By setting the limiting groove 5, the fixing groove 6, the card slot 7, the card block 8, the side plate 9, the card plate 10, the rotating groove 11, the threaded rod 12, the rotating groove and the groove 14, a better use effect is achieved. When in use, the battery body 1 is first placed inside the bottom plate 2, and then the cover plate 3 is aligned with the battery body 1 and pressed downward, and then the card block 8 is pushed inwardly corresponding to the upper card slot 7. When the card block 8 completely slides into the card slot 7, the turning handle 13 is pinched to rotate the threaded rod 12 corresponding to the upper rotating groove 11, so that the threaded rod 12 is completely rotated into the card block 8 through the rotating groove 11 and is rotated into the bottom plate 2 and the cover plate 3 through the fixing groove 6, thereby avoiding the existing battery pack due to the lack of a fixed structure. It is only fixed by welding with aluminum strips. After long-term use, it is easy to cause loose fixation due to aging of the aluminum strips. The limit grooves 5 are symmetrically distributed on the left and right ends of the cover plate 3 and the bottom plate 2, and the fixing grooves 6 are evenly distributed on the left and right ends of the bottom plate 2 and the cover plate 3, which is more convenient to fix through the fixing grooves 6 to prevent the situation in which the fixing effect is poor due to only fixing by the single-sided fixing groove 6 during use. The card block 8 is slidably connected to the bottom plate 2, and the card block 8 is slidably connected to the cover plate 3. The card blocks 8 are symmetrically distributed on the upper and lower ends of the back of the side plates 9, which is more convenient for the card blocks 8 to slide, and avoids the card blocks 8 being stuck by the bottom plate 2 or the cover plate 3 during use, which makes the card blocks 8 unable to continue to slide. When the sliding connection occurs, the side panels 9 are slidably connected to the bottom panel 2, the side panels 9 are slidably connected to the cover panel 3, the card panel 10 is slidably connected to the bottom panel 2, and the card panel 10 is slidably connected to the cover panel 3, which makes it easier for the side panels 9 to slide and prevents the side panels 9 from being stuck by the bottom panel 2 or the cover panel 3 during use, causing the side panels 9 to be unable to continue sliding. The threaded rod 12 is rotatably connected to the block 8, the threaded rod 12 is rotatably connected to the bottom panel 2, the threaded rod 12 is rotatably connected to the cover panel 3, and the turning handle 13 is rotatably connected to the groove 14, making it easier for the threaded rod 12 to rotate and preventing the threaded rod 12 from being stuck by the block 8 during use, causing the threaded rod 12 to be unable to continue rotating.

[0025] Embodiment 2

[0026] See also Figure 1-3The bottom end of the protective cover 15 is provided with a protective groove 17 to better protect the connector 4. When not in use, the protective cover 15 is contacted with the anti-skid pad 16 and the protective groove 17 at the bottom end of the protective cover 15 corresponds to the connector 4 and then pressed downward, so that the protective cover 15 can slide downward on the top of the connector 4 through the protective groove 17. When the bottom end of the protective cover 15 contacts the top of the cover plate 3, the protective cover 15 can be firmly stuck on the surface of the connector 4 through the protective groove 17, thereby preventing the connector 4 from being damaged and unable to be used due to collision when not in use. The protective cover 15 is slidably connected to the cover plate 3, and the anti-skid pads 16 are evenly distributed on the surface of the protective cover 15. The anti-skid pads 16 are slidably connected to the cover plate 3, which makes it easier for the protective cover 15 to slide, and avoids the protective cover 15 being stuck by the cover plate 3 during use, which causes the protective cover 15 to be unable to continue sliding.

[0027] Working principle: When in use, first place the battery body 1 inside the bottom plate 2, then match the cover plate 3 to the battery body 1 and press down. When the battery body 1 and the cover plate 3 are installed, pinch the side plate 9 to match the card block 8 to the card slot 7 and push it inward, so that the card block 8 slides inward on the surface of the bottom plate 2 and the cover plate 3 through the card slot 7. When the card block 8 completely slides into the card slot 7 and the back of the side plate 9 is in contact with the surface of the bottom plate 2 and the cover plate 3, the card plate 10 firmly clamps the bottom plate 2 and the cover plate 3 at the upper and lower ends of the battery body 1, and then pinch the turning handle 13 to match the threaded rod 12 to the rotating groove 11 and rotate it, so that the threaded rod 12 can rotate into the card block 8 through the rotating groove 11. When the threaded rod 12 is completely rotated into the inside of the card block 8, and the threaded rod 12 passes through the fixed groove 6 is completely rotated into the interior of the bottom plate 2 and the cover plate 3, and the turning handle 13 is rotated into the side of the bottom plate 2 and the cover plate 3 through the limiting groove 5, and the staff can also use a tool to tighten the threaded rod 12 and the turning handle 13 through the groove 14 to prevent the threaded rod 12 from falling off. When it is needed, the protective cover 15 is pinched and pulled upward by the anti-skid pad 16 to make the protective cover 15 slide upward on the surface of the connector 4 through the protective groove 17. When the protective cover 15 completely slides out of the surface of the connector 4, it can be connected for use, and when not in use, the protective cover 15 is pinched by the anti-skid pad 16 and the protective cover 15 is pressed downward corresponding to the upper connector 4 through the protective groove 17. When the bottom end of the protective cover 15 contacts the top end of the cover plate 3, it can be used, thereby preventing the connector 4 from being damaged and unusable due to collision with the connector 4 when not in use.
