The opening of the C-shaped elastic sheet 18 faces the telescopic part 2, and the end part of the C-shaped elastic sheet 18 is convexly provided with a semi-cylinder 19 which is matched with the semi-circular groove 16. When the telescopic part 2 slides in the sliding groove 15, the front leg part 1 and the sliding part move relatively, so that the whole length of the adjustable glasses leg is changed, the positions of the hook ear piece 5 and the ears are changed, and the hook ear piece 5 is tightly attached to the rear of the ears. The sliding telescopic part 2 is positioned by clamping the semi-cylinder 19 at the end part of the C-shaped elastic sheet 18 with the semi-circular groove 16 on the side wall of the chute 15, so that the sliding telescopic part 2 can stably stay, unexpected sliding can not occur, and the use stability is ensured.

As shown in fig. 3, in order to avoid the unstable clamping between the semi-cylinder 19 and the semi-circular groove 16 caused by long-term use of the C-shaped elastic sheet 18, the positioning table 17 is provided with a positioning hole 23, the inner wall of the C-shaped elastic sheet 18 corresponding to the semi-cylinder 19 is provided with a safety spring 22, and the other end of the safety spring 22 extends into the positioning hole 23 to abut against the bottom of the positioning hole 23. The C-shaped elastic sheet 18 is pushed by the safety spring 22, so that when the C-shaped elastic sheet 18 is subjected to plastic deformation after long-term use, the clamping connection of the semi-cylinder 19 and the semi-circular groove 16 is still stable, and the service life of the glasses leg body is prolonged.

As shown in fig. 4, in order to avoid separation of the telescopic part 2 from the front leg part 1 during the relative movement, the use is inconvenient. The side wall of the chute 15 is provided with a limit groove 20, and the side wall of the telescopic part 2 is provided with a limit column 21 which is in sliding connection with the limit groove 20.

Specific embodiments of an adjustable temple: in a severe sport scene, a user can rotate the hook ear piece 5 in the accommodating groove 4 out of the accommodating groove 4 around the axis of the hinge joint of the hook ear piece 5 and the inner wall of the accommodating groove 4, and the ratchet 6 at the hinge joint end of the hook ear piece is driven to rotate while the hook ear piece 5 rotates. Because the top of the pawl 8 is provided with the abutting spring 9, a movable space is arranged above the pawl 8, so that when the hook ear piece 5 rotates out of the accommodating groove 4, the ratchet 6 pushes the pawl 8 to move towards the abutting spring 9, and the rotation out of the hook ear piece 5 is not limited. Because the side wall of the pawl 8 always abuts against the side wall of the positioning groove 7 by abutting against the spring 9, the ratchet 6 cannot reversely rotate, the hook ear piece 5 cannot rotate after rotating out, the hook ear piece can always be attached to the rear of the ear, the position limitation of the hook ear piece and the rear of the ear is utilized, the phenomenon that the glasses leg is not easy to slide down from the upper parts of the ears is avoided, and the glasses are protected from being damaged.

If the hook ear 5 is not tightly attached to the rear of the ear after being rotated out of the accommodating groove 4, and is uncomfortable enough, the telescopic part 2 can be forced to slide in the sliding groove 15, so that the front leg part 1 and the sliding part can move relatively. Meanwhile, the semi-cylinder 19 at the end part of the C-shaped elastic sheet 18 moves in the semicircular groove 16, so that the whole length of the adjustable glasses leg is changed, the positions of the hook ear piece 5 and the ears are changed, and the hook ear piece 5 is tightly attached to the rear of the ears and is more comfortable.

After the movement is finished, a user can push the loose-claw sliding block 11 to be away from the ratchet 6, and the loose-claw sliding block 11 drives the shifting plate 10 to rotate around the hinge axis of the pawl 8, so that the pawl 8 is driven to be away from the ratchet 6, and the compression force of the abutting spring 9 is exerted. At this time, since the pawl 8 is separated from the ratchet 6, the user can retract the tab member 5 into the accommodating groove 4 so that the first magnet 13 and the second magnet 14 are attracted. The release pawl slider 11 is then brought close to the ratchet teeth 6 such that the abutment spring 9 releases the spring force, causing the pawl 8 to reengage the ratchet teeth 6.

Of course, the above is only a typical example of the utility model, and other embodiments of the utility model are also possible, and all technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of the utility model claimed.
