[0031] Among them, a groove is provided in the middle of the connecting column 46. When the valve core cover 47 is plugged into the connecting column 46, the connecting column 46 on both sides can be squeezed by utilizing the function of the groove. Then, due to the function of the groove, the connecting column 46 after being squeezed can be plugged and fixed with the valve core cover 47 to prevent the valve core cover 47 from being lost during inflation.
