[0002] At present, the emergency stop button is an important guarantee for all kinds of automation equipment, which is used to stop the machine in an emergency when an unexpected situation occurs. The emergency stop button uses a pressing method to press down the button rod, so that the button rod triggers the contact component to play the role of emergency stop, and the positioning setting of the stop / reset secondary gear is realized by the cooperation of the positioning ball and the positioning groove, such as the "An emergency stop button operating mechanism for a flameproof control box" disclosed in Chinese patent CN203690170U, but it lacks idle travel and is prone to false triggering when used.

[0003] At the same time, it is found in actual applications that the emergency stop button needs to have a certain waterproof performance due to the needs of the application occasions. For example, the "an emergency stop button" disclosed in China CN202220421199.5 achieves a sealing effect on the mushroom head (translucent cap) through a sealing ring, but the tail connection is connected by a connecting piece (its Figure 1 and Figure 3 As shown in the figure), there is a certain risk of water leakage in subsequent use. Therefore, an emergency stop button that can solve the above problems is urgently needed. Summary of the invention
