[0018] By respectively arranging sleeves and tightening screws inside the two variable distance seats, the spacing between the two variable distance seats can be adjusted to adapt to casting structures of different widths. At the same time, multiple screws are used to make the two side pressure plates fit tightly against the outer walls of the two short side templates, so that the two long side templates fit tightly against the two short side templates to prevent cement from flowing out through the gaps during cement pouring. At the same time, two supporting feet are respectively connected to the bottom of the two variable distance seats, and the height of the universal wheel is adjusted by a lifting screw at the bottom of the supporting feet to make the two fastening mechanisms more stable.
