The conical groove 2802 is located at the end of the drill body 28 away from the drill bit connector. Specifically, the spiral groove 2801 is used to form a suitable cutting edge space on the one hand, which is beneficial to the cutting of the workpiece to be cut, and on the other hand, to form a chip removal channel, which is beneficial to the discharge of cutting chips when drilling the workpiece to be cut. The tapered groove 2802 not only facilitates the feeding of the drill body 28 , so that there is a greater force when the drill body 28 contacts the workpiece to be cut, but also increases the wear resistance of the drill body 28 and reduces the probability of the drill body 28 being worn out.

The drilling structure 100 of the cutting head of this embodiment further includes a damper (not shown in the figure), the damper is arranged on the drilling cylinder 27, and the damper can adjust the length direction of the sleeve and the drill bit assembly along the intermediate connecting piece movement speed. When drilling, when the distance between the drill body 28 and the part to be cut is large, the drill body 28 moves towards the part to be cut at a faster speed, and the distance between the drill body 28 and the part to be cut gradually decreases. The moving speed of the body 28 is too fast, so that the drill body 28 is skewed relative to the part to be cut, and the damper can reduce the moving speed of the drill bit assembly driven by the sleeve.

In addition, the damper can also play the role of shock absorption and energy dissipation, so as to ensure that the drill body 28 is stably positioned at the position to be drilled. After the drilling is completed, the sleeve drives the bit body 28 to move away from the part to be cut at a slower speed first, and then move away from the part to be cut at a faster speed under the damping effect of the damper, so as to realize the correctness of the drill. The quick separation of the drill bit body 28 from the to-be-cut part shortens the time for drilling the to-be-cut part by the drilling structure 100 of the cutting head, and realizes rapid drilling of the to-be-cut part.
