The compression spring b3602 is used to control the position of the retainer b35. The release button 3603 is used to reset the compression spring b3602.

[0036] Working principle: When the device is working, the operator holds it on the outside of the handle 6 and presses the control button 2305 on the surface of the handle 6 to start the device to adjust automatically. The signal is sent to the battery 2303 via the connecting line b2304. The battery 2303 then provides power to the motor 2301 via the connecting line a2302. The motor 2301 drives the drive shaft 22 to rotate. The drive shaft 22 drives the two drive gears 25 to rotate. The rotation of the drive gears 25 drives the L-shaped sliding column 26 and the diameter-changing pusher 28 to move along the groove inside the slide 27. During the movement, the diameter-changing pusher 28 pushes the adjustment rod 29 on the surface to move around along the limiting groove 4, changing the outer length of the limiting groove 4. The cleaning distance of the brush bristles 5 fixed on the limiting groove 4 changes, and stops after reaching the inner diameter of the pipe, realizing adaptive pipe inner diameter, making it easy for the operator to clean pipes with different inner diameters.

[0037] After the device has been working for a long time, the outer bristles 5 will wear out. The operator can quickly replace the bristles 5 using the quick disassembly mechanism 3. The top of the inner protective shell 24 is fixed with a support column 31. The top of the support column 31 is connected to the connector 32. The limiting component 34 inside the connector 32 can fix the position of the inner protective shell 24. The compression spring a3401 pushes the limiting rod 3402 to lock between the retainer a33 and the retainer b35. When the operator presses the compression spring b3602, the retainer b35 connected to the compression spring b3602 moves downward and pushes the limiting rod 3402 back into the groove. The inner protective shell 24 can then be removed. After replacing it with a new shell, push the inner protective shell 24 to make the limiting rod 3402 lock back between the retainer a33 and the retainer b35. The separation button 3603 fixes the position of the retainer b35 through the connecting rod 3601, realizing the quick replacement of the bristles 5.
