According to the structure, in the pre-emitting state, the elastic clamping arm deforms under the action of the convex part, the elastic clamping arm fixes the indwelling unit, and when the protective sleeve and the release paper are removed, the patch type indwelling unit cannot be separated from the puncture unit; at the puncture position, the elastic clamping arm is separated from the convex part and recovers to the initial state, and the elastic clamping arm and the indwelling unit are detached, so that the puncture unit and the patch type indwelling unit can be separated more easily without stretching skin through the patch type indwelling unit.
