Radial and axial double-floating adjusting type rudderstock

The invention discloses a radial and axial double-floating adjusting type rudderstock which comprises a rudderstock body, floating convex blocks, a radial adjusting mechanism and an axial adjusting mechanism. A clamping ring body outside a traditional rudderstock body is decomposed into a plurality of floating convex blocks for clamping rotation, a floating threaded barrel is driven to move up and down through rotation of an adjusting screw rod, so that an abutting block is driven to move up and down, a radial abutting plate is driven to slide in the radial direction, and the floating convex blocks are driven to slide in the radial direction through radial penetrating columns; meanwhile, radial sliding columns on the upper sides of the floating convex blocks can synchronously slide in the longitudinal floating sleeve in the radial direction, and when the abutting ring body rotates to move up and down, the longitudinal floating sleeve can be driven to move up and down; therefore, the floating protruding blocks
