ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a box nailing machine, and especially to a box nailing machine with an adjustable nail stopper for receiving nails of different thickness.
BACKGROUND OF THE INVENTION
Referring to
FIG. 7
, a prior nail is illustrated. In that, the stop plate
91
, guide plate
93
and nail recess
92
are fixed together. The depth of the moving groove
94
is also fixed. Therefore, the box nailing machine only jets nails of fixing thickness. If nails of different thickness are to be used, the whole nail cartridge
9
must be updated, however, this is time and labor-consumed. Therefore, it is necessary to have a novel box nailing machine which may jet nails of different thickness without needing to update nail cartridge.
SUMMARY OF THE INVENTION
A box nailing machine is disclosed. In the box nailing machine, A seat has an inner space. A base is installed below the seat. A nail stopper is installed above the base in the inner space of the seat and being confined by the inner space to move up and down. A nail receiving space is positioned between the nail stopper and the base in the seat; and an adjustable stud is passed through the seat and nail stopper. Thereby as the adjustable stud is rotated, the nail stopper is driven to be moved up and down for changing a volume of the nail receiving space.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
