When the adjusting bolt 24 is rotated, the upper retainer ring 23 and the lower retainer ring 25 lock the supporting block 22 to drive the spectacle frame 11 to move up and down synchronously. At the boundary between the adjusting pin 24 and the horizontal rotation adjusting part 3, a scale line can show the current height of the optical lens 7. The adjusting bolt can quickly realize high-precision height adjustment.

In some embodiments, the horizontal rotation adjustment section 3 includes a transfer stage 31. The middle part of the adapter 31 is provided with a groove 32, two circular arc notches 33 are arranged on the groove 32 in a penetrating mode, and the circular arc notches 33 are symmetrically distributed along two sides of the adapter 31. Note that the intrados of the two circular-arc notches 33 are opposite. A second fastening member 34 is provided in the circular arc notch 33, and the second fastening member 34 is used to fix the adaptor table 31 and the horizontal displacement adjusting portion 5. In the non-tightened state of the second fastening member 34, the screw portion of the second fastening member 34 can move along the arc direction of the circular-arc notch 33. The function of the recess 32 is to reduce the height of the head of the second fastener 34 so as not to interfere with the frame 11. The arc-shaped notch is easy for adjusting and fixing the placing angle of the optical lens.

In some embodiments, the height locking portion 4 includes a post 41 and a clamp 42. The column 41 is fixed to the relay table 31.

Alternatively, the clamping member 42 is integrally formed with the frame 11, and is more secure. The bottom surface of the clamping member 42 is flush with the bottom surface of the frame 11. In one example, in order to further enhance the fastening effect of the upright 41 and the clamping member 42, a sixth fastening member 44 is further disposed on the clamping member 42, and the sixth fastening member 44 directly abuts against the upright 41 after passing through one clamping piece. The clamping piece is easily adjusted and fixed, and is convenient to operate.

In some alternative embodiments, the bottom of the pillar 41 has an internally threaded hole, the adapter 31 has a second opening, and the pillar 41 is threadedly connected to the second opening by a fourth fastener 45. The head of the fourth fastener 45 is located below the adapter table 31.

In one example, the bottom surface of the displacement support 51 is rectangular, and the extension of the straight notch 54 in the length direction forms an angle smaller than 90 degrees with the bottom edge of the displacement support 51. In a preferred example, the extension of the straight slot 54 in the length direction makes an angle equal to 45 degrees with the bottom side of the displacement support 51. Therefore, the translation is more convenient. In one example, to avoid interference of the head of the fourth fastener 45 with the displacement seat 51, the side of the displacement seat below the fourth fastener 45 is provided with an arcuate concavity 55.
