The fixed body 11 has an internal cylindrical structure to accommodate the other end of the test tube holder 2, the guide block 32, and the movable assembly 33. A pressing through hole 008 is provided in the center of the test tube holder 2 for one end of the pressing column 31 to pass through. Press the through hole 008, and make one end of the pressing column 31 compressibly connected to the compression component 12; the other end of the test tube holder 2 has a cylindrical structure, and the outer side of the other end of the test tube holder 2 is rotatably connected to the fixed body 11. The positioning pin 002 supports the test tube holder 2 while allowing the positioning pin 002 to slide circumferentially around the other end of the test tube holder 2; the guide block 32 has an L-shaped structure, one end of the guide block 32 is fixedly connected to one end of the pressing column 31, and the other end of the guide block 32 is compressibly movably connected to one end of the movable component 33. The other end is slidably connected to the outer side of the middle of the other end of the test tube holder 2, so that when the pressing column 31 is pressed, the pressing column 31 compresses the compression assembly 12 and moves downward, causing the guide block 32 to move downward with the pressing column 31; the other end of the guide block 32 is compressibly connected to one end of the movable assembly 33, so that the movable assembly 33 moves downward with the guide block 32 in the second guide groove. When the movable assembly 33 moves down to the lowest point of the second guide groove 23, under the expansion action of the second spring 333 of the movable assembly 33, the movable assembly 33 enters the second guide groove 23, releasing the pressing column 31. Under the stretching force of the first spring 122, the movable component 33 slides upward along the first guide groove 22, causing the pressing column 31 to move upward together with the guide block 32, thereby driving the test tube holder 2 to rotate clockwise by a certain angle, transporting the No. 2 blood collection tube 4 to the position of the No. 1 blood collection tube 4, avoiding the omission of the No. 2 blood collection tube 4 or the disruption of the placement of the No. 2 blood collection tube 4; in summary, the test tube holder of this utility model for preventing missed blood collection is rotated to the position of the next blood collection tube by pressing the pressing column, avoiding the problem of blood collection errors caused by missing blood collection tubes or disrupting the order.

[0035] In some possible implementations, the compression assembly 12 includes: a fixing post 121, which is cylindrical in shape, with one end of the fixing post 121 fixedly connected to the fixing body 11; a first spring 122, which is sleeved around the fixing post 121, with one end of the first spring 122 abutting against the fixing body 121; wherein, one end of the pressing post 31 has a pressing fixing hole 003, which is sleeved on the other end of the fixing post 121, and one end of the pressing post 31 abuts against the other end of the first spring 122.

[0036] Specifically, the fixing post is fixed to the bottom of the fixing body, and the other end of the fixing post is embedded in the pressing fixing hole. The other end of the fixing post can slide in the pressing fixing hole. The first spring is sleeved around the fixing post, and one end of the pressing post abuts against the first spring, so that the pressing post squeezes the first spring and moves downward during the pressing process.

[0037] In some possible implementations, the other end of the test tube holder 2 has a cylindrical structure, and a plurality of first guide grooves 22 and a plurality of second guide grooves 23 are provided on the outer side of the middle of the other end of the test tube holder 2; the plurality of first guide grooves 22 are arranged at parallel intervals along the circumferential direction of the pressing through hole 008; the plurality of second guide grooves 23 are arranged at parallel intervals along the circumferential direction of the pressing through hole 008 and parallel to the central axis of the pressing through hole 008; each first guide groove 22 is arranged adjacent to each second guide groove 23; one end of each first guide groove 22 is connected to one end of an adjacent second guide groove 23, and each first guide groove... The other end of 22 is connected to the other end of the adjacent second guide groove 23 to form a guide movable groove. The other end of the movable component 33 is fitted and slidably connected to the guide movable groove. Each first guide groove 22 and each second guide groove 23 are smooth inclined grooves. The depth of one end of each first guide groove 22 is the same as the depth of one end of each second guide groove 23, and the depth of the other end of each first guide groove 22 is the same as the depth of the other end of each second guide groove 23. The shallow end of each first guide groove 22 is located above the deep end. A plurality of test tube grooves 21 are evenly spaced along the circumferential direction of the pressing through hole 008.

[0038] Specifically, the first guide groove is arranged parallel to the circumferential direction of the pressing through hole on the outer side of the other end of the test tube rack, and the first guide groove is set at a certain angle to the axial direction of the pressing through hole; the second guide groove is arranged parallel to the axial direction of the pressing through hole on the outer side of the other end of the test tube rack, and the second guide groove is parallel to the axial direction of the pressing through hole. The two ends of the first guide groove and the second guide groove are located on the same circumferential curve at the other end of the test tube rack; the first guide groove and the second guide groove are arranged adjacent to each other, and the two ends of the first guide groove are respectively connected to the adjacent second guide groove, so as to form a serrated guide groove along the pressing through hole; both the first guide groove and the second guide groove are smooth inclined grooves with shallow upper grooves and deep lower grooves. This causes the movable component to slide downwards in the second guide groove when the pressing column presses down on the first spring. When it slides to the bottom of the second guide groove, it enters the first guide groove under the action of the second spring. Then, the pressing column is released, causing the movable component to move upwards along the first guide groove under the action of the first spring. This causes the test tube holder to rotate clockwise by a certain angle, transporting the No. 2 blood collection tube to the position of the No. 1 blood collection tube, avoiding missing the No. 2 blood collection tube or messing up its placement. In summary, by pressing the pressing column, the movable component moves along the guide groove, causing the test tube holder to rotate clockwise, thus ensuring that the blood collection tubes are delivered to the blood collection operator in sequence, avoiding missing the blood collection tubes or messing up their placement.

[0039] In some possible implementations, the other end of the guide block 32 is provided with a movable hole 004, a rod through hole 005, and a spring receiving hole 006. The movable hole 004, the rod through hole 005, and the spring receiving hole 006 are sequentially connected and adjacent to each other. The diameters of the movable hole 004 and the spring receiving hole 006 are both larger than the diameter of the rod through hole 005. The movable component 33 includes: a fixing nut 331, which is located inside the movable hole 004; and a guide pin 332, the connecting end of which sequentially passes through the spring receiving hole. 006. The rod through hole 005 enters the movable hole 004, and the thin end of the guide pin 332 is fixedly connected to the fixing nut 331; the second spring 333 is located in the spring receiving hole 006 and is sleeved around the guide pin 332; one end of the second spring 333 abuts against the outer periphery of one end of the rod through hole 005, and the other end of the second spring 333 abuts against the thick end of the guide pin 332; wherein, the thick end of the guide pin 332 is slidably connected to the guide movable groove.

[0040] Specifically, the guide pin is thicker at one end and thinner at the other. The second spring is fitted onto the guide pin through the thinner end. Then, the thinner end of the guide pin passes through the spring receiving hole and the rod through hole in sequence into the movable hole. A fixing nut secures the thinner end of the guide pin within the movable hole, preventing the guide pin from detaching from the guide block. Simultaneously, both ends of the second spring abut against the outer periphery of the thicker end of the guide pin and the end of the rod through hole, respectively. The thicker end of the guide pin is slidably engaged with the guide groove. When the pressing column is pressed, the thicker end of the guide pin first moves downward within the second guide groove. The guide pin moves upward along the first guide groove when it reaches the bottom of the second guide groove and enters the first guide groove under the action of the second spring. The pressing column is released, and under the action of the first spring, the thick end of the guide pin moves upward along the first guide groove. Because the upper part of the first guide groove is shallow and the lower part is deep, the thin end of the guide pin slides in the movable hole during the upward movement. At the same time, the second spring is squeezed, so that the thick end of the guide pin stops moving when it reaches the top of the first guide groove. At this time, the test tube holder rotates clockwise by a certain angle, transporting the next blood collection tube to the position of the previous blood collection tube.

[0041] In some possible implementations, a positioning groove 24 is provided around the outer side of the other end of the test tube holder 2 along the circumferential direction of the pressing through hole 008, and the positioning groove 24 is located below the guide groove; wherein, a positioning groove 007 is provided on the side of the fixed body 11, the position of the positioning groove 007 is adapted to the position of the positioning groove 24, and one end of the positioning pin 002 passes through the positioning groove 007 and is engaged and movably connected with the positioning groove 24.

[0042] Specifically, the positioning pin passes through the positioning groove and engages with the positioning movable groove to support the test tube rack. At the same time, when the movable component moves in the guide movable groove and causes the test tube rack to rotate clockwise, the positioning movable groove rotates along with it, and one end of the positioning pin rotates relative to the positioning movable groove.

[0043] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
