[0042] For further information, see Figure 3 A plurality of second plug-ins 110 that cooperate with the first slots 212 are provided on one side of the host 100 close to the battery pack 200 .

[0043] Specifically, the second plug-in 110 and the first slot 212 are used in combination to achieve stability of the connection between the host 100 and the battery pack 200; the second plug-in 110 at the lower end of the host 100 extends into the first slot 212 at the upper end of the battery pack 200, thereby achieving positioning and connection between the host 100 and the battery pack 200.

[0044] For further information, see Figure 3 and Figure 6 The end of the first plug-in 211 away from the host 100 is a curved surface structure 213 .

[0045] It should be noted that the end of the first plug-in 211 away from the host 100 is a curved surface structure 213 , that is, the end of the first plug-in 211 close to the base 300 is a curved surface structure 213 , which reduces the mutual force influence between the first plug-in 211 and the first slot 212 .
