[0024] The blocking mechanism includes a C-shaped seat 4, a flexible plug 5, a locking screw 6 and a cushion block 7, wherein the C-shaped seat 4 is arranged above the bottom plate 1, the flexible plug 5 is arranged in the C-shaped seat 4, the top of the flexible plug 5 extends into the injector seat 3, the locking screw 6 is threadedly mounted on the top of the C-shaped seat 4, the cushion block 7 is arranged on the top of the injector seat 3, and the bottom of the locking screw 6 is in contact with the top of the cushion block 7;

[0025] The replacement mechanism includes two fixed plates 8, a C-shaped seat 9, a bidirectional threaded rod 10, two clamps 11 and two plug blocks 12. The two fixed plates 8 are fixedly installed on one side of the C-shaped seat 4, the C-shaped seat 9 is fixed on the top of the base plate 1, and the bidirectional threaded rod 10 is rotatably installed in the C-shaped seat 9. The two clamps 11 are threadedly sleeved on the bidirectional threaded rod 10, and the sides of the two clamps 11 that are close to each other are respectively in contact with the two fixed plates 8, and the two plug blocks 12 are respectively fixedly installed on the sides of the two clamps 11 that are close to each other.

[0026] like Figure 4 As shown, the flexible plug 5 is sleeved with an O-ring 13, and the O-ring 13 is adapted to the injector seat 3;

[0027] By providing the O-ring 13 , after the flexible plug 5 is inserted into the injector seat 3 , the plugging effect on the injector seat 3 can be improved.
