[0021] A retractable Bluetooth headset comprises an earphone head 1 and an earphone handle 2. An L-shaped fixing rod 4 is detachably mounted on the bottom end of the earphone handle 2. An L-shaped telescopic rod 7 is movably arranged inside the L-shaped fixing rod 4. A compression spring 6 is arranged at the end of the L-shaped telescopic rod 7. A rectangular box 8 is fixedly arranged at the end of the L-shaped telescopic rod 7 away from the compression spring 6. A pressure plate 9 is movably arranged inside the rectangular box 8. A stud 10 is arranged on the side of the pressure plate 9. A knob 11 is fixedly arranged at the end of the stud 10 away from the pressure plate 9.

[0022] Specifically, when you need to wear a Bluetooth headset, manually pre-rotate the end of the L-shaped fixing rod 4 into the bottom end of the earphone handle 2, and then manually move the L-shaped telescopic rod 7 outward a certain distance relative to the L-shaped fixing rod 4, driving the pressure plate 9 in the rectangular box 8 to move a certain distance away from the earphone handle 2. At this time, the compression spring 6 is stretched, and then the L-shaped fixing rod 4 is manually rotated and tightened relative to the earphone handle 2. After tightening, the L-shaped telescopic rod 7 is released. The L-shaped telescopic rod 7 drives the pressure plate 9 to reset under the pull of the compression spring 6 to restore its deformation. Then, when wearing, first engage the earlobe between the earphone handle 2 and the pressure plate 9, and then insert the earphone head 1 into the ear hole. If the earlobe is large, the pressure plate 9 clamps the earlobe under the action of the compression spring 6. If the earlobe is small and an interval occurs, you can turn the knob 11 to drive the stud 10 to rotate, and then push the pressure plate 9 to move linearly and clamp the earlobe. The purpose of this design is that the L-shaped telescopic rod 7 can be extended and retracted under the force of the compression spring 6 to drive the pressure plate 9 to clamp the larger earlobe, and the stud 10 is used to rotate and drive the pressure plate 9 to move to clamp the smaller earlobe, thereby reinforcing the position of the earphone head 1 behind the ear to prevent it from falling off.

[0028] The outer side of the pressure plate 9 is slidingly connected to the inner side of the rectangular box 8, the stud 10 is threadedly connected to the inner side wall of the rectangular box 8, and the outer side of the end of the stud 10 away from the knob 11 is rotatably connected to the inner side of the pressure plate 9 through a bearing. The purpose of this design is to ensure that the rotation of the knob 11 drives the stud 10 to rotate, and the rotation of the stud 10 drives the pressure plate 9 to reciprocate along a straight line for extension and contraction.

[0029] Further, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0030] A number of evenly distributed anti-slip protrusions 12 are fixedly provided on the outer circumference of the knob 11 . The purpose of this design is to improve the anti-slip performance and facilitate the rotation of the stud 10 by the knob 11 .

[0033] To sum up: when you need to wear a Bluetooth headset, manually pre-rotate the end of the L-shaped fixing rod 4 into the bottom end of the earphone handle 2, and then manually move the L-shaped telescopic rod 7 outward a certain distance relative to the L-shaped fixing rod 4, driving the pressure plate 9 in the rectangular box 8 to move a certain distance away from the earphone handle 2. At this time, the compression spring 6 is stretched, and then manually rotate the L-shaped fixing rod 4 relative to the earphone handle 2 and tighten it. After tightening, release the L-shaped telescopic rod 7. The L-shaped telescopic rod 7 drives the pressure plate 9 to reset under the pull of the compression spring 6 to recover its deformation. Then when wearing it, first engage the earlobe between the earphone handle 2 and the pressure plate 9, and then insert the earphone head 1 into the ear hole. If the earlobe is large, the pressure plate 9 clamps the earlobe under the action of the compression spring 6. If the earlobe is small and an interval occurs, you can turn the knob 11 to drive the stud 10 to rotate, and then push the pressure plate 9 to move linearly and clamp the earlobe. The purpose of this design is that the L-shaped telescopic rod 7 can be extended and retracted under the force of the compression spring 6 to drive the pressure plate 9 to clamp the larger earlobe, and the stud 10 is used to rotate and drive the pressure plate 9 to move to clamp the smaller earlobe, thereby reinforcing the position of the earphone head 1 behind the ear to prevent it from falling off.
