Description

[Detailed Description of the Invention] The present invention relates to an improvement of a knife mainly used for electrical work etc. whose handle has an electrically insulating structure.

The purpose of this invention is to simplify assembly, ensure sufficient electrical insulation, make the product non-slip and easy to grip, and reduce material and assembly costs. A foldable knife main body 4 has a base end of a blade member 2 connected to the distal end of a metal sheath part 1 with a mekugi 3, and a space 4' in which the sheath part 1 is embedded in when closed. recesses 5 and 5' to be formed, and a cutout portion 7 that forms a passage groove 6 for rotating the knife body 4 when the sheath 1 is embedded in the recesses 5 and 5'; A handle body 8 made of an elastic electric insulating material such as rubber or synthetic resin, which is connected to the back edge so as to be foldable in two, and has a handle 7' on its inner surface, and a handle body 8 made of an elastic electrically insulating material such as rubber or synthetic resin; Projecting rods 9, 9' and fitting holes 10, 10' provided on the bottom surfaces of the recesses 5, 5' and which fit into each other to prevent the sheath 1 from being pulled out in the above-mentioned embedded state, and a handle body. 8 are made of an elastic electrical insulating material such as rubber or synthetic resin, and are fitted into the recessed holes 11, 11' provided on the outer surfaces of both sides of the bar 8 to hide the protruding portions 12 to the outside of the protruding rods 9, 9'. The gist is that the cap 13 is provided.

In addition, in the illustrated embodiment, the proximal end of the blade member 2 is attached to the tip of the sheath part 1 which is constructed by folding a metal plate into two.
are connected to form a folding type knife main body 4, and a protrusion 9 formed by extending both ends of the mekugi 3 and a protrusion 9' formed by embedding a horizontal rod are provided on both outer surfaces of the sheath part 1, and separately from this. A bivalve handle 8 is made of a rubber material and is foldably connected in two at the back edge, and the above-mentioned sheath 1 is attached to the inner surfaces of both side portions 14, 14' of the handle 8 when closed. When the knife body 4 is rotated out or inserted when the sheath part 1 is embedded in the recesses 5, 5' forming the space 4' in which the knife is fitted in the embedded state, Cutting portions 7 and 7' forming passage grooves 6 and fitting holes 10 and 10' for the above-mentioned protruding rods 9 and 9 pieces are respectively provided, and the sheath part 1 is fitted into the fitting holes 10 and 10' in the space 4'. ni ram 9,
By fitting the handle 9' into the closed state, the handle 8 is attached to the sheath 11, and at the same time, the protrusions 9, 9' are attached to the outside of the handle 8 on both sides. Extrusion part 12
Recessed holes 11, 11' are provided at locations surrounding the recessed holes 11, 11', and a separately constructed rubber cap 13 is fitted into the recessed holes 11, 11' in a depressed state, and the cap 13 is inserted into the protrusion 9, 9'. The protruding part 12 is covered with a washer 15 to cover the protruding part 12 to the outside.

Since the present invention is as described above, it is necessary to simplify the above-mentioned assembly, ensure sufficient electrical insulation, make it non-slip and easy to grip, and reduce material and assembly costs. It has a significant effect that can fully achieve the following objectives.
