[0006] Preferably, the driving mechanism includes a lever movably inserted inside the fixed seat, and a return spring is movably sleeved on the outer surface of the lever. The position of the limiting slide can be adjusted through the driving mechanism so that it cooperates with the arc-shaped rubber pad to stably limit the retaining ring, thereby limiting the insertion rod, and the top of the return spring is fixedly connected to the top of the inner wall of the fixed seat.

[0007] Preferably, a pull button is provided on the top of the lever, and a bottom shaft is fixedly penetrated through the bottom end of the lever.

[0008] Preferably, the outer surface of the bottom shaft is rotatably connected to a driving bar, and the bottom end of the driving bar is rotatably connected to a coupling shaft.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figure 1-4 A portable Bluetooth headset comprises an earmuff 1, the outer surface of the earmuff 1 is fixedly connected to a fixing seat 2, a plug rod 3 is movably inserted on the top of the fixing seat 2, an earphone holder 4 is arranged on the top of the plug rod 3, a retaining ring 5 is fixedly sleeved on the outer surface of the plug rod 3, a guide rail 6 is fixedly installed inside the fixing seat 2, a slot 7 is opened on the outer surface of the guide rail 6, a limiting slide 8 is slidably connected to the inner side of the guide rail 6, an arc-shaped rubber pad 9 is arranged on the arc-shaped inner wall of the limiting slide 8, and a driving mechanism is arranged inside the fixing seat 2.

[0021] Through the above technical solution, the device can insert the insertion rod 3 into the slot 7 of the internal guide rail 6 of the fixed seat 2 during use, and cooperate with the driving mechanism to adjust the position of the limiting slide 8, and cooperate with the arc-shaped rubber pad 9 to stably limit the retaining ring 5, thereby stabilizing the insertion rod 3, that is, the earphone frame 4 is stably connected to the earmuff 1.

[0022] Specifically, the driving mechanism includes a lever 10 movably inserted into the fixing seat 2 , and a return spring 11 is movably sleeved on the outer surface of the lever 10 .

[0023] Through the above technical solution, the top of the reset spring 11 is fixedly connected to the top of the inner wall of the fixed seat 2. Under the limiting action of the reset spring 11, it can stabilize the lever 10 at the corresponding position through the bottom shaft 13, and indirectly link the limiting slide 8 to stably clamp the retaining ring 5.

[0024] Specifically, a pull button 12 is provided on the top of the lever 10 , and a bottom shaft 13 is fixedly penetrated through the bottom end of the lever 10 .

[0025] Through the above technical solution, pulling the pull button 12 can pull the lever 10 upward, thereby compressing the return spring 11.

[0026] Specifically, the outer surface of the bottom shaft 13 is rotatably connected to a driving bar 14 , and the bottom end of the driving bar 14 is rotatably connected to a coupling shaft 15 .

[0027] Through the above technical solution, when the lever 10 is pulled upward, the driving bar 14 will rotate along the bottom shaft 13 and deflect.

[0028] Specifically, a fixed inner rod 16 is fixedly connected inside the fixed seat 2 , a swing bar 17 is rotatably connected to the outer surface of the fixed inner rod 16 , and one end of the swing bar 17 away from the fixed inner rod 16 is rotatably connected to the outer surface of the coupling 15 .

[0029] Through the above technical solution, the driving bar 14 will drive the swing bar 17 and the driven bar 18 through the coupling 15 during the deflection process, so that they can deflect accordingly.

[0030] Specifically, the outer surface of the coupling shaft 15 is rotatably connected with a driven bar 18 , and a frame shaft 19 is fixedly penetrated through the inner side of the limiting slide 8 , and the outer surface of the frame shaft 19 is rotatably connected with an end of the driven bar 18 away from the coupling shaft 15 .

[0031] Through the above technical solution, the driven bar 18 can rotate along the frame shaft 19 after being deflected, and drive the limiting slide 8 through the frame shaft 19, so that the retaining ring 5 is limited or separated from it through the limiting slide 8.

[0032] Working principle: When the head-mounted Bluetooth headset is in use, the insertion rod 3 can be inserted into the fixed seat 2. At this time, the insertion rod 3 will be inserted into the slot 7 on the surface of the guide rail 6. Under the reset action of the reset spring 11, it will press against the bottom shaft 13 to move the lever 10 downward, so that the driving bar 14 rotates along the bottom shaft 13, and at the same time, the swing bar 17 and the driven bar 18 are driven by the coupling 15. During this process, the swing bar 17 will swing along the fixed inner rod 16, and the driven bar 18 will rotate along the frame shaft 19, and the limit slide 8 will be driven by the frame shaft 19, so that the limit slide 8 slides along the inner side of the guide rail 6 to approach the insertion rod 3 until the arc surface of the limit slide 8 cooperates with the arc rubber pad 9 to stably clamp on the retaining ring 5. , so that the retaining ring 5 remains stable, and then the insertion rod 3 is stably inserted in the fixing seat 2, that is, the earphone holder 4 is stably connected to the earmuff 1. When the Bluetooth headset is stored, the earphone holder 4 and the earmuff 1 can be separated, which is convenient for carrying the headset. At this time, the pull button 12 can be lifted to drive the lever 10 to pull up. During this process, the return spring 11 is compressed, and the bottom shaft 13 will pull the driving bar 14 up, and at the same time, the swing bar 17 and the driven bar 18 are pulled through the coupling shaft 15 at the bottom. At this time, the driven bar 18 will pull the limiting slide 8 through the frame shaft 19, so that it gradually moves away from the insertion rod 3, and the retaining ring 5 is no longer stably positioned. The insertion rod 3 can be easily pulled out, and the earphone holder 4 and the earmuff 1 are separated, so that the headset can be carried.
