When adjusting, the external power supply starts the rotating motor 301. After starting, the rotating motor 301 drives the screw rod 303 to rotate. When the screw rod 303 rotates, through the cooperation with the nut sleeve 304, it drives the two connecting seats 308 to move, thereby driving the two rotating discs 302 to move and adjusting the distance between the two rotating discs 302. When the distance suitable for placing the pipe fitting 4 is adjusted, stop moving. At this time, place the pipe fitting 4 on the top of the two rotating discs 302.

[0021] The cleaning structure 7 includes an installation box 702, which is fixed to one side of the bottom end of the top of the support frame 5. A lead screw 7012 is installed inside the installation box 702, a lead screw sleeve 7013 is installed inside the lead screw 7012, a connecting plate 707 is fixed to the bottom end of the lead screw sleeve 7013, a spray head 704 is installed at one end of the connecting plate 707, a moving cavity 7010 is opened inside the spray head 704, a shielding block 7011 is installed inside the moving cavity 7010, extrusion rods 706 are installed on both sides of the connecting plate 707, a first spray hole 705 is opened on one side of one end of the spray head 704, a second spray hole 709 is opened on the other side of one end of the spray head 704, one end of the extrusion rod 706 penetrates through both sides of the spray head 704, and the connection between the extrusion rod 706 and both sides of the spray head 704 is in a sealed connection. A cavity 7014 is opened inside the top end of the support frame 5, a connecting pipe 703 is installed at the bottom end of the cavity 7014, and the bottom end of the connecting pipe 703 is connected to the top end of the spray head 704. A moving block 7015 is installed inside the bottom end of the water tank 6, connecting frames 701 are installed on both sides of the moving block 7015, and the connection between the connecting frames 701 and both sides of the bottom end of the water tank 6 forms a sealed connection. Extrusion frames 708 are fixed to both sides of one end of the connecting plate 707. An external thread is provided on the outer side of the lead screw 7012, an internal thread is provided on the inner side of the lead screw sleeve 7013, and a threaded connection is formed between the lead screw 7012 and the lead screw sleeve 7013. There are two groups of extrusion rods 706, and the two groups of extrusion rods 706 are symmetrically distributed on both sides of the shielding block 7011; Refer to Figures 7 - 12As shown: When the pipe fitting 4 is rotating, the cleaning liquid and clean water are injected into the interior of the water tank 6. There are two water storage chambers inside the water tank 6, so that the cleaning liquid and clean water are respectively injected into the two water storage chambers. Then, an external pressure pump pressurizes the interior of the water tank 6, and the internal pressure of the water tank 6 is monitored by the pressure sensor 10. When it is necessary to clean the surface of the pipe fitting 4, the valve on the connecting pipe 703 is opened. After opening, first, the cleaning liquid in one side water storage chamber inside the water tank 6 will flow into the interior of the cavity 7014, and then into the interior of the connecting pipe 703. The cleaning liquid inside the connecting pipe 703 will flow into the moving chamber 7010 inside the nozzle 704, and then be sprayed out through the first spray hole 705. At this time, the cleaning liquid sprayed out from the first spray hole 705 is on one side horizontal to the surface of the pipe fitting 4. When spraying horizontally, the water flow direction is parallel to the axis of the pipe fitting 4. Relying on the impact force and shear force of the water flow, surface impurities such as oil stains, debris, and scale are removed, and large contaminants are quickly peeled off in the primary washing stage. The water flow flushes along the tangential direction of the surface of the pipe fitting 4, forming a transverse circumferential flushing force. The relative movement between the water flow and the surface of the pipe fitting 4 generates a shearing effect, which can break the attachments between the impurities and the surface. When the first spray hole 705 is spraying water, the servo motor on one side of the lead screw 7012 is started to drive the lead screw 7012 to rotate. When the lead screw 7012 is rotating, through the cooperation with the lead screw sleeve 7013, it can drive the connecting plate 707 to move. When the connecting plate 707 is moving, it will drive the nozzle 704 to move to one side, so as to perform a cleaning operation on the surface of the support frame 5. When the nozzle 704 moves to one side of the pipe fitting 4, the extrusion rod 706 will touch one side of the fixed frame 9. As the nozzle 704 moves, the fixed frame 9 will squeeze the extrusion rod 706 to make the extrusion rod 706 move to one side. When the extrusion rod 706 moves to one side, it will push the blocking block 7011 to move to one side, blocking the first spray hole 705 and opening the second spray hole 709. And before the extrusion rod 706 squeezes the second spray hole 709, the extrusion frame 708 on one side of the connecting plate 707 will squeeze the connecting frame 701 to move to one side. When the connecting frame 701 moves to one side, it will drive the moving block 7015 to move to one side, thus blocking the water outlet hole for storing the cleaning liquid and opening the water outlet hole for storing clean water, so that the clean water flows into the interior of the nozzle 704 and is then sprayed out through the second spray hole 709. The spraying angle of the second spray hole 709 is 60°. At this time, the motor drives the nozzle 704 to move back. The 60° water spraying can increase the water flow coverage area by 30% - 50%, and uniformly clean the surface of the pipe fitting 4, washing away the fine impurities and cleaning liquid remaining on the surface of the pipe fitting 4. Thus, it realizes first using horizontal water spraying to remove stubborn stains, and then switching to 60° water spraying for overall flushing, taking into account both efficiency and cleanliness, without manual operation, improving the cleaning efficiency and saving labor costs. When the nozzle 704 moves to the original position, the same structural settings will make the blocking block 7011 and the moving block 7015 return to their original positions. By repeating the above operations several times, the cleaning effect on the surface of the pipe fitting 4 can be better.Clean more thoroughly. And when the pipe fitting 4 rotates, the brush on one side of the brush holder 803 will also brush the surface of the pipe fitting 4, further improving the cleaning effect and finally completing the cleaning work on the surface of the pipe fitting 4.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
