[0014] Both ends of the transmission flexible shaft are provided with connecting heads, and the conical drill bit is clamped on the connecting heads.

[0015] As a further description of the above technical solution:

[0016] A plurality of annular slices are arranged on the outer wall of the conical drill bit.

[0017] As a further description of the above technical solution:

[0018] The maximum outer diameter of the conical drill bit and the outer diameter of the annular spray head are both smaller than the outer diameter of the hose.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0020] In the utility model, a driver such as an electric drill is connected to one end of the transmission flexible shaft to drive the transmission flexible shaft to rotate, and a conical drill bit installed on the transmission flexible shaft rotates synchronously. The rotation of the conical drill bit impacts the scale on the condenser tube wall to make the scale fall off. The water supply pipe is connected to the high-pressure water pump so that high-pressure water is sprayed from the spray hole to impact the tube wall, and the stubborn scale is jetted to remove, thereby realizing the combination of mechanical impact and jet impact, and greatly improving the cleaning efficiency of the scale.
