Hand tool with replaceable blade

Abstract

A hand tool with replaceable blade includes two handles pivoted to each other by means of two slip joints respectively disposed to the front end of each handle; an active part extending forward from each slip joint of the handle; a slot being provided to each active part at where close to the relative inner sides of the slip joint for the installation of a blade; the blade being provided with one or a plurality of shearing sections and one or a plurality of locking holes; and a locking member being disposed to each locking hole to secure the blade.

1 . A hand tool with replaceable blade includes two handles pivoted to each other by means of two slip joints respectively disposed to the front end of each handle; an active part extending forward from each slip joint of the handle; a slot being provided to each active part at where close to the relative inner sides of the slip joint for the installation of a blade; the blade being provided with one or a plurality of shearing sections and one or a plurality of locking holes; and a locking member being disposed to each locking hole to secure the blade.  
   
   
       2 . The hand tool of  claim 1 , wherein the hand tool relates to a clamping tool to clamp a work piece.  
   
   
       3 . The hand tool of  claim 1 , wherein the hand tool relates to a shearing tool to shear a work piece.  
   
   
       4 . The hand tool of  claim 1 , wherein the blade is made in a form of a triangle for performing shearing work.  
   
   
       5 . The hand tool of  claim 1 , wherein the blade is made in a form of a diamond for performing shearing work.  
   
   
       6 . The hand tool of  claim 1 , wherein the blade is made in a form of a quadrangle for performing shearing work.  
   
   
       7 . The hand tool of  claim 1 , wherein a shearing section of each blade is made in a form of a straight line.  
   
   
       8 . The hand tool of  claim 1 , wherein a shearing section of each blade is made in a form of corrugation.  
   
   
       9 . The hand tool of  claim 1 , wherein each blade is plated with a reinforcement material to improve its resistance to tear and wear.  
   
   
       10 . The hand tool of  claim 9 , wherein the reinforcement relates to a plating liquid containing titanium composition  
   
   
       11 . The hand tool of  claim 1 , wherein one or a plurality of threaded slot is provided to each active part; an adjustment screw is provided to each threaded slot; a slide hole is provided on the base of the blade; a nut is disposed in the slide hole; any shearing section when worn out is retracted for polishing; the polished shearing section is restored into the slot; and the adjustment screw is used to secure the blade for the shearing section of each blade to perform shearing operation once again.  
   
   
       12 . The hand tool of  claim 1 , wherein on one side opposite to the slot of each active part is provided with a locking slot; a cutting member is provided to each locking slot; and the cutting member is adapted to multiple cutting sections to cut a work piece.  
   
   
       13 . The hand tool of  claim 12 , wherein each cutting section is made of diamond to cut a work piece.  
   
   
       14 . The hand tool of  claim 1 , wherein a slot is configured with its base area smaller than that of the inclined plane at the top to accommodate a blade.
