                    Description
  
    
      
        FIELD OF THE INVENTION
      
    
    
      
        The present invention relates to a tool box which is assembled by a first part which is composed of two boards folded in a form of an L-shaped part, and a second part part which is composed of three boards folded in a form of a U-shaped part. The two parts are assembled to be a box with an open side into which drawers are slidably received.
      
    
    
      
        BACKGROUND OF THE INVENTION
      
    
    
      
        A conventional tool box is generally includes a box-like body and a cover which is pivotally connected to the box. The box-like body and the cover are manufactured by way of blowing which employs blowing machine to blow air into plastic material in a mold so as to form the hollowed board. The blowing process is properly suitable for manufacturing tool boxes having simple structure as described above. However, tool boxes nowadays are required to include multiple layers so as to receive more tools or bits. The multiple-layer tool box needs more molds and the molds have complicated figures, this usually costs a lot.
      
    
    
      
        The present invention intends to provide a tool box which is assembled by two foldable parts and each part includes two or three boards. The boards are connected with each other by engaging projections in one board with recesses in another board.
      
    
    
      
        SUMMARY OF THE INVENTION
      
    
    
      
        In accordance with one aspect of the present invention, there is provided a tool box and comprising a first part having a first board and a second board which is pivotally connected to the first board. The first part is in a form of an L-shaped part. The second part comprises a middle board with a third board and a fourth board respectively connected to tow sides of the middle board. The second part is in a form of an L-shaped part. The first part is engaged with the second part to form a box with a front opening. A plurality of drawers are slidably received in the tool box via the front opening and are moved along rails on the insides of the third board and the fourth board.
      
    
    
      
        The primary object of the present invention is to provide a tool box that is composed of an L-shaped first part and a U-shaped second part. Each of the first part and the second part is made by way of blowing by a simple mold so that the cost for manufacturing the tool box is low.
