The sliding of 335 stably clamps the plastic ring 331, so that it is firmly connected to the output end or input end of the cooling system water pump 23. Then, the cooling system water pump 23 can be started by connecting the wire to the external power supply, and the cooling water added by the water inlet 32 ​​in the cooling water supply tank 3 is pumped out and injected into the inner cavity of the temporary storage tank 4 through the water delivery hose 41. At the same time, the operator sets a specified time to stop the power supply of the cooling system water pump 23, and then starts the electric control valve 44 to collect the cooling water in the temporary storage tank 4 through the guide plate 42 and the L-shaped water delivery pipe 4 3 is injected into the transparent metering cylinder 12, and the water volume is observed by the scale line 121 on the front side of the transparent metering cylinder 12, and then the water pump is replaced and the operation is repeated.
