Mechanical pencil, how to change the refill?

Generally, mechanical pencil should be used with pencil lead, and pencil lead should be replaced every once in a while, otherwise the lead core will not be automatically compensated. There are two ways to replace the common mechanical pencil in the market. The steps of replacing the refill are slightly different, one is to install it from the pen tip and the other is to install it from the pen cap. After mechanical pencil has been used for a period of time, it is inevitable that it will break down, so it must be handled in time. Let's take a look at Bian Xiao. Mechanical pencil, how to change the refill?

First, change the pen cap.

1, pen cap replacement is suitable for pulsating mechanical pencil, such as our common 2B coated pen. When replacing, first pull off the outer cover and inner plug at the rear end.

2. Then you will see a round hole for putting the refill. Put the refill into 1-5 from the round hole, and be careful not to use too much, otherwise it will get stuck easily.

3. Then install the inner plug and the outer cover in turn, press the spring outer cover, and the refill will come out. Other mechanical pencil can also change the refill in this way.

Second, change the pen tip.

1, changing the nib is suitable for rotary mechanical pencil. When replacing, rotate the pen holder clockwise until it can't move, and then the lead will automatically fall off. This method must be held at the pen cap and rotated at the pen holder.

2. Turn a little counterclockwise, put the lead in, continue to turn the pen counterclockwise, and slowly screw the lead in until it is slightly exposed and very concentrated, about 2-3 mm.

3. The pen tip is facing down. At this time, the problem came. When the pen tip is facing down, the refill will automatically drop, or it will not drop, but it will drop when the hand touches it. Don't worry, this situation is normal, because the lead has not yet entered the slot. Just find a notebook, desktop and other smooth and slightly hard materials, and gently press the lead.

How to Repair Common Faults in mechanical pencil

First of all, the refill won't come out

1, first check whether the pen tube is blocked, knock it with your hand, or try taking a lead from the bottom of the pen tip.

2. unscrew the nib, put it down, push the screw back, and then screw on the nib, and you can solve it.

Second, the small copper piece of the nib falls off.

1. Small copper sheet is used to fix pencil lead. Once it falls, mechanical pencil will lose its function. In this case, it is difficult to repair. I suggest buying another one.

2, you can try to use a fine needle, you can also press hard on the table. There is a high probability that these two methods can reassemble small copper sheets.
