In the example shown in fig. 1, the base body 10 is a cylindrical structure, and includes a cylindrical section with a larger diameter and a cylindrical section with a smaller diameter, wherein the cylindrical section with the larger diameter is used as the large end 11 of the base body 10, and the cylindrical section with the smaller diameter is used as the small end 12 of the base body 10.

Referring to fig. 2, fig. 2 shows a cross-sectional view of a plugging tool for a battery pack connection hole according to an exemplary embodiment of the present application. The interior of the base body 10 is a hollow structure, the movable rod 20 is inserted into the hollow structure, one end of the movable rod 20 is a tapered end 21, the tapered end 21 faces the small end 12 of the base body 10, and the other end of the movable rod 20 faces the large end 11 of the base body 10 and is connected with the handle 30.

The handle 30 has a lifting and pressing stroke, and during the lifting and pressing stroke of the handle 30, the movable rod 20 can be driven to move in the hollow structure relative to the base body 10, so that the tapered end 21 is driven to extend and retract in the hollow structure.

In one example, the handle 30 includes a first link 31 and a second link 32, one end of the first link 31 is a grip 33 for being grasped by a human hand, and the other end of the first link 31 is hinged to the movable rod 20.
