Fixed plates 7 are symmetrically installed at both ends of the upper surface of the processing table 1, and light columns 2 are symmetrically installed at both ends between the two fixed plates 7. Four moving blocks 3 are installed in a rectangular array at the four corners of the bottom end of the moving table 4. The four moving blocks 3 are slidably installed with two light columns 2 in pairs, and a fixed plate is installed in the middle of the upper surface of the moving table 4. The fixing mechanism is composed of a fixed electric rod 15, two polished rods 16 and a pressure plate 5.

The protruding end of the fixed electric rod 15 and the lower ends of the two polished rods 16 are jointly installed with a pressure plate 5. A layer of rubber pad is installed at the bottom of the pressure plate 5. When the fixed electric rod 15 works, the pressure plate 5 is driven down to extrude the processing table 1 to fix the mobile platform 4. Anyway, the fixation of the mobile platform 4 can be released. A layer of rubber pad installed at the bottom of the pressure plate 5 can increase friction, which can better fix the mobile platform 4.

Two rectangular grooves 17 are symmetrically provided at both ends of the upper surface of the movable platform 4. A screw shaft 19 is rotatably installed in the middle of the two rectangular grooves 17, and two round rods 18 are symmetrically installed at both ends. A handwheel 8 is installed at one end of the outer side of the two screw shafts 19. There are two movable seats 11.
