A groove 306 is provided on the side of the fixing ear 302 away from the upper housing 2 to cooperate with the T-shaped fixing strip 305. The side of the T-shaped fixing strip 305 close to the inner wall of the groove 306 contacts the inner wall of the groove 306.

[0028] In this embodiment: by setting up a main body 1, an upper shell 2, a fixing component 3, a rotating wheel 4, and a rotating blade 5, during use, the upper shell 2 and the main body 1 can be connected and fixed by the fixing component 3, and the fixing method is relatively simple, which makes it convenient to open the upper shell 2 later to repair the internal parts of the main body 1, bringing convenience to the staff. By setting up the installation component 6, the rotating blade 5 and the rotating wheel 4 can be connected, installed, and fixed, and the installation method is relatively convenient, which makes it convenient to disassemble, repair, or replace the rotating blade 5 later.

[0029] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, the mounting component 6 includes a positioning block 601 and a plug-in block 602. The positioning block 601 is fixedly connected to the rotating wheel 4 on the side near the rotating wheel 4, and the plug-in block 602 is fixedly connected to the rotating blade 5 on the side near the rotating blade 5. A plug-in groove 603 is provided on the side of the positioning block 601 away from the rotating wheel 4 to cooperate with the plug-in block 602. The side of the plug-in block 602 near the inner wall of the plug-in groove 603 contacts the inner wall of the plug-in groove 603.

[0030] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, a fixing pin 604 is provided on the rear side of the positioning block 601. The front side of the fixing pin 604 passes through the positioning block 601 and the plug block 602 in sequence and extends to the front side of the positioning block 601. A locking nut 605 is threadedly connected to the front side of the surface of the fixing pin 604.

[0031] Specifically, such as Figure 5 As shown, the positioning block 601 has through holes 606 on its front and rear sides for use with the fixing pin 604, and the insertion block 602 has through holes 607 on its rear side for use with the fixing pin 604. The surface of the fixing pin 604 is slidably connected to the inner walls of the through holes 606 and through holes 607 on the side closest to the inner walls of the through holes 606 and through holes 607, respectively.

[0032] In this embodiment, by setting a positioning block 601, a plug-in block 602, a plug-in groove 603, a fixing pin 604, a locking nut 605, a through opening 606, and a through hole 607, when installing the rotating blade 5, the rotating blade 5 is installed by inserting the plug-in block 602 into the plug-in groove 603 of the positioning block 601, then passing the fixing pin 604 through the through opening 606 of the positioning block 601 and the through hole 607 of the plug-in block 602 in sequence, and then locking the fixing pin 604 with the locking nut 605. The installation of the rotating blade 5 is thus completed. The operation is relatively simple, which facilitates the disassembly, maintenance, or replacement of the rotating blade 5 in the future.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a reinforcing plate 7 is fixedly connected to the bottom of the support block 301 on the side away from the main body 1, and the side of the reinforcing plate 7 close to the main body 1 is fixedly connected to the main body 1.

[0034] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, rubber pads 8 are fixedly connected to both sides of the bottom of the T-shaped fixing strip 305, and the side of the rubber pad 8 closest to the fixing ear 302 is in close contact with the fixing ear 302.

[0035] In this embodiment: by setting the reinforcing plate 7, the support stability of the support block 301 on the miniature air rod 303 can be improved. By setting the rubber pad 8, the downward pressure can be buffered when the T-shaped fixing strip 305 is pressed down, preventing the T-shaped fixing strip 305 from colliding with the fixing ear 302, and increasing the friction between the T-shaped fixing strip 305 and the fixing ear 302.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a mounting base 9 is fixedly connected to the bottom of the main body 1. Mounting holes 10 are provided around the top of the mounting base 9. The number of mounting holes 10 is several.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, a sealing gasket 11 is fixedly connected around the bottom of the upper housing 2, and the side of the sealing gasket 11 closest to the main body 1 is in close contact with the main body 1.

[0038] In this embodiment: by setting the mounting base 9 and the mounting hole 10, the main body 1 can be easily installed and fixed with other supporting components. By setting the sealing gasket 11, the connection between the upper shell 2 and the main body 1 can be sealed to prevent water leakage.

[0039] Working principle: In use, the upper housing 2 is closed, and then the T-shaped fixing strip 305 is rotated so that it rotates into the groove 306 of the fixing ear 302 via the rotating shaft. Then, the miniature air rod 303 is activated to retract, causing the output rod of the miniature air rod 303 to move the connecting plate 304 downward. The connecting plate 304, via the rotating shaft, moves the T-shaped fixing strip 305 downward, pressing and securing the top of the fixing ear 302, thus fixing the upper housing 2. The operation is reversed to release the fixation of the upper housing 2. The operation is convenient and easy to use. The upper housing 2 can be opened later to repair the internal parts of the main body 1, which brings convenience to the staff. When installing the blade 5, the blade 5 is inserted into the insertion groove 603 of the positioning block 601 using the insertion block 602, and then the fixing pin 604 is passed through the through hole 606 of the positioning block 601 and the through hole 607 of the insertion block 602 in sequence. Then the fixing pin 604 is locked with the locking nut 605, and the installation of the blade 5 can be completed. The blade 5 can be disassembled by reversing the operation. The operation is relatively simple, which facilitates the disassembly, repair or replacement of the blade 5 in the later stage.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
