Claim:
1. A tape applicator having an edge folding structure, comprising: a main body, the main body having a side board at one end thereof, the side board being provided with a blade, a press roller, and a tape seat; an edge folding block, the edge folding block comprising a base, the base having a first end and a second end positioned to the side board, the base being pivotally connected with a folding post adjacent to the first end of the base, a gap being defined between a bottom surface of the folding post and the side board, a top surface of the base being provided with a press board and a reverse folding member, a passage being defined between the press board and the reverse folding member, one side of the reverse folding member having an inclined surface relative to the passage, the base being provided with a flattening board adjacent to the second end of the base, the flatting board having an end portion extending towards the passage; thereby, through a pulling force of a tape when the tape is applied, a side edge of the tape falling into the gap and being reversely folded when the tape passes the reverse folding member, and then the tape being flattened by the end portion of the flattening board to form a folded side edge; and the reverse folding member comprising a reverse folding block relative to the first end, the passage being formed between the press board and the reverse folding block, one side of the reverse folding block having a first inclined surface relative to the passage; the reverse folding member further comprising a reverse folding reinforcement block connected to the reverse folding block relative to the second end, the passage being formed further between the press board and the reverse folding reinforcement block, one side of the reverse folding reinforcement block having a second inclined surface relative to the passage; the second inclined surface being parallel to the first inclined surface; the second inclined surface protruding out of the first inclined surface, such that the reverse folding reinforcement block is formed with a protruding portion; and the inclined surface comprising the first inclined surface and the second inclined surface.
