[0005] As a preferred technical scheme of the above, the limiting portion is provided with a plurality of limiting bosses.

[0006] As a preferred technical scheme of the above, the limiting boss comprises a first limiting boss arranged at the lower opening of the limiting portion, and the first limiting boss is used for limiting the pen tip slot portion of the marker pen.

[0007] As a preferred technical scheme of the above, the limiting boss comprises a second limiting boss arranged at the middle portion of the limiting portion, and the second limiting boss is used for limiting the pen mouth of the marker pen.

[0008] As a preferred technical scheme of the above, the limiting portion is symmetrically provided with a notch slot, and the notch slot is upward from the lower opening of the limiting portion and penetrates through the first limiting boss.

[0009] As a preferred technical scheme of the above, the inner cover is buckle-connected with the upper side surface of the ink bottle, and is sealingly connected with the top edge of the ink bottle.

[0010] As the preferred technical scheme of the above, the bottle cap is screwed on the ink bottle and extrudes the sealing connection between the inner cap and the ink bottle.

[0011] As the preferred technical scheme of the above, the bottle cap top center extends downward to form a convex column, and when the bottle cap is screwed on the ink bottle, the convex column is in sealing connection with the inner wall of the limiting part.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] The mode does not need artificial intervention, the ink suction speed is faster, and there is no problem of ink spilling on the desktop to cause dirt, through the setting of the multi-stage limiting boss, when the ink in the ink bottle is consumed to half, the pen head cannot contact the ink liquid surface in the high position limiting state, at the moment, the pen barrel can be pressed down to the second ink suction gear of the low position of the liquid surface, so that the ink in the ink bottle can be consumed, and the pen nozzle does not contact the ink all the time, and the pen nozzle does not need to be wiped after replenishment.
