Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As it is shown in figure 1, this utility model includes linear moving table bracing frame 1, linear moving table 2, keyset 3, U-frame frame 4, container upper cover 5, container cavity 6, container lower cover 7, three screw thread adaptors 8, two Rule two-port valves 9, syringe 10 and three medical silicone tubes 11.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, linear moving table bracing frame 1 is vertically fixed on workbench, linear moving table 2 is arranged on linear moving table bracing frame 1 side, keyset 3 is fixed on the mobile platform of linear moving table 2, and U-frame frame 4 bottom surface is fixed on keyset 3；U-frame frame 4 is built with liquid container, and liquid container screw rod is fixed in U-frame frame 4, and liquid container is combined by container upper cover 5, container cavity 6 and container lower cover 7；Container upper cover 5 is equipped with first, second screw thread adaptor 8, first, second screw thread adaptor 8 is connected with one end of respective medical silicone tube 11 respectively, the other end of first, second medical silicone tube 11 is connected with one end of respective Rule two-port valve 9, the other end of two Rule two-port valves 9 can connect syringe 10, container lower cover 7 is equipped with the 3rd screw thread adaptor 8, and the 3rd screw thread adaptor 8 receives hydraulic pressure outfan through the 3rd medical silicone tube 11.
