1. A ground testing device for a stabilized platform of a rotary steerable drilling tool, comprising a drill collar assembly, wherein the drill collar assembly comprises a drill collar and a drill collar motor, and a stabilized platform mounting assembly is arranged inside the drill collar for mounting the stabilized platform; the ground testing device further comprises:
a first supporting member, wherein the drill collar motor is mounted outside the first supporting member, and a motor shaft of the drill collar motor penetrates the first supporting member and is connected to the drill collar;
a second supporting member arranged opposite the first supporting member and provided with a first mounting hole; and
a vibration mechanism comprising a first vibration member connected to the drill collar and a second vibration member arranged in the first mounting hole in a sleeved manner, wherein an elastic member is arranged between the second vibration member and the second supporting member, the elastic member is arranged on the second vibration member in a sleeving manner, an end portion of the first vibration member is provided with first vibration teeth, an end portion of the second vibration member is provided with second vibration teeth matching the first vibration teeth, in a rotation process of the drill collar, the second vibration teeth are separated from the first vibration teeth and meshed with the first vibration teeth under an action of the elastic member, so as to automatically open and close to generate vibration, and the second vibration member is provided with a first stop member which matches a second stop member arranged in the first mounting hole, so as to prevent the second vibration member from rotating around an axis of the drill collar when moving in an axial direction of the drill collar.
