In the rotation process of the sleeve 33, the liquid wheel bracket C moves towards the support tube 321 along the axial direction y of the internal thread of the groove on the liquid wheel bracket, and then the meter body T can be separated. The length h of the supporting cylinder 321 is greater than the length s of the liquid wheel support C in the axial direction y of the internal thread of the groove, so that the liquid wheel support C can completely leave the meter body T and enter the hollow area of the supporting cylinder 321, and the supporting cylinder and the liquid wheel assembly can be taken out together subsequently, and the structure enables the liquid wheel dismounting device to be more efficient.

Optionally, the fluid wheel assembly removal device 30 further includes a handle 34, and the handle 34 is connected to the outer wall of the sleeve 33.
