The fixed sleeve is provided with a card seat 5, and the inner side of the card seat 5 is clamped with an adapter 6, and one side of the adapter 6 is provided There is a formed extrusion head 7, and the other end of the pull rod 4 extending from the outside of the first fixed sleeve 3 is fixedly installed with a second fixed sleeve 9 sleeved on the outside of the extruder 1 through a second bolt 8. The second bolt 8 can be used to fix the second fixed sleeve 9 while facilitating its disassembly and installation. The internal thread of the second fixed sleeve 9 is connected with an adjustment mechanism 10 fixedly installed on the extruder 1. The second fixed sleeve 9 can be used to simultaneously drive the base 5 to move through the four pull rods 4, thereby ensuring that during the installation of the adapter 6, the second fixed sleeve 9 can stably press and fix the adapter 6 through the four pull rods 4, thereby ensuring the sealing of the connection between the extruder 1 and the adapter 6.

[0022] Among them, the adjustment mechanism 10 includes a screw rod 101 with a middle thread sleeve inside the second fixed sleeve 9 and one end rotatably connected to the inside of the holder 5, and a motor 102 fixedly installed on the outside of the extruder 1. The end of the screw rod 101 extending from the outside of the second fixed sleeve 9 is fixedly connected to the output shaft of the motor 102 through a sleeve 103.

[0023] Among them, a conical surface that is compatible with the extruder 1 is provided on the side of the adapter 6 away from the forming extrusion head 7. The conical surface enables the adapter 6 to be sealed through the conical surface during the process of being installed in the extruder 1 to ensure that the material inside the extruder 1 will not overflow.

[0024] Among them, a U-shaped groove compatible with the adapter 6 is provided on the inner side of the holder 5, and the adapter 6 can rotate inside the U-shaped groove. The U-shaped groove can be used to limit the adapter 6 and at the same time provide limited support for the molding extrusion head 7, thereby ensuring that during the installation and disassembly of the molding extrusion head 7, the holder 5 can always provide limited support for the molding extrusion head 7 through the adapter 6.
