Abstract:
A straw, comprising a main tube (1) and two telescopic outer tubes (2). The two telescopic outer tubes (2) are sleeved outside the main tube (1) separately, and can be pulled out outward or retracted inward with respect to the main tube (1); the main tube (1) is connected to the two telescopic outer tubes (2) separately by means of connecting structures. During use of the straw, the length of the straw can be adjusted in real time according to requirements. A protruding tube (3) fits and sleeved to a neck (4). A simple structure is achieved. The protruding tube (3) and the main tube (1) are an integrated structure, and the junction between the protruding tube (3) and the main tube (1) is arc-shaped. The arc shape fits the shape of the neck (4), thereby achieving better sealability. The main tube (1) and the two telescopic outer tubes (2) are both stainless steel tubes. A stainless steel material can be reused. The straw is easy to store and use. The environmental pollution can be effectively reduced, and environmental protection is achieved better. Two outer ends of the two telescopic outer tubes (2) are provided with inward arc-shaped chamfers, and either one of the two ends can be used for sucking, thereby achieving higher safety during sucking of a user.
