[0043] The limit block 309 also includes a clamp block 3091, the bottom end of the clamp block 3091 is fixedly connected to a sealing cover 3092, the upper and lower ends of the clamp block 3091 are provided with clamp blocks 3095 adapted to the card slot 303, the clamp block 3091 is provided with a receiving groove, the receiving groove is provided with a second spring 3093 and a limit card strip 3094, the second spring 3093 is arranged below the limit card strip 3094 to elastically support the limit card strip 3094 upward, and the unfolded end of the disinfection cotton roll 304 is located at Between the fixed block 301 and the limiting block 309 and in contact with the fixed block 301, an easy-tear seam is arranged in the middle of the sterilized cotton roll 304, a through hole is opened in the middle of the fixed block 301, the top of the limiting card strip 3094 is an arc surface, a limiting column head 3096 is arranged on the limiting card strip 3094, the sterilized cotton roll 304 passes through the limiting card strip 3094, the limiting column head 3096 abuts against the sterilized cotton roll 304, and the side of the fixed box 302 close to the card slot 303 is sleeved with the sealing cover 3092.

[0044] It is worth noting that during installation, the clamping block 3091 is slid out of the card slot 303 by sliding the clamping block 3091, and the sealing cover 3092 does not contact the fixed box 302. The center of the sterilized cotton roll 304 is inserted into the fixed box 302, the limiting clamping strip 3094 is squeezed, and the sterilized cotton roll 304 is pulled through the limiting clamping strip 3094 and bonded to the connecting shaft 305. The limiting rod 306 is twisted to tighten the clockwork 307 to store power, and the connecting shaft 305 is inserted outside the limiting rod 306. The limiting block 309 is slidably installed on the fixed block 301, and the installation or replacement operation of the sterilized cotton roll 304 is completed. 2 and the sealing cover 3092 can seal and protect the disinfection cotton roll 304. By placing the finger between the fixed block 301 and the clamping block 3091 and pressing the disinfection cotton roll 304 with the fingertips, the disinfection cotton roll 304 is made to be close to the fixed block 301. By sliding downward along the pressing plate 201, the finger can be inserted between the fixed block 301 and the clamping block 3091, and at the same time, the finger can squeeze the limiting card strip 3094, so that the second spring 3093 is compressed, and the limiting card strip 3094 is not engaged with the disinfection cotton roll 304, so that the lower end of the disinfection cotton roll 304 is unwound, and the finger can be wiped and disinfected in one direction upward.

[0045] like Figures 2 to 3 , Figure 5 and Figure 6 As shown, the pressing plate 201 is slidably connected to the analyzer body 1, the limiting groove 604 is a vortex structure, the fixing hole 605 passes through the second rotating wheel 602 and the aperture value is equal to the diameter value of the limiting column 402, the outer peripheral surface of the mounting cover 401 is provided with a rubber material and is sealed with the analyzer body 1, and a moving groove for limiting the sliding of the limiting column 402 is opened on one side of the mounting cover 401 close to the adjustment component 5;

When the second rotating wheel 602 rotates one circle, the limiting column 402 coincides with the fixed hole 605. The elastic force of the movable large cylinder 503 can push the movable cylinder 502 to extend quickly along the limiting cylinder 501. The movable cylinder 502 can push the first rotating wheel 601 to move toward the limiting component 4, so that the middle part of the second rotating wheel 602 is not engaged with the rotating rod 205, and the limiting column 402 passes through the second rotating wheel 602, and the blood collection needle 603 on the first rotating wheel 601 can be aligned with the blood collection port position, so that the device can continue the blood collection operation, making the device highly efficient.

[0048] The working process of the technical solution provided by the present invention is as follows:

[0049] First, the operator places his fingers between the fixed block 301 and the clamping block 3091 and presses the disinfection cotton roll 304 with the fingertips, so that the disinfection cotton roll 304 is close to the fixed block 301.

The finger can squeeze the limiting strip 3094, so that the second spring 3093 is compressed, and the limiting strip 3094 does not engage with the disinfection cotton roll 304, so that the lower end of the disinfection cotton roll 304 is unwound, and the finger can be wiped and disinfected in one direction upward.

[0050] By sliding the disinfection component 3 to the blood collection port of the pressing component 2 and pressing it, the first spring 206 is stretched, so that the blood collection needle 603 can pass through the blood collection port, and pierce the easy-tear edge of the disinfection cotton roll 304 and then prick the finger for blood collection, and the pressing plate 201 drives the movable ratchet 203 to move toward the inside of the analyzer body 1, and the movable ratchet 203 can rotate and abut against the gear 204. When the pressing plate 201 is released, the elastic force of the first spring 206 can pull the movable ratchet 203 to reset, the pressing plate 201 can pull the movable ratchet 203, the baffle 202 can limit the movable ratchet 203, the movable ratchet 203 can abut against the gear 204 and drive it to rotate, and the gear 204 can drive the blood collection component 6 to rotate through the rotating rod 205, so that the next blood collection needle 603 can be aligned with the blood collection port.

[0051] By loosening it upwards with fingers and taking it out from the fixed block 301, the elastic force of the second spring 3093 can reset the limiting clamping strip 3094 and clamp the sterilized cotton roll 304, so that the sterilized cotton roll 304 can no longer be unwound. By resetting the fixed block 301 upwards, the elastic force of the spring 307 can drive the connecting shaft 305 to rotate through the limiting rod 306, so that the sterilized cotton roll 304 that has been unfolded can be wound and collected by the connecting shaft 305.

[0052] The second rotating wheel 602 is driven to rotate by the rotating rod 205, and the limiting column 402 can slide along the limiting groove 604. The limiting column 402 can press the blood collection component 6, so that the adjustment component 5 is in a compressed state. When the second rotating wheel 602 rotates one circle, the limiting column 402 coincides with the fixed hole 605. The elastic force of the movable large cylinder 503 can push the movable cylinder 502 to extend quickly along the limiting cylinder 501. The movable cylinder 502 can push the first rotating wheel 601 to move toward the limiting component 4, so that the middle part of the second rotating wheel 602 is not engaged with the rotating rod 205, and the limiting column 402 passes through the second rotating wheel 602, and the blood collection needle 603 on the first rotating wheel 601 can be aligned with the blood collection port position to complete the operation.
