[0032] The protection mechanism includes a first fixed block 103, and the first fixed block 103 is fixed to the side of the first connecting shell 101, a rotating block 104 is rotated inside the first fixed block 103, a bolt 105 is fixed on the top of the rotating block 104, and a threaded block 106 is threadedly connected to the side of the bolt 105, a second fixed block 107 is fixed to the side of the second connecting shell 102, and a positioning groove 108 is provided on the side of the second fixed block 107, and an insert block 109 is fixed inside the first connecting shell 101 and the second connecting shell 102, and a slot 110 is provided at the bottom and top of the electric board module 1 and the protective cover 2. Before using the battery protection board, moving the first connecting shell 101 and the second connecting shell 102 can drive the insert block 109 to move, and the insert block 109 moves to the slot 110. After the insert block 109 is inserted into the slot 110, the second fixing block 107 can be moved to the top of the first fixing block 103. At this time, pushing the bolt 105 can drive the rotating block 104 to rotate inside the first fixing block 103. When the bolt 105 rotates, the threaded block 106 can be driven to rotate. After the bolt 105 rotates to the inside of the positioning groove 108, the threaded block 106 is rotated. When the threaded block 106 rotates, it slides with the bolt 105. When the threaded block 106 slides to the top of the second fixing block 107, it can be squeezed. When the threaded block 106 is squeezed, the second connecting shell 102 can be driven to position with the first connecting shell 101.

[0033] Embodiment 2:

[0034] like Figure 5 and Figure 6 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the surface nut of the fixing component 3 of the device will loosen after long-term use, resulting in unstable connection of the device, a limiting mechanism is disclosed:

The guide block 207 is fixed on the inner side of the L-shaped block 205. When the limiting mechanism of the device positions the nut of the fixed component 3, the sliding of the L-shaped block 205 can drive the guide block 207 to move. When the guide block 207 moves, it can slide through the guide groove 206. When the L-shaped block 205 is subjected to the extrusion force of the nut, the L-shaped block 205 can drive the guide block 207 to squeeze the inner wall of the guide groove 206. The guide block 207 can prevent the L-shaped block 205 from being deformed when subjected to force. At the same time, the guide block 207 can improve the positioning strength of the L-shaped block 205, and further improve the stability of the connection between the protective cover 2 and the electric board module 1.
