[0033] Working principle:
[0034] Firstly, during the medical test, the liquids in the test tube bodies 5 need to be extracted for experimental detection, the test tube bodies 5 to be detected are placed in the connecting shell 3, at this time, the connecting handle 10 is rotated to drive the rotating rod 37 fixedly connected with the connecting handle 10 to rotate, the threaded rod two 31 is rotatably connected in the supporting bottom plate 1, the surfaces of the threaded rod two 31 and the rotating rod 37 are fixedly provided with bevel gears 36, the rotating rod 37 drives the two bevel gears 36 to mesh with each other during rotation, at this time, the threaded rod two 31 rotates, the connecting block four 33 threadedly connected with the threaded rod two 31 moves up and down during rotation, the connecting block four 33 drives the protective shell 2 fixedly connected with the connecting block four 33 to move during movement, at this time, the adjustment of the distance between the group of needle cylinder tubes 6 and the group of test tube bodies 5 is completed, the practicability is improved, the left and right sides of the protective shell 2 are fixedly provided with the T-shaped blocks two 35 and movably connected with the two connecting plates 11 to ensure the stability during movement, the nut 28 is unscrewed to open the limiting of the threaded rod one 27 and the connecting block three 26, the connecting block three 26 is fixedly connected with the fixed plate 25 in front, the fixed plate 25 is fixedly connected with the two pairs of needle cylinder tubes 6, the group of needle cylinder tubes 6 can be taken off by opening the limiting, and the detachable design is convenient for subsequent maintenance and cleaning.
[0035] The second step, the connecting shell 3 is movably connected with the support base plate 1 through the two T-shaped blocks 20 fixed thereon. When a group of test tube bodies 5 need to be cleaned, first, add appropriate amount of water and cleaning agent into the test tube body 5, pull the handle block 23 upward to drive the limiting block 22 fixed thereto to move, so that the limiting block 22 is disengaged from the limiting groove 29 formed in the support base plate 1, and the spring 24 is compressed. At this time, the connecting shell 3 is opened and can be moved. After moving forward to the top end, the spring 24 drives the limiting block 22 to reset. At this time, the support base plate 1 and the connecting shell 3 are in a limiting and fixed state. At this time, the connecting shell 3 is connected with the connecting rod 7 through the connecting block two 15 fixed thereon, and is connected with the two stop blocks 13. Then, the connecting block two 15 and the connecting rod 7 are limited and fixed by the bolts 12. In the process of installing the connecting shell 3, the two pairs of cleaning brushes 19 arranged below the connecting shell 3 are sleeved into a group of test tube bodies 5 and are in contact with the inner walls thereof. At this time, the motor 8 is started, and the output shaft drives the connecting shaft 16 to rotate. In the process of rotating, the connecting shaft 16 drives the rack gear 17 fixed thereto to rotate. In the process of rotating, the belt 18 is in contact with the rack of the rack gear 17 and is driven to move. The moving belt 18 transmits power to other rack gears 17. The driven rack gears 17 also start to rotate. At this time, the connecting shafts 16 fixed to the rack gears 17 also start to rotate. In the process of rotating, the two pairs of cleaning brushes 19 fixed below the connecting shafts 16 also start to rotate. In the process of rotating, the cleaning brushes 19 clean the inner walls of the test tube bodies 5. Through the structure, the cleaning efficiency is effectively improved, the accumulated substances in the test tube bodies 5 are reduced, the service life of the device is prolonged, the labor intensity is reduced, and the maintenance cost is reduced.
[0036] The third step, the protective shell 2 drives the group of needle cylinder tubes 6 arranged therein to move in the process of moving. After adjusting the group of needle cylinder tubes 6 to the required height, the needle heads arranged thereon are in contact with the liquids in the two pairs of test tube bodies 5. Pulling the piston on the needle cylinder tube 6 extracts the liquid. The surface of the group of needle cylinder tubes 6 is provided with a scale table to extract an appropriate amount of liquid. Different detection items require different amounts of samples. By arranging the two pairs of needle cylinder tubes 6, different amounts of liquid samples can be extracted flexibly to meet the requirements of various experiments or detection. In addition, arranging the group of needle cylinder tubes 6 can reduce the number of times of replacing the needle heads of the operator in the process of experiment or detection, save time, and improve the operation efficiency. Especially when a plurality of detection needs to be continuously performed, it is more remarkable.
