The invention discloses a tracing assisting device used for trace drawing and writing and belongs to the field of stationery. The tracing assisting device is composed of a shell, a plate holder, LED lamps, a transparent plastic plate, a battery and a switch, wherein the LED lamps are installed inside the shell, the transparent plastic plate is installed over the shell, the plate holder is installed on the left side of the transparent plastic plate, and the battery and the switch are installed on the right side of the shell. The main principle of the tracing assisting device is that lamplight of the LED lamps on the tracing assisting device penetrates through the transparent plastic plate to lighten an original copy, and then lines and words on the original copy can penetrate through tracing paper to be clearly represented. In this way, thick paper or semi-transparent paper can also be used for tracing. The tracing assisting device has the advantages of being simple in structure, high in practicability, and good in use effect.
