Description
Technical Field
[0001] The utility model relates to the technical field of line marking tools, in particular to a line marking tool with a foldable rocker handle. Background Art
[0002] The scriber is a common hand tool used in construction and decoration. It is mainly used to draw straight lines on objects as a mark for subsequent processing. Its function is similar to the ink fountain used by ancient Chinese carpenters, except that it uses color powder instead of ink to leave straight lines on objects. The rotating knob of the conventional scriber crank handle is generally arranged at the end of the crank handle, perpendicular to the crank handle and fixed on the shaft of the crank handle. The knob is exposed outside the shell, which affects the storage. In order to store the handle, it is necessary to open a hole or dig a gap in the shell to make room for the crank handle. However, because the knob at the end of the crank handle is vertically arranged with the crank handle and the two cannot rotate, even if the crank handle is stored, the knob is still completely exposed, making the product too large.
