[0002] With the rapid pace of modern life and parents' increasing emphasis on children's safety and comfort, baby carrycots and the strollers used in conjunction with them have become indispensable equipment in daily life. In the prior art, baby carrycots are usually connected to strollers through fixing devices or hook mechanisms. Although these traditional connection methods ensure a certain degree of connection stability, there are many inconveniences in actual operation. For example, when it is necessary to remove the carrycot from the stroller, parents need to operate the unlocking mechanism and support the weight of the carrycot simultaneously, which is particularly difficult for parents with less strength or those who are holding a baby and operating with one hand. Therefore, it is particularly important to design a quick-release mechanism that can be operated with one hand. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a quick-release mechanism for a carrycot stroller with a display function. A locking slider is added to the locking hook of the existing connector between the carrycot and the stroller, and the unlocking state of the locking hook is locked by the locking slider, so as to facilitate separating the carrycot from the stroller with one hand.

[0004] To solve the above technical problems, the utility model provides a quick-release mechanism for a carrycot stroller with a display function, which realizes quick locking or unlocking between the carrycot and the stroller connector.
