[0002] A video laryngoscope is a device used to take photos or videos of the larynx. It is generally composed of three parts: a display screen, a mounting base, and a throat inlet tube. When in use, the display screen is first installed on the mounting base, and then the throat inlet tube is inserted into the throat. The image captured by the end will be displayed on the display screen for diagnosis of the larynx.

[0003] Personnel need to regularly remove the display screen from the mounting base for disinfection and maintenance. During this step, the connector on the back of the display screen needs to be pulled out from the mounting base. The connector and the mounting base are generally fixedly installed by means of a lock. The traditional lock structure is firstly small in size, and it is not easy for personnel to open and close the lock when installing and removing the display screen, and the installation and removal speed is slow. Secondly, the connection between the connector and the mounting base is not stable enough only by using the lock. Therefore, it is necessary to design a new visual laryngoscope connector quick installation and removal lock device to solve this problem. Utility Model Content
