The angle adjusting mechanism 4 comprises a first gear 401 fixedly arranged on the surface of the rotating rod 306. The inside of the mounting frame 305 is hingedly connected with a first toothed plate 402 engaged with the first gear 401. T-shaped grooves 403 are formed at the top and bottom of the inside of the first toothed plate 402. A T-shaped block 404 is slidably arranged in the inside of the T-shaped groove 403. An inclined groove 405 is formed in the inside of the T-shaped block 404. An extrusion plate 406 matched with the inclined groove 405 is slidably arranged in the inside of the first toothed plate 402. Limiting sleeves 407 are fixedly connected to the top and bottom of one side of the inside of the mounting frame 305. Limiting plug blocks 408 matched with the narrow mouths of the T-shaped grooves 403 are slidably connected in the inside of the limiting sleeves 407. Reset springs 409 are fixedly connected between the limiting plug blocks 408 and the limiting sleeves 407. Resistance plates 410 matched with the extrusion plate 406 are fixedly connected between the two sides of the inside of the mounting shell 1, and two resistance plates 410 are symmetrically arranged above and below.

[0022] As a preferred embodiment, in order to facilitate the accelerated flow of air around the heat dissipation fins 2, a multi-angle blowing mechanism 5 is arranged on the top of the mounting shell 1. The multi-angle blowing mechanism 5 comprises two U-shaped frames 501 fixedly arranged on the two sides of the top of the mounting shell 1. Short rods 502 are rotatably arranged on the front side and the rear side of the inside of the U-shaped frame 501. An electric fan 503 is fixedly connected between the two short rods 502. One end of the front short rod 502 extends to the outside of the U-shaped frame 501. A second gear 504 is fixedly connected to the surface of the front short rod 502. A cam 505 is fixedly connected to the surface of the reciprocating lead screw 302. A second toothed plate 506 engaged with the second gear 504 is slidably arranged on the top of the mounting shell 1. A hollow strip frame 507 matched with the cam 505 is fixedly connected to one side of the second toothed plate 506. A plurality of limiting sliding grooves 10 are equidistantly formed on the front side of the mounting shell 1. Limiting sliding blocks 11 are slidably connected in the inside of the limiting sliding grooves 10, and the limiting sliding blocks 11 are fixedly connected with the front side of the second toothed plate 506 through supports.

[0023] During heat dissipation: the electric fan 503 and the drive motor 301 are started. The electric fan 503 accelerates the flow of air around the heat dissipation fins 2. When the drive motor 301 is started, the drive motor 301 drives the reciprocating screw 302 to rotate. The reciprocating screw 302 drives the cam 505 to reciprocate and laterally squeeze the hollow bar frame 507, prompting the hollow bar frame 507 to drive the second tooth plate 506 to reciprocate and mesh with the second gear 504. The second gear 504 reciprocates to adjust the blowing direction of the electric fan 503 through the short rod 502. When the reciprocating screw 302 rotates, the threaded sleeve 303 on the surface of the reciprocating screw 302 will drive the cross plate 304, the mounting frame 305, the rotating rod 306 and the scraper 307 to move downward. The scraper 307 descends to clean the dust attached to the side of the guide groove 7. As the mounting frame 305 descends, the extrusion plate 406 at the bottom of the mounting frame 305 will be pressed and contacted with the bottom stop plate 410 in advance, prompting the extrusion plate 406 to squeeze and push the T-block 404 through the inclined surface of the inclined groove 405. The T-block 404 is forced to squeeze the limiting plug 408 out of the T-slot 40 3, as the T-block 404 fills the narrow inside of the T-slot 403, the extrusion plate 406 is forced to drive the first tooth plate 402 to rise through the T-block 404 until the top limit plug 408 is limited and matched with the T-slot 403. When the first tooth plate 402 rises, it will engage with the first tooth plate 402, prompting the rotating rod 306 to drive the scraper 307 to tilt. As the scraper 307 adjusts its tilt, the corresponding threaded sleeve 303 will change from the downward thread path of the reciprocating screw 302 to the upward path, thereby driving the scraper 307 in the tilted state to rise; When the threaded sleeve 303 rises to the limit of the ascending path of the reciprocating screw 302, the corresponding scraper 307 is squeezed and matched by the top extrusion plate 406, the inclined groove 405, the T-block 404 and the support plate 410, so that the scraper 307 forms a balanced state before descending.
