This invention provides a precise control structure and applicator for the indwelling device in a continuous glucose monitoring (CGM) meter. By incorporating a clock structure consisting of an unlocking control track and a control block, different areas on the unlocking control track apply varying forces to the control block. These forces switch precisely upon completion of the puncture, allowing the clock structure to correlate with the puncture process. This enables the device to sense the puncture and promptly unlock the indwelling device after the procedure. This mechanical structure offers precise control and high integration, making it a glucose monitoring product that provides accurate control within a relatively small size.
