As the placement plate 207 moves, the second sealing sleeve 107 is fully located at one end of the plastic pipe. Since the first sealing sleeve 103 and the second sealing sleeve 107 are designed in a conical shape, under the drive of the adjustment motor 202, plastic pipes with different apertures are fully attached to the inner walls of the first sealing sleeve 103 and the second sealing sleeve 107, ensuring the tightness of their connection.
