[0032] In this embodiment, by using the setting of the docking portion 621, it is convenient to connect the glue feeding assembly 6 and the glue injection assembly 7, and it is also convenient to disassemble and replace the glue injection assembly 7.

[0033] On the basis of the above structure, the glue injection assembly 7 includes an installation rubber tube 71, a sealing washer 72, a mixing spiral 73 and a glue injection nozzle 74.
