[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figures 1 to 5 As shown;

[0026] Combining the above:

[0027] In order to facilitate the positioning of the fan, the fan is produced with a clamping mechanism, including a positioning component 1;

[0028] The positioning assembly 1 includes a workbench 11 and four supporting legs 12 evenly fixedly connected to the bottom surface of the positioning assembly 1. A fixed shell 13 is provided below the workbench 11. A corrugated telescopic tube 14 is fixedly connected to the surface of the fixed shell 13. The top end of the corrugated telescopic tube 14 is fixedly connected to a first force block 17. One end of the first force block 17 inserted into the interior of the fixed shell 13 is fixedly connected to a sealing gasket. Two positioning tubes 15 are symmetrically fixedly connected to the surface of the fixed shell 13. One end of the positioning tube 15 is away from the fixed shell 13. A fixed tube 16 is fixedly connected, a sliding rod 18 is provided inside the positioning tube 15, the sliding rod 18 and the positioning tube 15 are slidably connected, one end of the sliding rod 18 is inserted into the fixed tube 16 and is fixedly connected to a first sealing block 19, a second force block 110 is provided inside the fixed tube 16, a positioning plate 111 is provided at the end of the fixed tube 16 away from the positioning tube 15, the second force block 110 and the positioning plate 111 are fixedly connected, and the end of the second force block 110 away from the positioning plate 111 is fixedly connected to a second sealing block 115.

[0029] In this embodiment, when the fan blades need to be fixed, the bellows 14 is pressed, compressing the bellows 14 and extending the first force block 17 toward the interior of the fixed housing 13. The liquid inside the fixed housing 13 applies force to the two slide bars 18. The slide bars 18 extend toward the interior of the fixed tube 16, squeezing the second sealing block 115. The second force block 110 moves the two positioning plates 111 toward each other, causing the four clamping plates 113 to fit against the surface of the fan blades. The connecting rod 112 rotates on the surface of the positioning shaft 114, ensuring that all the clamping plates 113 fit against the surface of the fan blades.

[0030] It should be noted that the clamping plate 113 is made of high-fiber synthetic plastic and has a certain degree of flexibility.

[0031] Going further:

[0032] In an optional embodiment, a spring 116 is sleeved on the surface of the second force-applying block 110 , and both ends of the spring 116 are fixedly connected to the second sealing block 115 and the fixing tube 16 , respectively.

[0033] In this embodiment, when the fan blade needs to be replaced, the force applied to the bellows expansion tube 14 is released, and the spring 116 will push the second sealing block 115 back due to its elastic potential energy, making it easier to clamp the next fan blade.

[0034] Going further:

[0035] In an optional embodiment, an anti-wear pad 117 is fixedly connected to the surface of the bellows expansion tube 14 .

[0036] In this embodiment, the anti-wear pad 117 protects the bellows telescopic tube 14 , reduces the friction of workers on the bellows telescopic tube 14 , and increases the service life of the bellows telescopic tube 14 .

[0037] Going further:

[0038] In an optional embodiment, the auxiliary component 2 is further provided inside the clamping plate 113;

[0039] The auxiliary component 2 includes a plurality of positioning rollers 21 disposed between two clamping plates 113 . Two bearings 22 are symmetrically provided at both ends of each positioning roller 21 . The positioning roller 21 is rotatably connected to the clamping plate 113 via the bearings 22 .

[0040] In this embodiment, when the fan blade is clamped and polished, the fan blade can be rotated by the positioning roller 21 to facilitate the polishing of the fan blade.

[0041] The working principle and usage process of the present invention are as follows: when the fan blades need to be fixed, the bellows telescopic tube 14 is pressed, the bellows telescopic tube 14 will be compressed, the first force block 17 will extend toward the inside of the fixed shell 13, and the liquid inside the fixed shell 13 will apply force to the two slide rods 18. The slide bar 18 will extend toward the inside of the fixed tube 16, the second sealing block 115 will be squeezed, the second force block 110 will make the two positioning plates 111 approach each other, the four clamping plates 113 will fit on the surface of the fan blade, and the connecting rod 112 will rotate on the surface of the positioning shaft 114 so that the clamping plates 113 can all fit on the surface of the fan blade. When the fan blade needs to be replaced, the force on the bellows 14 is released, and the spring 116 will push the second sealing block 115 back due to the elastic potential energy, which is convenient for clamping the next fan blade. The anti-wear pad 117 will protect the bellows 14, reduce the friction of the workers on the bellows 14, and increase the life of the bellows 14. When the fan blade is clamped and polished, the fan blade can be rotated by the positioning roller 21 to facilitate polishing of the fan blade.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
