1. A structure for fast mounting of ceiling fan blades, comprising a motor fixing base for placing a motor, a plurality of blades, and a blade mounting structure, wherein the blade mounting structure comprises a fast self-locking pressuring block, a bolt, and elastic pressuring block reset members:
the fast self-locking pressuring block is arranged in a guide slot of the motor fixing base and is capable of sliding up and down in the guide slot; the fast self-locking pressuring block is provided with blade locking pins and threaded holes; after the fast self-locking pressuring block is arranged in the guide slot of the motor fixing base, a plug-in blade mounting opening is formed between the fast self-locking pressing block and the motor fixing base;
the bolt is inserted into a through hole of the motor fixing base and screwed into one of the threaded holes of the fast self-locking pressuring block;
the elastic pressuring block reset member of the pressuring block is arranged in the guide slot of the motor fixing base, so that the fast self-locking pressuring block is capable of tending to slide in the guide slot outwardly to open the plug-in blade mounting opening; when the plug-in blade mounting opening is in an opened state, an inner end of the blade can be movably inserted into and pulled out of the plug-in blade mounting opening; and
a locking pin insertion hole is formed at the inner end of the blade; when the inner end of the blade is inserted into the plug-in blade mounting opening, and when the bolt is screwed to narrow the plug-in blade mounting opening, one of the blade locking pins can be inserted into the locking pin insertion hole of the blade.
