[0018] The utility model is further described below in conjunction with the accompanying drawings.
[0019] According to the attached Figures 1 to 5 As shown, the detachable combined fan blade of the utility model comprises a hub 1 connected to the output shaft of the motor and a plurality of fan blades 2 rotating with the hub 1. The outer edge of the hub 1 is provided with a plurality of guide connection blocks 3, each of which is provided with a guide groove 31, and the side wall of the hub 1 is provided with a buckle hole 11 communicating with the guide groove 31. The end of the fan blade 2 is provided with a buckle block 4 for buckling on the hub 1, and the fan blade 2 slides inward along the guide groove 31 while the buckle block 4 is buckled on the buckle hole 11.
[0020] In this way, through the structural cooperation of the guide connecting block 3 and its guide groove 31 and the snap block 4 and the snap-on hole 11, several fan blades 2 can be separated from the wheel hub 1, so that the various parts of the fan blades can be disassembled, packaged and transported, thereby reducing the cost of packaging and transportation; when in use, it is only necessary to slide each fan blade 2 along the guide groove 31, and snap the snap block 4 onto the snap-on hole 11, and snap each fan blade 2 onto the wheel hub 1, so that the structure is stable and the normal use of the product is ensured.
[0021] Reference Figures 1 to 5 As shown, in further detail, the guide groove 31 is provided on the outer side of the guide connection block 3 , and the buckle block 4 slides along the guide groove 31 and buckles on the buckle hole 11 .
[0022] The guide connecting block 3 of the present structure ensures that the fan blade 2 slides smoothly into the guide groove 31 and that the buckle block 4 is firmly buckled on the buckle hole 11, thereby ensuring that each fan blade is firmly buckled on the hub 1, thereby enhancing the structural stability and ensuring the quality of product use.
[0023] At the same time, the fan blade 2 is provided with a positioning buckle 21, and the guide connecting block 3 is provided with a positioning buckle hole 32 for matching and snapping with the positioning buckle 21.
