[0002] A respirator is composed of an air supply source and a respirator. It can supply oxygen to the user in an environment with low oxygen. It is mostly used for safe and effective firefighting or rescue work in various environments such as thick smoke, toxic gas, steam or hypoxia. There are many kinds of existing respirators, among which long-tube respirators have the widest range of uses and high flexibility. Generally, an oxygen cylinder is connected to a long tube, and the long tube can be retracted and released. Generally, the long tube is rolled up on a reel and released when needed to achieve a wide range of uses. It can be reeled up after use. However, this structure is not convenient for releasing and rewinding the long tube when in use. The long tube needs to be released in advance and cannot be released directly by pulling the long tube. The long tube cannot be rolled up evenly, which makes the long tube pile up and be compressed, and is easily damaged. Therefore, it is necessary to improve the convenience and flexibility of retracting and releasing the long tube to avoid damage to the long tube.
