<p>The drawing device includes a first driving element 14, a bolt 15, a plurality of second driving elements 20 and a plurality of clipping rods 21. The first driving element drives the second driving elements to rotate simultaneously so that the clipping rods are able to move between a first position and a second position. Each clipping rod includes a hook portion 22 (to hook a bottom of objects to be drawn out) which is able to turn freely relative to a respective second driving element so that the hook may face outward or inward. The bolt is disposed in a threaded hole 141 of the first driving element and may abut against an object to be drawn out such as a bearing (30, Figure 2).</p> |
