Three-degree-of-freedom reversing device

The invention provides a three-degree-of-freedom reversing device which comprises a base body, a first mover, a second mover, a third mover, a YZ-axis reversing transmission mechanism and an execution piece, the horizontal rightward direction on the base body serves as the positive direction of the X axis, and the horizontal forward direction on the base body serves as the positive direction of the Y axis. Establishing a space rectangular coordinate system by taking a vertical upward direction on the base body as a Z-axis positive direction; the first mover, the second mover and the third mover are movably arranged on the base body in the direction parallel to the X axis, and the YZ-axis reversing transmission mechanism is in linkage transmission among the first mover, the second mover, the third mover and the execution piece at the same time. The YZ-axis reversing transmission mechanism converts displacement transmission of the first rotor, the second rotor and the third rotor in the X-axis direction into di
