In this embodiment, each of the first connecting portion and the second connecting portion includes two limiting convex strips 151 spaced apart from each other; a distance between the two limiting convex strips 151 matches a width of each limiting sheet 910; and the limiting sheets 910 are inserted along gaps between the two limiting convex strips 151 to cause the free ends of the limiting blocks 150 to be inserted into the limiting slots 901 along the insertion ports 912. By the arrangement of the above structure, the two limiting convex strips 151 that are spaced apart from each other form a mounting track, and the limiting sheets 910 are inserted along the gap between the two limiting convex strips 151, thereby defining a translation direction of the first fan 100 and/or the second fan 200 relative to the connector. This allows the free ends of the limiting blocks 150 to be inserted along the insertion ports 912, thereby facilitating the user to assemble the product.
In this embodiment, the combined fan further includes a connector housing 12a; insertion notches are provided in two sides of the connector housing 12a; the connector is connected to the connector housing 12a and at least partially located in the insertion notches; and the first fan 100 and the second fan 200 are inserted along the insertion notches and connected to the connector. By the arrangement of the above structure, an edge of the connector housing 12a can effectively protect the connector, the first fan 100, and the second fan 200, improve the stability of the product, prevent breakage from a joint, make the product firmer and more durable.
In this embodiment, the first fan 100 and/or the second fan 200 is provided with a rope hole 160; and the rope hole 160 is configured to allow a rope to pass through. By the arrangement of the above structure, during use, a hanging rope or a connecting ring can be threaded through the rope hole 160 to form a hanging component, which is convenient for the user to hang the product.
