Referring to fig. 1 to 4F of the drawings, a sample tube lifting device according to a preferred embodiment of the present invention is disclosed and illustrated in the following description, wherein the sample tube lifting device comprises a lifting frame 10 and a lifting unit 20 movably mounted to the lifting frame 10, the lifting unit 20 being configured to lift a sample tube 100 from a position to be lifted to a predetermined height.

Specifically, referring to fig. 1, the lifting frame 10 has a frame top end 11 and a frame bottom end 12 corresponding to the frame top end 11, and the height position of the frame top end 11 is higher than that of the frame bottom end 12, so that the lifting frame 10 extends along the height direction. Preferably, the lifting frame 10 may be vertically disposed. Alternatively, in other examples of the sample tube lifting device, the lifting frame 10 may be arranged obliquely.

Referring to fig. 1, 2A and 4, the lifting unit 20 includes a moving portion 21 and a lifting arm 22 disposed on the moving portion 21, wherein the moving portion 21 is movably mounted on the lifting frame 10, wherein the lifting arm 22 has an open end 221, a holding end 222 opposite to the open end 221, and a holding groove 223 extending from the open end 221 to the holding end 222, and wherein the sample tube 100 is allowed to slide into or out of the holding groove 223 of the lifting arm 22 at the open end 221 of the lifting arm 22. When the moving part 21 is driven to move along the lifting frame 10, the moving part 21 can drive the lifting arm 22 to synchronously move, so as to lift the sample tube 100 held in the holding groove 223 of the lifting arm 22.

Preferably, the lifting arm 22 has a substantially "U" shape, such that the lifting arm 22 can form the holding groove 223 with a single side opening. Specifically, the lift arm 22 further includes a connecting arm body 224 and two extending arm bodies 225, the two extending arm bodies 225 are respectively disposed at both ends of the connecting arm body 224, and the two extending arm bodies 225 are spaced apart from each other, so that the lift arm 22 forms the holding groove 223 between the two extending arm bodies 225. The diameter of the cap of the syringe 100 is larger than that of the body, and after the body of the syringe 100 slides into the holding groove 223 of the lifting arm 22, the opposite sides of the cap of the syringe 100 are overlapped on the upper surfaces of the two extending arm bodies 225 of the lifting arm 22, so as to hold the syringe 100 in the holding groove 223 of the lifting arm 22.

Preferably, the two extension arms 225 of the connecting arm 224 of the lifting arm 22 are of unitary construction.

With continued reference to fig. 1 to 4F, the lifting arm 22 is rotatably provided to the moving portion 21 such that the lifting arm 22 can be switched between a state in which the height of the open end 221 of the lifting arm 22 is higher than the height of the holding end 222 and a state in which the height of the open end 221 of the lifting arm 22 is lower than the height of the holding end 222. When the lifting arm 22 is in a state where the height of the open end 221 of the lifting arm 22 is higher than the height of the holding end 222, the syringe 100 can automatically slide into the holding groove 223 of the lifting arm 22 and the holding groove 223 held in the lifting arm 22 based on gravity, and when the lifting arm 22 is in a state where the height of the open end 221 of the lifting arm 22 is lower than the height of the holding end 222, the syringe 100 can automatically slide out of the holding groove 223 of the lifting arm 22 based on gravity.

For convenience of description and understanding, in the present invention, the state in which the height of the open end 221 of the lifting arm 22 is higher than the height of the holding end 222 may be defined as a slide-in state of the lifting arm 22, and correspondingly, the state in which the height of the open end 221 of the lifting arm 22 is lower than the height of the holding end 222 may be defined as a slide-out state of the lifting arm 22. Therefore, it can be understood that the lifting arm 22 can be switched between the slide-in state and the slide-out state by rotating the lifting arm 22 relative to the moving part 21, wherein the sample tube 100 can be automatically slid into the holding groove 223 of the lifting arm 22 based on gravity when the lifting arm 22 is in the slide-in state, and the sample tube 100 can be automatically slid out of the holding groove 223 of the lifting arm 22 based on gravity when the lifting arm 22 is in the slide-out state.

With continued reference to fig. 1-4F, the lifting unit 20 further includes at least one return element 23, opposite ends of the return element 23 being connected to the holding end 222 of the lifting arm 22 and the moving portion 21, respectively. The reset element 23 brings the initial state of the lifting arm 22 into the slide-in state, and after the lifting arm 22 has been switched into the slide-out state, the reset element 23 is arranged to automatically switch the lifting arm 22 from the slide-out state into the slide-in state.

Specifically, the reset element 23 is a tension spring, when the lifting arm 22 is not subjected to an external force for driving the state switching of the lifting arm 22, the reset element 23 contracts to keep the lifting arm 22 in the slide-in state, when the lifting arm 22 is subjected to an external force for driving the state switching of the lifting arm and is switched from the slide-in state to the slide-out state, the reset element 23 is stretched to accumulate elastic potential energy, and after the external force for driving the state switching of the lifting arm 22 is removed, the reset element 23 pulls the holding end 222 of the lifting arm 22 in a direction close to the moving part 21 in the process of restoring the initial state, so that the lifting arm 22 is automatically switched from the slide-out state to the slide-in state. Preferably, the number of resetting elements 23 is two, which are symmetrically arranged.

Alternatively, in other examples of the sample tube lifting device according to the present invention, the reset element 23 sets the initial state of the lifting arm 22 to the slide-out state, and the reset element 23 is configured to automatically switch the lifting arm 22 from the slide-in state to the slide-out state. Specifically, the reset element 23 is a compression spring, when the lifting arm 22 is not subjected to an external force that urges the state switching thereof, the reset element 23 is extended to keep the lifting arm 22 in the slide-out state, when the lifting arm 22 is subjected to an external force that urges the state switching thereof and is switched from the slide-out state to the slide-in state, the reset element 23 is compressed to accumulate elastic potential energy, and after the external force that urges the state switching of the lifting arm 22 is cancelled, the reset element 23 pushes the holding end 222 of the lifting arm 22 in a direction away from the moving portion 21 in the process of returning to the initial state, so that the lifting arm 22 is automatically switched from the slide-in state to the slide-out state.

Alternatively, in other examples of the device for lifting sample tubes according to the present invention, wherein the reset element 23 is a torsion spring, the middle portion of the reset element 23 is sleeved on a rotating shaft connecting the lifting arm 22 and the moving part 21, and two ends of the reset element respectively abut against the lifting arm 22 and the moving part 21.

With continued reference to fig. 1, 2A and 4, the lifting unit 20 further comprises an auxiliary arm 24, wherein the auxiliary arm 24 is disposed at the holding end 222 of the lifting arm 22, and the auxiliary arm 24 and the lifting arm 22 have an acute included angle therebetween, such that when the lifting arm 22 is switched from the slide-in state to the slide-out state, the auxiliary arm 24 can automatically push the sample tube 100 to slide the sample tube 100 out of the lifting arm 22.

In the particular embodiment of the sample tube lifting device shown in fig. 1 to 4F, the auxiliary arm 24 is mounted to the holding end 222 of the lifting arm 22. Alternatively, in other examples of the sample tube lifting device of the present invention, the auxiliary arm 24 may be welded to the holding end 222 of the lifting arm 22, or the auxiliary arm 24 may extend obliquely from the holding end 222 of the lifting arm 22 integrally.

Preferably, one end of the reset element 23 may be connected to the holding end 222 of the lifting arm 22 by being mounted to the auxiliary arm 24. That is, in the particular embodiment of the sample tube lifting device shown in fig. 1 to 4F, one end of the resetting element 23 is indirectly connected to the holding end 222 of the lifting arm 22. Alternatively, in other examples of the present invention, one end of the reset element 23 may be directly connected to the holding end 222 of the lifting arm 22.

With continued reference to fig. 1 to 4F, the sample tube lifting device further comprises a top end guide unit 30, the top end guide unit 30 having a top end guide rail 31, wherein the top end guide unit 30 is located at the predetermined height position. For example, the top end guide unit 30 may be adjacent to the body top end 11 of the lifting frame 10. When the moving part 21 of the lifting unit 20 drives the lifting arm 22 to move to the preset height position along the lifting frame 10, the open end 221 of the lifting arm 22 corresponds to the top end guide rail 31 of the top end guide unit 30, and after the lifting arm 22 is driven to switch from the slide-in state to the slide-out state, the sample tube 100 can slide into the top end guide rail 31 of the top end guide unit 30 from the holding groove 223 of the lifting arm 22 based on gravity, so as to complete the lifting of the sample tube 100.

Further, the top end guide unit 30 includes a guide portion 32, and the top end guide rail 31 is formed on the guide portion 32, wherein the guide portion 32 is located at the predetermined height position and is adjacent to the frame top end 11 of the lifting frame 10. When the moving part 21 moves the lifting arm 22 to the preset height position along the lifting frame 10 and the lifting arm 22 is in the slide-out state, the height of the open end 221 of the lifting arm 22 is the same as the height of the entrance of the guide part 32, or the height of the open end 221 of the lifting arm 22 is higher than the height of the entrance of the guide part 32, so as to allow the sample tube 100 to smoothly slide into the top end guide rail 31 of the top end guide unit 30 from the holding groove 223 of the lifting arm 22. After the syringe 100 slides into the top guide rail 31 of the top guide unit 30 from the holding groove 223 of the lift arm 22, opposite sides of the cap of the syringe 100 are caught on the upper surface of the guide portion 32.

Preferably, an end surface of the open end 221 of the lifting arm 22 is an inclined surface, so that when the moving part 21 drives the lifting arm 22 to move to the preset height position along the lifting frame 10 and the lifting arm 22 is in the slide-out state, an end surface of the guide part 32 and an end surface of the open end 221 of the lifting arm 22 can be adjacent to each other, so as to prevent the sample tube 100 from being caught between the guide part 32 and the lifting arm 22 when the sample tube 100 slides from the lifting arm 22 to the guide part 32, and thus the sample tube 100 can smoothly slide from the holding groove 223 of the lifting arm 22 into the top end guide rail 31 of the top end guide unit 30.

Preferably, the guide part 32 is obliquely disposed, and the oblique direction of the guide part 32 coincides with the oblique direction of the lifting arm 22 in the slide-out state, in such a way that the sample tubes 100 can be prevented from being stacked at the position of the entrance of the guide part 32 after the sample tubes 100 are automatically slid into the guide part 32 of the top end guide unit 30 from the lifting arm 22 based on gravity, so that the sample tube lifting apparatus can continuously lift a plurality of the sample tubes 100.

Further, the tip end guide unit 30 includes a stopper 33, the stopper 33 is disposed on an upper side of the guide portion 32, and an end surface of the stopper 33 protrudes from an end surface of the guide portion 32. In other words, the distance between the end surface of the blocking portion 33 and the lifting frame 10 is smaller than the distance between the end surface of the guide portion 32 and the lifting frame 10. With such a structure, when the moving part 21 moves the lifting arm 22 to the preset height position along the lifting frame 10, the open end 221 of the lifting arm 22 can be blocked by the blocking part 33 to drive the lifting arm 22 to rotate relative to the moving part 21, so that the lifting arm 22 is automatically switched from the slide-in state to the slide-out state, and at this time, the sample tube 100 held in the holding groove 223 of the lifting arm 22 is automatically slid into the guide part 32 of the top end guide unit 30 from the holding groove 223 of the lifting arm 22.

Preferably, the blocking portion 33 has an avoiding groove 331, the avoiding groove 331 of the blocking portion 33 corresponds to and communicates with the top end guide rail 31 of the top end guide unit 30, when the sample tube 100 slides from the holding groove 223 of the lifting arm 22 to the top end guide rail 31 of the top end guide unit 30, the avoiding groove 331 of the blocking portion 33 can avoid the tube cap of the sample tube 100, so as to avoid the tube cap collision of the sample tube 100 the blocking portion 33 and avoid the blocking portion 33 to block the sample tube 100 from sliding into the top end guide rail 31 of the top end guide unit 30.

With continued reference to fig. 1 to 4F, the sample tube lifting device comprises a bottom end guide unit 40, the bottom end guide unit 40 having a bottom end guide track 41, wherein the bottom end guide unit 40 is located at the position to be lifted. For example, the bottom end guide unit 40 may be adjacent to the frame body bottom end 12 of the lifting frame 10. When the moving part 21 of the lifting unit 20 moves the lifting arm 22 to the position to be lifted along the lifting frame 10, the open end 221 of the lifting arm 22 corresponds to the bottom end guide rail 41 of the bottom end guide unit 40, and the sample tube 100 is configured to be able to slide into the holding groove 223 of the lifting arm 22 in the slide-in state from the bottom end guide rail 41 of the bottom end guide unit 40, and to be held in the holding groove 223 of the lifting arm 22 in the slide-in state.

Preferably, the bottom end guide unit 40 is obliquely disposed, and the oblique direction of the bottom end guide unit 40 coincides with the oblique direction of the lift arm 22 in the slide-in state, in such a way that the sample tube 100 can be automatically slid from the bottom end guide rail 41 of the bottom end guide unit 40 into the holding groove 223 of the lift arm 22 based on gravity. Moreover, since the end surface of the open end 221 of the lifting arm 22 is an inclined surface, when the moving part 21 drives the lifting arm 22 to move to the position to be lifted along the lifting frame 10 and the lifting arm 22 is in the slide-in state, the end surface of the bottom end guide unit 40 and the end surface of the open end 221 of the lifting arm 22 can be adjacent to each other, so as to prevent the sample tube 100 from being jammed between the bottom end guide unit 40 and the lifting arm 22 when the sample tube 100 slides from the bottom end guide unit 40 to the holding groove 223 of the lifting arm 22, and therefore the sample tube 100 can smoothly slide from the bottom end guide rail 41 of the bottom end guide unit 40 into the holding groove 223 of the lifting arm 22.

With continued reference to fig. 1 to 4F, the moving portion 21 further includes a sliding block 211 and a suspension body 212 disposed on the sliding block 211, the sliding block 211 is slidably mounted on the lifting frame 10, wherein the suspension body 212 has a suspension space 2121, wherein the lifting arm 22 is rotatably mounted on the suspension body 212, and the holding groove 223 of the lifting arm 22 corresponds to and communicates with the suspension space 2121 of the suspension body 212. When the syringe 100 slides into the holding groove 223 of the lifting arm 22, the body of the syringe 100 can be suspended in the suspension space 2121 of the suspension body 212.

Specifically, the suspension body 212 has two suspension arms 2122, and the suspension space 2121 is formed between the two suspension arms 2122, wherein each extension arm 225 of the lifting arm 22 is rotatably mounted to each suspension arm 2122 of the suspension body 2121, respectively, so that the lifting arm 22 is rotatably mounted to the moving portion 21, and the holding groove 223 of the lifting arm 22 corresponds to and communicates with the suspension space 2121 of the suspension body 212.

With continued reference to fig. 1 to 4F, the sample tube lifting device includes a lifting driving unit 50, the lifting driving unit 50 further includes a lifting power source 51 and a lifting power transmission part 52 connected to the lifting power source 51, wherein the sliding block 211 of the moving part 21 is connected to the lifting power transmission part 52 in a driving manner, so that the lifting power source 51 can drive the moving part 21 to move the lifting arm 22 along the lifting frame 10 via the lifting power transmission part 52.

Specifically, the lifting power source 51 may be a driving motor or a combination of a driving motor and a gear box, wherein the lifting power source 51 may be disposed at the frame top end 11 of the lifting frame 10. The lifting power transmission part 52 may be a transmission belt, and the extending direction of the transmission belt is the same as the extending direction of the lifting frame 10, so that the lifting power transmission part 52 can transmit the power of the lifting power source 51 to the moving part 21 to drive the lifting arm 22 to move along the lifting frame 10 between the position to be lifted and the preset height position. Alternatively, in other examples of the sample tube lifting device of the present invention, the lifting power source 51 may be disposed at the frame body bottom end 12 of the lifting frame 10.

Referring to fig. 4A and 4B, the lifting unit 20 is in the position to be lifted, the open end 221 of the lifting arm 22 of the lifting unit 20 is adjacent to the outlet of the bottom end guide unit 40, and the holding groove 223 of the lifting arm 22 corresponds to the bottom end guide rail 41 of the bottom end guide unit 40. The sample tube 100 can automatically slide into the holding groove 223 of the lifting arm 22 from the bottom end guide rail 41 of the bottom end guide unit 40 based on gravity, and at this time, the opposite sides of the cap of the sample tube 100 are caught on the upper surfaces of the two extending arm bodies 225 of the lifting arm 22, and the body of the sample tube 100 is suspended in the suspension space 2121 of the suspension body 212 of the moving part 21.

Referring to fig. 4C, the lifting power source 51 drives the moving part 21 through the lifting power transmission part 52 to drive the lifting arm 22 to move along the lifting frame 10 from the position to be lifted to the preset height position. In this process, the reset component 23 keeps the lifting arm 22 in the slide-in state, that is, the reset component 23 keeps the height of the opening end 221 of the lifting arm 22 higher than the height of the holding end 222, so that the sample tube 100 can be prevented from falling from the holding groove 223 of the lifting arm 22 during the process of lifting the sample tube 100, thereby ensuring the reliability and safety of lifting the sample tube 100, and stably lifting the sample tube 100.

Referring to fig. 4D to 4F, when the moving part 21 moves the lifting arm 22 to the preset height position, the blocking part 33 of the top end guide unit 30 blocks the open end 221 of the lifting arm 22, so that the lifting arm 22 is switched from the slide-in state to the slide-out state, and at this time, on one hand, the restoring element 23 is stretched to accumulate elastic potential energy, and on the other hand, the tilt direction of the lifting arm 22 is consistent with that of the guide part 32 of the top end guide unit 30, so as to allow the sample tube 100 held in the holding groove 223 of the lifting arm 22 to automatically slide out of the holding groove 223 of the lifting arm 22 and towards the top end guide rail 31 of the top end guide unit 30 based on gravity, so as to complete the lifting of the sample tube 100. Preferably, during the switching of the lifting arm 22 from the slide-in state to the slide-out state, the auxiliary arm 24 can push the sample tube 100 out of the holding groove 223 of the lifting arm 22, so that the sample tube 100 smoothly enters the top end guide rail 31 of the top end guide unit 30.

It can be understood that when the moving portion 21 moves the lifting arm 22 from the preset height position to the to-be-lifted position, the reset element 23 switches the lifting arm 22 from the slide-out state to the slide-in state when the reset element 23 returns to the initial state due to the open end 221 of the lifting arm 22 being away from the blocking portion 33.

Fig. 5 to 7 show the sample tube lifting device according to another preferred embodiment of the present invention, different from the sample tube lifting device shown in fig. 1 to 4F, in the preferred example of the sample tube lifting device of the present invention shown in fig. 5 to 7, the guiding portion 32 of the top end guiding unit 30 is horizontally disposed, when the moving portion 21 drives the lifting arm 22 to move to the preset height position along the lifting frame 10, the open end 221 of the lifting arm 22 can be blocked by the blocking portion 33 to drive the lifting arm 22 to rotate relative to the moving portion 21, so that the lifting arm 22 is switched from the slide-in state to the slide-out state to allow the sample tube 100 held in the holding groove 223 of the lifting arm 22 to automatically slide out of the holding groove 223 of the lifting arm 22 and slide into the top end guiding rail 30 And (3) a track 31.

In order to avoid that the sample tubes 100 slid into the top end guide track 31 of the top end guide unit 30 are stacked at the entrance of the guide part 32 and affect the lifting of the subsequent sample tubes 100, the sample tubes 100 slid into the top end guide track 31 of the top end guide unit 30 can be pushed away from the entrance of the guide part 32. Therefore, the sample tube lifting device of the present invention further comprises a pushing unit 60, wherein the pushing unit 60 is adjacently disposed to the top end guide unit 30, and the pushing unit 60 is used for pushing the sample tube 100 sliding into the top end guide track 31 of the top end guide unit 30 to move away from the entrance of the guide portion 32.

Specifically, the pushing unit 60 includes a seat body 61, a pushing driving portion 62 and a pushing portion 63, wherein the pushing driving portion 62 is disposed on the seat body 61, wherein the pushing portion 63 includes a mounting body 631 and a pushing arm 632 integrally extending downward from the mounting body 631, and the mounting body 631 of the pushing portion 63 is drivably mounted on the pushing driving portion 62. The holder body 61 of the push unit 60 is adjacently disposed to the top end guide unit 30, and the push arm 632 can extend to the top end guide rail 31 of the top end guide unit 30 and move along the top end guide rail 31, so that the sample tube 100 slid into the top end guide rail 31 of the top end guide unit 30 is pushed by the push arm 632 of the push part 63 to move away from the entrance of the guide part 32.

Specifically, the push driving part 62 includes a push power source 621 and a push power transmission part 622 drivably connected to the push power source 621, wherein the mounting body 631 of the pushing part 63 is mounted to the push power transmission part 622. The pushing power source 621 is thus able to drive the pushing part 63 to move through the pushing power transmission part 622. More specifically, the pushing power transmission part 622 includes a screw rod 6221 and a nut 6222 sleeved to the screw rod 6221, the screw rod 6221 is drivably connected to the pushing power source 621, and opposite ends of the screw rod 6221 are rotatably mounted to the seat bodies 61, respectively, wherein the mounting body 631 of the pushing part 63 is mounted to the nut 6222. When the pushing power source 621 drives the lead screw 6221 to rotate, the lead screw 6221 and the nut 6222 can cooperate with each other to move the nut 6222 along the lead screw 6221, so that the nut 6222 drives the pushing part 63 to move so that the pushing arm 632 moves along the top end guide track 31 to push the sample tube 100 sliding into the top end guide track 31 of the top end guide unit 30 to move away from the inlet of the guiding part 32.

It should be noted that the driving power source 621 can be a driving motor or a combination of a driving motor and a transmission box, which is installed at the end of the seat body 61.

Preferably, the holder body 61 has a slide rail 611, and the nut 6222 is slidably mounted on the slide rail 611 of the holder body 61 and can be driven to move along the slide rail 611 of the holder body 61.

Further, referring to fig. 5 to 7, the moving portion 21 of the lifting unit 20 has an avoiding space 213, and the push arm 632 of the pushing portion 63 of the pushing unit 60 can be inserted into the avoiding space 213 of the moving portion 21 during the process that the moving portion 21 is driven to move the lifting frame 10 from the position to be lifted to the preset height position, so as to avoid the collision between the push arm 632 and the moving portion 21.

The process of lifting the sample tube 100 by the sample tube lifting device shown in fig. 5 to 7 is as follows.

First, the lifting unit 20 is in the position to be lifted, the open end 221 of the lifting arm 22 of the lifting unit 20 is adjacent to the outlet of the bottom end guide unit 40, and the holding groove 223 of the lifting arm 22 corresponds to the bottom end guide rail 41 of the bottom end guide unit 40. The syringe 100 can automatically slide into the holding groove 223 of the lifting arm 22 from the bottom end guide rail 41 of the bottom end guide unit 40 based on gravity, and at this time, opposite sides of the cap of the syringe 100 are caught on the upper surfaces of the two extension arm bodies 225 of the lifting arm 22, and the body of the syringe 100 is suspended in the suspension space 2121 of the suspension body 212 of the moving part 21.

Next, the lifting power source 51 drives the moving part 21 through the lifting power transmission part 52 to drive the lifting arm 22 to move along the lifting frame 10 from the position to be lifted to the preset height position. In this process, the reset component 23 keeps the lifting arm 22 in the slide-in state, that is, the reset component 23 keeps the height of the opening end 221 of the lifting arm 22 higher than the height of the holding end 222, so that the sample tube 100 can be prevented from falling from the holding groove 223 of the lifting arm 22 during the process of lifting the sample tube 100, thereby ensuring the reliability and safety of lifting the sample tube 100, and stably lifting the sample tube 100.

Then, in the process that the moving portion 21 drives the lifting arm 22 to move to the preset height position, the pushing arm 632 of the pushing portion 63 can be inserted into the avoiding space 213 of the moving portion 21, so as to avoid collision between the pushing arm 632 and the moving portion 21. When the moving part 21 moves the lifting arm 22 to the preset height position, the blocking part 33 of the top end guide unit 30 blocks the open end 221 of the lifting arm 22, so that the lifting arm 22 is switched from the slide-in state to the slide-out state, at this time, on one hand, the reset element 23 is stretched to accumulate elastic potential energy, and on the other hand, the lifting arm 22 is inclined in such a way that the height of the open end 221 of the lifting arm 22 is lower than the height of the holding end 222, so as to allow the sample tube 100 held in the holding groove 223 of the lifting arm 22 to automatically slide out of the holding groove 223 of the lifting arm 22 and slide toward the top end guide rail 31 of the top end guide unit 30 based on gravity. In the process of switching the lift arm 22 from the slide-in state to the slide-out state, the auxiliary arm 24 can push the sample tube 100 out of the holding groove 223 of the lift arm 22, so that the sample tube 100 can smoothly enter the leading end guide rail 31 of the leading end guide unit 30.

Fourthly, when the moving part 21 drives the lifting arm 22 to move from the preset height position to the position to be lifted, since the open end 221 of the lifting arm 22 is far away from the blocking part 33, when the reset element 23 returns to the initial state, the reset element 23 switches the lifting arm 22 from the slide-out state to the slide-in state. After the push arm 632 of the push portion 63 is disengaged from the avoidance space 213 of the moving portion 21, the push power source 621 can drive the push arm 632 of the push portion 63 to enter the tip end guide rail 31 of the tip end guide unit 30 from the entrance of the guide portion 32 through the push power transmission portion 622, and when the push arm 632 is driven to move along the tip end guide rail 31 of the tip end guide unit 30, the push arm 632 can push the sample tube 100 slid into the tip end guide rail 31 of the tip end guide unit 30 to move away from the entrance of the guide portion 32.
