[0023] like Figure 3 and Figure 4 As shown, the tooling body 1 includes an integrally formed first positioning plate 11 and a second positioning plate 12. A first positioning block 13 is movably connected to the top of the first positioning plate 11 away from the second positioning plate 12, and a second positioning block 14 is movably connected to the top of the second positioning plate 12 away from the first positioning plate 11. A mounting hole 15 is opened on the first positioning plate 11 through its thickness direction, and a positioning hole 16 is opened in the middle of the top of the first positioning plate 11. Figure 2-4 ,from Figure 2 It can be seen from the figure that the sealing head 5 is movably engaged in the mounting hole 15 .
