Specific embodiment
The utility model is further described with reference to embodiment, this is the preferred embodiment of the utility model.
As shown in Figs. 1-5, a kind of shaft, including first rotating shaft 1, the second shaft 2, first support 3 and arranged on described
The second support 4 of one stent, 3 inside.One end of the first support 3 and one end of the second support 4 are respectively equipped with the first company
Hole is connect, the other end of the first support 3 and the other end of the second support 4 are respectively equipped with the second connecting hole；Described first
Shaft 1 and second shaft 2 are inserted into first connecting hole and second connecting hole respectively；The first support 3 and institute
Second support 4 is stated to be rotatablely connected by the first rotating shaft 1 and second shaft 2.The connecting pin of the first rotating shaft 1 is equipped with
The axis connection hole 11 is inserted into axis connection hole 11, the connecting pin of second shaft 2.It is arranged with successively in second shaft 2
Adjusting nut 21, elastic component 22 and the change 23 of connection, the change 23 are connected with the second support, and the one of the change 23
Side is equipped with boss 231, and the second support 4 is equipped at least two and the 231 corresponding groove 41 of boss；Described first
The outside of shaft 1 and second shaft 2 is arranged with the first dirt-proof boot 5 and the second dirt-proof boot 6 respectively.
During the work of the shaft, first support 3 and second support 4 are installed respectively on the head hoop and earplug of earphone, rotate ear
During plug, second support 4 is driven to rotate, since the second shaft 2 and second support 4 are rotatablely connected, when second support 4 rotates, second
Relative motion occurs for change 23 and second support 4 in shaft 2, and the boss 231 in change 23 is made to be skidded off from a groove 41,
