Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, the utility model discloses a healthy reading and writing position of sitting guiding device of optics, it includes C type support 1, guide pillar 8, magnifying glass fixed plate 6, magnifying glass 7, backup pad 2 and the reflection assembly that sets gradually from the bottom up. The lower end of the guide post 8 is fixed on the top of the C-shaped bracket 1, and the upper end is fixed with the support plate 2. The magnifier 7 is fixed on the magnifier fixing plate 6, and the magnifier fixing plate 6 is arranged in the middle of the guide post 8 in a vertically adjustable manner. Windows 12 for viewing are respectively arranged at the top of the C-shaped support 1 and in the middle of the supporting plate 2, so that objects on a desktop can be imaged on the reflecting component. The magnifier fixing plate 6 is in transition fit with the guide post 8, and a jackscrew 9 for fixing is arranged on the side edge of the magnifier fixing plate 6. The height of the magnifier fixing plate 6 can be adjusted to the designated height after the jackscrew 9 is unscrewed, and the magnifier fixing plate can be fixed by screwing the jackscrew 9.

The reflection assembly comprises a first plane mirror 3, a connection plate 4 and a second plane mirror 5. One end of the first plane mirror 3 is fixedly connected with one end of the support plate 2, the other end is fixedly connected with one end of the second plane mirror 5 through the connecting plate 4, and the included angle alpha between the first plane mirror 3 and the support plate 2 is 105-115 degrees. The sum of the angle β of the connecting plate 4 to the first flat mirror 3 and the angle θ of the connecting plate 4 to the second flat mirror 5 is between 220 ° and 230 °, and the sum of the angles β and θ is preferably 225 °. The angle alpha is preferably 115 deg., the second plane mirror makes an angle gamma of 110 deg. with the vertical. After the reflection of the first plane mirror 3 and the second plane mirror 5, the desktop can be imaged on the first plane mirror 3.

The guide post 8 includes an upper guide post 81, a lower guide post 82 and a fixing nut 83. The upper guide post 81 is telescopically sleeved on the lower guide post 82, and the fixing nut 83 is arranged at the joint of the upper guide post 81 and the lower guide post 82. The magnifier fixing plate 6 is disposed on the lower guide post 82, and the support plate 2 is fixed on the upper end of the upper guide post 81. When the length of the guide post 8 is adjusted, the fixing nut 83 is loosened, the upper guide post 81 and the lower guide post 82 can be adjusted in a telescopic manner, and after the upper guide post 81 and the lower guide post 82 are adjusted to a proper height, the fixing nut 83 is screwed, so that the upper guide post 81 and the lower guide post 82 are mutually fixed.
