The connecting member 3 includes a first through hole 31 through which the first rotating shaft 11 is disposed, a second through hole 32 through which the second rotating shaft 21 is disposed, and a first through hole 32. The obstruction portion 33 between the 31 and the second insertion hole 32, and a sliding positioning portion 34 provided on the rail portion 33 to slide along the rail portion 33. The sliding positioning portion 34 is engaged with the first positioning groove 111 by the second abutting portion 212, and restricts the rotation of the first rotating shaft 11 to have a first limiting state, and the sliding positioning portion 34 is received by the sliding positioning portion 34. The first abutting portion 112 abuts against the second positioning groove 211, and restricts the rotation of the second rotating shaft 21 to have a second restricted state. [0016] In a specific implementation of the present invention, the first rotating shaft 11 further has a first limiting portion 113, and the second rotating shaft 21 further has a second limiting portion 213, and the connecting member 3 further includes A first positioning portion 35 for restricting the rotation of the first rotating shaft 11 and a second positioning portion 36 for restricting the rotation of the second rotating shaft 21 with the second limiting portion 213 are respectively abutted against the first limiting portion 11 3 . . In addition, the stable opening and closing@biaxial hinge disclosed in the present invention further includes a sleeve 4 and a housing 5 for housing the sleeve 4.

[0017] Please refer to FIG. 4-1 to FIG. 4-5, which is a schematic diagram of the operation of the biaxial hinge of the stable opening and closing, as shown in the figure: the stable opening and closing biaxial hinge can be applied to the pivoting 10120202# single thief deletion 1 Page 8 / Total 22 pages 1012006279-0 M430142 type electronic device 6 'such as a notebook computer, tablet computer, mobile phone, etc., the first assembly of the first rotating member 1 (shown in Figure 1) 12 is connected to the upper cover 61 of the electronic device 6, and is connected to the lower cover 62 of the electronic device 6 through the second assembly portion 22 of the second rotating member 2 (not shown in FIG. 4). When the upper cover 61 is closed to the lower cover 62, the sliding positioning portion 34 simultaneously restrains the rotation of the second rotating shaft 21 against the second positioning groove 211 and the first abutting portion ι 2, and the second rotating shaft 21 The second limiting portion 213 (shown in FIG. 2) abuts against the second positioning portion 36 of the connecting member 3 to form a limit relationship. When the upper cover 61 is biased, the rotational torque of the first rotating shaft π is smaller than the rotational torque of the second rotating shaft 21, and therefore, the second rotating shaft 21 and the housing 5 are kept stationary, and the upper cover 61 is held. The first rotating shaft 连 is rotated relative to the first rotating shaft 21 and the casing 5, and the sliding positioning portion 34 is still abutted by the first abutting portion 112 to engage with the second positioning groove 211. , the first rotating shaft 21 is restricted to rotate (as shown in FIG. 4-2). Continuing to force the upper cover 61 to rotate the upper cover 61 to rotate the first rotating shaft 11 to a degree, the opening portion of the first positioning groove 111 of the first rotating shaft 丨1 and the second portion of the second rotating shaft 21 The positioning groove 21 is opposite to the opening portion. At this time, the sliding positioning portion 34 is freely slid along the rail portion 33 on the connecting member 3 without being abutted by the first abutting portion 112, and the second rotating shaft 21 is slid. Therefore, it is free from rotation by the sliding positioning portion 34. At the same time, the first limiting portion 113 of the first rotating shaft 11 abuts against the first positioning portion 35 ′ of the connecting member 3 to form a limit relationship 'limits the first rotating shaft 11 to continue to rotate (as shown in FIG. 4-3 ). ). [0019] If the upper cover 61 is continuously pivoted, since the first rotating shaft 11 and the connecting member 3 are configured to be in a limit position, it is required to be larger. The force of the housing 5 is rotated relative to the second rotating shaft 21, so that the second limiting portion 213 of the second rotating shaft 2 is disengaged from the second positioning portion 36 of the connecting member 3, so that the upper cover 61 pivots more than 180 degrees, at the same time, the sliding positioning portion 34 is disengaged from the second positioning groove 211, and is engaged by the first abutting portion 212 to be engaged in the first positioning groove ηι, thereby limiting the first rotating shaft 11 Rotate at the same time (as shown in Figure 4-4). When the upper cover 61 is continuously rotated to 360 degrees, the sliding positioning portion 34 is still engaged by the first abutting portion 212 and is engaged in the first positioning groove lu, so that the first transfer 11 cannot be Simultaneously rotating, at this time, the upper cover 61 has been fully pivoted to the lower side of the *under the lower cover 62 (as shown in Figure 4-5). To return the upper cover 61 to the upper cover 62, the lower cover 62 is biased. When the lower cover 62 is rotated 180 degrees, the second limiting portion 213 of the second rotating shaft 21 and the connecting member The second positioning portion 36 of the third portion abuts, and constitutes a limit relationship to stop the rotation of the second rotating shaft 21. Then, the lower cover 62 is continuously rotated, and the sliding positioning portion 34 is engaged by the first abutting portion 112 and is engaged with the second positioning groove 211. After the lower cover 62 is rotated 180 degrees, the upper cover 61 is again covered above the lower cover 62. [0021] As described above, the present invention uses the sliding positioning portion 34 to simultaneously abut the first positioning groove 111 and the second abutting portion 212, and the first rotating shaft u is received by the sliding positioning portion 34. The second positioning shaft 211 and the first abutting portion 112 are simultaneously restrained by the sliding positioning portion 34 and cannot be rotated. In this way, there is no problem that the two axes rotate at the same time.
