[0025] One side of the positioning frame 10 is inserted into the inner edge of the base frame 1 and the top frame 2 and moves along the edge. The inner side of the base frame 1 and the top frame 2 is composed of the inner I-beam of the side beam 6 to form a slide groove for the positioning frame 10 to be inserted and slide. Adjustment holes 12 are symmetrically opened on the inner edges of the base frame 1 and the top frame 2 at equal distances, and fixing holes 13 are symmetrically opened on the sides of the positioning frame 10.
