10. A method of angiography using an angiography device with a deflection-fitting protective shell according to any one of claims 1-9, characterized in that: the method comprises the following steps:

S1: the medical staff lie on the examination bed (10) so that the X-ray emission head (8) is positioned above the medical staff and the detection receiving head (9) is positioned below the medical staff;

s2: the X-ray emitting head (8) is driven by the emitting head height adjusting mechanism to approach to medical staff through the control center (25);

S3: the protective shell (18) is driven by the protective shell height adjusting mechanism to approach medical staff through the control center (25);

S4: according to the actual checking position of the medical staff, the C-arm (4) is adjusted by the frame body adjusting mechanism through the control center (25), and the connecting column (7), the X-ray transmitting head (8) and the detecting receiving head (9) are driven to conduct angle deflection;

S5: under the action of the spherical seat (12) and the annular frame (13), the deflection limiting mechanism is matched, so that the deflection of the protective shell (18) is limited by the deflection limiting mechanism, and the protective shell (18) masks the X-ray emission head (8) and does not deflect along with the connecting column (7), the X-ray emission head (8) and the detection receiving head (9);

s6: after the inspection is completed, the C-arm (4) is driven by the frame body adjusting mechanism to reset through the control center (25), so that a connecting line between the X-ray emitting head (8) and the detection receiving head (9) is in a vertical state;

s7: through control center (25), protective housing height adjustment mechanism drives protective housing (18) upward movement and keeps away from personnel of seeking medical advice, the X-ray emission head (8) upward movement is kept away from personnel of seeking medical advice to the transmission head height adjustment mechanism, personnel of seeking medical advice follow inspection bed (10) are taken up and are left.
