[0036] As Figures 1 - 10 shown, a new type of DIY quick-release fan blade includes a fan frame 1 and a fan blade 2. A fixing seat 3 is provided in the middle of the fan blade 2, and an elastic spiral locking component 4 is provided on the fixing seat 3. A limiting component 5 is provided in the middle of the fan frame 1. The limiting component 5 includes a bushing 51, a fixing block 52, a limiting block 53, a bearing 54 and a positioning ring 55. A limiting protrusion 531 is provided on the limiting block 53. The bushing 51 is fixed in the middle of the fan frame 1. The fixing block 52 is provided at one end of the bushing 51. The bearing 54 is fixed in the bushing 51. There is a gap for the limiting protrusion 531 to rotate between one end of the bearing 54 and the fixing block 52. A cavity 521 and at least one limiting groove 522 are formed in the fixing block 52. The number of the limiting protrusions 531 is the same as that of the limiting grooves 522. The limiting block 53 further includes an annular fixing portion 532. The limiting protrusions 531 are provided on the outer side of the annular fixing portion 532. Each limiting protrusion 531 is respectively movably connected with one of the limiting grooves 522. The annular fixing portion 532 is movably connected with the cavity 521. One end of the elastic spiral locking component 4 passes through the middle of the bearing 54 and is threadedly connected with the annular fixing portion 532. The positioning ring 55 is located on the side of the bearing 54 away from the fixing block 52. One end face of the positioning ring 55 fits with one end of the bearing 54, and the other end face is in the same plane as the end face of the bushing 51.

[0037] When assembling the fan blade 2 and the fan frame 1, align one end of the elastic spiral lock component 4 with the middle of the bearing 54 and insert it. After the above-mentioned end passes through the bearing 54, insert it into the annular fixing part 532. Rotate the elastic spiral lock component 4 to adjust the position of the limit protrusion 531. When the limit protrusion 531 corresponds to the limit groove 522, continue to apply a force in the direction of the fixed block 52 to the elastic spiral lock component 4, and snap the limit protrusion 531 into the limit groove 522. Then rotate in the opposite direction of the rotation of the fan blade 2, screw the end of the elastic spiral lock component 4 into the annular fixing part 532 for locking, release the fan blade 2, and the fan blade 2 is bounced away from the fixed block 52 by the elastic force of the elastic spiral lock component 4. The limit protrusion 531 is placed in the gap between the bearing 54 and the fixed block 52. When the fan blade 2 rotates, the limit protrusion 531 rotates in the above-mentioned gap. In order to prevent the end of the elastic spiral lock component 4 from not being able to align with the limit block 53 and the end of the annular fixing part 532 away from the bearing 54 from not being able to move out of the cavity 521 when installing the fan blade 2, during the rotation of the fan blade 2, the two end faces of the limit protrusion 531 are respectively in contact with and rotate with one end of the bearing 54 and the end face of the fixed block 52.

[0038] When disassembling the fan blade 2 and the fan frame 1, grasp the fan blade 2 and apply a force to the fan blade 2 in the direction of the fixed block 52. At the same time, adjust the position of the limit protrusion 531 until the limit protrusion 531 is completely placed in the limit groove 522. Then rotate the fan blade 2 in the direction of the rotation of the fan blade 2 until the end of the elastic spiral lock component 4 is loosened from the annular fixing part 532, and then the fan blade 2 can be removed. This solution adopts a fan blade spiral quick-release design, which can realize the quick replacement of the fan blade 2. At the same time, the bearing 54 is fixed in the bushing 51 by friction. When a relatively large force in the direction away from the bushing 51 is applied to the bearing 54, the bearing 54 can be removed, which is convenient for replacing the bearing 54.

[0039] Preferably, in an embodiment, as Figure 9 shown, the cavity 521 is composed of two parts, a wide part cavity and a narrow part cavity that communicate with each other. The wide part cavity and the narrow part cavity are respectively cylindrical cavities. The narrow part cavity is located on the side of the wide part cavity away from the bearing 54, and the limit groove 522 communicates with the wide part cavity. The annular fixing part 532 includes an annular wide part and an annular narrow part, which are integrally formed. The annular wide part is movably connected to the wide part cavity, and the annular narrow part is movably connected to the narrow part cavity.

[0040] Preferably, in an embodiment, as Figures 11 - 12As shown, the elastic spiral locking component 4 includes a fixing member 41, a support rod 42, a spiral lock 43 and a spring 44. One end of the support rod 42 is fixed to the middle of the fixing member 41, and the other end is connected to the spiral lock 43. An installation hole is formed in the middle of the fixing base 3, and one end of the fixing member 41 is fixed in the installation hole. The spiral lock 43 is threadedly connected to the annular fixing portion 532 of the limiting block 532. One end of the spring 44 is fixed in the gap between the fixing member 41 and the fixing base 3.

[0041] When assembling the fan blade 2 and the fan frame 1, grasp the fan blade 2, align the spiral lock 43 with the middle of the bearing 54, and apply a force to the fan blade 2 in the direction of the fixing block 52 until the end of the spiral lock 43 is inserted into the annular fixing portion 532. Then rotate the fan blade 2 to adjust the position of the limiting protrusion 531 until the limiting protrusion 531 corresponds to the limiting groove 522 of the fixing block 52. Continue to apply a force to the fan blade 2 in the direction of the fixing block 52 to snap the limiting protrusion 531 into the limiting groove 522. Then rotate in the opposite direction of the rotation of the fan blade 2 to screw the spiral lock 43 into the annular fixing portion 532 for locking. Release the fan blade 2, and the elastic force of the spring 44 will spring the fan blade 2 away from the fixing block 52.

[0042] When disassembling the fan blade 2 and the fan frame 1, grasp the fan blade 2 and apply a force to the fan blade 2 in the direction of the fixing block 52. At the same time, adjust the position of the limiting protrusion 531 until the limiting protrusion 531 is completely placed in the limiting groove 522. Then rotate the fan blade 2 in the direction of the rotation of the fan blade 2 until the end of the spiral lock 43 is disengaged from the annular fixing portion 532, and then the fan blade 2 can be removed.

[0043] Preferably, in the embodiment, as Figure 13 shown, the spring 44 is a conical wire compression spring 44. An annular protrusion 412 is provided on the outer side of the fixing member 41.
