the lug is embedded into the first concave area to fix the piston when the piston is positioned at the end part of the needle tube far away from the sealing film; the projection is embedded into the second concave area after the piston is pushed by the connecting plate to move towards the sealing film until the sealing film is pushed to drop.
3. The automatic HIV-detecting lancing workstation according to claim 2, wherein the lancing detector further comprises a first telescoping mechanism and a second telescoping mechanism, the first telescoping mechanism being configured to move the connecting shaft such that the connecting shaft resets under the restoring force of the spring after the needle pierces the sealing membrane and pierces the finger; the second telescopic mechanism is used for moving the connecting shaft to enable the protruding block of the piston to be embedded into the second concave area so as to drop the detected blood sample in the needle tube onto the ELISA plate.
4. The automatic HIV-detecting lancing workstation according to claim 3, wherein the finger rest mechanism further comprises a trigger switch, the trigger switch is located on the rotating wheel, and when a finger is placed on the bracket, the trigger switch is triggered under the action of the pressing of the finger, so that the conveyor belt drives the lancet to move to the lancing window for lancing.
5. The automated HIV-detecting lancing workstation of claim 4, wherein the disinfection probe comprises a cotton ball probe comprising a hollow probe tube connected to a storage box containing an iodophor cotton ball, the iodophor cotton ball being guided from the storage box through the probe tube, and further comprising an alcohol spray head comprising a spout and an alcohol pot connected to the spout, the spout spraying a predetermined amount of alcohol as the spout extends out of the housing.
6. The automatic HIV-detecting lancing workstation according to claim 5, wherein the lancing device further comprises a recovery barrel disposed in the second inner case, the recovery barrel is disposed below the conveyor belt, the conveyor belt moves to position the lancet above the recovery barrel after the lancet drops into the elisa plate, the second telescoping mechanism releases the connecting shaft, and the connecting shaft pushes the connecting plate under the action of the spring until the connecting plate is separated from the piston, so that the lancet drops into the recovery barrel.
7. The automatic HIV-detecting lancing workstation according to claim 6, wherein the lancing detector further comprises a touch screen provided on the housing for displaying a current detection state and an input command, and the lancing chamber comprises a coded lock for opening a door of the lancing chamber when the coded lock passes the received identity information from the mobile terminal, the touch screen displaying the identity information and mapping the detection result obtained by the result reading means to the identity information.
8. The automatic HIV-detecting lancing workstation according to claim 7, wherein an ultraviolet light lamp is provided in the lancing chamber for hermetically sterilizing the lancing chamber.
