The principle of the scheme is as follows: in practical application, the piston is a heavy piston made of iron or steel and the like, the ball is a light ball made of plastic and the like, and two liquid medicine bottles needing drip irrigation are respectively placed in the first hanging cylinder and the second hanging cylinder. When the infusion tube is started, the first hanging tube is positioned at the end part of the lever, the second hanging tube is close to the middle part of the lever, one end of the lever, which is provided with the first hanging tube, is inclined downwards, and the infusion tube penetrates through the chuck and is inserted into the liquid medicine bottle in the first hanging tube. When the liquid medicine in the liquid medicine bottle is gradually reduced in the process of carrying out drip irrigation through the liquid conveying pipe, the mass of the liquid medicine bottle becomes light, one end, provided with the first rack, of the lever is lifted up due to the fact that the weight of the end becomes light, the vertical rack on the first hanging barrel rises along with the first hanging barrel, the first bevel gear meshed with the vertical rack is pushed to rotate, and due to the fact that the first transverse rack is meshed with the first bevel gear, the first transverse rack moves transversely under the rotation of the first bevel gear. The first transverse rack is gradually close to the middle part of the lever, and contacts and pushes the second transverse rack to enable the second transverse rack to move transversely. The second rack bar moves and pushes the second bevel gear engaged therewith to rotate, thereby rotating the spool on the second bevel gear and lengthening the rope wound on the spool. Meanwhile, the second transverse rack drives the second hanging cylinder to move towards the end of the lever, and the spring is compressed. At this time, because the liquid medicine in the liquid medicine bottle in the first hanging barrel is completely infused and the weight of the liquid medicine bottle in the first hanging barrel is less than that of the liquid medicine bottle in the second hanging barrel, one end of the lever, which is provided with the second hanging barrel, sinks to be lower than the other end of the lever.
The second transverse rack moves to slide out of the pipeline, the pipeline is opened, the pull rope is lengthened, the piston slides downwards gradually along the pipeline under the action of gravity until the pull rope is stretched straight, so that air in the pipeline is extruded, and the air flow pushes the ball in the elbow to slide downwards. Because the bent pipe is spiral, the ball drives the supporting rod and the clamping head to rotate and sink along the bent pipe. When the chuck sinks, the infusion tube is pulled downwards, the infusion tube is pulled out from the liquid medicine bottle on the first hanging tube, then the infusion tube moves to the lower part of the second hanging tube along with the chuck, meanwhile, the second hanging tube carries the liquid medicine bottle to sink, the liquid medicine bottle automatically contacts with the needle head of the infusion tube, and under the action of the inertial impact force of the liquid medicine bottle, the needle head is automatically inserted into the liquid medicine bottle, so that the automatic bottle replacement of the infusion support is realized.

When the weight of the liquid medicine bottle in the second hanging cylinder is gradually reduced, one end of the lever, which is provided with the second hanging cylinder, is gradually lifted. Because the liquid medicine bottle quality becomes light to in the in-process that the second horizontal rack rises, the pressure of second horizontal rack that the spring received reduces gradually, when second horizontal rack rises to certain degree, the elasticity of spring will promote the second horizontal rack and move the return to the middle part of lever. The second transverse rack moves reversely to enable the second bevel gear to rotate reversely, the winding shaft rotates reversely along with the second bevel gear to shorten the pull rope, and therefore the piston is lifted upwards, the piston moves upwards to enable the round ball in the bent pipe to be pushed by air flow to move upwards to return. The ball moves to tear the infusion tube out of the liquid medicine bottle, so that the liquid medicine bottle automatically stops infusion, and the liquid medicine bottle and the clamping head rotate together to lift and return. The ball collides the lateral wall of return bend once more of in-process, sends the collision sound to the suggestion is driped irrigation and is accomplished, in order to remind the experimenter in time to carry out follow-up experiment or observation. The first alarm prompt is mainly to extrude gas into the bent pipe through the pipeline, so that the air pressure in the bent pipe is increased, and the gas in the bent pipe vibrates and collides the bent pipe through the vibration of the round ball to realize sound production, so that the sound is more stuffy in an environment with higher air pressure; and in the warning suggestion of second time, the piston moved up, the air current is by the updraft, and the air current pressure in the return bend is less, is difficult to the vibration sound production, consequently only realizes the sound production through the ball to the collision of return bend, and sound is comparatively loud, and the stereo set that twice sent is different to some extent, and easily the difference makes the experimenter correctly distinguish, avoids the experimenter to produce and obscures.
The beneficial effect of this scheme: according to the invention, the piston is moved downwards through the change of the weight of the liquid medicine bottle, the liquid conveying pipe is automatically inserted into another liquid medicine bottle, the automatic replacement of the liquid medicine bottle can be realized, the ball is pushed to collide in the bent pipe through air flow, two alarm prompts are respectively realized, when the first alarm prompt is given, the air flow in the bent pipe vibrates to collide with the bent pipe through the vibration of the ball so as to prompt the automatic bottle replacement, when the second alarm prompt is given, the collision sounding of the bent pipe is only given an end prompt through the ball, and an experimenter can clearly distinguish.
