Step one:
First draw two circles, leaving the outer circles unconnected below.
Step 2:
Then draw a shape similar to a "T" below, and don't seal it below.
Step 3:
Then use arcs to draw the shape in the picture. Note that the lower arcs should become sharper.
Step 4:
On both sides of the arc, draw two triangles to connect them.
Step 5:
Draw a few slashes and short lines on the middle part of the anchor to serve as ropes.
Step 6:
Finally, apply a nice color and the anchor is finished.
