The two mounting frames 316 are fixedly connected to the connecting frames 314, respectively. The inner walls of the two mounting frames 316 are slidably connected with fixing blocks 323, and the fixing blocks 323 have the same structure as the blocking block 210. The ends of the two fixing blocks 323 are provided with fixing grooves 324, and the outer walls of the two mounting frames 316 are fixedly connected with two support rods 325, and the ends of the two support rods 325 pass through the fixing blocks 323 and are slidably connected thereto. The outer walls of the two support rods 325 are sleeved with third springs 326, and the ends of the two support rods 325 are fixedly connected with end covers 327, one end of the third spring 326 is fixedly connected to the end cover 327, and the other end of the third spring 326 is fixedly connected to the fixing block 323.

[0047] Two guide rods 318 are slidably connected to the inner walls of the two connecting frames 314, and the ends of the two guide rods 318 are fixedly connected to the second support blocks 317, and the ends of the second support blocks 317 are respectively fixedly connected to the second mounting sleeves 301.

[0049] Working principle: Place the shaken blood bag between two adjacent first limit strips 105 on the first conveyor belt 103, and place the blood bag where the blood needs to be drawn between two second limit strips 107 on the second conveyor belt 106. The electric roller 102 drives the first conveyor belt 103 and the second conveyor belt 106 to rotate at the same time, so as to transport the blood bag;

[0050] When the blood bag is transported to the bottom of the pressing plate 112, the first conveyor belt 103 and the second conveyor belt 106 stop rotating, and the first cylinder 111 pushes the pressing plate 112 to move downward, and the pressing plate 112 is pressed tightly on the two adjacent first limiting strips 105, and the blood bag braid is fixed up, down, left, and right by the pressing plate 112 and the two adjacent first limiting strips 105;

[0051] The injection needle is continuously fed to the second groove 306 through the feed port 304, and the second ring 305 is driven to rotate by the motor 109 below. At this time, the injection needle rotates downward along the inner wall of the second mounting sleeve 301. When the injection needle moves to the position of the connecting groove 302 below, the motor 109 below stops, and the injection needle is pressed against the fixed block 323. The fixed block 323 drives the clamping sleeve 322 to move through the extension frame 320. Under the elastic force of the third spring 326, the fixed block 323 fixes the injection needle through the fixed groove 324, and the clamping sleeve 322 is clamped between the finger hook part and the piston handle on the injection needle.

[0052] The first electric push rod 313 at the bottom pushes the connecting frame 314 to drive the installation frame 316 to move. At this time, the fixed block 323 pushes the injection needle tube to slide along the second ball 307 in the second groove 306, so that the injection needle tube is inserted into the blood bag. The fixed block 323 squeezes the injection needle tube. Under the friction between the fixed block 323 and the injection needle tube, the fixed block 323 stops moving, the sleeve 322 is stuck on the piston handle, and the second electric push rod 321 pulls the injection needle tube piston handle to move through the sleeve 322, so that blood can be drawn from the blood bag. The first electric push rod 313 drives the installation frame 316 to move in the opposite direction, so that the injection needle tube slides into the second groove 306 again, and the motor 109 at the bottom drives the injection needle tube to continue to rotate, so that the injection needle tube is separated from the fixed block 323, and the first conveyor belt 103 and the second conveyor belt 106 continue to rotate.

[0053] When the injection needle is rotated to the upper connection groove 302, the lower motor 109 stops, and the upper fixing block 323 fixes the injection needle again, and the blood storage test tube for detection is placed in the first groove 206. The upper motor 109 drives the first ring 205 to rotate. When the test tube is rotated to the mounting hole 204, the upper motor 109 stops, and the test tube squeezes the clamping block 210. Under the elastic force of the first spring 213, the clamping block 210 fixes the test tube. The second electric push rod 321 pulls the injection needle piston handle through the clamping sleeve 322 to move, so that the injection needle is inserted into the blood storage test tube. The second cylinder 310 squeezes the injection needle piston handle by pushing the squeezing block 311, and the blood inside the injection needle is injected into the blood storage test tube, completing the blood extraction.

[0054] When the injection needle rotates to the discharge hole 303 after injection, it will fall from the discharge hole 303 and be collected together. When the blood storage test tube rotates to the discharge port 203, it will fall from the discharge port 203, so that the blood storage test tubes can be collected together.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
