A duplex control structure of toy gun includes a main body (3), a control portion (1), a transmission portion (2), and a motor (4). The main body (3) further consists of a left and right main bodies (3a), (3b), a
barrel (31), two motor's positioning plates (32a) and (32b), a multiplicity of supporting shaft rods (33), (34), a left and right
handle portions (35a), (35b), check plates (36a), (36b), and two sliding ways (37a), (37b). The control portion (1) further consists of a trigger (11), a
control rod (12), a propping up plate (13), a
brake (14), a slider rod (15), a positioning plate (25), a pull knob (17), and a power switch (18). The transmission portion (2) consists of a gun
machine socket (21), a
piston (22), springs (23), (24), a positioning plate (25), a check piece (26), a clip piece (27), a small transmission gear (28), and a large transmission gear (29). The motor (4) is connected to a DC power supply. By making use of the pull knob (17) to drive the propping up plate to press against or separate from the corresponding
control rod (12) in accommodating the action of the positioning plate (25) of the control portion (1), the invention is capable of achieving the objective of duplex driving functions of a manually and electrically shooting toy gun.
