Tool holding and testing device

Abstract

A tool holding and testing device includes a plate, a tool having a rotatable barrel, and a device for rotatably securing the barrel of the tool to the plate, and for allowing the barrel to be tested and rotated relative to the plate without disengaging the tool from the plate. The barrel includes a non-circular opening for receiving a non-circular retaining member which includes one or more stops engaged with the barrel for rotatably securing the barrel of the tool to the plate and which includes a knob for rotating the retaining member relative to the plate.

I claim:

         3 . The device according to  claim 2 , wherein said opening of said barrel and said retaining member each includes a non-circular cross section.  
     
     
         4 . The device according to  claim 2 , wherein said retaining member includes a rod extended therefrom and rotatably secured to said plate.  
     
     
         5 . The device according to  claim 4 , wherein said rod includes a free end having a hook provided thereon for engaging with said plate and for securing said retaining member to said plate.  
     
     
         6 . The device according to  claim 2 , wherein said retaining member includes at least one stop extended therefrom and engaged with said barrel for rotatably securing said barrel of said tool to said plate.  
     
     
         7 . The device according to  claim 2 , wherein said retaining member includes a knob extended forward therefrom for rotating said retaining member relative to said plate.  
     
     
         8 . The device according to  claim 2 , wherein said retaining member includes at least one chamber formed therein and defined by a partition for weight reducing purposes.  
     
     
         9 . The device according to  claim 1 , wherein said plate includes a recess formed therein for receiving said tool.  
     
     
         10 . The device according to  claim 1  further comprising means for mounting said tool to said plate.  
     
     
         11 . The device according to  claim 1 , wherein said plate includes a pair of casings attached thereto and each having a channel formed therein, a frame including two panels engageable into said channels of said casings respectively, and said frame is engaged with said tool for retaining and securing said tool to said plate.  
     
     
         12 . The device according to  claim 11  further comprising means for locking said frame to said plate.  
     
     
         13 . The device according to  claim 12 , wherein said locking means includes at least one catch member provided in said plate and engageable with said frame for securing and locking said frame to said plate.  
     
     
         14 . The device according to  claim 13 , wherein said plate includes at least one orifice formed therein, said at least one catch member is extended in said at least one orifice of said plate.  
     
     
         15 . The device according to  claim 13 , wherein said frame includes at least one cavity formed therein, said at least one catch member is engaged into said at least one cavity of said frame for securing said frame to said plate.  
     
     
         16 . The device according to  claim 15 , wherein said at least one cavity of said frame is formed in one of said panels of said frame.
