In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below by way of examples with reference to the accompanying drawings in the present invention.

The working principle is as follows:

before the head-wearing type eye holographic optometer is used, firstly, a neck ring 19 assembled at the lower end of an optometer main body 1 is worn on the neck of a user, and in an initial state, a positioning block 204 arranged on the outer surface of the bottom end of a supporting rod 203 at the lower end of the optometer main body 1 is clamped in a group of positioning holes 202 at the lowest end of three groups of positioning holes 202 formed in an upper surface connecting cylinder 201 of the neck ring 19, so that the distance between the optometer main body 1 and the neck ring 19 is the minimum at the moment.

Further, when the interval is great between wearer's eye and the neck, locating piece 204 can be pressed this moment, make locating piece 204 move to the inside of connecting cylinder 201 from the locating hole 202 outside of lower extreme, then move up bracing piece 203, make the inside of locating piece 204 joint at several other groups of locating holes 202 of bracing piece 203 bottom installation, and then make the interval between optometry main part 1 and the neck ring 19 grow gradually, make the total support length to bracing piece 203 adjust, with the demand that satisfies different support length between different crowds' its eye and neck when wearing.

Further, after the length adjustment of neck ring 19 and bracing piece 203 is accomplished, make eyesight appearance main part 1 be located the one side that is close to user's eye this moment, press close to eyesight appearance main part 1 with user's eye and install one side of display mirror 5 after that, and under the effect of rubber circle 6, make user's eye surface can laminate mutually with the surface of rubber circle 6, and then press close to the relatively poor condition of eye sense of touch that causes with preventing that user's eye surface is direct with eyesight appearance main part 1, and then cause user's eye discomfort easily.

Further, when the two groups of straps are in an initial state, the length of the first strap 3 is fixed, the total length of the second strap 4 is greater than that of the first strap 3, one end of the second strap 4 is wound on the outer surface of the movable rod 10, and the other parts of the second strap 4 are not wound on the outer surface of the movable rod 10, so that the length of the second strap 4 located outside is the longest, and when the two groups of straps are connected with the first strap 3, the circumference formed by the two groups of straps is the longest.

Further, when wearing optometry appearance main part 1 at the user head through two sets of bandages, at this moment laminate optometry appearance main part 1 and user's eye earlier, then start to the direction removal of cassette 8 and cardboard 9 of two sets of bandage one end installations from connecting seat 2 to make the cardboard 9 joint of 4 one ends of second bandage in the inside of the cassette 8 of 3 one end installations of first bandage, make and be connected between two sets of bandages.

Further, can directly rotate the connecting rod 12 of the 2 upper surfaces of connecting seat that 4 departments of second bandage are connected for connecting rod 12 drives the movable rod 10 that its bottom is connected and carries out clockwise rotation, thereby makes second bandage 4 twine gradually at the surface of movable rod 10, makes the overall length of second bandage 4 shorten gradually, and then makes the side of second bandage 4 and first bandage 3 laminate with user's head surface mutually, can stop rotating connecting rod 12 this moment.

And simultaneously, in the process of clockwise rotation connecting rod 12, the thorn on the outer surface of ratchet 13 of connecting rod 12 surface mounting can push pawl 142 of its inside activity joint to move to one side for pawl 142 compresses torsional spring 144, then under the resilience effect of torsional spring 144, makes pawl 142 can joint in the inside of ratchet 13 again, carries out spacing fixed to the connecting rod 12 of the inside grafting of ratchet 13, so that the movable rod 10 that has second bandage 4 of winding is in fixed state.

In addition, when the next user uses the medical bandage, when the total length between the two groups of the medical bandages is short, the pulling plate 141 can be pulled upwards first, so that the pulling plate 141 drives the pawl 142 mounted in the pulling plate 141 to slide upwards, the pawl 142 is moved out of the ratchet wheel 13, the ratchet wheel 13 is in a complete moving state, the connecting rod 12 can be rotated anticlockwise, one end of the second bandage 4 wound on the outer surface of the moving rod 10 is gradually far away from the outer surface of the moving rod 10, and the total length of the second bandage 4 is lengthened, so that the length between the two groups of the bandages meets the requirements of different head circumferences of users.

Finally, when the second strap 4 is engaged with the side of the first strap 3 to the outer surface of the head of the user, the optometry main body 1 can be stably worn on the outer surface of the eyes of the user, and then the eyes of the user can be detected by the controller controlling the optometry main body 1.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
