[0038] In practical use, the socket can be fixed by the fixing plate 21 and the fixing bolt 22 to achieve a stable connection of the socket and facilitate operation.

[0039] Working principle: In use, the outer shell 1 forms an earphone jack via the connecting post 2 and the socket 3. When needed, the plug 9 is inserted into the socket 3. The semi-sliding ball 10 pushes the locking blade 7 and the limiting post 6 upward within the vertical groove 4. The return spring 8, fixed between the locking blade 7 and the baffle 5, is compressed. When the semi-sliding ball 10 misses the position of the locking blade 7, the locking blade 7 pops out of the vertical groove 4 under the action of the return spring 8, locking and fixing the plug 9 to prevent accidental detachment and reduce the risk of disconnection. When it is necessary to unplug the earphone plug 9, continue pushing the plug 9, causing the moving block 12 to push the locking blade 7 upward. Then, force is applied to pull out the plug 9. The moving block 12 can perfectly engage with the locking groove 11 within the semi-sliding ball 10. The overlapping surfaces form a slope, facilitating the upward movement of the locking blade 7 and its sliding out of the semi-sliding ball 10, thus enabling the release of the locking structure. The limiting block 13 restricts the displacement distance of the moving block 12, facilitating operation, preventing disconnection issues, and improving the user experience. The reinforcing sleeve 18 reinforces the connection between the connecting wire 17 and the plug 9, preventing disconnection due to prolonged use and extending service life. The anti-slip texture 19 increases the anti-slip properties of the reinforcing sleeve 18, making it easier for users to insert and remove the plug 9.
