[0028] Specifically: The lower end of the sliding cover 2 is fixedly connected with symmetrical extension rods 12, and the side of the extension rods 12 is fixedly connected with corresponding sliding columns 17. The outer shell 1 is fixedly connected with symmetrical sliding grooves 7, which are movably connected to the sliding columns 17 and can move stably along a specific trajectory.
[0029] Specifically: a symmetrical rotating seat 11 is fixedly connected inside the outer shell 1, and a symmetrical rotating shaft 18 is fixedly connected to one end of the lifting inclined plate 16. The rotating shaft 18 is movably connected to the rotating seat 11.
[0030] Specifically: The other end of the lifting inclined plate 16 is fixedly connected with symmetrical elastic locking posts 20, and the sliding cover 2 is fixedly connected with symmetrical limiting strips 22. The limiting strips 22 are provided with corresponding elastic locking grooves 23. The elastic locking posts 20 are movably connected to the limiting strips 22 and elastic locking grooves 23.

[0031] Specifically: a symmetrical constraint groove 8 is fixedly connected inside the outer shell 1, a spring-loaded locking post 20 is movably connected to the constraint groove 8, a pressure spring 21 is movably connected to the lower end of the spring-loaded locking post 20, and the other end of the pressure spring 21 is movably connected to the outer shell 1.
[0032] Specifically: symmetrical snap-fit strips 9 are fixedly connected inside the outer casing 1; a replaceable battery cell 19 is movably connected to the upper end of the lifting inclined plate 16; the replaceable battery cell 19 is movably connected to the snap-fit strips 9; multiple limiting plates 14 are fixedly connected to the side of the conduction block 13; the limiting plates 14 are movably connected to the outer casing 1; symmetrical interfaces 15 are fixedly connected to the side of the conduction block 13; a data cable 10 is fixedly connected to the other side of the conduction block 13; the data cable 10 is movably connected to the replaceable battery cell 19, thereby realizing data transmission and power conduction between the replaceable battery cell 19 and external devices.
[0033] Working principle:
[0034] The friction strip 3 at the upper end of the sliding cover 2 facilitates the application of force to push the sliding cover 2 to slide within the mounting position 6 at the upper end of the outer shell 1. When the sliding cover 2 slides, the sliding post 17 on the side of its lower extension rod 12 moves along the symmetrical sliding groove 7 inside the outer shell 1, ensuring that the sliding cover 2 slides stably along a specific trajectory. When the sliding cover 2 slides to the appropriate position, the latch 4 on the side of the outer shell 1 engages with the latch block 5 on the side of the sliding cover 2, preventing the sliding cover 2 from sliding accidentally. The sliding of the sliding cover 2 causes its internal limiting strip 22 to move, and the elastic groove 23 on the limiting strip 22 interacts with the elastic post 20 at the other end of the lifting inclined plate 16. The elastic post 20 is located in the constraint groove 8 inside the outer shell 1, and its lower end is connected to a pressure spring 21. During the sliding process of the sliding cover 2, the elastic post 20 moves within the elastic groove 23 and the constraint groove 8, and the pressure spring 21 acts as a buffer and reset mechanism, while simultaneously causing the lifting inclined plate 16 to rotate around the rotation axis 18 on the rotating seat 11. When a battery cell needs to be replaced, sliding cover 2 moves the inclined plate 16, causing the replaceable battery cell 19 to disengage from the locking strip 9, making it easy to remove the old battery cell and replace it with a new one. After installing the new battery cell, sliding cover 2 is reversed to fix the replaceable battery cell 19 onto the locking strip 9. The limiting plate 14 on the side of the conductive block 13 restricts its position on the housing 1. The conductive block 13 is connected to the replaceable battery cell 19 via data cable 10, and the interface 15 on the side is used to connect to external devices, realizing data transmission and power conduction between the replaceable battery cell 19 and external devices, meeting the usage requirements of lithium batteries.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
