Four pre-fixed plug tips 504 are welded at equal intervals on the bottom surface of the lifting plate 503. The four pre-fixed plug tips 504 all penetrate the bottom plug hole 8 of the casting template body 1. A slide groove 505 is provided on the top of the adjusting shaft 501. A slider 506 is slidably connected inside the slide groove 505. A handle 507 is fixedly connected to the middle of the top surface of the slider 506. The top of the handle 507 extends to the outside of the top surface of the casting template body 1. The slider 506 Two protrusions are provided on both sides of the slide 505, and the two protrusions are slidably connected in the protrusions on both sides of the slide groove 505. The distance between the top of the handle 507 and the top surface of the casting template body 1 is slightly less than the depth of the receiving groove 9; by pulling the handle 507 upward, the handle 507 is extended to the outside of the casting template body 1, and then the handle 507 is rotated to drive the slider 506 and the protrusions on both sides to rotate together, and the protrusions will drive the adjustment shaft 501 to rotate through the slide groove 505, and when the adjustment shaft 501 rotates, it will drive the lifting plate 501 through the external thread 502 at the bottom. When the lifting plate 503 is lifted and lowered in the installation cavity 7, the lifting plate 503 will drive the pre-fixed plug tip 504 at the bottom to extend out of the plug hole 8 and insert into the ground, so as to pre-fix the casting template body 1. The casting template body 1 can be kept standing without manual support, which is more convenient to use, especially when a single person is performing construction.
