Abstract:
     The water pipe is protected from shock of falling pieces by a pair of vertical plates which is connected to the case of water-jet. The pipe of water-jet can move freely between two plates which prevent from shock of any pieces falling to the water-jet. The support of water-jet is connected to the case by flexible joining part. When a vertical force acts on the case the case sink on the bottom plate and transmits that force to the bottom plate, while the support of the water-jet does not suffer from any action of the force.
