[0034] The output end of the motor 21 is connected to the high-pressure pump 20. When the motor 21 is started, it drives the high-pressure pump 20 to operate, so that the suction force is transmitted through the transport pipe 24 to the absorption pipes 25 at both ends of the pressure-increasing pipe 26 by the pressure-increasing pipe 26. One absorption pipe 25 sucks the liquid in the test tube 8 into the interior of the transport pipe 24. When the liquid reaches the pressure-increasing pipe 26 along the suction force and contacts the liquid sensor 27 in the pressure-increasing pipe 26, the motor 21 can be stopped. According to the different heights at both ends of the transport pipe 24, the liquid in the pipe can flow into the interior of another test tube 8 along the transport pipe 24. The transport pipe 24 passes through the clamping block 22 through the stabilizing holes 23, which can reduce the shaking of the device when using the device.

[0035] A plurality of first sliding grooves 2 are formed in the upper end surface of the fixed base 1. A first sliding block 3 is slidably disposed in each of the plurality of first sliding grooves 2. Two moving platforms 4 are fixedly disposed on the upper end surfaces of the plurality of first sliding blocks 3.

[0039] Working principle: When using this device, first slide the moving platform 4 on the fixed base 1 through the first slide block 3 in the first slide groove 2, so that the moving platform 4 can be moved to different positions when needed. Then, there is a rail block 11 in the slide rail groove 10 on the extension block 9 on the fixed base 1, and multiple slide rail blocks 12 are installed on the rail block 11, which is convenient for moving the support block 13 on the slide rail block 12 to a suitable position. Then, slide through the second slide block 16 in the second slide groove 14 on the support block 13, which is convenient for finding the insertion port when using the device. Then, the output end of the motor 21 is connected to the high-pressure pump 20. When the motor 21 is started, it drives the high-pressure pump 20 to operate, so that the booster pipe 26 transmits the suction force through the transport pipe 24 to the absorption pipes 25 at both ends of the booster pipe 26, and one absorption pipe 25 sucks the liquid in the test tube 8 into the interior of the transport pipe 24.
