Referring to fig. 1 and 2 together, a description will now be given of a pressing pen according to an embodiment of the present utility model.

As shown in fig. 1 and 2, the pressing pen according to the embodiment of the utility model comprises a pen holder 1, a pen point end cover 2, a pen item 3, a pen tongue 4, a pen point 5, an ink reservoir 6, a compression spring 7, a pressing mechanism 8, a pen point sealing member 9 and a pen tail sealing member 10, wherein the pen point end cover 2 is connected to the front end of the pen holder 1, and a pen point hole 11 for extending the pen point 5 is arranged at the front end of the pen point end cover 2; the pen holder 1 is provided with a pen holder 3, the pen holder 1 is provided with a pen tongue 4, the pen tongue 4 is inserted into the pen holder 3, and the front end of the pen tongue 4 extends out of the pen holder 3 and is connected with the pen point 5; the compression spring 7 is sleeved on the periphery of the pen holder 3, the rear end of the compression spring 7 abuts against the shoulder of the rear end of the pen holder 3, and the front end of the compression spring 7 abuts against the shoulder of the front end of the pen holder 1; the pressing mechanism 8 is connected to the rear end of the pen holder 1, and is propped against the rear end of the ink storage container 6, so as to switch the telescopic state of the pen point 5; the pen point sealing piece 9 is fixedly arranged on the inner side of the pen point hole 11, the pen point sealing piece 9 is provided with a closed end, the closed end is provided with a self-closing notch which can be used for repeatedly inserting the pen point 5, and the pen point sealing piece 10 is arranged in the pen holder 1 and forms a closed cavity with the pen point sealing piece 9, and the closed cavity can be used for accommodating the pen point 5. The pressing mechanism 8 is a pressing mechanism 8 for a conventional pressing pen, and will not be described herein.

According to the pressing pen disclosed by the embodiment of the utility model, when the pressing pen is used, the pressing mechanism 8 is pressed to drive the connected ink storage container 6, pen item 3 and pen point 5 to move forwards, so that the pen point 5 extends out of the pen point hole 11 from passing through the pen point sealing piece 9, and the pressing pen can be used for writing, and has a simple structure and is convenient to use; when the pen is idle, the pressing mechanism 8 is pressed again, the connected ink storage container 6, pen head 3 and pen head 5 move backwards under the action of the compression spring 7, at the moment, the pen head 5 is retracted into the pen holder 1 and is closed by the pen head sealing piece 9 in a self-closing manner, so that the pen head 5 is positioned in a closed cavity formed by the pen head sealing piece 9 and the pen tail sealing piece 10, the pen head 5 is isolated from being contacted with external air, the pressure balance inside and outside the ink storage container 6 is kept, the pen head 5 can be effectively prevented from being air-dried, and smooth ink outlet in the next use is effectively ensured.

For example, in order to solve the problem, the closed end is provided with an inward concave circular arc groove 12, and the self-closing notch is opened on the circular arc groove 12, because the internal pressure of the ink reservoir 6 is increased to cause the ink leakage to overflow in consideration of the conditions of the increase of the ambient temperature, the carrying shake and the like. Therefore, the arc groove 12 can provide certain tension, so that the pressure balance between the inside and the outside of the pen holder 3 is ensured, and the phenomenon of ink leakage and overflow caused by overhigh internal pressure in the ink storage container 6 is effectively prevented.

Illustratively, to better protect the nib 5 of the pen, the front end of the nib end cover 2 is formed with a protecting cover body 13 matching with the shape of the nib 5, and the nib hole 11 is formed on the protecting cover body 13.

For example, in order to ensure that the ink reservoir 6, the pen holder 3 and the pen point 5 which are connected with each other can only move along a straight line without rotating, a guiding protrusion 14 is arranged on the outer peripheral wall of the pen holder 3, a guiding groove 15 extending along the axial direction of the guiding protrusion 15 is arranged on the inner peripheral wall of the pen holder 1, and the guiding protrusion 14 is in sliding fit with the guiding groove 15.

The nib sealing element 9 is sandwiched between the inner end surface of the nib hole 11 and the front end surface of the barrel 1, and the nib sealing element 9 is preferably made of silica gel, rubber or soft plastic.

Illustratively, to facilitate the assembly of the nib seal 9, the nib end cap 2 is screwed with the barrel 1. When the pen point end cover 2 is screwed into the pen holder 1 for assembly, the pen point end cover 2 can gradually press the periphery of the pen point sealing piece 9 to form a reliable sealing structure.

For example, in order to facilitate the removal of the ink reservoir 6 for filling ink, the pen holder 1 is formed by connecting the front section pen holder 1 and the rear section pen holder 1 in a threaded manner.

Illustratively, the rear end of the pen holder 1 is provided with a pen clip 16.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present utility model, and these modifications and substitutions should also be considered as being within the scope of the present utility model.
