The adjusting pillar 506 is fixedly installed with a protrusion 505. The positioning pillar 502 is provided with an adjusting nut 504. After the templates are assembled together, the adjusting pillar 506 can be controlled to extend. After the adjusting pillar 506 is extended, the first template 1 and the second template 7 can be supported all around. The adjusting nut 504 can limit the upward movement of the adjusting pillar 506.
[0020] The second template 7 is provided with a connecting mechanism 6, which includes a positioning base 601, a positioning through hole 602, a positioning column 603, a limiting pressure piece 604 and a limiting nut 605.
