[0033] The main body 2 further comprises a dynamic pressure groove 27 movably connected to the left part of the upper side edge of the bottom plate 21 to have the left-right translation function, and correspondingly, a third notch 213 is arranged on the left part of the upper side edge of the bottom plate 21, and the dynamic pressure groove 27 is movably arranged in the third notch 213, and the transverse width of the third notch 213 is greater than the transverse length of the dynamic pressure groove 27.

[0034] The front outer wall of the bottom plate 21 is further fixed with a backing plate 28, the upper side edge of the backing plate 28 is provided with a first recess 281 and a second recess 282 which are matched with the third gap 213 and the first gap 212 respectively, and the lower side edge of the backing plate 28 is provided with a third recess 283 which is matched with the second gap 211.

[0035] The main body 2 further comprises two vertical tension springs 26 which are arranged behind the upper clamping plate 23 and the lower clamping plate 22, in front of the cover 1 and symmetrically distributed left and right, and the two ends of each tension spring 26 are fixed on the upper clamping plate 23 and the lower clamping plate 22 respectively so that the upper clamping plate 23 and the lower clamping plate 22 always have a tendency to approach each other.

[0036] The left part of the upper side edge of the upper clamping plate 23 is upwardly formed with two protrusions 233 which are arranged left and right respectively, the dynamic pressure groove 27 is arranged between the two protrusions 233, and the dynamic pressure groove 27 is further connected with a transversely arranged guide rod 29 which is inserted therein, and the two ends of the guide rod 29 are fixed in the two protrusions 233 respectively.

[0037] The root of the dynamic pressure groove 27 is further formed with a rotation stop 271 which is located between the upper clamping plate 23 and the cover 1, and is used to prevent the dynamic pressure groove 27 from rotating when it is translated left and right.

[0038] The inner wall of the cover 1 is formed with two symmetrically arranged connecting portions 101 and a supporting portion 102 which is located between the two connecting portions 101, the bottom plate 21 is fixed between the two connecting portions 101, and the intersection of the first swing rod 24 and the second swing rod 25 is rotatably connected to the supporting portion 102.

[0039] Working principle:

[0040] The lower side edge of the cover 1 is rotatably connected to the lower side edge of the eye protection instrument 4, and a buckle switch is installed between the upper side edge of the cover 1 and the upper side edge of the front part of the eye protection instrument 4.

[0041] After the buckle switch is operated, the cover 1 can be swung forward and downward to open, then the fixed pressure groove 232 is slowly pushed upward by hand and the supporting groove 222 is pushed downward, which drives the upper clamping plate 23 and the lower clamping plate 22 to move upward and downward respectively, and then the distance between the fixed pressure groove 232 and the supporting groove 222 is increased, and then the mobile phone 3 can be inserted horizontally between the fixed pressure groove 232 and the supporting groove 222.

[0042] In the above process, the upper clamping plate 23 will drive the upper ends of the first swing lever 24 and the second swing lever 25 to approach each other and drive the first swing lever 24 and the second swing lever 25 to rotate in opposite directions when moving up by means of the two first transverse slot holes 231 and the first guide protruding column 241 and the second guide protruding column 251 located in the two first transverse slot holes 231 respectively; and the lower clamping plate 22 will drive the lower ends of the first swing lever 24 and the second swing lever 25 to approach each other and drive the first swing lever 24 and the second swing lever 25 to rotate in opposite directions when moving down by means of the two second transverse slot holes 221 and the first guide protruding column 241 and the second guide protruding column 251 located in the two second transverse slot holes 221 respectively, so that the synchronous centering movement effect of the upper clamping plate 23 and the lower clamping plate 22 is realized.

[0043] After the fixed pressure groove 232 and the support groove 222 are loosened, the upper clamping plate 23 and the lower clamping plate 22 will be reset and moved by means of the rebounding force of the two tension springs 26, and the dynamic pressure groove 27 will move synchronously with the upper clamping plate 23, so that the mobile phone 3 is clamped by the fixed pressure groove 232, the dynamic pressure groove 27 and the support groove 222, thereby completing the fixation of the mobile phone 3.

[0044] If the length of the mobile phone is relatively short, and the distance between the dynamic pressure groove 27 and the fixed pressure groove 232 is relatively large, the position of the dynamic pressure groove 27 can be pushed horizontally by hand to adjust the distance between the dynamic pressure groove 27 and the fixed pressure groove 232, so that the fixed pressure groove 232 can always press the mobile phone 3 according to the length of the mobile phone 3, thereby ensuring that the mobile phone 3 is clamped firmly and does not fall off.

[0045] Finally, the cover shell 1 is covered upwards and backwards, so that the mobile phone 3 is fixed in the eye protection instrument 4, and the screen of the mobile phone 3 is aligned backwards to the two view windows 41 in front of the eye protection instrument 4; then the eye protection instrument 4 is worn on the head of the user, and the eyes of the user can see the video images played on the screen of the mobile phone 3 in sequence through the two lens modules 42 and the two view windows 41.

[0046] The mobile phone 3 can be detachably fixed in the eye protection instrument, and the dismounting method is simple and convenient, so that the video images can be displayed by means of the electronic screen of the mobile phone 3, and a host computer for controlling the playing content and effect of the electronic screen is not needed outside the eye protection instrument, because the mobile phone 3 itself carries the above functions, and a data line is not needed, thereby greatly simplifying the structure of the eye protection instrument and reducing the cost; in addition, if the power of the mobile phone 3 is sufficient, the mobile phone 3 can be used for a long time without being plugged in, and the user can walk around at will without being limited near the power plug, thereby greatly facilitating the use.

[0047] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not limited to; although the present application is described in detail with reference to the foregoing examples, those skilled in the art should understand that it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
