A hemispherical string type universal positioning clamp comprises a clamping mechanism, a connector, a universal adjusting mechanism, a tensioning positioning mechanism and a supporting mechanism. Theclamping mechanism is connected with the universal adjusting mechanism through the connector. The universal adjusting mechanism is provided with a plurality of hemispherical bowls and expansion bowlswhich are overlapped and connected in series; a first central positioning hole and a first tensioning hole are formed in the bottom surface of each hemispherical bowl, a friction joint surface is formed by the inner spherical surfaces and the outer spherical surfaces of every two adjacent hemispherical bowls, a second central positioning hole and a second tensioning hole are formed in the bottomsurface of each expansion bowl, and a group of radial radiation open slots are formed in the side wall of each expansion bowl; the tensioning positioning mechanism is matched with the universal adjusting mechanism to fix the position of the clamping mechanism; the supporting mechanism is used for fixing the hemisphere string type universal positioning clamp to a base of an operation site. By the adoption of the hemispherical string type universal positioning clamp, the requirement that the operating rod is fixed to the neutral position in the maintenance process of an aircraft control system is met.
