Abstract
A variable spacing device includes a support member, a driving member, a number of movable graspers, a limiting block, and a pushing block. The movable graspers are slidably mounted in a line on the support member. Each movable grasper grasps a workpiece. The limiting block is mounted on the support member and arranged in parallel with the pushing member. The limiting block defines first sliding grooves having a length gradually decreasing along a same direction. The pushing block defines second sliding grooves having a length gradually increasing along a same direction. Each movable grasper moves within a corresponding one of the first sliding grooves and a corresponding one of the second sliding grooves. Two sidewalls of each first sliding groove and two sidewalls of each second sliding groove resist movement of the corresponding movable grasper.
