Omnidirectional modular device for injecting e.g. cement, has bend mounted between cartridge and extension tube, where bend has edge in its upper part, against which end of tube comes to stop in order to block mounting in position

摘要

The device has an extension tube (3) and a bend (4) which are assembled on a cartridge (1). A right tube (2) is assembled on the bend, and the bend is mounted between the cartridge and the tube. The extension tube includes an edge against which an assembled part comes to stop in order to block the rotation in a precise position. The bend has an edge in its upper part, against which an end of the right tube comes to stop in order to block the mounting in the precise position.
