A fastening knob 34 is fixedly connected to one side of the fastening bolt 35, and a gasket 33 is sleeved on the side of the fastening knob 34.

[0025] Among them, a movable bottom block 38 is rotatably installed at the lower end of the two mold blocks 31, and movable rods 37 are fixedly connected on both sides of the movable bottom block 38. The limiting tube 36 and the movable rod 37 are slidably installed inside the sliding groove 25. The two ends of the movable bottom block 38 are movably sleeved on the outer surface of the limiting rod 26, and the interior of the movable bottom block 38 is threadedly connected to the outer surface of the bidirectional screw 23.

[0026] One end of the two mold blocks 31 is rotatably mounted relative to each other so that the angle between the upper ends of the two mold blocks 31 can be adjusted. In addition, when the mold block 31 is driven to move to both sides by moving the bottom block 38, the angle of the upper end of the mold block 31 will change.
