[0032] One end of the refill assembly 10 has a pen tip 101 for writing, and the shell 20 is provided with a mounting groove 22 and a pen tip hole 24 matching the pen tip 101 and located at one end of the shell 20. The pressing member 40 is movably arranged in the mounting groove 22, and the pressing member 40 contacts the refill assembly 10 through the mounting groove 22.

[0033] The pressing member 40 includes a pressing portion 42 located on the outside and a driving portion 44 located on the inside. The refill assembly 10 is provided with a driving matching portion 102 that matches the driving portion 44. When the pressing portion 42 is subjected to external pressure, it drives the driving portion 44 to move inward and causes the driving portion 44 to squeeze the driving matching portion 102, thereby causing the refill assembly 10 to move downward relative to the housing 20, and then causing the pen tip 101 to pass through the pen tip hole 24 and be exposed to the outside. At this time, the reset structure causes the refill assembly 10 to have a tendency to move upward relative to the housing 20.

[0034] When using this press pen, the user can press the pressing part 42 to make the pen tip 101 pass through the pen tip hole 24 and be exposed outside, so that writing can be achieved. When the user stops pressing the pressing part 42, the reset structure pushes the pen core assembly 10 to move upward relative to the shell 20, so that the pen tip 101 retracts, thereby achieving reset.

[0035] Compared with traditional press pens, this press pen can automatically retract the pen tip 101, thereby preventing the user from forgetting to press the pen tip again to retract it, thereby preventing the pen tip from being damaged or contaminating other objects.

[0036] In this embodiment, the reset structure is a first magnetic member 32 and a second magnetic member 34 that are disposed opposite to each other and attract each other, and at least one of the first magnetic member 32 and the second magnetic member 34 is a magnet.

[0037] When the refill assembly 10 moves downward relative to the housing 20 , the first magnetic member 32 and the second magnetic member 34 move away from each other. Under the action of the magnetic attraction, the refill assembly 10 tends to move upward relative to the housing 20 .

[0038] A first accommodating structure (not marked in the figure) is provided at the other end of the refill assembly 10, and a second accommodating structure (not marked in the figure) is provided at the other end of the housing 20. The first magnetic member 32 is arranged in the first accommodating structure, and the second magnetic member 34 is arranged in the second accommodating structure.

In other embodiments, the specific shapes of the first magnetic member 32 and the second magnetic member 34 can also be set according to actual needs.

[0043] In other embodiments, the reset structure may also be two magnets disposed opposite each other and repelling each other. When the refill assembly 10 moves downward relative to the housing 20, the two magnets come closer together, and under the action of the magnetic repulsion, the refill assembly 10 tends to move upward relative to the housing 20.

[0044] In other embodiments, the reset structure may also be an elastic member, for example, a spring sleeved on the refill assembly 10. When the refill assembly 10 moves downward relative to the housing 20, the elastic member deforms, thereby causing the refill assembly 10 to tend to move upward relative to the housing 20.

[0045] With reference to the accompanying drawings, preferably, in this embodiment, the mounting groove 22 is located in the area where the user's finger contacts the housing 20 when writing with the press pen.
