Thus, after the simple initial adjustment is completed, for most of the ordinary users, the eye drop dropping operation for both eyes can be performed quickly by only directly rotating the rotating lever 24 to the left and right rotating limit positions.
It is worth supplementing and explaining that the translation limit position and the rotation limit position are both provided with a left limit and a right limit, and the left limit is used when the left eye is dripped, and the right limit is used when the right eye is dripped; different users solve the problem of different requirements on the translation and rotation limit positions caused by different situations of different users through the mode of individually setting the limit positions when the movable base 21 is used for the first time, the adaptability is strong, obviously, the limit positions are set for the first time, and then secondary setting is not needed, so that the movable base 21 and the rotating rod 24 only need to be translated and rotated with care until resistance is felt by the users when the movable base is used for the subsequent time, and then the movable base stops.
FIG. 16 is a schematic view of analysis of the drop coverage after integrated adjustment based on that shown in FIG. 15. In order to meet the needs of a few special users, such as special cases of eye distance specificity caused by asymmetry/injury/scald of the face, especially face-lifting, deformity and deformity of eyes, or asymmetry of eyes, the present invention can also make the drop point cover a large area as shown in fig. 16 (the dotted line in the figure indicates the movable area of the drop point) by comprehensively adjusting the horizontal position of the movable base 21 relative to the frame 12 and the circumferential position of the rotating rod 24 relative to the lockable connecting rotating shaft 22 on the basis of the initial adjustment as shown in fig. 15.
Fig. 17 is a schematic view of a three-dimensional structure after being folded according to an embodiment of the present invention, and fig. 18 is a diagram illustrating an effect of the three-dimensional structure after being folded and placed in a storage case such as a glasses case according to an embodiment of the present invention.

The second embodiment is described in detail.
Fig. 19 is a pneumatic schematic diagram of a pneumatic system according to a second embodiment of the present invention. As shown in fig. 19, the pneumatic system further includes a reversing valve, a cylinder; the cylinder main body is fixedly connected with the mirror frame 12; a piston rod of the cylinder is fixedly connected with the movable base 21; the air bag 43 is respectively connected with the air cylinder and the air cushion 41 in an airtight way through a reversing valve; the reversing valve is used for controlling the action of the piston rod of the air cylinder and switching the inflating object of the air bag 43, so that the horizontal position of the movable base 21 relative to the mirror frame 12 and the degree of holding and extruding the bottle body of the eye drop bottle are respectively adjusted;
preferably, the cylinder is a double piston rod cylinder 7 as shown in fig. 19; two piston rods of the double-piston rod type cylinder 7 are arranged in bilateral symmetry around the vertical middle surface of the mirror frame 12; the double-piston rod type cylinder 7 is embedded in the spectacle frame 12;
more specifically, in this example, as shown in fig. 19, the selector valves include a two-position four-way selector valve 5 and a three-position four-way selector valve 6; an A/B air outlet of the two-position four-way reversing valve 5 is communicated with a P air inlet of the three-position four-way reversing valve 6, and an A air outlet (B air outlet) of the three-position four-way reversing valve 6 is communicated with a left piston cavity (right piston cavity) of the double-piston rod type cylinder 7.
Preferably, in order to facilitate the air discharge of the air spring 41 and to maintain the piston chamber at a constant pressure in any operating state of the directional control valve, the air bag 43 includes a quick air discharge valve, the air bag 43 is communicated with the two-position four-way directional control valve 5 through the quick air discharge valve 431, and the two-position four-way directional control valve 5 is communicated with the air spring 41 through the quick air discharge valve 431.
The control logic for the diverter valve is shown in table 1 below.
TABLE 1 control logic table of change-over valve
Suppose that the left eye is dripped first each time, and the states of the two reversing valves are 'right' and 'left' (the right position of the two-position four-way reversing valve 5 and the left position of the three-position four-way reversing valve 6, the same reason is briefly described below).
Starting from the states of the reversing valve after dripping is finished, namely right and left:
① to turn to left or right state, that is, the air bag 43 is held and pressed to inflate, the movable base 21 is moved to left to limit position, and the rotating rod 24 is pulled to left limit position by hand;
② is adjusted to right or middle state, the air bag 43 is held and pressed to inflate the air cushion 41 to squeeze the eye drop bottle to complete the eye drop action;
③ is adjusted to left or right state, that is, the air bag 43 is pressed to inflate, the movable base 21 is moved to right to limit position, and the rotating rod 24 is pulled to right limit position by hand;
④ is adjusted to a 'right' or 'middle' state, wherein the air bag 43 is held to inflate, the air cushion 41 expands to press the eyedrop bottle to complete the right eye dropping action, the air cushion 41 releases air under the elastic restoring force of the eyedrop bottle (or with the slight pressing force of the hand), and the eyedrop bottle body recovers a bulging state;
⑤ to the right and left states, the device is removed, the movable base 21 is translated at a suitable height to a position convenient for folding, and then the rotary rods 24 and the temples 11 are folded to be placed in the storage case.
In conclusion, the invention has the following beneficial effects:
1) the adaptability is high. On the basis of initial adjustment, the dropping liquid dropping point can cover a larger area by comprehensively adjusting the horizontal position of the movable base 21 relative to the mirror frame 12 and the circumferential position of the connecting rotating shaft 22 which can be locked by the rotating rod 24 relative to the mirror frame, so that the dropping liquid dropping point meets the requirements of most common users and a few special users, and has good crowd adaptability; meanwhile, under the action of external force, the bottle bottom pressing block 31 can be pulled out by a distance relative to the bottle body clamping seat 34 along the connecting pull rod 33, so that the invention can be adapted to common eye drop bottles in the market.
2) The operation is convenient and comfortable. After the initialization adjustment of the invention is simply completed, for most of ordinary users, the operation of dropping eyedrops in both eyes can be quickly carried out only by directly rotating the rotating rod 24 to the left and right rotating limit positions; in addition, the old can press the air bag 43 at the waist side to complete the liquid dropping, and the operation is convenient and comfortable.
3) The dropping liquid quantity is controllable. The air cushion is gradually inflated and expanded by gradually squeezing the air bag 43, and the dropping amount can be easily and quantitatively controlled by squeezing the bottle wall of the eyedrop bottle with the help of uniform and gradually increased uniform pressure generated by the air cushion instead of the double fingers of the user.
4) Is safe and reliable. The relative height of the eyedrop bottle mounted in the bottle body holder 34 and the frame assembly 1 is not changed by the position change of the movable base 21 and the rotary rod 24, thereby solving the problem that the eyedrop may be mistakenly poked in the conventional dropping process.
5) Is healthy and sanitary. The mouth part of the eye drop bottle can penetrate through the hole of the eye drop bottle mouth, so that the liquid medicine and the bottle mouth of the eye drop bottle can not be directly contacted with the eye drop bottle in the whole process, and the eye drop bottle has the advantage of sanitation and cleanness; in addition, once the liquid medicine is adjusted and determined, the dropping position of the liquid medicine is determined, and the liquid medicine can not drop to the outer skin of eyes, so that a user can be prevented from directly wiping the liquid medicine by hands unconsciously, and the liquid medicine is safe and sanitary.
6) Easy to store and carry. The invention can be placed in a common storage box after being folded, and has good portability.
7) The air pressure generating device in the pneumatic system can directly select the inflatable ball of the sphygmomanometer, and other elements can be simply made of materials such as plastics, rubber and the like, so the pneumatic system has simple structure and low cost.
