Abstract
A pen track has an outer shell, a transmitting group, a rotating group, and a linking group. The transmitting group is mounted in the outer shell and has a portion rotatably abutting a drawing surface. The rotating group is mounted in the outer shell and has a modeling block. The modeling block is mounted in the outer shell, is rotated with the transmitting group, and has an outer surface and a modeling segment annularly formed on the outer surface of the modeling block and having multiple curved surfaces connecting each other. The linking group is mounted in the outer shell and has a pushing protrusion pressed against the modeling segment of the modeling block to move the linking group reciprocally relative to the outer shell along the curved surfaces of the modeling segment.
Claims17
A pen track comprising:
- an outer shell;
- a transmitting group mounted in the outer shell and having a portion for rotatably abutting a drawing surface;
- a rotating group mounted in the outer shell and having
- a modeling block mounted in the outer shell, rotated with the transmitting group, and having
- an outer surface;
- and
- a modeling segment annularly formed on the outer surface of the modeling block and having multiple curved surfaces connecting each other;
- and
- a linking group mounted in the outer shell and having
- a pushing protrusion pressed against the modeling segment of the modeling block to move the linking group reciprocally relative to the outer shell along the curved surfaces of the modeling segment, and
- a refill mounted in and extending out of the outer shell and moved with the pushing protrusion for drawing lines having a contour corresponding to a contour of the curved surfaces of the modeling segment on the drawing surface.
