The invention discloses a launcher for a meteorological sounding rocket. The launcher for the meteorological sounding rocket comprises a connecting rod, a shaft pin A, a shaft pin B, a first gasket, afirst nut, a second nut, an orientator, a supporting seat and a traction chassis. The launcher for the meteorological sounding rocket is stable in overall structure and suitable for operation under severe weather conditions; a launching angle adjusting mechanism adopts a connecting rod mechanism for driving a screw rod to transmit by a motor; the orientator adopts four guide rails to be combinedwith a middle ring A and a middle ring B to form a launching rail, the launching caliber is 122 mm, the maximum angle of the high-low launching angle is not less than 80 degrees, the height of the launcher in the transportation state is not larger than 3 m, and the stability is high; a supporting part adopts the motor to drive a trapezoidal lead screw shaft to rotate to drive the connecting rod tomove front and back so as to achieve the purpose of adjusting the launching angle, and a manual mode can be quickly switched; and a rocket operation automatic parameter recording instrument or a wireless launching controller can be used for control, and a high-power lithium battery is carried, so that the field power supply problem is solved.
