In the preferred embodiment of the present invention, the coupling surface of the second buckle 1033 and the first buckle 1012 is a plane, which forms a fixed angle with the horizontal plane, and the extension end m2 of the plane converges at the proximal end.
With reference to fig. 11, the structure can push the first catch 1012 outward from the housing 101 when the second catch 1033 moves proximally relative to the first catch 1012, so as to release the coupling state between the first catch 1012 and the second catch 1033.
In the embodiment of the present invention, the first elastic element 1071 is in a compressed state and has elastic potential energy, and its own elastic force gives the parallel module slider 103 a pushing force Fr towards the proximal end, the pushing force Fr acts on the first buckle 1012 through the coupling surface of the second buckle 1033 and the first buckle 1012, and generates a component force Fsin perpendicular to the plane of the first buckle 1012, and the component force Fsin can push the first buckle 1012 towards the outside of the housing 101 to bend or bend, thereby releasing the coupling state of the first buckle 1012 and the second buckle 1033.
In the embodiment of the present invention, when the mounting unit 100 is used, the outer cover 1021 is rotated to break the column 10211, the protective cover 102 is separated from the housing 101, the proximal end of the mounting unit 100 is close to the skin of the user until the outer ring 1063 of the trigger module 106 is attached to the skin surface, the user presses the housing 101 at the distal end, the housing 101 moves towards the skin, the trigger module 106 remains stationary, so the trigger module 106 moves distally relative to the housing 101, the tab 1062 is separated from the first slot 10141 and enters the second slot 10142, meanwhile, the fixing catch 1061 is no longer in contact with the first catch 1012, the first catch 1012 bends or bends towards the outside of the housing 101 due to the component force Fsin, and the coupling state between the first catch 1012 and the second catch 1033 is released.
In the embodiment of the present invention, after the coupled state is released, the parallel slider module 103 continues to move proximally under the pushing of the first elastic element 1071, and simultaneously drives the analyte detection device 104 to move proximally until the lower outer housing 10413 of the analyte detection device 104 contacts with the skin surface of the user.
Referring to fig. 10c, in the embodiment of the present invention, the slider latch 10321 is in a latch connection with the sub-needle slider 10511, and the first elastic member 1071 pushes the parallel slider module 103 to move proximally, so as to drive the sub-needle module 105 to move proximally together.

The pushing force of the second elastic element 1072 on the auxiliary needle slider 10511 is directed to the distal end, so that the auxiliary needle slider 10511 can push the slider catch 10321 away from the housing 101, and the slider catch 10321 is bent or bent, which is the same principle as fig. 11.
In the embodiment of the present invention, in the mounting unit 100, the side wall of the auxiliary needle limiting groove 1015 prevents the slider catch 10321 from bending or curving, and the state of the catch connection between the slider catch 10321 and the auxiliary needle slider 10511 does not change. As the parallel slider module 103 and the auxiliary needle module 105 move towards the proximal end until the slider catch 10321 is separated from the auxiliary needle limiting groove 1015, the inner wall of the auxiliary needle limiting groove 1015 no longer prevents the slider catch 10321 from bending or bending, the second elastic element 1072 pushes the auxiliary needle slider 10511 towards the distal end, meanwhile, the auxiliary needle slider 10511 pushes the slider catch 10321 to bend or bend towards the outside, the catch connection between the slider catch 10321 and the auxiliary needle slider 10511 is released, the second elastic element 1072 continues to push the auxiliary needle slider 10511 to move towards the distal end, finally, the auxiliary needle module 105 returns to the initial position, and the auxiliary needle 1052 is retracted into the housing 101, so as to prevent the auxiliary needle 1052 from being exposed outside the housing 101, and avoid causing unnecessary injuries.
In the embodiment of the invention, when the slider fastener 10321 is separated from the auxiliary needle limiting groove 1015, the half-surrounding needle body 10522 of the auxiliary needle is punctured into the subcutaneous part of the user.
In the embodiment of the present invention, in the mounting unit 100, the T-shaped slider 10351 is located in the limiting groove 1013, and the limiting groove 1013 limits the position and the direction of the parallel slider module 103 through the T-shaped slider 10351 to ensure that the parallel slider module 103 is perpendicular to the sliding direction thereof, so that the analyte detection device 104 disposed at the front end of the parallel slider module 103 is perpendicular to the moving direction thereof, and the auxiliary needle 1052 is parallel to the moving direction thereof, so that the auxiliary needle 1052 and the internal part of the sensor wrapped by the auxiliary needle 1052 can be inserted under the skin of the user at a perpendicular angle, thereby alleviating the pain of the user.
In the embodiment of the present invention, during the process of sliding the parallel slider module 103 to the proximal end, the T-shaped slider 10351 slides in the limiting groove 1013 until contacting the outer ring 1063 of the trigger module 106, the parallel slider module 103 continues to move to the proximal end under the pushing of the first elastic element 1071, and the outer ring 1063 blocks the T-shaped slider 10351 to continue to move to the proximal end, so that the T-shaped slider 10351 bends or bends around the vertical portion, the T-shaped latch 10352 is released from the latching connection with the latching hole 10412, and the analyte detection device 104 is separated from the parallel slider module 103, and thus can be installed on the skin surface of the user.
In the embodiment of the present invention, when the T-shaped slider 10351 contacts the outer ring 1063, the position of the parallel slider module 103 is a predetermined position, and at this time, the lower outer housing 10413 of the analyte detection apparatus contacts the skin surface of the user.

During the proximal movement of the parallel slider module 103 and the sub-needle module 105, the semi-enclosed needle 10522 carrying the sensor 1042 penetrates into the skin, after the sub-needle 1052 is retracted, the inner part of the sensor 1042 remains under the skin, and the retraction of the needle does not affect the inner part of the sensor 1042.
In an embodiment of the present invention, when performing the mounting action, the user is required to press the housing 101 at the distal end, apply a force F to the housing 101 in a proximal direction, the outer ring 1063 of the trigger module 106 contacts the skin surface of the user, and the skin of the user imparts a force F' to the outer ring 1063 opposite to the force F, thereby effecting relative movement of the trigger module 106 and the housing 101. During actual installation, the absolute position of the trigger module 106 remains unchanged and the housing 101 moves proximally.
Before the installation operation is performed, in order to prevent the trigger module 106 from moving relative to the housing 101, the protective cover 102 is installed at the proximal end of the housing 101, and the protective cover 102 surrounds the outer ring 1063 of the trigger module, so that the installation operation can be prevented from being performed at an incorrect position due to the outer ring 1063 being touched by mistake, and the trigger prevention function is performed.
In an embodiment of the present invention, an adhesive patch (not shown) is further disposed on the lower outer housing 10413 of the analyte detection device for fixing the analyte detection device 104 to the skin surface of the user.
