The invention provides a water mirror fixing device. The water mirror fixing device is used for connecting a water mirror and a breathing tube, the water mirror is provided with a head band and a fixing ring, and the head band is movably arranged in the fixing ring in a penetrating mode. The water mirror fixing device comprises a positive fixing element and a negative fixing element connected with the positive fixing element. Wherein the positive fixing element is connected with one of the fixing ring and the breathing tube, and the negative fixing element is connected with the other one of the fixing ring and the breathing tube. Therefore, a user can easily combine or disassemble the water mirror and the breathing tube, and the water mirror and the breathing tube cannot generate linear relative displacement due to external force in a use state.
本发明提出一种水镜固定装置。水镜固定装置用于连接一水镜与一呼吸管,水镜具有一头带与一固定环,该头带活动穿设于该固定环中。水镜固定装置包含一阳性固定元件以及与阳性固定元件相连接的一阴性固定元件。其中,阳性固定元件与固定环及呼吸管的其中之一连接,阴性固定元件与其中的另一连接。由此,使用者可轻易结合或拆卸水镜与呼吸管,且水镜与呼吸管在使用状态下不会因外力而产生线性相对位移。
