The utility model discloses a double-shaft co-action pivot device capable of eliminating clearance between a gear shaft and a gear. The double-shaft co-action pivot device comprises a first pivot and a second pivot which are opposite to each other, wherein two pivots are movably sleeved with two opposite location partition plates; a gear shaft sleeve linked with two pivots are sleeved between the pivots and the location partition plates; one end of the gear shaft sleeve is close to one location partition plate; opposite gear parts are respectively arranged on the other side of the gear shaft sleeve; the other opposite partition plate is assembled with a gear bearing bracket; one end of the gear bearing bracket is connected with the other opposite partition plate in an inserted manner; the other end of the gear bearing bracket is jointed with one gear shaft; the gear shaft is arranged in the gear shaft sleeve and engaged and linked with opposite gear parts of the gear shaft sleeve by taking a shaft body of the gear shaft as an end gear, thereby generating double-shaft co-action effect in the double-shaft co-action pivot device by using a transmission mechanism with simplified size, improving the shake of an electronic device when acting and eliminating idle stroke in the opening and closing process.
