[0048] An output shaft 405 is rotatably connected to the inner wall of the second bracket 403. A second shaft support 404 is rotatably connected to the end of the output shaft 405. The end of the second shaft support 404 passes through the third housing 401 and is fixedly connected to it. A third bevel gear 406 is fixedly connected to the outer wall of both the output shaft 405 and the connecting shaft 402. The two third bevel gears 406 mesh with each other. A clamp 408 is fixedly connected to the end of the output shaft 405. The end of the clamp 408 extends to the outside of the third housing 401. A cutting tool 409 is installed on the inner wall of the clamp 408.

[0049] Working principle: The drive motor 103 drives the drive shaft 104 to rotate. The drive shaft 104 drives the fourth bevel gear 410 to rotate through the first bevel gear 105. The fourth bevel gear 410 drives the connecting shaft 402 to rotate. The connecting shaft 402 drives the output shaft 405 to rotate through the third bevel gear 406. The output shaft 405 drives the tool 409 to rotate through the clamp 408.

[0050] The first motor 107 drives the first worm gear 108 to rotate, the first worm gear 108 drives the first worm wheel 110 to rotate, the first worm wheel 110 drives the first bushing 106 to rotate, and the first bushing 106 drives the second housing 201 to rotate; the second motor 204 drives the second worm gear 205 to rotate, the second worm gear 205 drives the second worm wheel 207 to rotate, the second worm wheel 207 drives the second bushing 206 to rotate, and the second bushing 206 drives the third housing 401 to rotate, thereby enabling the tool 409 to rotate at multiple angles;

[0051] Before the second motor 204 drives the second worm gear 205 to rotate, the cylinder 217 pushes the rotating sleeve 218 to slide along the inner wall of the sliding hole 202. The rotating sleeve 218 drives the extension shaft 222 to move. The extension shaft 222 drives the sliding sleeve 214 to slide along the outer wall of the drive rod 211. At this time, the sliding sleeve 214 drives the slider 215 to slide along the inner wall of the groove 212 on the drive rod 211. When the extension shaft 222 moves, it drives the positioning wheel 219 to move, so that the slot 220 on the positioning wheel 219 disengages from the gear teeth on the first gear 210. At this time, it can ensure that the third housing 401 rotates normally.

[0052] When the second worm gear 205 rotates, it drives the drive rod 211 to rotate. The drive rod 211 drives the sliding sleeve 214 to rotate through the slider 215. The sliding sleeve 214 drives the extension shaft 222 to rotate synchronously through the second bevel gear 216. The extension shaft 222 drives the positioning wheel 219 to rotate synchronously, thus ensuring that the slot 220 on the positioning wheel 219 can always correspond to the gear teeth on the first gear 210. After rotation, the cylinder 217 pulls the extension shaft 222 to rotate in the opposite direction through the rotating sleeve 218. The extension shaft 222 drives the positioning wheel 219 to move in the opposite direction, so that the slot 220 on the positioning wheel 219 can accurately engage with the gear teeth on the first gear 210. Through the self-locking feature between the second bevel gears 216 and the engagement between the positioning wheel 219 and the first gear 210, the positioning of the third housing 401 is achieved.

[0053] When the third housing 401 rotates, the gear ring 208 drives the first gear 210 to rotate, the first gear 210 drives the third gear 304 to rotate, the third gear 304 drives the fourth gear 305 to rotate, and the fourth gear 305 drives the second shaft 302 to rotate, thereby driving multiple second gears 303 to rotate simultaneously, so that multiple second shafts 302 can rotate at the same time. Fan blades are installed at the ends of the second shafts 302. At this time, when the third housing 401 rotates, the airflow generated by the instantaneous rotation of the fan blades can blow away and clean the debris on the surface of the third housing 401.
