The clamp 2 is hinged to the outer side of the pen body 1, and the connecting end 33 of the clamp 2 extends into the pen body 1 and abuts against the return member 6. The clamping end 7 of the clamp 2 is stretched open so that the connecting end 33 of the clamp 2 presses the return member 6 downward to reset all the refills 3. The front end of the pen body 1 is provided with a refill outlet 25 for exposing the refill 3, and the refill 3 is provided with a refill spring 26. When resetting, the refill 3 is driven to retract the pen body 1. The side of the pen body 1 is provided with a plurality of slide grooves 27 for the push member 4 to slide. The two sides of the slide groove 27 are provided with a locking sill 28 and the two sides of the push member 4 are provided with a locking protrusion 29 that cooperates with the locking sill 28 to limit the refill 3 in the writing position. The push member 4 is also provided with two unlocking parts 30, which are used to change the color or retract all the refills 3 into the pen body 1 and reset when operating the push member 4 of the unexposed refill 3; the end of the pen body 1 with the core outlet hole 25 is the pen tip end, and the end away from the core outlet hole 25 is the pen tail end. The positions of the top, bottom, top and bottom are as follows: Figure 5 shall prevail.

[0030] The multi-color writing tool of the present invention is provided with a clamp 2 and a return component 6 at the same time, and the clamp 2 and the return component 6 are arranged to offset each other, so that the pen core 3 can not only use the clamp 2 to realize the reset function, but also use the return component 6 to realize the reset function, and the reset function is more diverse; in the normal writing process, it is more appropriate to use the return component 6 to realize the reset function, because the pressing operation of the return component 6 is more convenient, and no deformation will occur during the pressing process; after using the return component 6 as the main reset function in the normal writing process, not only the reset operation is more convenient, but also the use frequency of the clamp 2 is greatly reduced, making the clamp 2 not easily damaged; and the automatic reset function of the clamp 2 when worn can prevent the pen core 3 from being damaged or contaminated by clothes.

[0031] The bottom end of the return member 6 is provided with a first abutment 8 that abuts against the push member 4. A second abutment 9 is provided in the middle of the return member 6, and a guide slope 10 is provided on the second abutment 9. The connecting end 33 of the clamp 2 is provided with a guide block 11 that extends into the pen barrel 1 and abuts against the guide slope 10. When the clamping end 7 of the clamp 2 is opened, the guide block 11 slides relative to the guide slope 10, causing the first abutment 8 to press the push member 4 downward. This arrangement utilizes a simple slope structure to convert the rotation of the clamp 2 into the downward movement of the return member 6.

[0032] The guide slope 10 is provided on the top of the second abutment portion 9 and gradually slopes upward in a direction away from the clamp 2. This arrangement facilitates the combination of the guide slope 10 and the guide block 11, so that when the clamping end 7 of the clamp 2 is opened, the guide block 11 slides upward relative to the guide slope 10 and the first abutment portion 8 presses the actuator 4 downward.

[0033] The return member 6 further includes a push cap 5 disposed on top of the return member 6. A connecting portion 12 connected to the push cap 5 is provided on the top of the return member 6. A first connecting rod 13 is provided between the middle portion of the guide ramp 10 and the connecting portion 12. The guide block 11 is provided with a guide groove 14 that slidably engages with the first connecting rod 13. The provision of the push cap 5 makes it easier to press, and the use of the first connecting rod 13 to connect the guide ramp 10 and the connecting portion 12 not only makes the structure more compact, but also, combined with the provision of the guide groove 14, allows the guide block 11 to slide on the guide ramp 10 more smoothly and its direction of movement to be well guided, thereby making the return more reliable.

[0034] A limiting step 15 is provided on one side of the guide slope 10 close to the clamp 2 to limit the guide block 11 from sliding between the limiting step 15 and the first connecting rod 13. This setting can limit the extreme movement position of the guide block 11 so that the guide block 11 will not fall off the guide slope 10.

[0035] The push cap 5 is provided with a connecting hole 16 for embedding the connecting portion 12. A snap-fit ​​structure is provided between the outer side of the connecting portion 12 and the inner side of the connecting hole 16. The return component 6 is snap-fitted to the push cap 5 via the connecting portion 12 and the connecting hole 16. In this embodiment, the connecting portion 12 is cylindrical, and the shape of the connecting hole 16 matches that of the connecting portion 12. The snap-fit ​​structure includes a first annular protrusion 31 provided on the outer side of the connecting portion 12 and a second annular protrusion 32 provided on the inner side of the connecting hole 16. When the first annular protrusion 31 on the outer side of the connecting portion 12 is snapped into the second annular protrusion 32 on the inner side of the connecting hole 16, the return component 6 is snap-fitted to the push cap 5. The connecting portion 12 in which the return component 6 is provided is embedded in the connecting hole 16 of the push cap 5, resulting in a simpler and more compact structure. The snap-fit ​​connection between the return component 6 and the push cap 5 makes assembly and disassembly more convenient.

[0036] The second connecting rod 17 is further provided. One end of the second connecting rod 17 is connected to the guide block 11, and the other end passes through the side wall of the pen holder 1 and is connected to the connecting end 33 of the clamping member 2. An elastic member 18 is provided on the second connecting rod 17. One end of the elastic member 18 abuts against the pen holder 1 and the other end abuts against the clamping member 2.

This arrangement facilitates the installation of the elastic member 18 using the second connecting rod 17, and when the clamping end 7 of the clamping member 2 is released, the elastic member 18 automatically resets the clamping member 2 and clamps the clothing.

[0037] The pen holder 1 further includes a guide seat 19 fixed in the pen barrel 1 and located above the push member 4. The guide seat 19 is provided with a guide hole 20 that slides with the first abutment 8. This arrangement can guide the downward movement of the first abutment 8, thereby making the reset action more reliable.

[0038] The penholder 1 comprises a lower rod 21, a middle rod 22, and an upper rod 23, which are connected in sequence. The refill 3 is mounted within the lower rod 21, the actuator 4 is mounted within the middle rod 22, and the return member 6 is mounted within the upper rod 23.

The hinge seat 24 and the guide seat 19 are integrally formed with the middle rod 22. The middle portion of the clamp 2 is hinged to the hinge seat 24, and the connecting end 33 of the clamp 2 extends into the upper rod 23. This arrangement simplifies the structure of the guide seat 19 and the hinge seat 24 and facilitates the installation of the clamp 2.

[0040] The working principle of the multi-color writing tool in this embodiment is as follows:

[0041] When writing, push the push piece 4 of the corresponding color refill 3. Under the guidance of the slide groove 27, the engaging protrusion 29 of the push piece 4 is limited on the engaging ridge 28, and the refill 3 extends out of the core hole 25 and is located in the writing position. When operating the push piece 4 of the unexposed refill 3, the color can be changed; when resetting is needed, the pressing cap 5 on the return component 6 can be pressed, or the push piece 4 of the unexposed refill 3 can be pressed, or the clamping end 7 of the clamp 2 can be stretched open. However, for ease of operation, the one-button reset function is generally achieved by pressing the pressing cap 5 on the return component 6. When the pressing cap 5 is pressed, the first abutment portion 8 of the return component 6 presses down the push piece 4 to reset all the refills 3. During the resetting process of the refill 3, the engaging protrusion 29 disengages from the engaging sill 28 and retracts into the pen barrel 1 under the drive of the pen core spring 26; when wearing, the clamping end 7 of the clamp 2 is stretched open, and the connecting end 33 of the clamp 2 is pressed down, thereby driving the guide block 11 to be pressed down, and the guide block 11 slides upward relative to the guide slope 10 under the guidance of the first connecting rod 13 and the guide groove 14, and at the same time, the first abutting portion 8 of the return component 6 presses the pressing member 4 to reset all the pen cores 3, release the clamping end 7 of the clamp 2, and the elastic member 18 arranged between the clamp 2 and the pen barrel 1 drives the clamp 2 to automatically reset and clamp the clothes, and the guide block 11 of the clamp 2 slides downward relative to the guide slope 10 of the return component 6 until it abuts against the limiting step 15 of the guide slope 10.
