At this time, the installation is completed, and the moving lever makes the two connecting blocks 31 withdraw from the protective cover limit block 32 to open the protective cover 8.

[0027] In addition, a guide groove is provided at the bottom of the battery slot 13, and the slider 26 is slidably inserted in the guide groove, so that the horizontal sliding process of the slider 26 can be guided. An adjusting slide hole 28 is provided at the bottom of the mounting rod 14, and an adaptor shaft is connected to the top of the slider 26, and the adaptor shaft can be slidably arranged in the adjusting slide hole 28. The vertical displacement of the bottom end of the mounting rod 14 during the rotation of the mounting rod 14 is offset by the sliding of the adaptor shaft relative to the mounting rod 14 in the adjusting slide hole 28.

[0029] Working principle: when the battery 7 is placed in the battery slot 13, it will slide down against the lower pressure plate 11. In this process, the connecting rod 12 drives the two sliders 26 to slide in opposite directions and drives the installation rod 14 to rotate with the central axis 16 as the axis. At this time, the battery limit block 30 can slide to the top of the battery 7, and the ratchet 15 is restricted by the pawl 35 and cannot be reversed, that is, the battery limit block 30 cannot slide in the opposite direction to separate from the battery 7. When the battery 7 is placed in the battery slot 13, the staff presses the connecting block 31 with their hands. When the protective cover 8 covers the top of the battery box 3 to close the battery slot 13, the connecting block 31 will be inserted into the protective cover 8 in the protective cover limit block 32 through the positioning spring in the battery limit block 30. At this time, the installation is completed.

[0030] When disassembling, it is necessary to use a key to open the hidden cover 4, unlock the lock on the blocking bar 24, and turn the stud 25 to make the cross plate 23 drive the two adjusting rods 33 to slide horizontally. At this time, the ratchet 15 and the pawl 35 are staggered, and the ratchet 15 can be reversed. The lever is also moved to make the two connecting blocks 31 withdraw from the protective cover limit block 32 to open the protective cover 8, and then the battery limit block 30 is pushed to both sides to reverse the installation rod 14. At this time, the battery 7 can be taken out of the battery slot 13. The battery 7 is protected by multiple protective structures, and the effect is better. The structure can be applied to normal batteries 7, and the scope of application is wider.
