Description of the figure numbers:

100 extruder die holder, 101 left catching groove limiting part, 102 right catching groove limiting part, 103 locking part, 1 half moon snap ring, 201 left stop buckle, 202 right stop buckle and 203 locking hole.

Detailed Description

For convenience of description, the center of the extrusion channel is inward toward the die holder.

First, please refer to fig. 1, which is a schematic diagram of an overall three-dimensional structure of an extruder die holder according to the present invention. An extruder die holder 100 is provided with a concave catching groove 104 extending outward from an extrusion channel thereof, a left catching groove limiting portion 101 is inwardly formed at the left bottom of the concave catching groove 104, a right catching groove limiting portion 102 is inwardly formed at the right bottom of the concave catching groove 104, wherein a plurality of locking portions 103 are formed at the bottom of the concave catching groove 104.

Please refer to fig. 4, which is a schematic diagram of the overall structure of the half-moon snap ring of the present invention. The left lower position of the half-moon snap ring 1 is provided with a convex position which is a left stop buckle 201 matched with the left buckling groove limiting part 101 of the extruder die holder 100, the right lower position of the right side of the half-moon snap ring 1 is provided with a convex position which is a right stop buckle 202 matched with the right buckling groove limiting part 102 of the extruder die holder 100, and the half-moon snap ring 1 is also provided with a plurality of locking holes 203 at positions corresponding to a plurality of locking parts 103 of the extruder die holder 100.

Referring to fig. 2, fig. 3 and fig. 5, fig. 2 is a schematic top view of an extruder die holder according to the present invention, fig. 3 is a sectional view taken along line B-B 'of fig. 2, and fig. 5 is a sectional view taken along line a-a' of fig. 4. The thickness of the half-moon snap ring 1 is the same as the height of the concave catching groove 104 of the extruder die holder 100, and the thickness of the left stopping button 201 and the right stopping button 202 of the half-moon snap ring 1 is the same as the height of the left catching groove limiting part 101 and the right catching groove limiting part 102 of the extruder die holder 100.
