[0022] In this embodiment of the invention, the transmission assembly 8 consists of a first rack 81, a gear 82, a second rack 83, and a spring 84. The gear 82 is rotatably connected to the inside of the charging housing 1 at its center and simultaneously meshes with the first rack 81 and the second rack 83 for transmission. The first rack 81 is slidably disposed inside the charging housing 1, and one end of the first rack 81 is connected to the pressing plate 7. The second rack 83 is installed at the bottom of the locking plate 5 and slidably connected to the inside of the charging housing 1. The side of the locking plate 5 away from the receiving groove 2 is connected to the charging housing 1 by the spring 84. The inner wall is installed by setting a first rack 81, a gear 82, a second rack 83, and a spring 84. Pushing the pressing plate 7 causes the first rack 81 to slide. The first rack 81 meshes with the gear 82, causing the gear 82 to rotate. The gear 82 causes the second rack 83 to slide. The second rack 83 causes the locking plate 5 to move on the limiting block 3. When the locking plate 5 moves towards the limiting block 3, the spring 84 is compressed, generating elastic force. After the pressing plate 7 is released, the elastic force acts on the locking plate 5, causing the locking plate 5 to abut against the inside of the locking groove 6.

[0023] In an embodiment of this utility model, the side of the charging case housing 1 is symmetrically provided with sliding holes 9. The two sliding holes 9 are corresponding in the length direction of the locking plate 5. The pressing plate 7 is slidably disposed inside the sliding holes 9. By providing the sliding holes 9, the stability of the sliding between the pressing plate 7 and the charging case housing 1 is improved.

[0024] In this embodiment of the utility model, the top two sides of the limiting block 3 are provided with upwardly extending baffles 10, the two sides of the locking plate 5 are located between the two baffles 10, and the bottom of the limiting block 3 is provided with a connecting hole 11 that communicates with the inside of the charging compartment housing 1. The bottom of the locking plate 5 is engaged with the connecting hole 11 in the vertical direction and passes through the connecting hole 11 to enter the inside of the charging compartment housing 1. By setting the baffles 10 and the connecting hole 11, the baffles 10 limit the locking plate 5 from the top two sides of the limiting block 3, thereby improving the stability of the locking plate 5 when sliding, and it passes through the connecting hole 11 to enter the inside of the charging compartment housing 1.

[0025] In an embodiment of this utility model, the first rack 81 is slidably connected to the limiting guide rail 12 disposed inside the charging case housing 1 in its length direction. By setting the limiting guide rail 12, the limiting guide rail 12 limits the first rack 81, thereby improving the stability of the sliding of the first rack 81.

[0026] In an embodiment of this utility model, the top of the charging case housing 1 is rotatably connected by a hinge to a top cover 13 for sealing the upper end of the charging case housing 1. By setting the top cover 13, the top cover 13 rotates on the upper end of the charging case housing 1, thereby improving the protection of the charging case housing 1 by covering the upper end of the charging case housing 1.

[0027] In an embodiment of this utility model, an anti-slip strip 14 is provided on the outer surface of the pressing plate 7. By providing the anti-slip strip 14, the friction force on the surface of the pressing plate 7 is increased, making it easier to push the pressing plate 7.

[0028] In an embodiment of this utility model, an indicator light 15 is provided on the front of the charging case housing 1. By providing the indicator light 15, the remaining power of the charging case can be displayed, making it easy for the user to monitor the power status.

[0029] In an embodiment of this utility model, a USB charging port 16 is also provided on the front of the charging case housing 1. By providing the USB charging port 16, the USB charging port 16 can be connected to an external power source, making it convenient to charge the charging case.

[0030] In this embodiment of the invention, the bottom of the locking plate 9 is not lower than the height of the Bluetooth headset when it is placed inside the receiving slot 2. By setting the above structure, it is ensured that when the Bluetooth headset is inside the receiving slot 2, the locking plate 5 is above the Bluetooth headset.

[0031] In use, first, rotate the top cover 13 to the top of the charging case housing 1, then hold the pressing plates 7 on both sides and press them towards the charging case housing 1. The pressing plates 7 drive the first rack 81 to slide on the limiting guide rail 12 through the sliding holes 9. The first rack 81 and the second rack 83 are engaged with the gear 82. The first rack 81 drives the gear 82 to rotate, thereby the gear 82 drives the second rack 83 to move. The second rack 83 drives the locking plate 5 to move on the limiting block 3, and the locking plate 5 moves towards the limiting block 3. When the spring 84 is compressed, it generates elastic force. At this time, the locking plate 5 moves onto the limiting block 3, maintaining the state of pressing the pressing plate 7. Simultaneously, the Bluetooth headset is placed into the receiving slot 2, and the Bluetooth headset is connected to the charging component. When the pressing plate 7 is released, the elastic force of the spring 84 acts on the locking plate 5, causing one end of the locking plate 5 to move into the locking slot 6. At this time, the locking plate 5 is above the Bluetooth headset and is connected to an external power source through the USB charging port 16 to charge the charging case. The remaining power is displayed by the indicator light 15.
