[0049] In use of the fluid delivery assembly 2, the second driving member 23 can be first activated to drive the first housing 21 to rotate, so that the fluid delivery assembly 2 is extended outwardly as a whole, and then the first driving member 13 is activated to drive the second delivery pipe 12 to rotate relative to the first delivery pipe 11, so that the fluid delivery assembly 2 is extended to a designated position, and the output port 122 is aligned with a position where fluid is needed to be outputted, and then fluid needed to be delivered can be inputted from the input port 112, so that the fluid flows through the first flow channel 111 and the second flow channel 121 in sequence and is outputted through the output port 122. After the fluid delivery operation is completed, the driving directions of the first driving member 13 and the second driving member 23 can be reversed, so that the fluid delivery assembly 2 is reversely moved and returned to the initial position, so as to facilitate storage of the fluid delivery assembly 2 and save the overall occupied space.

And, through the above two kinds of movement form mutual cooperation, can realize the accurate adjustment of the whole attitude of fluid delivery assembly 2, reduce the error of movement, thereby improve the accuracy of movement and the precision of the output port 122 aligning the output position. Meanwhile, since the movement of first housing 21 and the movement of second delivery pipe 12 relative to first delivery pipe 11 are all rotation around the axis, the movement mode is simple, therefore, first driving member 13 and second driving member 23 can all adopt the components such as reduction motor output torque, compared with the components such as electric push rod output linear power, reduce the component cost, and do not need to reserve the space of electric push rod activity, save the occupied space, can also optimize the structure layout and line arrangement, the overall structure is relatively simple, thereby reduce the assembly difficulty.
