The longitudinal groove is recessed inwardly from the connecting end. The lens structure is integrally formed with the cap, the lens structure is located between the receiving groove and the longitudinal groove, and the lens structure blocks spatial communication between the receiving groove and the longitudinal groove. Each of the pillar structures is connected to an inner wall that surrounds the receiving groove.
