[0025] It should be noted that, in the present embodiment, when the anti-theft door is being welded, some welding points are located relatively offset. By starting one end of the transmission of the No. 2 drive motor 261, the fixed block 262 is driven to rotate, thereby controlling the adjustment angle of the limit plate 266. Then, when starting the No. 3 drive motor 263, the No. 2 drive rod 264 is driven to rotate by starting one end of the transmission of the No. 3 drive motor 263, so that the outer wall of the No. 2 drive rod 264 drives the gear 265 to rotate, and the outer wall of the gear 265 is used to rotate with the tooth block 272 on the top side of the fixed plate 271, thereby driving the fixed plate 271 to slide on the inner side of the limit plate 266 to adjust the position of the anti-theft door.

[0026] The outer wall of the second transmission rod 264 is fixedly sleeved with a gear 265, and the inner side of the sliding structure 26 is slidably connected with a fixed structure 27, and the fixed structure 27 includes a fixed plate 271, and a tooth block 272 is fixedly installed on one side of the top of the fixed plate 271 and on the inner side of the bottom of the sliding structure 26, and a telescopic groove 273 is opened at the top of the inner side of the fixed plate 271, and a threaded groove 2747 is opened at the top of the inner side of the telescopic groove 273, and a threaded rod 2741 is threadedly connected to the outer wall inside the threaded groove 2747, and a rotating handle 274 is fixedly installed at one end of the top of the threaded rod 2741.

[0027] It should be noted that, in the present embodiment, when the anti-theft door is welded and installed, the outer wall of the anti-theft door is inserted into the inner side of the fixed plate 271, and then the rotating handle 274 is rotated, and the outer wall of the rotating handle 274 and the threaded groove 2747 are used to rotate the thread, so that the threaded rod 2741 is lowered, and the extrusion plate 2746 is driven to push the movable spring 2745, thereby pushing the anti-slip pressure plate 2742 to press the four sides of the anti-theft door. The movable spring 2745 installed on the inner side of the buffer column 2748 can buffer when the anti-theft door is pressed, reducing the problem of damage to the surface of the anti-theft door during fixed installation. At the same time, the positioning rod 2743 is used to slide on the inner side of the positioning groove 2744 to limit the position.

[0028] The outer wall on the left side of the support frame 11 is provided with a discharge groove 14, and a discharge box 141 is fixedly installed on the inner side of the bottom of the discharge groove 14. The outer wall on the right side of the support frame 11 is provided with a water accumulation groove 15, and a water accumulation box 153 is fixedly installed on the inner side of the bottom of the water accumulation groove 15. A cleaning structure 6 is fixedly installed on the outer wall of one side of the sliding track 16, and the cleaning structure 6 includes a guide plate 65. A connecting frame 62 is fixedly installed on the top of the inner side of the discharge groove 14, and a No. 4 drive motor is fixedly installed on the outer wall of one side of the connecting frame 62. 61, one end of the transmission of the fourth driving motor 61 is connected to a rotating rod 63, the outer wall of the rotating rod 63 and the inner side of the top of the guide plate 65 are fixedly sleeved with a spiral brush 64, the bottom of the inner side of the water accumulation box 153 is fixedly installed with a water pump 151, the top of the water pump 151 is fixedly installed with a transmission water pipe 152, the cleaning structure 4 includes a cleaning column 41, the outer wall of the cleaning column 41 is fixedly installed with one end of the top of the transmission water pipe 152, and the outer wall of the top of the cleaning column 41 is fixedly installed with a nozzle 42.

[0029] It should be noted that, in this embodiment, the water sprayed by the cleaning structure 4 flows into the upper surface of the guide plate 65, and enters the inner side of the upper surface of the guide plate 65. At the same time, the polishing structure 5 collects the residue on the inner side of the upper surface of the guide plate 65 after passing the anti-theft door, and then starts the No. 4 drive motor 61, so that one end of the transmission of the No. 4 drive motor 61 drives the rotating rod 63 to rotate, so that the spiral brush 64 is driven by the rotating rod 63 to rotate, and the residue is brushed to the discharge box 141 inside the discharge trough 14, and the cleaned water flows into the water box 153 of the water trough 15 through the lower part of the right guide plate 65. The water flowing into the water box 153 starts the water pump 151 to transmit the water to the inside of the cleaning column 41 through the transmission water pipe 152, thereby realizing water circulation.

[0030] The working principle of the present invention is as follows: when the anti-theft door is welded and installed, the outer wall of the anti-theft door is inserted into the inner side of the fixing plate 271, and then the rotating handle 274 is rotated, and the outer wall of the rotating handle 274 and the threaded groove 2747 are used to rotate the threaded rod 2741, thereby driving the extrusion plate 2746 to push the movable spring 2745, thereby pushing the anti-slip pressure plate 2742 to press the four sides of the anti-theft door. The movable spring 2745 installed on the inner side of the buffer column 2748 can buffer when the anti-theft door is pressed, reducing the problem of damage to the surface of the anti-theft door during fixed installation. At the same time, the positioning rod 2743 is used to slide on the inner side of the positioning groove 2744 for limiting. By starting the No. 1 motor 21, one end of the No. 1 motor 21 drives the No. 1 transmission rod 23 inside the mobile frame 22 to rotate, and then the No. 1 transmission rod 23 drives the roller 24 on the outer wall to rotate, thereby driving the mobile frame 22 to slide on the upper surface of the slide track 16, and at the same time, the small filter 25 is used to assist during the sliding, so that the mobile frame 22 can slide on the upper surface of the slide track 16. The welding structure 3 is started to weld the surface of the anti-theft door where welding is needed, and the anti-theft door enters the lower surface of the guide port 131, and the fan 13 is started. The wind is transmitted to the guide port 131 through the fan 13 and enters the inner side of the dust shield 12 to dissipate heat on the surface of the anti-theft door. At the same time, water is sprayed on the surface of the anti-theft door through the cleaning structure 4 to cool it down and rinse the surface of the anti-theft door. Then, the polishing structure 5 is used to polish the welding points. When welding the anti-theft door, some welding points are located relatively offset. By starting one end of the transmission of the No. 2 drive motor 261 to drive the fixed block 262 to rotate, the adjustment angle of the limit plate 266 is controlled. Then, when starting the No. 3 drive motor 263, the No. 2 drive rod 264 is driven to rotate by one end of the transmission of the No. 3 drive motor 263, so that the outer wall of the No. 2 drive rod 264 drives the gear 265 to rotate, and the outer wall of the gear 265 and the tooth block 272 on the top side of the fixed plate 271 are used to rotate, thereby driving the fixed plate 271 to slide on the inner side of the limit plate 266 to adjust the position of the anti-theft door. The water sprayed by the cleaning structure 4 flows into the upper surface of the guide plate 65 and enters the inner side of the upper surface of the guide plate 65. At the same time, the polishing structure 5 collects the residue on the inner side of the upper surface of the guide plate 65 after passing the anti-theft door. Then, by starting the No. 4 driving motor 61, one end of the No. 4 driving motor 61 drives the rotating rod 63 to rotate, so that the spiral brush 64 is driven by the rotating rod 63 to rotate, and the residue is brushed to the discharge box 141 inside the discharge trough 14. The cleaned water flows into the water box 153 of the water trough 15 through the lower part of the right guide plate 65. The water flowing into the water box 153 starts the water pump 151 to transmit the water to the inside of the cleaning column 41 through the transmission water pipe 152, thereby realizing water circulation.
