The invention provides a method and device for stopping an external suspension of a helicopter. The device comprises a shell, a central tilting assembly, a swing triggering assembly, a high-pressure gas cylinder and a rotation control assembly. Wherein the shell is composed of a barrel body, a central tilting assembly fixing ring, a swing-stopping gas spraying pipe, an annular gas cavity, a gas inlet one-way valve, a high-pressure gas cylinder cavity, a rotation-stopping shifting fork rotating table, a rotation-stopping shifting fork rotating cavity, a gas conveying one-way valve, a swing-stopping gas spraying opening and an external connecting table; the central tilting assembly is composed of a top column, an upper spherical cavity, an upper spherical cone, a flange ring, a lower spherical cavity, a lower spherical cone, a collision ring and a balance weight cake. The swing triggering assembly is composed of a swing stopping hanging ring, a swing stopping hinge, a swing stopping shifting fork hanging column, a swing stopping shifting fork air inlet hose, a swing stopping shifting fork air injection hose, a swing stopping shifting fork and a swing stopping switch assembly. The rotation control assembly is composed of a rotation stopping shifting fork, a rotation stopping collision table, a spring, a rotation stopping air inlet pipe, a rotation stopping switch assembly, a rotation stopping air spraying pipe, a rotation stopping air spraying channel and a rotation stopping air spraying opening.
