**如何正确使用与更换笔芯** 一、正确使用笔芯 1. 笔芯的安装 首先，确保笔杆内部干净无杂物。然后，将笔芯插入笔杆，直到听到“咔嚓”声或感觉到阻力为止，这表示笔芯已经安装到位。 2. 笔芯的使用 在使用时，应保持笔尖朝下，避免油墨分布不均。轻按笔尖以控制墨水流量，用力适中，避免浪费墨水或导致笔芯过早磨损。在书写时，尽量保持平稳的书写速度和力度。 二、更换笔芯 1. 准备工具 准备一支新的笔芯和一把钳子（可选）。确保新笔芯与你的笔杆兼容。 2. 拔出旧笔芯 将旧笔芯轻轻旋转几圈后拔出。有时需要适度用力，但避免过于暴力以免损坏笔杆。如果拔出有困难，可以试着用钳子夹住旧笔芯拔出。 3. 安装新笔芯

将新笔芯插入笔杆内，确保听到“咔嚓”声或感觉到阻力为止。如果发现新笔芯无法正常工作，请检查是否安装正确或与笔杆兼容。 三、注意事项 1. 避免长时间不使用后突然大量使用，这可能导致墨水供应不足或笔芯损坏。如果长时间不使用，建议取出笔芯以防其过度干燥。 2. 在保存和携带时，尽量避免长时间放置在过热或过冷的环境中，以免影响墨水性质。 3. 如果更换新笔芯后仍然无法正常书写，可能是其他部件的问题或产品自身质量问题，建议联系厂家或专业维修人员进行检查和维修。 --- **How to Use and Replace Pen Refills Correctly** **一、Correct Use of Pen Refills** 1. Installation of Pen Refills First, ensure that the inside of the pen barrel is clean and has no debris. Then, insert the pen refill into the pen barrel until you hear a "click" sound or feel resistance, indicating that the pen refill is properly installed. 2. Using the Pen Refill When using, keep the pen tip facing down to avoid uneven ink distribution. Gently press the pen tip to control the flow of ink, using a moderate force to avoid wasting ink or causing premature wear of the pen refill. Try to maintain a steady writing speed and force while writing. **二、Replacing Pen Refills** 1. Preparing Tools Prepare a new pen refill and a pair of pliers (optional). Ensure that the new pen refill is compatible with your pen barrel. 2. Removing the Old Pen Refill

Gently rotate the old pen refill a few times and pull it out. Sometimes, you may need to apply a moderate amount of force, but avoid being too violent to avoid damaging the pen barrel. If it is difficult to pull out, try using pliers to grasp the old pen refill and pull it out. 3. Installing the New Pen Refill Insert the new pen refill into the pen barrel until you hear a "click" sound or feel resistance. If you find that the new pen refill does not work properly, check if it is installed correctly or if it is compatible with the pen barrel. **三、Notes** 1. Avoid using too much at once after a long period of inactivity, which may result in insufficient ink supply or damage to the pen refill. If not using for a long time, it is recommended to take out the pen refill to prevent it from drying out too much. 2. When storing and carrying, avoid placing it in overly hot or cold environments for too long, as this may affect the nature of the ink. 3. If you still cannot write normally after replacing the new pen refill, it may be due to problems with other parts or product quality issues. It is recommended to contact the manufacturer or professional maintenance personnel for inspection and repair.
