 is provided in the fixing cover 22, and one end of the threaded rod 25 is connected to the fixing cover 22 by threaded rotation.

[0026] In this embodiment, when the staff uses the damping boring tool for installation and use, they can dock the connecting mechanism 2 with the tool head 21 on the connecting rod 12. In this way, the staff only needs to dock the fixing cover 22 with the snap plate 23 in the fixing shell 26 on the outer surface of the connecting rod 12 by snapping. Before the staff installs it on the fixing shell 26, they can insert the snap plate 23 into the snap device 28, and then the staff can dock the inner side of the docking shell 29 with the bottom end of the fixing shell 26 by snapping, and then rotate the fixing screw 210 to allow the fixing screw 210 to pass through the docking shell 29 and be fixed to the fixing shell 26 by threading, thereby improving its practicality in actual use.

[0031] like Figure 1-4 As shown, first, the connection mechanism 2 with the cutter head 21 is docked on the connecting rod 12. Then, the staff docks the fixed cover 22 with the snap plate 23 in the fixed shell 26 on the outer surface of the connecting rod 12 by snapping, and installs it in front of the fixed shell 26. Next, the staff inserts the snap plate 23 into the snap device 28, and then snaps the inner side of the docking shell 29 to the bottom end of the fixed shell 26. Subsequently, by rotating the fixing screw 210, the fixing screw 210 is fixed to the fixed shell 26 by threading through the docking shell 29. In order to ensure that the threaded rod 25 in the fixing cover 22 can be stably fixed in the connecting rod 12, the snap mechanism 3 is used in the connecting rod 12 to snap and fix it. The staff only needs to rotate the threaded rod 25 to dock it in the fixing cover 22, and then nest the threaded rod 25 in the connecting rod 12 to allow the snap beads 32 in the snap mechanism 3 to snap on the outer surface of the threaded rod 25. These steps further improve the practicability of the damping boring tool in actual use.
