[0018] The utility model is further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown, a plurality of battery mounting holes 2 are provided in the main shell 1, and a push-out piece 3 is provided on one side of the battery mounting hole 2. The push-out piece 3 is rotatably connected to the main shell 1 through a rotating shaft 4. When the push-out piece 3 rotates, one side of the push-out piece 3 extends into the battery mounting hole 2.

[0020] The push-out member 3 can be inserted into one side of the battery installation hole 2 and connected to one end of the push-out spring 5, and the other end of the push-out spring 5 is fixed on the main body bottom shell 6. When used, the push-out spring 5 plays a role of resetting.

[0021] A pressing shaft pressing plate 16 is provided on one side of the pressing ejection member 3 .

[0022] The pressing and ejecting member 3 includes a pressing portion 3-1, a connecting portion 3-2, and an ejecting portion 3-3 which are connected in sequence. The pressing portion 3-1 is located below the battery mounting hole 2, the connecting portion 3-2 is connected to the rotating shaft 4, and the ejecting portion 3-3 can extend into the battery mounting hole 2.

[0023] A charging mainboard 7 is provided on one side of the battery installation hole 2, and an indicator light 8 is provided on the charging mainboard 7. A battery 9 is provided in the battery installation hole 2, and the positive electrode of the battery 9 is connected to the positive electrode spring piece 10, and the negative electrode of the battery 9 is connected to the negative electrode spring piece 11.

[0024] A silicone ring 12 is provided on the surface of the main housing 1. Figure 3 As shown, the silicone ring 12 is located between the main body shell 1 and the main body upper shell 14, which plays a role in dust and water prevention and ensures that the charging of the battery is not affected.

[0025] One end of the main housing 1 is connected to the main upper housing 14 via a connecting hinge 13. The main housing 1 and the main upper housing 14 are locked by a buckle 15.
