The invention discloses a manual type air blow device for filed fire blowing. The manual type air blow device comprises a base shell; a first side seat is arranged on one side of the base shell, and a second side seat is arranged on the other side of the base shell; a top shell is arranged on the base shell and installed between the first side seat and the second side seat; an opening hole is formed in the top of the top shell; an air bag is arranged in the base shell and the top shell; a plurality of air blowing holes are formed in the side wall of the first side seat; the surface of the air bag is of a sealed structure, and the air bag communicates with the air blowing holes; a push-pull mechanism is arranged in the base shell and the top shell and comprises a reciprocating column; one end of the reciprocating column is connected with the air bag, and the other end of the reciprocating column is connected with a pulling frame; the pulling frame is connected with a pulling rod; a rotating shaft is inserted into the opening hole; a rotating gear is arranged at the upper end of the rotating shaft; and a rotating disk is arranged at the lower end of the rotating shaft. The air bag can be controlled to be compressed or expanded, accordingly the air blow effect can be conveniently achieved, and the air bag can achieve air blow through the air blow holes, so that filed fire blowing is facilitated.
