Description

Technical Field

[0001] The utility model relates to the field of carpenter pens, in particular to a carpenter pen which is easy to use. Background Art

[0002] With the continuous development of social economy and the continuous improvement of people's living standards, more and more auxiliary tools are manufactured and continuously innovated and improved. Auxiliary tools are diverse, bringing convenience to people's work and life. Carpenter pen is a relatively common auxiliary tool.

[0003] When carpenters are doing carpentry work, they will use carpenter pens to assist in the work. For example, when they need to make a piece of wood of a fixed size, they will first use the carpenter pen to draw lines on the wood raw material to mark the specific dimensions required, and then saw the wood along these lines, or use a planer to push and shave the wood to reach these lines. The assistance of the carpenter pen and the drawing of lines makes production simpler and the product size more accurate.

[0004] The current carpenter's pen generally includes a structure with a long refill, which can basically realize the line drawing function of the carpenter's pen, but its structure and function are relatively simple, and it can only realize the function of the carpenter's pen. When writing is needed, since the refill of the carpenter's pen is long, it is inconvenient to hold and difficult to write. Therefore, it is necessary to prepare another marker pen for writing. It is necessary to purchase two pens, which is costly and inconvenient for users to use, and cannot meet the existing needs. Therefore, it is necessary to study a new technical solution to improve the current carpenter's pen. Utility Model Content
