[0040] Furthermore, first grooves 11 are provided on both sides of the upper surface of the first frame plate 1. When the movable workbench 6 moves on the first frame plate 1, the first grooves 11 can provide guidance for the movable workbench 6. The first grooves 11 are formed by two vertically arranged upright plates. The distance between the two upright plates forms the first groove 11.
