Description

Technical Field

[0001] The utility model relates to the field of writing utensils, in particular to a novel multi-color pen. Background Art

[0002] Existing pens for writing generally have only one refill installed, which can only meet the needs of single-color writing. Therefore, when multiple pens with different writing colors are needed (such as for marking different colors), or to improve portability, pens with multiple refills of different colors of ink are used. When using such pens, the refill is usually extended by pressing a button corresponding to the refill of a specific ink color, and switching between refills is also achieved by pressing the corresponding button.

[0003] In this type of multi-refill pen, the refill is typically locked when extended by pressing a push member until it reaches its axial limit and then pressing it radially inward. This allows the push member to engage the pen barrel under the action of a spring, thereby maintaining the extended refill. Because the positional relationship between the push member and the pen barrel changes from parallel to tilted during movement to push out the refill, when switching refills, the pressed push member releases the locking state between the push member and the pen barrel corresponding to the extended refill. However, the spring forces the push member to return to its original position, causing the push member to tilt and become stuck, preventing the extended refill from being fully retracted, affecting the smoothness of refill switching.
