Detailed Description

Referring to FIGS. 1-4; the utility model provides a double-end pencil lid, includes shell 1, pushes away 2, antiskid piece 3, metal blade 4, rubber gasket 5, pen-holder parcel piece 6, spacing protective shroud 7, its characterized in that: the penholder wrapping sheet 7 penetrates through the rubber gasket 5, the upper end of the penholder wrapping sheet 7 is directly embedded into the bottom of the shell 1, and the rubber gasket 5 is tightly glued with the bottom of the shell 1.

Furthermore, when the pencil needs to be switched to the pencil sharpening state, the double-end pencil cap is turned over, one end of the pencil sharpening port 11 is aligned to the pencil point of the pencil, the pencil is inserted, the anti-slip sheets 3 on the two sides of the pencil cap are pinched, and the pencil can be turned along the central axis of the shell 1 to complete the pencil sharpening process.

Further, when needing to switch to the protection nib state, rotate the double-end pen cover, aim at pencil nib position with 6 one end of pen-holder parcel piece, insert the pencil to the nib and dab rubber gasket 5, then hold between the fingers pen cover both sides anti-skidding gasket 3, the downward slip pushes away a 2, outside warping pen-holder parcel piece 6 receives the constraint effect of ring baffle 22 and inwards draws in, and then makes 6 pastes tight pencil outer walls of pen-holder parcel piece to fix pencil nib end in 6 intracavity of pen-holder parcel piece.
