[0065] The lead core taking-in method of the embodiment is as follows: Embodiment

[0066] As Figure 8 and9 The magnetic attraction pen comprises a mutually retractable writing sleeve rod, a pen core 4 and a reset spring 3, the writing sleeve rod comprises a first sleeve rod 1 and a second sleeve rod 2, the first sleeve rod 1 and the second sleeve rod 2 can be displaced up and down relative to each other, but are provided with a maximum distance limit, the pen core 4 and the reset spring 3 are arranged in the writing sleeve rod, the pen core 4 has two position states of core ejection and core collection in the writing sleeve rod, and the second sleeve rod 2 comprises a second sleeve rod main body 24 and an upper core ejection part 25 which are mutually retractable and sleeved, the second sleeve rod main body 24 is used to replace the second sleeve rod 2 and is mutually retractable and sleeved with the first sleeve rod 1, the first sleeve rod 1 is provided with an extension rod 12, the second sleeve rod 2 is provided with a matching part 20, the matching part 20 is provided with a magnet 201 and a reset slope 202, and the magnet 201 and the reset slope 202 are arranged on the upper core ejection part 25.

[0067] The upper core ejection part 25 is further provided with a pen core limiting table 22.

[0068] The extension rod 12 is provided with a magnetically attractable object 121.

[0069] The extension rod 12 can be deformed.

[0070] The magnetic attraction between the magnet 201 and the magnetically attractable object 121 is greater than the elastic force of the reset spring 3.

[0071] The first sleeve rod 1 is provided with a limiting boss 11, the second sleeve rod main body 24 is provided with a movable slot 21, the limiting boss 11 is movable in the movable slot 21, and the length of the movable slot 21 is at least the length required for core ejection.

[0072] The upper core ejection part 25 is further provided with an upper core collection boss 251, and the upper core collection boss 251 is movable in the movable slot 21.

[0073] When the pen core is ejected, the distance between the front end of the second sleeve rod main body 24 and the pen tip of the pen core 4 is 30-70 mm.

[0074] The core ejection method of the embodiment is as follows:

[0075] The pen core is pulled out, the second sleeve rod main body 24 is kept stationary, the first sleeve rod is moved upwards, and when the magnet 201 and the magnetically attractable object 121 form magnetic attraction, the pen core is in the ejection state.

[0076] The pen core is pressed out, the second sleeve rod main body 24 is kept stationary, the upper core collection boss 251 is moved downwards, and when the magnet 201 and the magnetically attractable object 121 form magnetic attraction, the pen core is in the ejection state.

[0077] The core collection method of the embodiment is as follows:

[0078] 1. Lift the retractable core, keeping the second sleeve body 24 stationary, and move the first sleeve 1 upward. After the magnet 201 and the magnetically attracted object 121 disengage, continue to move the first sleeve upward, so that the magnetically attracted object 121 deflects through the reset ramp 202 and falls back by the elastic force of the reset spring 3. The second sleeve 2 and the first sleeve 1 return to their maximum limit state, and the tip of the pen refill 4 is fully retracted into the writing sleeve, which is the retractable core state.

[0079] 2. Over-limit retraction: If the writing force is too great or the second sleeve rod 2 remains stationary, the first sleeve rod is moved downwards. When the magnet 201 and the magnetically attracted object 121 disengage from the magnetic attraction, they fall back under the elastic force of the return spring 3. The second sleeve rod 2 and the first sleeve rod 1 return to the maximum limit state, and the tip of the pen refill 4 is completely retracted into the writing sleeve rod, which is the retraction state.

[0080] 3. Press down to retract the core, keeping the second sleeve body 24 stationary. Move the upper core-retracting boss 251 downwards. After the magnet 201 and the magnetically attracted object 121 disengage, continue to move the first sleeve upwards. This causes the magnetically attracted object 121 to deflect through the reset ramp 202 and fall back under the elastic force of the reset spring 3. The second sleeve 2 and the first sleeve 1 return to their maximum limit state. The tip of the pen refill 4 is fully retracted into the writing sleeve, which is the core-retracting state.

[0081] 4. Bidirectional core retraction: Keep the first sleeve rod 1 stationary and move the upper core retraction boss 251 downward, or keep the upper core retraction boss 251 stationary and move the first sleeve rod 1 upward; after the magnet 201 and the magnetically attracted object 121 disengage from the magnetic attraction, continue to move the first sleeve rod upward, so that the magnetically attracted object 121 deflects through the reset ramp 202 and falls back by the elastic force of the reset spring 3, and the second sleeve rod 2 and the first sleeve rod 1 return to the maximum limit state, and the tip of the pen refill 4 is completely retracted into the writing sleeve rod, which is the core retraction state. Example

[0082] like Figure 10 The magnetic pen shown differs from Embodiment 3 in that the mating part 20 is further provided with a high and low groove 203 and a core-out auxiliary slope 204.

[0083] The extension rod 12 has the ability to deform left and right, as well as up and down; the high and low grooves 203 can ensure that the magnetically attracted object 121 will not be interfered with by the magnet 201 when the core is being collected; and the core-exiting auxiliary slope 204 can help the magnetically attracted object 121 to re-magnetize the magnet 201 when the core needs to be removed. Example

[0084] like Figure 11 The magnetic pen shown differs from that in Embodiment 4 in that the mating part 20 is further provided with a magnetic suction ramp 205 and a reset auxiliary ramp 206.

[0085] The reset auxiliary slope 206 can help the extension rod 12 to reset, and prepare for the next core extraction.

[0086] The magnetic attraction buffer slope 205 can reduce the force required for the magnetic attraction between the magnet 201 and the magnetically attractable object 121, and improve the error tolerance.

[0087] According to the slope size and the smoothness of the magnetic attraction buffer slope 205, the friction between the magnetic attraction buffer slope 205 and the extension rod 12 or the magnetically attractable object 121 can be determined, and the interference of the spring force of the reset spring 3 and / or the writing force during writing on the magnetic attraction between the magnet 201 and the magnetically attractable object 121 can be reduced.

[0088] Therefore, the magnetic attraction between the magnet 201 and the magnetically attractable object 121 + the friction between the magnetic attraction buffer slope 205 and the extension rod 12 or the magnetically attractable object 121 > the spring force of the reset spring 3 + the writing force during writing.

[0089] Regarding the writing force during writing, it is specifically determined according to the target customer group during the actual production of the product. If it is a primary school student, we can assume that the writing force during writing is 5-10N, and if it is a middle school student or above, we can assume that the writing force during writing is 8-15N. The spring force is determined according to the actual spring parameters during production.

[0090] When the core is extracted, if the distance between the front end of the second sleeve rod body 24 and the nib of the refill 4 is 5-30mm, the writing force is directly applied to the second sleeve rod 2, and does not interfere with the magnetic attraction between the magnet 201 and the magnetically attractable object 121, so the writing force during writing does not need to be considered in the calculation; the magnetic attraction between the magnet 201 and the magnetically attractable object 121 > the spring force of the reset spring 3; if the magnetic attraction buffer slope 205 is added, the magnetic attraction between the magnet 201 and the magnetically attractable object 121 + the friction between the magnetic attraction buffer slope 205 and the extension rod 12 or the magnetically attractable object 121 > the spring force of the reset spring 3.
