本文目录一览⒈How to use an automatic pencil correctly and how to change the refill
1. A fully automatic pencil is like a ballpoint pen and can be written continuously without pre ssing. The refill automatically releases lead so that the refill can be Withstands writing pre ssure and is not easy to break, reducing waste.
2. Find the button of the mechanical pencil, hold it with your finger, slowly pull out the refill, take out the refill, open the lid of the refill box, and gently take out one refill. Close the lid again, place the pencil upside down on the table, hold it firmly, and slowly put the refill in slowly.
⒉Mechanical pencils always break the lead, how to pre vent it?

First of all, correct your strength and the length of the refill. The automatic refill is a very weak wooden body. If you are not careful, it is common for the refill to break. A common meal. Secondly, because of the length of the pen core, if you play with the normal pen core and make it as long as 30 minutes, the result of the pen core breaking is obvious to all. After correcting the above two problems, the problem of mechanical pencil lead breakage will no longer occur, and you will also find that one mechanical pencil has been used for a whole semester.

In fact, the refill of the mechanical pencil is made of graphite and clay mixed in a certain proportion. These two materials have very low strength after solidification and are prone to brittle fracture. The fracture situation is closely related to the stress of the lead core. When you use a mechanical pencil, you need to hold the pencil in your hand and apply a certain amount of pre ssure before the marks appear on the paper. At this time, the pen body receives force from our hands, and the force is transmitted through the pen body to the wire extending out of the pen head.

Assume that the lead has an acting force on the surface of the paper, but the surface of the paper has a reaction force of the same magnitude and opposite direction. If you master this situation, you will be a victorious general on the field. Moreover, the occurrence of automatic pen refill breakage will also be greatly reduced. But to be honest, there are a lot of black thin pens now. You can see if that kind of pen is suitable for you. Moreover, it is not easy to break, and it is durable and has a long life.

I don’t know if this answer has helped you, but for my suggestions, I hope you can take a good look at the election. After all, this is a matter related to your studies, and the answer is for reference only.

⒊How to use automatic pencils correctly
1. A fully automatic pencil is similar to a ballpoint pen and can continue writing without pre ssing. Its refill automatically releases lead, which allows the refill to withstand writing pre ssure and reduce breakage. possibilities, thereby reducing waste.
2. To replace the refill of the mechanical pencil, first find the button on the pencil and pre ss and hold to push out the refill. After slowly pulling out the refill, open the lid of the refill box, gently take out the required refill, and then close the lid again. Place the pencil upside down on the table, pre ss the button, and gently place the lead into its fixed position.
⒋Why do mechanical pencils break after just one or two days of use?
Mechanical pencils break after one or two days of use. This may be due to the following reasons:
1. Use too much force: When using an automatic pencil, if you use too much force, it will easily cause the pencil to break down. It is easy to cause the pen core to be damaged, deformed or broken. When using a mechanical pencil, you should manipulate it gently and avoid excessive force, which can extend the life of the refill.
2. The quality of the lead is poor: Some cheap mechanical pencils may come with lead of poor quality and can break or break easily. It is recommended to choose some mechanical pencils with better quality and guaranteed brand, and maintain appropriate strength when using them to avoid core breakage.
3. Other reasons: The mechanical structure of the automatic pencil is relatively complex. If used improperly, it may cause mechanical parts to malfunction, increase friction, etc., thus making the automatic pencil unable to be used normally.
If you are using a mid- to high-grade mechanical pencil, just pay attention when using it, protect the mechanical structure, and avoid improper use. If it is an ordinary mechanical pencil, it is recommended to replace it with a better quality mechanical pencil or manual pencil.
