Before the sensor base assembly 4 reaches the skin of the recipient, the limiting ribs 72 release the limit of the third elastic buckle 13 of the base 2, i.e. the bracket 1 and the base 2 are unlocked. The sensor base assembly 4 and the leading-in needle 6 are driven by the base 2 to reach the skin of a receptor by the elastic piece 5, and the sensor in the leading-in needle 6 is inserted in place; the support 1 continues to move under the action of the elastic element 5, and the third elastic buckle 13 is disengaged from the groove 22.
