When the receiving frame 9 is driven to shake by the pull rod 21, the clamping block 22 slides inside the slide groove to increase the stability of the receiving frame 9 during reciprocating motion. The slide groove will support the clamping block 22 to ensure that the receiving frame 9 moves along a parallel line to prevent the receiving frame 9 from tipping over inside the collecting box 1, and when the receiving frame 9 reciprocates, the second spring 23 is squeezed and stretched. The expansion and contraction energy storage of the second spring 23 will buffer the kinetic force generated by the reciprocating motion of the receiving frame 9.

[0037] For further information, see Figure 2 and Figure 5In this embodiment, a support plate 25 is installed below the fixing frame 10, and a fixing plate 26 is fixedly connected between the fixing frame 10 and the supporting plate 25. A sliding groove is provided inside the fixing plate 26, and a sliding sleeve is slidably connected inside the sliding groove. A linkage rod 27 is rotatably connected to the sliding sleeve. A guide seat is fixedly connected between the fixing frame 10 and the support plate 25 and on a side away from the fixing plate 26. The linkage rod 27 extends to the inside of the guide seat away from the side of the fixing plate 26. Two groups of linkage rods 27 are provided, and the two groups of linkage rods 27 are arranged in a cross-shaped structure. The supporting plate 25 is designed with engaging grooves 28 symmetrically provided at both ends. In order to adapt to test tubes of different heights, the fixing frame 10 is lifted upward to adjust the angle of the linkage rod 27. Then the sliding sleeve slides inside the fixing plate 26 to realize the vertical rise of the fixing frame 10. Then the fixing frame 10 and the supporting plate 25 move away from each other, so that the distance between the two is extended. Then the test tube is inserted into the extrusion sheet 12. After being fixed, the test tube will support the fixing frame 10 and the supporting plate 25 to prevent the fixing frame 10 from falling.

[0038] For further information, see Figure 5 , Figure 6 and Figure 7 In this embodiment, the top of the support plate 25 is fixed and is fixedly connected to a cylinder 29 directly below the extrusion sheet 12. A pressure plate 30 is slidably connected to the middle of the cylinder 29. An extension plate 31 is fixedly connected to the outside of the cylinder 29. A limiting groove 32 is provided inside the cylinder 29 and the extension plate 31. An extrusion rod 33 is rotatably connected inside the limiting groove 32. A clamping block 34 is fixedly connected to the top of the extrusion rod 33. The clamping block 34 is designed in a semi-arc structure. When the test tube is fully inserted into the extrusion sheet 12, its bottom will directly fit into the cylinder 29. Then, the bottom of the test tube squeezes the pressure plate 30, so that the pressure plate 30 is pressed down inside the cylinder 29. Then, one end of the extrusion rod 33 is squeezed, so that the extrusion rod 33 rotates and approaches each other. Then, the clamping block 34 fits with the bottom end of the test tube to complete the positioning.

[0039] For further information, see Figure 5 , Figure 6 and Figure 7 In this embodiment, a soft pad is fixedly connected to the top of the pressure plate 30, and a third spring 35 is fixedly connected to the bottom of the pressure plate 30. The end of the third spring 35 away from the pressure plate 30 is fixedly connected to the connecting plate 36. The squeezing rod 33 extends between the pressure plate 30 and the connecting plate 36. The soft pad designed on the top of the pressure plate 30 will protect the bottom of the test tube. When the pressure plate 30 is pressed down, the third spring 35 will be squeezed. When the test tube is pulled out, the third spring 35 drives the pressure plate 30 to reset and releases the squeezing of the squeezing rod 33.

[0040] For further information, see Figure 8 In this embodiment, the bottom end of the inner side of the receiving frame 9 is rotatably connected to a gear 38, the outer side of the gear 38 is symmetrically meshed with a rack 39, the outer side of the rack 39 is slidably connected to a limit plate 40, the bottom of the limit plate 40 is fixedly connected to a column, the side away from the rack 39 is fixedly connected to a baffle 41, the side away from the baffle 41 is fixedly connected to a flat plate 42, the top of the baffle 41 is fixedly connected to a position corresponding to the engaging groove 28, and the end of the rack 39 close to the baffle 41 is fixedly connected to a fourth spring 44. By connecting one end of the support plate 25 with the baffle 41 The locking groove 28 will directly fit into the outside of the locking block 43, and the support plate 25 will squeeze the baffle 41 to stretch the fourth spring 44. At the same time, the rack 39 will move with the baffle 41, and the gear 38 will rotate to move another group of baffles 41. Then the two groups of baffles 41 will move away from each other, and the other side of the support plate 25 will be placed on the other group of baffles 41. The support plate 25 will be supported by the flat plate 42. When the support plate 25 is completely in contact with the baffle 41, the fourth spring 44 will be reset to complete the fixation of the support plate 25 inside the receiving frame 9.

[0041] In this embodiment, the implementation scenario is specifically as follows: by fitting one end of the support plate 25 with the baffle plate 41, the locking groove 28 will be directly locked into the outside of the locking block 43, and the support plate 25 will squeeze the baffle plate 41 to achieve the stretching of the fourth spring 44, and the rack 39 will follow the movement of the baffle plate 41, and the gear 38 will be rotated to achieve the movement of the other group of baffle plates 41, and then the two groups of baffle plates 41 will move away from each other, and then the other side of the support plate 25 will be placed on the other group of baffle plates 41, and the support plate 25 will be supported by the flat plate 42. When the support plate 25 is completely in contact with the baffle plate 41, the fourth spring 44 will be reset to complete the fixation of the support plate 25 inside the receiving frame 9, and the outside of the fixing frame 10 will be wrapped by the receiving frame 9 to prevent it from being externally The force impact causes the test tube to rupture, resulting in the destruction of the collected blood sample. In order to adapt to test tubes of different heights, the fixing frame 10 is lifted upward to adjust the angle of the linkage rod 27, and then the sliding sleeve slides inside the fixing plate 26 to realize the vertical rise of the fixing frame 10, and then the fixing frame 10 and the support plate 25 move away from each other, so that the distance between the two is extended, and then the test tube is inserted into the inside of the extrusion sheet 12, and then the first spring contracts to realize the extrusion sheets 12 moving away from each other and adapting to the diameter of the test tube, and then the expansion and contraction energy of the first spring is released, and the extrusion sheet 12 is firmly fitted with the test tube to complete the fixation of the test tube. After the test tube is fixed, it will support the fixing frame 10 and the support plate 25 to prevent the fixing. The rack 10 descends, and when the test tube is fully inserted into the extrusion sheet 12, its bottom will be directly stuck into the cylinder 29, and then the bottom of the test tube will squeeze the pressure plate 30, so that the pressure plate 30 is pressed down inside the cylinder 29, and then one end of the extrusion rod 33 is squeezed, so that the extrusion rod 33 rotates and approaches each other, and then the clamping block 34 fits with the bottom end of the test tube to complete the positioning, and the guide plate 13 is rotated by the motor, and then the positioning column 14 will rotate at the eccentric position of the guide plate 13 and squeeze the waist groove 16. When the positioning column 14 moves to the top and bottom of the waist groove 16 respectively, the swing rod 15 will swing along the insertion axis, and the tooth plate 17 will follow the swing rod 15 to move synchronously, and will directly engage with the tooth groove 20 The connecting rods 19 are meshed with each other to generate a kinetic force for the connecting column 19, and the collar 18 limits the connecting column 19 so that the connecting column 19 can slide back and forth inside the collar 18. At the same time, the limiting sleeve blocks the two ends of the connecting column 19 to prevent the connecting column 19 from sliding out of the collar 18. At the same time, the pull rod 21 will move with the connecting column 19, thereby driving the receiving frame 9 to shake inside the receiving groove 5, so as to shake the blood collected inside the test tube and prevent the blood from coagulating, resulting in data deviation. When the receiving frame 9 is driven to shake by the pull rod 21, the clamping block 22 slides inside the slide groove at the same time, increasing the stability of the receiving frame 9 during reciprocating motion. The slide groove will support the clamping block 22 to ensure that the receiving frame 9 moves along a parallel line.Prevent the receiving frame 9 from tipping over inside the collecting box 1, and when the receiving frame 9 reciprocates, it squeezes and stretches the second spring 23. The expansion and contraction energy storage of the second spring 23 will buffer the kinetic force generated by the reciprocating motion of the receiving frame 9, and then buckle the lid 2, rotate the hook 7, and fit it with the clamp ring 8, so that the lid 2 and the collecting box 1 become a closed space. At the same time, the refrigeration sheet 6 will release cold air, so that the internal space of the collecting box 1 is in a suitable temperature state, which is convenient for preserving the blood inside the test tube. Then, the handle 3 is adjusted from the inside of the groove to facilitate carrying the collecting box 1.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
