The invention relates to a high-frequency swinging type releasing tool used for relieving drilling tool jamming accidents in petroleum and gas industry drilling operation. The problem of efficient releasing incapability of a drilling string after the drilling tool jamming is solved. The high-frequency swinging type releasing tool has the technical scheme that a turbine stator blade disc and a turbine rotor blade disc are sleeved together to form turbine assemblies; the three sets of turbine assemblies are sequentially sleeved onto the upper part step shaft of the rotating shaft; a thrust bearing is arranged onto a lower part projected step of the inner cavity of the stator casing; the rotating shaft, the turbine rotor blade disc and the turbine stator blade disc are put into an inner cavity of the stator casing; the upper part of a cam shaft and the lower part of the rotating shaft are connected through screw threads; an upper pendulum shifting fork and a lower pendulum shifting fork are arranged in an inner cavity of a tube body; a pin shaft passes through a middle part pin shaft hole of the upper pendulum shifting fork and a middle part pin shaft hole of the lower pendulum shifting fork; the pin shaft is fixed in the lower part pin shaft hole of the tube body; a spline arranged at the lower end of the tube body is inserted into an upper end spline of the inner cavity of a lower connector; an anti-falling cap is connected with the upper end of the lower connector through screw threads. The lower connector does high-frequency reciprocating swinging; the releasing of the drilling tool jamming string can be effectively assisted.
