Electropneumatic V-staple driving machine

An electropneumatic V-staple driving machine comprising:

• a machine stand;
• a switching device installed on an upper side of said machine stand for effecting power supply and operational mode selections therewith;
• a first pressure cylinder mechanism, having a first cylinder shaft disposed on a cylinder frame, mounted on a top surface of said machine stand for being operated to move said first cylinder shaft up and down therefrom;
• an adjusting nut screwed to a lower portion of said first cylinder shaft for making an adjustment thereith along said cylinder shaft;
• a linking-up means adjustably screwed to an upper portion of said first cylinder shaft over said adjusting nut for being moved up and down along with said first cylinder shaft;
• a pair of L-shaped percussion members with each horizontal portion fixed on top of said linking-up mechanism for being moved up and down along with the movement of said first pressure cylinder mechanism during staple driving operations;
• a double positioning seat matched with a first support frame being mounted on top of said machine stand and situated over said linking-up mechanism, and having a first and a second adjusting handles installed on a lower portion of said double positioning seat through said first support frame for making positional adjustment therewith;
• a pair of staple setting means opposingly secured on top of said double positioning seat through said first and second adjusting handles for respectively arranging a strip of V-staples therein to perform staple driving operations in conjunction with the movement of said first pressure cylinder mechanism;
• a working table, having a pair of positioning members adjustably disposed thereon through a third and a fourth adjusting handles, provided over said front and rear staple setting devices and fixed upright on top of said machine stand for holding a workpiece between said positioning dies during staple driving operations;
• a pressure feed mechanism fixedly installed on an internal wall of said working table and functionally connected between said switching device and said first pressure cylinder mechanism through an operating switch for being activated to supply pneumatic pressure therefrom;
• and
• a second cylinder mechanism installed in a second support frame mounted on a top side of said working table and electrically connected to said switching device for keeping a workpiece in position during staple driving operations;
• whereby, two V-staples symmetrically arranged in said front and rear staple setting devices can be simultaneously punched into a wooden surface of a workpiece so as to bind the coner joints thereof.
