A flexible large-deformation constant-force-transmission three-dimensional force sensing mechanism comprises a pedestal, a force measuring platform and three force measuring branches with the same structure and connected to the pedestal and force measuring platform. The pedestal is of a trigonal pyramid shape, three ribs are orthogonal with one another, and the whole pedestal is distributed in a radial way; each force measuring branch comprises a moving pair composition member, a first bolt bearing, a first connecting rod, a second bolt bearing, a second connecting rod, a third bolt bearing, an upper platform seat and a tension and compression type force sensor; the moving pair composition member a guide rail, a slide block and a bidirectional pressure spring device; and the bidirectionalpressure spring device comprises springs with the same pretightning force, a spring sleeve, a spring rod and an end cap. The flexible large-deformation constant-force-transmission three-dimensional force sensing mechanism is
