The clamping assembly 400 is arranged on the first clamping block 100, and the clamping assembly 400 is used for clamping the micro flow pipe 300 by the first clamping block 100 and the second clamping block 200 or loosening the micro flow pipe 300 by the first clamping block 100 and the second clamping block 200. The container is used for containing the external phase liquid, and the micro flow pipe 300, the first clamping block 100, the second clamping block 200 and the clamping assembly 400 can be immersed in the external phase liquid in the container.

[0033] It needs to be explained that in the prior art, when the micro flow pipe 300 needs to be disassembled from the microsphere preparation experimental device, the experimental personnel first need to use tools such as wrenches, screwdrivers and pliers to disassemble the corresponding shell or cover plate, so that the micro flow pipe 300 is exposed. Then the experimental personnel need to use tools to gradually disassemble the pipelines, screws or other fixing parts connected with the micro flow pipe 300, and then complete the disassembly of the micro flow pipe 300. Similarly, the installation steps of the micro flow pipe 300 are opposite to the disassembly steps, which will not be described further here. As can be seen, the disassembly and installation steps of the micro flow pipe 300 are relatively cumbersome, which is not conducive to improving the convenience of disassembly and installation of the micro flow pipe 300.

In the embodiment of the utility model, the first clamping block 100, the second clamping block 200 and the clamping assembly 400 are all made of stainless steel.

[0035] It can be understood that when the microfluidic tube 300 needs to be installed, the experimenter can place the microfluidic tube 300 between the first clamp block 100 and the second clamp block 200. Then the experimenter can control the clamping assembly 400 to make the second clamp block 200 and the first clamp block 100 abut the upper and lower ends of the microfluidic tube 300 respectively, and make the first clamp block 100 and the second clamp block 200 clamp the microfluidic tube 300, that is, the rapid installation of the microfluidic tube 300 is completed. When the microsphere preparation needs to be carried out, the experimenter installs the output end of the infusion device into the second mounting hole 210 on the second clamp block 200, so that the output end of the infusion device communicates with the microfluidic tube 300. After the installation of the output end of the infusion device is completed, the experimenter places the first clamp block 100, the second clamp block 200, the microfluidic tube 300 and the clamping assembly 400 in the container, so that the first clamp block 100, the second clamp block 200, the microfluidic tube 300 and the clamping assembly 400 are immersed in the external phase liquid in the container. Then the experimenter starts the infusion device, and the infusion device can send the internal phase liquid into the microfluidic tube 300. Then the internal phase liquid passes through the plurality of microfluidic holes on the tube wall of the microfluidic tube 300 and diffuses into the external phase liquid in the container to prepare the microsphere particles. When the microfluidic tube 300 needs to be disassembled, the experimenter can control the clamping assembly 400 to loosen the microfluidic tube 300 from the first clamp block 100 and the second clamp block 200, and the experimenter can take out the microfluidic tube 300 from between the first clamp block 100 and the second clamp block 200, that is, the rapid disassembly of the microfluidic tube 300 is completed. The microfluidic tube 300 in the microsphere preparation experimental device is clamped and loosened by the first clamp block 100 and the second clamp block 200, that is, the rapid installation and disassembly of the microfluidic tube 300 is completed, which simplifies the disassembly and installation steps of the microfluidic tube 300, and further facilitates the convenience of disassembly and installation of the microfluidic tube 300.

[0036] Reference Figures 1 to 4The clamping assembly 400 comprises two studs 430 and two first fasteners 410, the second clamping block 200 is provided with two guide holes 240, the lower ends of the two studs 430 are connected with the first clamping block 100, the micro flow pipe 300 is arranged between the two studs 430, the upper ends of the two studs 430 are respectively arranged in the two guide holes 240, and the two first fasteners 410 are respectively screwed with the two studs 430. The two first fasteners 410 can be uniformly pressed on the side of the second clamping block 200 away from the first clamping block 100, so that the first clamping block 100 and the second clamping block 200 clamp the micro flow pipe 300. It can be understood that the two studs 430 are parallel to the up-down direction, and the second clamping block 200 is arranged above the first clamping block 100. The second clamping block 200 is provided with two guide holes 240, and the two studs 430 on the first clamping block 100 are respectively arranged in the two guide holes 240 on the second clamping block 200, so that the second clamping block 200 can be close to or away from the first clamping block 100 along the up-down direction. When the micro flow pipe 300 needs to be installed, the experimenter can first make the second clamping block 200 away from the first clamping block 100, so that the distance between the first clamping block 100 and the second clamping block 200 is increased, and then the experimenter puts the micro flow pipe 300 between the first clamping block 100 and the second clamping block 200. Under the gravity of the second clamping block 200, the second clamping block 200 abuts against the upper end of the micro flow pipe 300, and the first clamping block 100 abuts against the lower end of the micro flow pipe 300. Then the experimenter screws the two first fasteners 410 with the two studs 430 respectively and tightens the two first fasteners 410, so that the two first fasteners 410 are uniformly pressed on the side of the second clamping block 200 away from the first clamping block 100. Under the action of the two first fasteners 410, the second clamping block 200 has a tendency to move towards the first clamping block 100, so that the second clamping block 200 and the first clamping block 100 clamp the micro flow pipe 300, and the installation of the micro flow pipe 300 can be quickly completed.

[0037] When the micro flow pipe 300 needs to be disassembled, the experimenter can unscrew the two first fasteners 410 and make the second clamping block 200 rise away from the first clamping block 100, so that the first clamping block 100 and the second clamping block 200 release the micro flow pipe 300, and then the experimenter can take out the micro flow pipe 300 from between the first clamping block 100 and the second clamping block 200, so that the disassembly of the micro flow pipe 300 can be quickly completed. In the embodiment of the utility model, the first fastener 410 can be a first nut. As an embodiment of the utility model, the first nut is provided with a first holding part, and the experimenter can drive the first nut to rotate through the first holding part.

It can be understood that after the two first fasteners 410 are pressed on the side of the second clamping block 200 away from the first clamping block 100 by the experimenter, the experimenter can tighten the two second fasteners 420, so that the two second fasteners 420 are uniformly pressed on the side of the second clamping block 200 close to the first clamping block 100. At this time, the two first fasteners 410 and the two second fasteners 420 are in a state of clamping the second clamping block 200, so that the position of the second clamping block 200 relative to the first clamping block 100 in the up-down direction is fixed, ensuring that the second clamping block 200 does not shake during the preparation of the microspheres, so that the preparation of the microspheres can proceed smoothly. In the embodiment of the utility model, the second fastener 420 can be a second nut. As an embodiment of the utility model, a second gripping portion is arranged on the second nut, and the experimenter can drive the second nut to rotate through the second gripping portion.

As an embodiment of the utility model, the microsphere preparation experiment device further comprises a first sealing gasket, and the inner bottom wall of the first positioning groove 120 abuts against the lower end of the microflow pipe 300 through the first sealing gasket. It can be understood that the lower end of the microflow pipe 300 extends into the first positioning groove 120, and the inner bottom wall of the first positioning groove 120 abuts against the lower end of the microflow pipe 300.

It can be understood that when the microsphere needs to be prepared, the experimenter can screw the plugging head 130 in the first mounting hole 110, so as to prevent the internal phase liquid in the micro flow pipe 300 from overflowing from the first mounting hole 110. When the micro flow pipe 300 needs to be cleaned, the experimenter can screw the plugging head 130 out of the first mounting hole 110, and then introduce clean water into the micro flow pipe 300, so that the clean water can be discharged from the first mounting hole 110, so that the experimenter can clean the micro flow pipe 300.
