For example, the weight block 8 is screwed with the mounting base 1, or a fixing through hole matched with the mounting base 1 is formed in the weight block 8, and the weight block 8 is sleeved on the mounting base 1. In addition, balancing weight 8 can be a plurality of, and a plurality of balancing weights 8 can pile up each other, and a plurality of balancing weights 8 also can encircle the central line spaced setting of mount pad 1, avoid handling device's barycenter skew.
