[0027] Combination Figure 1 and Figure 2 The present invention discloses a press pen according to one embodiment, including a shell 10, a pen core 20 disposed inside the shell 10, a reset member 30, and a press cap 40 sleeved on the upper end of the pen core 20 and abutting against the pen core 20. The shell 10 is sleeved on the press cap 40, and part of the press cap 40 is exposed outside the shell 10.
[0028] The outer side of the press cap 40 is provided with a press-and-retract structure, and the inner side of the outer shell 10 is provided with a press-and-retract structure. The press-and-retract structure and the press-and-retract structure work together to realize the press-and-retract of the pen refill 20.
[0029] When in use, this type of press-type pen uses the press-and-extension structure on the outside of the press cap 40 and the press-and-extension mechanism on the inside of the outer shell 10 to achieve the press-and-extension movement of the pen core 20.
[0030] Compared to traditional press-type pens, this type of press-type pen does not have a press-and-retract structure at the top of the pen core. The press-and-retract structure and the press-and-retract cooperating structure are both located on the outside of the pen core 20, which allows the length of the pen core 20 to be basically the same as the overall length of the pen, thereby increasing the ink capacity of the pen core 20.
[0031] Specifically, in this embodiment, the reset member 30 is directly connected to the pen refill 20 and the outer shell 10. In other embodiments, the reset member 30 may also be indirectly connected to the pen refill 20 and the outer shell 10 through other structures.
[0032] Specifically, in this embodiment, the pen refill 20 has a pen tip 22 for writing, and one end of the outer shell 10 is provided with a pen tip hole 101 that matches the pen tip 22. When the pen tip 22 is exposed through the pen tip hole 101, the reset member drives the pen refill 20, so that the pen tip 22 tends to retract into the pen tip hole 101.
[0033] Referring to the accompanying drawings, in this embodiment, the reset member 30 is a spring. In other embodiments, the reset member 30 may also be other elastic elements or magnetic components.
[0034] Preferred, combined Figure 3In this embodiment, the pressing and telescopic structure is a driving block 42, and the pressing and telescopic mating structure is an annular receiving groove 11. The lower side wall of the annular receiving groove 11 is provided with multiple driving teeth 12, and the upper side wall of the annular receiving groove 11 is provided with multiple protrusions 14 spaced apart from each other. The lower end of the protrusion 14 is provided with a first locking position 15 that matches the driving block 42, and a sliding channel 16 extending vertically is provided between two adjacent protrusions 14.
[0035] The drive block 42 is located in the annular receiving groove 11. When the drive block 42 is in the first locking position 15, the pressing cap 40 presses down, the drive block 42 disengages from the first locking position 15 and moves downward until it abuts against the drive teeth 12. The drive teeth 12 squeeze and drive the drive block 42 to rotate. When the pressing cap 40 rebounds, the drive block 42 moves upward along the sliding channel 16.
[0036] In other embodiments, the press-to-retract structure and the press-to-retract cooperative structure can also adopt other structures, as long as they can cooperate with each other to realize the press-to-retract of the pen refill 20.
[0037] Preferably, referring to the accompanying drawings, in this embodiment, the drive block 42 is fixedly connected to the pressing cap 40. When the drive teeth 12 press and drive the drive block 42 to rotate, the pressing cap 40 also rotates accordingly.

[0039] In other embodiments, a rotating ring may be provided on the outer side of the pressing cap 40, rotatably fitted onto the outer side of the pressing cap 40, and a driving block 42 is disposed on the rotating ring. In this case, when the driving teeth 12 compress and drive the driving block 42 to rotate, the rotating ring rotates accordingly, while the pressing cap 40 does not rotate. Preferably, in this embodiment, an annular groove is provided on the outer side of the pressing cap 40, and the rotating ring is disposed within the annular groove.
[0040] Preferably, in this embodiment, the drive block 42, the annular receiving groove 11, the drive tooth 12, the protrusion 14, the first locking position 15 and the sliding channel 16 are all located on the outside of the pen refill 20.
[0041] This structural design ensures that these structures do not occupy the length of the pen refill 20, allowing the length of the pen refill 20 to be basically the same as the overall length of the pen, thereby increasing the ink capacity of the pen refill 20.
[0042] Referring to the accompanying drawings, in a preferred embodiment, the sliding channel 16 is provided with a second locking position 13 that matches the drive block 42. In other embodiments, the second locking position 13 may not be provided.
[0043] Preferably, in this embodiment, the protrusion 14 extends downward from the upper sidewall of the annular receiving groove 11.
[0044] In other embodiments, the protrusion 14 may also be disposed in the middle region of the annular receiving groove 11, and is not connected to the lower sidewall of the annular receiving groove 11.
[0045] Preferably, in this embodiment, multiple drive teeth 12 form a ring, and multiple sliding channels 16 are formed, with multiple protrusions 14 and multiple sliding channels 16 forming a ring.
[0046] At this time, there are also multiple drive blocks 42, and the number of drive blocks 42, protrusions 14 and sliding channels 16 correspond to each other.
[0047] Preferably, in this embodiment, the surface in contact between the drive tooth 12 and the drive block 42 is an inclined plane or an inclined curved surface, and the surface in contact between the drive block 42 and the drive tooth 12 is an inclined plane or an inclined curved surface.
[0048] In other embodiments, the surfaces of the drive teeth 12 and the drive block 42 that contact each other can also be configured in other shapes. As long as the drive teeth 53 can drive the drive block 42 to rotate when the press cap 40 is pressed so that the drive teeth 12 and the drive block 42 abut against each other, it is sufficient.
[0049] Preferably, in this embodiment, both the second locking position 13 and the first locking position 15 are V-shaped grooves. The surface of the second locking position 13 that contacts the driving block 42 is an inclined plane or an inclined curved surface. The surface of the first locking position 15 that contacts the driving block 42 is an inclined plane or an inclined curved surface. The surface of the driving block 42 that contacts the first locking position 15 is an inclined plane or an inclined curved surface.
[0050] The above configuration allows the drive block 42 to slide into and out of the first locking position 15 easily. In other embodiments, it can also be configured in other shapes, as long as it does not affect the sliding of the drive block 42 into and out of the first locking position 15.
