[0050] Specifically, the dredging head 7 includes a connecting rod 702, a steel chain 701 and two ends 703; the two ends of the connecting rod 702 are respectively connected to one of the ends 703, and the two ends of the steel chain 701 are respectively connected to one of the ends 703. The steel chain 701 is connected by a plurality of buckles. This interlocking structure has a strong pulling force and a specific back-and-forth telescopic strength, and is also convenient to use when the space is small. The coil 2 includes a steel core 201 and an outer sheath layer 202 sleeved outside the steel core 201, so that the steel core 201 can move inside the outer sheath layer 202. In this embodiment, the steel core 201 is surrounded by multiple strands of steel wire, and the steel core 201 is protected by the outer sheath layer 202, which is not easy to break, and has good pipe bending characteristics, which is convenient for dredging and can also protect the hands. The motor 6 is connected to the claw plate 12 in a transmission manner, and the claw plate 12 is fixedly connected to the steel core 201 inside the coil 2, so that the motor 6 drives the steel core 201 inside the coil 2 to rotate through the claw plate 12. At this time, the steel chain 701 structure of the dredging head 7 powerfully impacts and stirs the large blockages in the pipeline, causing them to fall off to achieve the purpose of dredging the pipeline.

[0051] The dredging mechanism also includes a stopper 8, which is sleeved outside the coil 2 and is used to limit the movement range of the coil 2. The stopper 8 can prevent the coil 2 from winding and is not easy to be wired out or dropped.

Through such a setting, the limiter 8 has a unidirectional movement limiting effect on the coil 2.

[0053] Taking into account the up and down arrangement characteristics of the coil 2, in order to reduce stress when pulling out the coil 2 and increase the service life of the product and the convenience of use, the channel 803 in the main body 801 is a transition channel 803 with a height difference, and the outlet height of the channel 803 at the end of the channel 803 close to the motor 6 is higher than the outlet height of the channel 803 at the end close to the dredging head 7.

The self-locking switch button 902 can control the circuit to be always on, so that the motor 6 is always in a working state, which is convenient for continuous use and avoids premature stoppage caused by mispressing the start button 901. The debugger 9 can be directly operated manually, or the debugger 9 can be installed inside the pedal 10. The debugger 9 is detachably connected to the pedal 10 and can be taken out and controlled by the pedal 10, which is more convenient and labor-saving. The pedal 10 includes a surface shell 1001, a bottom shell 1002 and a crossbar 1003. The surface shell 1001 and the bottom shell 1002 are hinged, and the surface shell 1001 and the bottom shell 1002 are also connected by a spring. The crossbar 1003 is fixed on the surface shell 1001.

The start button 901 is pressed down through the cross bar 1003 to make the motor 6 work. The system panel group 13 is fixed on the main frame 1, and is provided with a power switch, a motor rotation direction switch and a motor speed display screen, which can adjust whether the motor 6 rotates clockwise or counterclockwise, thereby driving the steel core 201 in the coil 2 to rotate, and the speed of the motor 6 can be adjusted at the same time.
