[0041] The present invention will now be further described with reference to the accompanying drawings. Example 1
[0042] like Figures 1 to 3 The illustrated vibrating pen includes a retractable writing sleeve, a pen refill 4, and a return spring 3. The writing sleeve includes an inner rod 1 and an outer rod 2, which can move vertically relative to each other, but are limited by a maximum distance. The pen refill 4 and the return spring 3 are placed inside the writing sleeve. The pen refill 4 has two positions within the writing sleeve: an extension position and a refill position. The pen is characterized by having an extension protrusion A or a mating protrusion B on the inner rod 1 and outer rod 2, respectively. The extension protrusion A and the mating protrusion B engage with each other during extension, maintaining a continuous extension state. When refilling is required, external force causes the extension protrusion A and the mating protrusion B to vibrate and separate, thus eliminating the extension limit formed between them and allowing the mating distance between the outer rod 2 and the inner rod 1 to reach its maximum limit, thereby achieving the refill state.
[0043] The inner rod 1 is provided with a limiting boss 11, and the outer rod 2 is provided with a movable groove 21. The limiting boss 11 moves within the movable groove 21, and the length of the movable groove 21 is at least the length of the distance required for the core to emerge. When the limiting boss 11 slides into the movable groove 21, the limiting boss 11 cannot easily leave the movable groove 21; therefore, the inner rod 1 cannot easily break free from the restriction of the outer rod 2.
[0044] The outer rod 2 is also provided with a pen refill limiting part 22, and the tail of the pen refill 4 rests against the pen refill limiting part 22.
[0045] The inner rod 1 is provided with two core-exiting bosses A.
[0046] The outer rod 2 is provided with a mating boss B, which is in the shape of a ring.
[0047] The core-exiting boss A has a deformation force.
[0048] When the pen tip is ejected, the distance between the front end of the outer rod 1 and the pen tip of the pen tip 4 is 30~70mm.
[0049] The core extraction method in this embodiment:
[0050] Pull out the core, keep the outer rod 1 stationary, and move the inner rod upward. When the core-exiting boss A and the mating boss B form a limit, the core is in the core-exit state. Example 2
[0051] like Figures 4 to 5 The illustrated vibrating pen includes a writing sleeve that can be telescopically connected to each other, a pen tip 4, and a return spring 3. The writing sleeve includes an inner rod 1 and an outer rod 2, which can move vertically relative to each other, but are limited by a maximum distance. The pen tip 4 and the return spring 3 are placed inside the writing sleeve. The pen tip 4 has two positions within the writing sleeve: a tip-out position and a tip-out position. The outer rod 2 includes a first main body 24 and an upper tip-out component 25 that are telescopically connected to each other. The inner rod 1 and the upper tip-out component 25... The pen refill is provided with a lead-out boss A or a mating boss B. The lead-out boss A and the mating boss B engage with each other during lead-out to maintain the continuous lead-out state. When the lead needs to be retracted, external force causes the lead-out boss A and the mating boss B to vibrate and separate, thereby eliminating the lead-out limit formed between the lead-out boss A and the mating boss B. The mating distance between the first body 24 and the inner rod 1 reaches the maximum limit, and the first body 24 and the upper lead-out component 25 simultaneously reach the maximum limit state, thereby realizing the lead retraction state.
[0052] The inner rod 1 is provided with a limiting boss 11, and the first main body 24 is provided with a movable groove 21. The limiting boss 11 moves within the movable groove 21, and the length of the movable groove 21 is at least the length of the distance required for the core to emerge. When the limiting boss 11 slides into the movable groove 21 from top to bottom, the limiting boss 11 cannot easily leave the movable groove 21; therefore, the inner rod 1 cannot easily detach from the restriction of the outer rod 2.
[0053] The upper lead-out component 25 is also provided with a lead-limiting part 22, and the tail of the lead 4 rests on the lead-limiting part 22.
[0054] The inner rod 1 is provided with two core-exiting bosses A.
[0055] The upper core-outlet component 25 is provided with a mating boss B, which is in the shape of a ring.
[0056] The core-exiting boss A has a deformation force.
[0057] The upper core-exiting component 25 is also provided with an upper core-receiving boss 251, and the first main body 24 is provided with an upper movable groove 241. The upper core-receiving boss 251 is movable within the upper movable groove 241, and the length of the upper movable groove 241 is at least the length of the distance required for core exit.
[0058] The inner rod 1 includes a second main body 12 and a core-changing component 13.
[0059] The upper core-receiving protrusion 251 is also provided with a pen clip 5.
[0060] When the pen tip is ejected, the distance between the front end of the outer rod 1 and the pen tip of the pen tip 4 is 30~70mm.
[0061] The core extraction method in this embodiment:
[0062] Pull out the core, keep the first main body 24 stationary, move the inner rod 1 upward, and when the core-exiting boss A and the mating boss B form a limit, it is in the core-exiting state.
[0063] Press to eject the core: Keep the first main body 24 stationary, move the upper core ejector 25 downwards, and when the core ejector boss A and the mating boss B form a limit, it is in the core ejection state.
[0064] Bidirectional core retraction: Keep the inner rod 1 stationary and move the upper core ejector 25 downward, or keep the upper core ejector 25 stationary and move the inner rod 1 upward. When the core ejector boss A and the mating boss B form a limit, it is in the core ejection state. Example 3
[0065] like Figures 6 to 7 The illustrated vibrating pen includes a retractable writing sleeve, a pen refill 4, and a return spring 3. The writing sleeve includes an inner rod 1 and an outer rod 2, which can move vertically relative to each other, but are limited by a maximum distance. The pen refill 4 and the return spring 3 are placed inside the writing sleeve. The pen refill 4 has two positions within the writing sleeve: an extension position and a refill position. The pen is characterized by having an extension protrusion A or a mating protrusion B on the inner rod 1 and outer rod 2, respectively. The extension protrusion A and the mating protrusion B engage with each other during extension, maintaining a continuous extension state. When refilling is required, external force causes the extension protrusion A and the mating protrusion B to vibrate and separate, thus eliminating the extension limit formed between them and allowing the mating distance between the outer rod 2 and the inner rod 1 to reach its maximum limit, thereby achieving the refill state.
[0066] The inner rod 1 is provided with a limiting boss 11, and the outer rod 2 is provided with a movable groove 21. The limiting boss 11 moves within the movable groove 21. The outer rod 2 is provided with three integrally formed pressing parts, each of which has a deformation force. The limiting boss 11 is provided with a core-ejection ramp 111. The pressing parts cause the limiting boss 11 to move through the core-ejection ramp 111, thereby causing the inner rod 1 to move upward. This causes the core-ejection boss A or the cooperating boss B to engage in a limiting engagement, thereby keeping the writing instrument in the core-ejection state.
[0067] When the limiting boss 11 slides into the movable groove 21, due to the restriction of the pressing part, the limiting boss 11 cannot easily leave the movable groove 21; therefore, the inner rod 1 cannot easily break free from the restriction of the outer rod 2.
[0068] During core ejection, the limiting boss 11 moves within the movable groove 21;
[0069] When the core is retracted, the middle end of the limiting protrusion 11 and the upper end of the pressing part abut against each other;
[0070] The outer rod 2 is also provided with a pen refill limiting part 22, and the tail of the pen refill 4 rests against the pen refill limiting part 22.
[0071] The inner rod 1 is provided with two core-exiting bosses A.
[0072] The outer rod 2 is provided with two mating bosses B, which are semi-circular in shape.
[0073] The core-exiting boss A has a deformation force.
[0074] The outer rod 2 is provided with three integrally formed pressing parts, each pressing part having a deformation force. The limiting boss 11 is provided with a core-exit ramp 111. The pressing part causes the limiting boss 11 to move through the core-exit ramp 111, thereby causing the inner rod 1 to move upward, which causes the core-exit boss A or the cooperating boss B to engage in a limiting engagement, thereby keeping the writing instrument in the core-exit state.
[0075] When the pen tip is ejected, the distance between the front end of the outer rod 1 and the pen tip of the pen tip 4 is 5~30mm.
[0076] The core extraction method in this embodiment:
[0077] 1. Pull out the core, keep the outer rod 1 stationary, and move the inner rod upward. When the core-exiting boss A and the mating boss B form a limit, it is in the core-exit state.
[0078] 2. Extrusion of the core: The pressing part is squeezed, and the inner rod 1 moves upward through the core extrusion ramp 111. When the core extrusion boss A and the mating boss B form a limit, the core is in the extrusion state. Example 4
[0079] like Figure 8 The vibrating core-collecting pen shown differs from Embodiment 3 in that the three pressing parts on the outer rod 2 in Embodiment 3 are independent components and do not require deformation force, rather than being integrally formed.
[0080] The core extraction method in this embodiment is the same as that in Embodiment 3. Example 5
[0081] like Figure 9The illustrated vibrating refill pen comprises a mutually retractable writing sleeve rod, a refill 4 and a reset spring 3, the writing sleeve rod comprises an inner rod 1 and an outer rod 2, the inner rod 1 and the outer rod 2 can be displaced up and down relative to each other, but are provided with a maximum distance limit, the refill 4 and the reset spring 3 are placed in the writing sleeve rod, the refill 4 has two position states of core ejection and core retraction in the writing sleeve rod, characterized in that: the inner rod 1 and the outer rod 2 are respectively provided with a core ejection boss A or a matching boss B, the core ejection boss A and the matching boss B are mutually clamped when the core is ejected, maintaining the continuous core ejection state of the refill, when the core needs to be retracted, the core ejection boss A and the matching boss B are shaken and separated by external force, so that the core ejection limit formed between the core ejection boss A and the matching boss B disappears, and the matching distance between the outer rod 2 and the inner rod 1 reaches the maximum limit, thereby realizing the core retraction state.
[0082] The inner rod 1 is provided with a limiting boss 11, the outer rod 2 is provided with a movable groove 21, and the limiting boss 11 moves in the movable groove 21; when the core is retracted, the limiting boss 11 is resisted by the movable groove 21, so that the inner rod 1 cannot easily separate from the outer rod 2.
[0083] The inner rod 1 is provided with two core ejection bosses A.
[0084] The core ejection boss A has a deformation force.
[0085] The outer rod 2 comprises an outer rod upper part 26 and an outer rod lower part 27; the outer rod upper part 26 and the outer rod lower part 27 are mutually sleeved, and the outer rod upper part 26 and the outer rod lower part 27 can rotate relative to each other, the movable groove 21 is arranged on the outer rod lower part 27, and a rotating core ejection auxiliary slope 211 is further arranged on the movable groove 21.
[0086] A refill limiting part 22 is further arranged on the outer rod upper part 26, and the tail of the refill 4 is on the refill limiting part 22.
[0087] The outer rod upper part 26 is provided with a matching boss B, and the matching boss B is in the form of a semicircular ring.

[0090] 1. Pull out the core, keep the outer rod 1 stationary, move the inner rod up, and when the core ejection boss A and the matching boss B form a limit, it is the core ejection state.
[0091] 2. Rotate the core, keep the outer rod upper part 26 stationary, rotate the outer rod lower part 27, then pass through the rotating core ejection auxiliary slope 211, make the rod move up, and when the core ejection boss A and the matching boss B form a limit, it is the core ejection state. Embodiment 6
[0092] As Figure 10 shown in a kind of vibrating core collection pen, unlike example three, in example three, the d pressing portion on outer pole 2 is provided with three, and this embodiment only has one.
[0093] The core method of this embodiment is consistent with example three. Example 7
[0094] As Figures 11 to 12 shown in a kind of vibrating core collection pen, unlike example one, when the core is discharged, the front end of the outer pole 1 is 70-150mm away from the pen nib of the core 4.
