The invention discloses a continuous measuring device for the space attitude of a bottom drilling tool. The continuous measuring device comprises a measuring nipple, and is characterized in that the measuring nipple comprises a measurement and control box, and an accelerometer and a gyroscope are arranged in the measurement and control box; the measuring nipple further comprises a first servo motor and a second servo motor, the first servo motor can drive the measurement and control box to move in the axial direction of a rotary shaft of the first servo motor through a transmission mechanism, and the second servo motor can drive the measurement and control box to rotate; the first servo motor is connected with a first rotary transformer, and the second servo motor is connected with a second rotary transformer. According to the continuous measuring device, under the condition that continuous measuring of the space attitude of the drilling tool is kept, a complex environment in a drilled well and measurement noise generated by vibration of a drill column can be effectively eliminated.
