[0083] refer to Figure 6 The forming claw 113 includes a fixing block 114 and a pressing plate, and the pressing plate is arranged on the fixing block 114.

[0084] In this embodiment, the pressing plate is used to press the first upper sealing plate 15 , the second upper sealing plate 16 , the first lower sealing plate 17 and the second lower sealing plate 18 .

[0085] In this embodiment, the pressing plate includes a first strip plate 115 and a second strip plate 116 . One end of the first strip plate 115 is connected to one end of the second strip plate 116 , and the first strip plate 115 is fixed to the fixing block 114 .

[0086] In this embodiment, there is an angle between the first strip plate 115 and the second strip plate 116. The angle between the first strip plate 115 and the second strip plate 116 is equal to the angle between the first short side 28 and the first oblique side 29, and is also equal to the angle between the second short side 31 and the second oblique side 32.

[0087] In this embodiment, when the forming claws 113 are pressed together, the first strip plate 115 is fitted with the first upper sealing plate 15, the second upper sealing plate 16, the first lower sealing plate 17 and the second lower sealing plate 18, and the second strip plate 116 is fitted with the first front oblique side plate 21, the second front oblique side plate 25, the first rear oblique side plate 22 and the second rear oblique side plate 26. The shape of the pressing plate matches the octagonal shape of the octagonal carton, so that the upper and lower sealing plates can be well fixed.

[0088] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
