[0018] The present invention will be described below based on the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. However, it is worth noting that the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. However, for the parts that are not described in detail, those skilled in the art can also fully understand the present invention.

[0019] In addition, those skilled in the art should understand that the drawings are only provided to illustrate the purpose, features and advantages of the present invention, and the drawings are not actually drawn according to scale.

[0020] At the same time, unless the context clearly requires otherwise, the words "include", "comprises" and similar words throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0021] See also Figure 1-Figure 7 The utility model provides a technical solution: including a mouthpiece main body 1, which is installed at the front end of an extrusion device, including a mouthpiece main body 1, the mouthpiece main body 1 is conical, and a locking structure 2 is provided at the root of the mouthpiece main body 1. The locking structure 2 includes an outer ring 21 and an inner ring 22. The outer ring 21 is sleeved on the mouthpiece main body 1, and the inner ring 22 is fixedly connected to the front end of the extrusion device.

[0022] The outer ring 21 is surrounded by locking bolts 211 , and the heads of the locking bolts 211 protrude from the inner part of the outer ring 21 . The outer wall of the inner ring 22 is surrounded by limiting grooves 221 , and the heads of the locking bolts 211 can be sunk into the limiting grooves 221 .

[0023] The outer ring 21 is further provided with a manual bolt 23 , and the limiting groove 221 is provided with a countersunk hole 222 , and the head of the manual bolt 23 can be sunk into the countersunk hole 222 . The limiting groove 221 is L-shaped.

[0024] The outer ring 21 is provided with rotating holes 212 around its periphery, and a round rod can be inserted into the rotating holes 212 . The inner ring 22 is interconnected with the extrusion device through fixing holes 223 and fixing bolts.

[0025] A boss 11 is provided below the metal body 1, and the outer ring 21 is limited by the boss 11. A slot 12 is also provided on the metal body 1, and a retaining ring can be placed in the slot 12. A sealing ring 3 is provided below the metal body 1.

[0026] When using the utility model, first, the inner ring 22 needs to be installed on the existing extrusion equipment through the fixing bolts, and then the outer ring 21 needs to be put on the mouth metal body 1 and limited by the boss 11, and then the outer ring 21 and the mouth metal body 1 are buckled on the inner ring 22 as a whole, and the locking bolt 211 will be sunk into the limiting groove 221, and then the outer ring 221 is slightly rotated, and then a round rod is inserted into the rotating hole 212 for the final tightening. Since the limiting groove 221 has a certain slope in the horizontal direction, the locking bolt 221 can achieve the wedging effect during the rotation process, and finally the head of the manual bolt 23 is driven to sink into the countersunk hole 222 for the final locking. The head of the manual bolt 23 is conical and the countersunk hole 222 is also a conical hole, which also has a certain wedging effect. The overall operation is simple and fast, and the versatility is strong. The outer ring 21 can be removed and replaced with a new mouth metal body 1 for replacement, and the overall structure is simple and the cost is not high.
