A tire pump includes a reciprocal member having a first end and a second end, and a handle having a first end and a second end. The first end of the handle is mounted on the second end of the reciprocal member. The handle includes a switch member mounted on the first end thereof. The switch member may be operated by a user's one hand only so that the switch member may be moved between a first position where the second end of the reciprocal member is fixed on the first end of the handle, and a second position where the second end of the reciprocal member may be retracted into the first end of the handle.
