The invention discloses a full-digital color Doppler ultrasonic diagnosis apparatus which comprises a machine case and a support frame structure, wherein an operation and control seat is fixed at themiddle part of the top end of the machine case through screw bolts; the top end of the back part of the machine case is rotationally connected with the support frame structure; a connecting block is welded at one end of the support frame structure; a first motor is connected onto one side wall of the connecting block through a key; and the first motor is fixed to the inner wall of the machine casethrough screw bolts. The full-digital color Doppler ultrasonic diagnosis apparatus has the beneficial effects that through the arrangement of the support frame structure, a turntable, the first motorand a second motor, the multi-angle position regulation of a display screen in the diagnosis apparatus can be realized, so that a user can conveniently take a close look at frequency spectrum detailson the display screen; the operation of the device is not influenced; and the practicability of the device is improved.
