[0041] The bracket 4 is used to fix the first telescopic rod 5 and the second telescopic rod 6, and each of the filling holes 2 corresponds to one of the workpieces.
[0042] The telescopic end of the second telescopic rod 6 can drive the multiple filling caps 12 to be correspondingly covered outside the multiple filling holes 2 through the second pushing frame 8, so that the liquid in the filling box 1 can be injected into the workpiece through the injection holes and the filling holes 2 provided on the filling caps 12, respectively, thereby simultaneously injecting liquid into the multiple workpieces; the telescopic end of the first telescopic rod 5 can drive the multiple filling push plates 10 to correspondingly block the injection holes on the multiple filling caps 12 through the first pushing frame 7, and can stop the injection of multiple workpieces at the same time, thereby ensuring that the amount of liquid injected into each workpiece is uniform.
[0043] In some embodiments, the bracket 4 is fixed on the filling box 1 to support and fix the first telescopic rod 5 and the second telescopic rod 6 .
[0044] In some embodiments, see Figure 4 and Figure 5 The injection mechanism also includes multiple first push rods 9 and multiple second push rods 11; one end of the first push rod 9 is connected to the first push frame 7, and the other end is connected to the filling push plate 10; one end of the second push rod 11 is connected to the second push frame 8, and the other end is connected to the filling cap 12.
