For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] The following is a further description of the specific implementation of the utility model in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the utility model are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, but cannot be understood as limiting the utility model.

[0019] The preferred embodiment provided by the utility model is as follows: Figure 1 to Figure 4As shown, a wing assembly structure with switchable installation positions includes a fan disk 1, a leaf hairpin 2, and a wing 3; the fan disk 1 has an annular locking groove 11, and a plurality of locking columns 4 are arranged in the locking groove 11, and the locking columns 4 are evenly arranged along the locking groove 11; the fan disk 1 includes an inner ring 12 and an outer ring 13, and the inner ring 12 and the outer ring 13 are connected by reinforcing ribs 14. This design reduces the weight of the fan disk 1, reduces the production cost, and can ensure the tightness. The locking groove 11 is set on the outer ring 13, and the top of the locking groove 11 is open for the leaf hairpin 2 to connect, and the fan motor is locked to the inner ring 12 to drive the fan disk 1 to rotate.

[0020] The leaf hairpin 2 is an integrated structure, and the leaf hairpin 2 includes a first hairpin portion 21 and a second hairpin portion 22. A bending section 23 is provided between the first hairpin portion 21 and the second hairpin portion 22 to form a step between the first hairpin portion 21 and the second hairpin portion 22, so as to facilitate the connection and installation between the wing and the fan disk; the first hairpin portion 21 is connected to the locking column 4, and the wing 3 is connected to the second hairpin portion 22, so that the wing 3 is fixed to the fan disk 1 through the leaf hairpin 2. The leaf hairpin 2 is equipped with a locking member, and the locking member adopts a conventional screw. The locking member is used to connect the locking hole of the leaf hairpin 2. The first hairpin portion 21 is provided with a first locking hole 24, and the second hairpin portion 22 is provided with a second locking hole 25. The first locking column 41 is connected to the first locking hole 24 by a conventional screw, and the second locking hole 25 is connected to the wing 3 by a conventional screw; the arrangement of the first locking hole 24 corresponds to the position of the locking column 4; the second locking hole 25 is arranged linearly along the second hairpin portion 22.
