[0023] When the driving motor 5 starts running, the threaded rod 6 will rotate, and the moving block 7 will move horizontally backward under the limiting action of the No. 3 rectangular slot 8, and the two oblique rods 9 will start to move. At this time, under the limiting action of the No. 1 rectangular slot 2 and the No. 2 rectangular slot 3, the two connecting rods 10 drive the two clamping plates 11 to move horizontally toward each other, which will eventually achieve the effect of fixing the raw materials.

[0024] Among them, a mounting plate 12 is fixedly installed at the rear of the top of the base plate 1, and a pneumatic cylinder 13 is fixedly installed on the top of the mounting plate 12. The bottom of the pneumatic cylinder 13 passes through the mounting plate 12 and extends to the inner side of the mounting plate 12 and is fixedly connected to the upper mold 14.

[0025] When the pneumatic cylinder 13 starts to operate, the upper mold 14 will move vertically up and down.

[0026] The bottom of the base plate 1 is fixedly connected to a power motor 16 located directly behind the fixed plate 4 , the other end of the output shaft of the power motor 16 is fixedly sleeved with a rotating shaft 17 , and the other end of the rotating shaft 17 is fixedly sleeved with a rotating plate 18 .

[0027] When the power motor 16 starts to run, the rotating shaft 17 drives the rotating plate 18 to rotate.

[0028] Among them, round rods 19 are fixedly connected to both sides of the bottom of the rotating plate 18, the bottom of the round rod 19 is fixedly connected to a rectangular block 20, the outer surface of the round rod 19 is movably connected to a sleeve rod 21, and the bottom of the sleeve rod 21 is movably connected to the top of the rectangular block 20.
