[0028] The working principle of the utility model is as follows: during the use of the device, the user pricks blood with a finger and places it on the end of the guide block 10. The automatic clamping component 4 drives the two groups of colloidal gold detection strips 5 to clamp the finger, and the clamping block 6 squeezes the finger, so that the blood passes through the guide block 10 into the interior of the guide tube 11, then enters the interior of the two groups of guide grooves 8, and finally enters the detection groove 7 at the upper end of the two groups of colloidal gold detection strips 5, so as to perform detection.

[0029] It should be noted that, through the setting of the automatic clamping assembly 4, when the two groups of colloidal gold detection strips 5 need to be clamped, by pressing the control button, the output end of the control circuit board starting motor 42 drives the threaded rod 43 to move along the inside of the threaded seat 44, so that the threaded seat 44 drives the linkage rod 45 and the slide column 47 to move, so that the slide column 47 slides along the inside of the slide hole 48, and on the basis of the connection between the rotating shaft 410 and the rotating groove 411, the connecting rod 46 and the colloidal gold detection strip 5 are further driven to clamp relative to each other, and the support column 46 drives the connecting rod 46 to move relative to the colloidal gold detection strip 5. Under the support of 12 and the rotating hole 13, the two groups of colloidal gold detection strips 5 drive the clamping block 6 to clamp the finger. At the same time, the tension sensor 49 detects the clamping force. When the set value is reached, it is fed back to the control circuit board, and then the motor 42 is self-locked, and the operation of the output end of the motor 42 is stopped until the blood completely enters the interior of the detection groove 7. The output end of the motor 42 can be reversed by starting the control circuit board, and then the colloidal gold detection strip 5 is expanded outward, so that the finger is freed from the restraint. The operation is automated and there is no need for manual clamping, which saves time and effort.

[0030] It should be noted that through the setting of the disassembly component 3, when the colloidal gold test strip 5 needs to be replaced, the hand-held fixing bolt 33 is driven by the hand-held block to disengage from the inside of the fixing hole 32, so that the cover plate 2 can be taken out, and then the colloidal gold test strip 5 is taken out, so that the rotating hole 13 is separated from the outside of the support column 12, and the guide block 10 is taken out and replaced at the same time, without discarding the entire device, saving resources and being reusable.
