When in use:

the principle of the embodiment is as follows:

when the pulling block 42 is pulled upwards, the bottom end of the pulling block 42 rotates downwards and simultaneously presses the spring plate 47, the inclined plane 422 of the pulling block 42 close to the left side plate 412 is tightly pressed against the top end plane of the spring plate 47 in the pressing process, at this time, the first supporting leaves 46 are lifted up, otherwise, when the pulling block 42 is pulled downwards, the bottom end of the pulling block 42 rotates upwards and simultaneously presses the spring plate 47, the inclined plane 422 of the pulling block 42 close to the right side plate 413 is tightly pressed against the top end plane of the spring plate 47 in the pressing process, at this time, the height of the first supporting leaves 46 is reduced, therefore, the height of the first supporting leaves 46 on two sides can be raised by pulling the pulling block 42 upwards, otherwise, the height of the first supporting leaves 46 on two sides can be reduced by pulling the pulling block 42 downwards, the first supporting leaves 46 can be fixed on different positions on the nose by adjusting the height of the first supporting leaves 46, when the spectacles are worn, the height of the first supporting leaves 46 can be adjusted back and forth, avoid because the support leaf can not adjust and carry out long-time extrusion to the same position on the nose and the impression appears, and then cause the harm that the impression department is painful or the skin is ground.

The principle of the second embodiment is as follows:

tensile stalk 52 passes through card 55 and tensile pipe 51 sliding connection from top to bottom the in-process of pull, through the height that tensile stalk 52 of pull changes second support leaf 57, and then changes the fixed position of second support leaf 57 on the nose, consequently can adjust the fixed position of second support leaf 57 on the nose through tensile stalk 52 of pull in the wearing glasses in-process, avoid because the support leaf can not adjust and carry out long-time extrusion to the same position on the nose and appear the impression, and then cause the painful harm that perhaps grinds the skin in impression department.

The third principle of the example is as follows:

the first movable nose pad 61 is mounted on the spectacle frame 1 by pressing and clamping the spectacle beam 1B into the first clamping groove 612, and the third movable nose pad 614 is fixed at a higher position on the nose after the first movable nose pad 61 is mounted on the spectacle frame 1 because the second pad stem 613 is shorter in length; the movable nose of second holds in the palm 62 through pressing into in the second draw-in groove 622 and chucking with glasses crossbeam 1B, realize that the movable nose of second holds in the palm 62 and installs on spectacle frame 1, because the length of third support leaf stalk 623 is longer, install the movable nose of second and hold in the palm 62 after on spectacle frame 1, the lower position on the nose is fixed to fourth support leaf 624, hold in the palm the change of making a round trip between 61 and the movable nose of second through first movable nose, can adjust the position of installing the support leaf on the nose, avoid because the support leaf can not adjust and carry out long-time extrusion to the same position on the nose and appear the impression, and then cause the painful harm of or the broken skin of impression department.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
