that the similarity with eyeballs is improved, eye protection propaganda is convenient to carry out, when the lens 23 is inserted into the first annular clamping groove 17, the second annular clamping groove 18 and the lower fixing box 41 by a user, the grabbing place is generally the top of the lens 23 exposed out of the lower fixing box 41, so that stains are left on the lens 23 after the lens 23 is used for many times, when the upper shell 12 is covered, the cleaning cotton ring 8 cleans the lens 23, so that the stains on the lens 23 are removed, when the lens 23 is used, the lens 23 is made of glass, meanwhile, the lens 23 is placed in the lower fixing box 41, only the top is exposed, the contact area of fingers is small when the lens is taken, and thus slipping occurs, when the lens is used, the user presses the push rod 81 by fingers, so that the push rod 82 is driven to push the first support rod 85 to rotate, then the first rotating shaft slides in the sliding groove 91, so that the connecting plate 84 slides downwards, and the first support rod 85 and the second support rod 86 are folded, the lens 23 is circular, can extrude lens 23 in the fixed box 41 down during the extrusion, make its middle part also can expose, thereby can be convenient for the user take lens 23, thereby the user's use, the position that the user snatched lens 23 is under the general condition all is the top of lens 23, simultaneously the top of lens 23 exposes at the fixed box 41 top down, therefore the top of lens 23 has a large amount of stains, pour into cleaning solution into the fixed box 41 down earlier, when first branch 85 rotates, first pivot can carry out horizontal direction and remove in spout 91, thereby drive gear 92 and remove, through cooperating with rack 93, with this drive first pivot rotates, thereby drive rubber wheel 87 and rotate, can drive lens 23 through frictional force when rubber wheel 87 rotates, thereby rotate lens 23 into fixed box 41 down, then under the effect of cleaning cotton 94, thereby improve the cleaning effect of lens 23, further avoid reducing the bacterium on the lens 23, improve the sanitation cotton 94 and can be located fixed in the fixed box and carry out the cleaning solution in the place of sliding connection in the sliding seal ring 41 when lens 23 is taken out simultaneously, the problem of the whole is located in the fixed box is located, the cleaning effect is improved, the sliding is provided for the sealing ring 81 has occurred.
