The reaction cup carrying device as claimed in claim 4, wherein the Z-axis driving assembly further includes a fixing base, a first driving member, and a guide shaft, the first driving member is mounted on the fixing base, the first driving member is connected to the driving shaft of the first driving member, the gripping mechanism is connected to the first driving member, the guide shaft is connected to a surface of the first driving member facing the first driving member and is disposed parallel to the driving shaft, and the fixing base is provided with a guide hole for the guide shaft to pass through.

6. The apparatus of claim 4, wherein the Y-axis driving assembly comprises a second driving member, and a driving shaft of the second driving member is connected to the Z-axis driving assembly to drive the Z-axis driving assembly to move the reaction cup in the Y-axis direction.

7. The reaction cup transporting apparatus as claimed in claim 6, wherein the Y-axis driving assembly further includes a second driving member, a moving member and a track, one end of the second driving member is connected to the driving shaft of the second driving member, the moving member is connected to the other end of the second driving member, the track is slidably engaged with the moving member, the second driving member drives the second driving member to move so as to drive the moving member to move on the track in the front-rear direction, and the Z-axis driving assembly is connected to the moving member.

8. The cuvette handling apparatus of claim 7, wherein a plurality of said rails are provided, a plurality of said rails are arranged in parallel and stacked in the Z-axis direction, one of said rails is slidably connected to the other rail; and/or the presence of a gas in the gas,

9. The reaction cuvette handling apparatus of claim 6, wherein the rotary drive assembly comprises a third driving member and a rotary plate connected to a driving shaft of the third driving member, the Y-axis drive assembly being mounted to a surface of the rotary plate facing away from the third driving member to achieve the rotary motion in the horizontal direction.

10. The reaction cup handling apparatus of claim 9 wherein the X-axis drive assembly comprises a fourth drive member and a third drive member, the drive shaft of the fourth drive member being coupled to the third drive member, the rotary drive assembly being coupled to the third drive member to effect X-axis translation.
