Claim 4:
5. The inflation pump connector suitable for various valves as claimed in claim 4, wherein the sliding groove includes an inner periphery having an annular protrusive portion and an annular recessed portion, wherein a width of the annular protrusive portion perpendicular to the longitudinal axis is smaller than a width of the annular recessed portion perpendicular to the longitudinal axis, wherein the annular recessed portion is contiguous to the annular protrusive portion and is located on a side of the annular protrusive portion adjacent to the rear end of the housing, wherein each of the first, second, and third clamping arms includes a first push portion disposed on an outer periphery thereof surrounding the longitudinal axis, wherein a distance between the first push portion of each of the second clamping arm and the third clamping arm and the longitudinal axis is greater than a distance between the first push portion of the first clamping arm and the longitudinal axis, wherein each of the fourth, fifth, and sixth clamping arms includes a second push portion on an outer periphery thereof surrounding the longitudinal axis, wherein a distance between the second push portion of each of the fifth clamping arm and the sixth clamping arm and the longitudinal axis is greater than a distance between the second push portion of the fourth clamping arm and the longitudinal axis, wherein when the pressing device is in the first state, the first and second push portions are located between the annular protrusive portion and the front end of the housing, and wherein when the pressing device is in the second state, the annular protrusive portion presses against the first and second push portions, and the first and second push portions move into and are positioned in the annular recessed portion.
