Radiator fan fixing buckle device and its assembly structure

A radiator fan fixing buckle device, comprising a first buckle and a second buckle, wherein:

• said first buckle comprises a first vertical strip and two first horizontal strips formed by bending a metal strip, said first horizontal strips each having a fixed end and an opposing free end, said first vertical strip comprising a latching protrusion bent at the middle thereof, the direction of said protrusion being selectively opposite to or the same as the direction of the free ends of said first horizontal strips, the fixed ends of said two first horizontal strips being respectively connected to opposing upper and lower ends of the said first vertical strip, the free ends of said two first horizontal strips being respectively bent to form a first buckling portion, said first buckling portion extending in the direction of said first vertical strip;
• said second comprises a second vertical strip and two second horizontal strips formed by bending a metal strip, said second horizontal strips each having a fixed end and an opposing free end, said second vertical strips being parallel to said first vertical strip, the fixed ends of said two second horizontal strips being respectively bent into a U-shape to form a hook portion, the said hook portions of said two second horizontal strips having a respective hook tip thereof respectively connected to opposing upper and lower ends of said second vertical strip, the free ends of said two second horizontal strips being respectively bent to form a second buckling portion, said second buckling portion extending in the direction of said second vertical strip;
• and
• said buckling portions of said two first horizontal strips of said first buckle and said second buckling portions of said two second horizontal strips of said second buckle are respectively used to enable said first vertical strip of said first buckle to be hooked by said hook portions of said second buckle, and said latching protrusion of said first buckle to be latched on an inner side of said second vertical strip after being respectively embedded in a radiator fan.
