The support base 3 is provided in the terminal device M to which the connector M0 belongs. Specifically, in this embodiment, the support base 3 is provided on the M housing of the terminal device. For example, for a notebook computer, since the connector M0 is located In the D shell, therefore, the support seat 3 is arranged on the D shell. The supporting base 3 is rotatably connected with the supporting frame 2, so that the supporting frame 2 can drive the connecting substrate 1 and the connector M0 to rotate relative to the supporting base 3, so as to adjust the pitch angle of the connector M0. In addition, it should be noted that, in this embodiment, the connector M0 is not limited to a female socket structure, and the connector M0 and the connecting plug P only need to have a plug-in connection structure that cooperates with each other.

As shown in FIG. 3 and FIG. 4 , a bearing groove 30 is provided on the supporting seat 3 , and a rotating shaft 20 adapted to the bearing groove 30 is arranged on the carrier frame 2 . In this embodiment, the two ends of the bearing frame 2 respectively have a rotating shaft 20, correspondingly, two supporting seats 3 arranged oppositely are arranged, and the carrying frame 2 is erected on the two supporting seats 3 based on the two rotating shafts 20 at both ends, When a rotational moment is applied to the rotating shaft 20 , the supporting frame 2 rotates.
