Abstract

The invention discloses a self-adjustment connecting device and a screw-nut transmission device using the same. The self-adjustment connecting device comprises a base and a nut fixing seat, wherein the nut fixing seat is used for fixing the screw nut; a floating insertion structure is arranged between the nut fixing seat and the base; the floating direction of the floating insertion structure is perpendicular to the axial direction of the screw nut; and the base and the nut form a drag fit in the axial direction of the screw nut through the floating insertion structure. In the invention, the traditional integrated connecting seat is separately arranged, so that the nut fixing seat can slide in the radial direction of the screw nut relative to the base. In the working process, when the elongated screw shifts in the radial direction, the nut fixing seat which is rotatably matched with the screw can move in the preset direction relative to the base, thereby solving the problem of clamping in the elongated screw transmission process.
