[0002] Pencils are a type of pen used for writing and drawing sketches. They have a history of more than 400 years. There are many types of pencils for drawing sketches. They are divided into three stages of development, namely graphite, wooden pen holders, and capped pencils. In addition, they have red and white, black and white, yellow and black stripes. The pencil plate needs to be slotted during production.

[0003] For example, a device for grooving a wooden board for processing pencils with the authorization announcement number "CN212763946U" effectively solves the problem that during the use of the existing device for grooving a wooden board for processing pencils, the residual wood chips are easily accumulated inside the semicircular straight groove, which requires the staff to clean the semicircular straight groove, increasing the labor intensity of the staff and reducing the processing efficiency of the pencil. However, the height of the grooving knife of the device for grooving a wooden board for processing pencils needs to be manually adjusted and calculated by the operator, which reduces the working efficiency of the grooving device. At the same time, when the device for grooving a wooden board for processing pencils is grooving the pencil board, since the grooving knife is not fixed, the grooving knife will drive the pencil board to move during grooving, which causes the grooving effect to deteriorate, thereby reducing the working quality of the grooving device.
