- the pressure nozzle 11 of the ram 10 can be set in a unitary manner. As shown in Fig. 15a, the pressure nozzle 11 can be separated from the ram 10 during transportation. When in use, the pressure nozzle 11 can be inserted into a corresponding hole provided in the ram 10 for use.
- the above-described retractable, foldable and split type pressure nozzles 11 are designed such that the pressure nozzles are no longer subjected to torque during transportation, thereby reducing the risk of loosening of the pressure head 10 and the mouthpiece 20. Moreover, such an arrangement can also reduce the risk of breakage of the pressure nozzle 11.
