When the fan blade 6 needs to be replaced, only the connecting piece 8 is needed. The two push-pull blocks 15 on the surface are pushed to the inside at the same time, so that the triangle block 14 gradually shrinks into the spring chamber 16. When the triangle block 14 is completely retracted into the spring chamber 16, the fan blade 6 is moved to the top of the connecting piece 8. By pulling, the top end of the connecting piece 8 can be drawn out from the inside of the fixing base 13, so that the fan blade 6 can be replaced. After the replacement is completed, the top end of the connecting piece 8 is inserted into the fixing base 13, and the triangular block 14 will change when inserted. Is squeezed into the spring chamber 16 so that the top end of the connecting piece 8 can be smoothly inserted into the fixing seat 13. When the top end of the connecting piece 8 is completely inserted into the fixing seat 13, the triangular block 14 will interact with the rectangular hole on the outside of the fixing seat 13 Coincide, the triangular block 14 is no longer squeezed and is ejected to the outer surface of the fixing seat 13 under the action of the inner spring of the spring chamber 16, and then the connecting piece 8 and the fixing seat 13 can be fixedly connected, so that The fan blade 6 is fixed on the top of the connecting piece 8, so that the replacement process of the fan blade 6 becomes faster, and stable and reliable;

When the protective net 2 needs to be disassembled from the surface of the body 1, just manually separate the spring hasp 3 from the hook on the top of the pendant 9. Without the fixing action of the spring hasp 3, the protective net 2 can be easily removed from the body 1 When you need to fix the protective net 2 on the surface of the body 1 later, since the surface of the body 1 is provided with a hanging groove 10 corresponding to the pendant 9, you only need to align the pendant 9 on the surface of the protective net 2 with the hanging groove 10 Push in the inside, and then fasten the spring buckle 3 with the hook on the top of the pendant 9, then the protective net 2 can be fixed on the surface of the body 1 again, so that the protective net 2 can be quickly disassembled and installed, which is convenient for the body 1. At the same time as the internal maintenance, it is also convenient to clean the protective net 2.

Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it will be understood that various changes and modifications can be made to these embodiments without departing from the principle and spirit of the present invention. , Substitutions and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
