The CT scanning device of claim 1, wherein said bearing bracket and said supporting base are coupled at two tilting and wiggling points respectively located at a left side and a right side under the rotating center of said scanning gantry. 3. The CT scanning device of claim 2, wherein said supporting means surrounds and crosses said scanning gantry from back and forth, and wherein said supporting means at both sides of a bore of said scanning gantry are respectively connected to said supporting base at the same side therewith through two parallel connecting linkages, such that connection points between said connecting linkages and said supporting means and said supporting base are connected by bearings. 4. The CT scanning device of claim 3, further comprising a driving connecting bar connecting said bearing bracket and one of said connecting linkages, such that connection points between said driving connecting bar and said bearing bracket and said connecting linkages are connected by bearings. 5. The CT scanning device of claim 4, wherein a connecting line between the tilting and wiggling point and the connection point of said driving connecting bar and said bearing bracket passes through the rotating center of said scanning gantry and is parallel to said connecting linkages. 6. The CT scanning device of claim 5, wherein a connecting line between two connection points of said two connecting linkages and said supporting base is parallel to the connecting line between two connection points of said two connecting linkages and said supporting means. 7. The CT scanning device of claim 6, the two connection points of said two connecting linkages and said supporting means are at a same height as the rotating center of said scanning gantry. 8. The CT scanning device of claim 2, wherein said supporting means surrounds and crosses said scanning gantry, said supporting means at both sides of a bore of said scanning gantry are respectively connected to said bearing bracket at a same side therewith through bearings and to said supporting base at the same side therewith through connecting linkages, and the two ends of said connecting linkage are respectively connected to said supporting means and said supporting base through bearings. 9. The CT scanning device of claim 8, wherein a line connecting the tilting and wiggling point for tilting and wiggling of said scanning gantry and a connection point between said bearing bracket and said supporting means is parallel to said connecting linkage, such that a line connecting the connection point of said connecting linkage and said supporting means and the tilting and wiggling point is parallel to the line connecting the tilting and wiggling point and the connection point between said bearing bracket and said supporting base. 10. The CT scanning device of claim 9, wherein the connection point of said bearing bracket and said supporting base is at the same height as the rotating center of said scanning gantry. 11. The CT scanning device of claim 10, wherein said supporting means comprises an upper frame and a lower frame, said bearing bracket and said connecting linkages are connected to said upper frame. 12. The CT scanning device of claim 11, wherein said upper frame and said lower frame are connected at a same side thereof through a parallelogrammic mechanism, and the connection points are all connected by bearings. 13. The CT scanning device of claim 12, said upper frame and said lower frame at the same side are connected through two connecting linkages between said upper frame and said lower frame, and said upper frame, said lower frame, and said two connecting linkages form a parallelogram, wherein using the two connection points on said upper frame as axis points, upward and downward movement of said lower frame is adjustable by controlling said parallelogrammic mechanism. 14. The CT scanning device of claim 13, wherein said scanning table is located on said lower frame, said lower frame comprises rollers arranged thereon for supporting said scanning table, said CT scanning device further comprising a roller driver configured to drive said rollers to move so as to make said scanning table to move forward or backward. 15. The CT scanning device of claim 14, further comprising a carriage for supporting and driving said scanning table to move up and down, and said roller drivers is arranged on said carriage. 16. The CT scanning device of claim 15, wherein said carriage is connected to a guide rail of said supporting means through a ball screw, and said ball screw drives said carriage to move up and down along said guide rail. 17. The CT scanning device of claim 16, wherein said carriage comprises a tongue along at least a portion of a front side, such that when said carriage reaches a lowest scanning height, said tongue comes into parallel contact with said parallelogrammic mechanism, and said roller driver will drive said scanning table from said carriage into said supporting means, and when said carriage continues to move up, said tongue will push said parallelogrammic mechanism of said supporting means to move up, thus keeping said carriage to be always in parallel contact with said parallelogrammic mechanism of said supporting means. 18. A CT scanning device, comprising: a scanning gantry;a supporting means for a scanning table;a supporting base for fixing and supporting said scanning gantry, wherein said scanning gantry is configured to scan a subject and to collect scanning data, said supporting means supports said scanning table, and said supporting means is mounted on said supporting base and located between said scanning gantry and said supporting base; anda bearing bracket for fixing and mounting said scanning gantry, such that said scanning gantry is mounted on said supporting base through said bearing bracket, and a connection point between said bearing bracket and said supporting base is a tilting and wiggling point of said scanning gantry, around which said scanning gantry can tilt and wiggle. 19.
