Description

Mechanical pencil capable of storing pencil lead

technical field

The utility model belongs to the technical field of school supplies, in particular to a mechanical pencil capable of storing pencil cores.

Background technique

Mechanical pencils are one of the school supplies for students, especially primary school students, and they are used more. At present, mechanical pencils also need to be equipped with pencil core boxes. The refill box and the mechanical pencil are independent entities, which are inconvenient to use. At the same time, if the refill box is not carried, the mechanical pencil cannot be used after the refill in the mechanical pencil is used up. For the convenience of use, many students will put a few more refills in the core storage tube of the mechanical pencil. When a refill is finished writing, there is no need to take the refill from the pencil lead box, which is convenient for use. However, the above-mentioned usage method has the following defects: when you use it, you will find that if you press it down, the mechanical pencil will get stuck, which will cause great damage to the automatic pencil and accelerate its breakage. At the same time, it is easy to cause breakage of the pen core, resulting in unusability and certain losses. Patent No. 200720083152.8 discloses a mechanical pencil with a refill box, including a pen body and a pen cover. The pen body is connected to the refill box. The top opening of the refill box connects. Although this patent combines the refill case with the mechanical pencil, it has a complex structure and high cost. At the same time, the refill case is arranged outside the pen body, making it uncomfortable to use. Due to the large shape and volume, the size requirements for the pencil case are also relatively high.

In the aforementioned mechanical pencil capable of storing pencil leads, the soft pad is provided with several anti-slip protrusions.

In the above-mentioned mechanical pencil that can store pencil leads, a sensor is provided on the cap of the mechanical pencil, and an alarm is installed in the pen holder of the mechanical pencil. When the sensor senses that the head is approaching, it sends a message to the alarm to sound an alarm. , the alarm and the sensor are powered by a battery, and the battery is arranged in the pen holder.

The beneficial effects of the utility model are:

1. The utility model is simple and compact in structure and easy to use. The spare refills are set in the cylindrical ring, which avoids the defect that multiple refills are placed in the storage tube at the same time in the prior art, resulting in broken refills and unusable defects. . After the refill is finished, the mechanical pencil can be used continuously by opening the pen head and taking out the spare refill in the cylindrical ring, so as to avoid the failure of the mechanical pencil due to forgetting to bring the refill box, which will cause students to be unable to take exams and do homework.

2. The utility model is equipped with a sensor to sense the position between the student's head and the mechanical pencil, which can prevent the myopia caused by the student's head being too low when writing.
