The cross section of the first connecting part is arc-shaped, and the cross section of the second connecting part is L-shaped.

The cross section of the inner ring of the first connecting portion is circular arc, and the cross section of the outer ring of the first connecting portion is polygonal.

The cover body comprises a cylinder body and a plug arranged at one end of the cylinder body, and the plug is embedded at one end of the cylinder body.

Wherein, the plug is completely embedded in the cylinder or exposed out of the cylinder by a preset distance.

The plug is a cylinder, or the plug is a cylinder and a top cover arranged on the cylinder.

Wherein, the inner ring of the cover body is regular polygon or circular.

The utility model also discloses a writing tool, which comprises a pen body and the pen cover, wherein the pen cover is buckled on the pen body.

The pen body is connected with the pen cover through a limiting structure, and the limiting structure is a threaded structure, a buckling structure or a magnetic attraction structure.

Compared with the prior art, the utility model has the beneficial effects that the connecting piece is arranged on the outer periphery of the cover body, so that the connecting piece forms the vent hole along the length direction of the cover body between the cover bodies, and when the cover body is buckled with the pen body in the use process, the ink leakage site from the cover body can not occur because one end of the cover body is in a closed state. The air vent that forms between connecting piece and the lid is located one side of lid, can not influence the leakproofness of lid self, can be under the condition of guaranteeing the lid and prevent leaking the black effect, in case the user takes place to mistake the condition of swallowing, can accomplish more effectual ventilation effect.
