Thus, the extension nozzle can be rotated so that it can be simply fixed at two positions, a substantially horizontal state and a substantially vertically downward state.
The said recessed part becomes an engagement receiving part, and the said projection part becomes an engaging part. You may provide these engagement receiving parts and engagement parts in reverse. In short, any structure that can engage with each other is acceptable.

In this case, it is necessary to arrange packing or the like so that the distance between the arms of the extension nozzle can be slightly displaced in the axial direction of the shaft attachment portion, but use the elasticity of the synthetic resin that is the material. Is also possible.
As described above, the present invention has been able to propose a very convenient and simple injection mechanism by using a conventional trigger type injection mechanism or a push button type injection mechanism and additionally providing an extension nozzle to these injection mechanisms. .
