By setting up a disassembly and assembly structure 3, the movable column 308 is retracted into the movable groove 302. When aligned with the surface of the card block, it is released, so that the spring 304 pushes the second hexagonal card groove 309 to be sleeved on the surface of the card block.
[0026] In one embodiment, a blade plate 104 is fixedly sleeved on the surface of a plurality of rotating rods 103, and a plurality of holes and slots 106 are equidistantly arranged around one side of the fixed plate groove 1.
[0027] Specifically, such as Figure 5 As shown: the screw 204 is fixed by the slot 106, and the wind speed is adjusted by the angle of the blade 104, which serves to fix and adjust the wind speed.
[0028] In one embodiment, the rotating device 2 includes a transmission gear 201, a rotating ring 202 is installed at the center of one side of the transmission gear 201, a plurality of rotating gears 203 are meshed on the surface of the transmission gear 201, and a screw 204 is threadedly embedded on one side of the transmission gear 201.
[0029] Specifically, such as Figure 3 and 4 As shown: the rotation of the transmission gear 201 drives the rotation of the rotating gear 203 and the blade 104, and the transmission gear 201 is fixed by the screw 204, which plays the role of adjusting the angle of the blade 104.
[0030] In one embodiment, one end of the transmission gear 201 and the rotating ring 202 are fixedly sleeved on the surface of the connecting column 101 by bearings, one end of the center of one side of the plurality of rotating gears 203 is fixedly sleeved on the surface of the plurality of rotating rods 103, and one end of the screw 204 is threaded into the corresponding hole groove 106.
[0031] Specifically, such as Figure 3 and 4 As shown: The transmission gear 201, rotating ring 202, rotating gear 203 and screw 204 are fixed and limited by the connecting column 101, rotating rod 103 and hole groove 106, which plays the role of fixing and limiting.
[0032] In one embodiment, the disassembly structure 3 includes a fixed post 301, one end of which is provided with a movable groove 302. Four limiting blocks 303 are equidistantly mounted around the surface of the inner cavity of the movable groove 302. A spring 304 is installed at the center of one end of the inner cavity of the movable groove 302, and a limiting plate 305 is installed at one end of the spring 304.
[0033] Specifically, such as Figure 6 As shown: the spring 304 supports and pushes the limiting plate 305, thus providing support.
[0034] In one embodiment, four limiting grooves 306 are equidistantly arranged around the surface of the limiting plate 305, and a limiting post 307 is installed at the center of one side of the limiting plate 305.

[0037] Specifically, such as Figure 6 As shown: The fixing plate 105 fixes the fixing column 301, thus achieving the purpose of fixing.
[0038] Working principle: When disassembling, repairing, cleaning, or replacing the intermediate wind turbine structure used for cross-flow fan blades, tools are usually used to remove the screws on it and dismantle the structure connected to it before it can be taken out.
[0039] By having the worker hold the movable column 308 and squeeze the limiting column 307 along the direction of the limiting block 303 and the limiting groove 306, the spring 304 at the bottom of the limiting plate 305 is squeezed, aligning the opening of the first hexagonal slot 102 with one end of the card block inside the equipment and inserting it into the first hexagonal slot 102. Then, aligning the opening of the second hexagonal slot 309 with one end of the card block at the other end of the equipment, the worker releases the gripped movable column 308, and the spring force of the spring 304 pushes the movable column 308 out, and the inside of the second hexagonal slot 309 is fitted onto the surface of the card block at the other end of the equipment, making it convenient for disassembly, cleaning and replacement.
[0040] When adjusting the tilt angle of the blade 104, it is usually necessary to replace the impeller structure, resulting in a waste of the replaced impeller structure. By loosening the screw 204 and moving it out of the corresponding slot 106, and then holding the rotating ring 202 and rotating it, the transmission gear 201 is rotated, which in turn drives the rotating gear 203 and the rotating rod 103 to rotate, thereby adjusting the tilt angle of the blade 104 on the surface of the rotating rod 103. Then, the screw 204 is fixed in the corresponding slot 106. Adjusting the tilt angle of the blade 104 can adjust the airflow strength and wind speed.
