The air inlet hole 12 is communicated with the heat dissipation pipe 40. An air inlet component 30 is also rotatably arranged on the outer wall of the connecting part 10. The position of the air inlet component 30 matches that of the air inlet hole 12. The air inlet component 30 guides the cooling fluid to enter the heat dissipation pipe 40 through the air inlet hole 12.

[0029] In this embodiment, when drilling, an air intake assembly 30 is installed on the outer wall of the connecting portion 10 so that the position of the air intake assembly 30 matches the position of the air intake hole 12, and a device (such as an air compressor) providing cooling fluid is installed. Then, the connecting portion 10 is driven by a driving motor to rotate, thereby driving the drilling portion 20 to rotate and drill holes, and the cooling fluid enters the air intake assembly 30, and the air intake assembly 30 guides the cooling fluid through the air intake hole 12 into the heat dissipation pipe 40, and the heat dissipation pipe 40 transports the cooling fluid to the drilling area for heat dissipation treatment;

[0030] Through the coordination among the air intake assembly 30, the air intake hole 12 and the heat dissipation pipe 40, the drilling portion 20 can be effectively cooled during the drilling process of the drilling portion 20 to avoid high temperature affecting the drilling efficiency. At the same time, the flowing cooling fluid can also facilitate the discharge of the debris in the drilled hole along the chip groove of the drilling portion 20, thereby improving the drilling efficiency and greatly improving the overall practicality.

[0031] Specifically, the air inlet holes 12 are provided in a plurality of groups, and the plurality of air inlet holes 12 are arranged on the connecting portion 10 in a ring array.

[0032] In this embodiment, the multiple groups of air inlet holes 12 can facilitate the cooling fluid to enter the heat dissipation pipe 40 .

[0039] Specifically, a connecting flange 34 is provided on the connecting pipe 33 , and the connecting flange 34 is fixedly connected to the connecting pipe 33 .

[0040] In this embodiment, the connection flange 34 is provided to facilitate connection processing, so that the cooling fluid can stably enter the heat dissipation pipe 40.

[0041] Specifically, two groups of limiting plates 11 are symmetrically arranged on the outer wall of the connecting portion 10 , and the first shell 32 and the second shell 36 are rotatably arranged between the two limiting plates 11 .

[0042] In this embodiment, the limiting plate 11 can facilitate the positioning of the air intake assembly 30 to avoid misalignment between the air intake assembly 30 and the air intake hole 12, thereby preventing the normal heat dissipation process from being affected.
