Including headset main body 1, the downside of headset main body 1 is set as ear casing 2, and the upper end of ear casing 2 is fixedly connected with damper box 4, adjusts
The inside of box 4 slidably connects adjusting rod 6 by the first sliding groove 9, and the inside of adjusting rod 6 is slotting through being connected with by adjustment hole 5
Bolt 48, the left end of plug 48 are equipped with limiting inserted block 47, and the upper and lower surface of limiting inserted block 47 is glued with jacking block 44 by fixing groove 41,
The upper end of jacking block 44 is fixedly connected with compressed spring 42, and jacking block 44 is slidably connected to sleeve 43, and the left end of limiting inserted block 47 is equipped with
Threaded rod 45, threaded rod 45 are threadedly connected to damper box 4 by threaded hole 46, and plug 48 is run through by through-hole 8 is connected to adjusting
Box 4, the right end of plug 48 are fixedly connected with knob 49, turn knob 49 counterclockwise, and the threaded rod 45 in left side passes through threaded hole 46
Rotation is exited to the right, and move right plug 48, and limiting inserted block 47 moves right and gives jacking block 44 upward power, and jacking block 44 is covering
Cylinder 43 in upward sliding, after plug 48 exits through-hole 8 completely to the right until, adjusting rod 6 is moved down by the first sliding groove 9,
Until hole 5 to be regulated and through-hole 8 are concentric, it is inserted into plug 48 to the left, and rotate clockwise knob 49 through through-hole 8, threaded rod 45
It locks plug 48 by threaded hole 46 and limits adjusting rod 6 and move, while compressed spring 42 can give jacking block 44 downward power,
Until treating that the lower end of jacking block 44 clings to the upper surface of limiting inserted block 47, it can be adjusted according to the head size of different users
6 up and down adjustment of pole is locked, and ensures that locking does not loosen while the clamping force of headphone has been effectively ensured, adjusting rod 6
Upper end is fixedly connected with ear arm 3, and head cover 7 is equipped at the top of the upper end of ear arm 3, when adjusting rod 6 can drive ear arm 3 to move down, band
Dynamic head cover 7 and slide plate 73 move down, and the head of user can give cushion 74 on slide plate 73 upward power, drive slide plate 73
72 inside upward sliding of second sliding slot, 71 compressive deformation of spring and by power inside it into row buffering, have when adjusting and clamping
It imitates to the power on head into row buffering, improves the comfort of headphone, slided inside the lower end of head cover 7 by second sliding slot 72
It is dynamic to be connected with slide plate 73, when slide plate 73 moves down, gag lever post 75 is driven to treat gag lever post in 76 inside slide downward of limiting slot
