The nose support 4 is integrated with the left frame 2 and the right frame 3 and connects the left frame 2 with the right frame 3. The left frame 2 and the right frame 3 respectively have outer surfaces 2(), 30 and inner surfaces 21, 31. Receiving passages 22, 32 are respectively defined between the outer surfaces 20, 30 and the inner surfaces 'l, 31 for accon1noclatitig eyeglasses 9. Soft pads 8 are unitarily formed with the innci surfaces 20, 30 of the left and the right frames 2, 3 to provide comfortable touch for a user. Engaging surfaces 23, 33 are respectively formed on outward sides of the left frame 2 and the right frame 3. A solid engaging block 24 unitarily and outwardly extends from a part of each of the engaging surfaces 23, 33. Each engaging block 24 defines a receiving hole 241 substantially through a center thereof for receiving a corresponding adjusting apparatus 5. In combination with Fig. 2, each engaging block 24 has a tongue 242 extending from a lower portion thereof for returning the adjusting apparatus 5. In combination with Fig. 7, each engaging block 24 further defines four L-shaped grooves 25 at corners adjacent to the engaging surfaces 23, 33.

[00161 Each adjusting apparatus 5 comprises a base 50, a cover 51 and a fixing axis 52. The base 50 has a first base wall 501, and a second base wall 502 and a third base wall 503 substantially perpendicularly depending from opposite edges of the first base wall 501. A first assembling post 504 is formed on an inner of the first base wall 501 and adjacent to an edge thereof far engaging with the receiving hole 241. An axis hole 50S is defined ëe .e through the second base wall 502 and the third base wall 503 for receiving e the fimag axis 52. Fastener holes 506 are defined in the first base wall 501 for movably receiving the head strap 6. The cover 51 has a first cover wall i. 511, and a second cover wall 512 and a third cover wall 513 substantially perpendicularly depending from opposite edges of the first cover wall 511.

A second assembling post 516 is formed on an inner of the first cover wall 511 and adjacent to an edge thereof for engaging with the receiving hole 241 from on the other side. A resilient button 514 is integrally formed with and projects outwardly from the first cover wall 511. A plurality of inclined projections 515 is formed on an outward surface of the resilient button 514 for enhancing friction. A pressure arm 521 is transversely fonned on substantially a side of the fixing axis 52. The pressure arm 521 has an arcuate side 522 for pressure the tongue 242 (refelTing to Fig 8), and a flat side 523 for abutting the resilient butto7i 514 A stop arm 524 is fond on the other side of the fixing axis 52 and has an inclined end 525 for abutting a stop slot 60 of a head strap 6 (shown in Fig. 8). With reference to Figs. 6 and 7, in assembly, the cover 51 is assembled with the base 50 to envelop the engaging block 24. The second base wall 502 and the third base wall 503 respectively define grooves 507 in inward sides thereof. The second cover wall 512 and the third cover wall 513 respectively form latches 508 at inward sides thereof for latching with the grooves 507. L-shaped locking ribs 509 are formed respectively on the base 50 and the cover 51 and are corresponding to the Ushaped grooves 25 of the engaging blocks 24 for further retaining the base 50 and the cover 51 together.

7] With reference to Figs. 3-5, in assembly, the adjusting apparatuses are respectively assembled on outward sides of the left frame 2 and the rift frame 3. The resilient buttons 514 of the adjusting apparatuses 5 project slightly beyond the first cover wall 511 of the cover 51. Referring to Figs. 1 and 8, the fixing axis 52 is pivotably received in the axis hole 505.
