The old blade 4 in the application refers to a cutter in the background art, and as shown in fig. 1 and 2, the old blade 4 is diamond-shaped, and the vertex corresponding to the longer diagonal line is already used, so that the vertex corresponding to the shorter diagonal line can be reused through the cutter bar in the application; the old blade 4 shown in fig. 3 and 4 is square, and the unused top and side plates can be reused by the tool bar of the present application. Of course, the old blades 4 available in the present application are not limited to the two shapes given in the present application.

As shown in fig. 1 to 4, the present utility model provides a cutter bar capable of being processed by using an old blade 4, including a cutter handle 1 and a cutter head 2, wherein the cutter handle 1 and the cutter head 2 are fixedly connected into a whole, the cutter handle 1 is used for holding, the top surface of the cutter head 2 is provided with a concave notch along one vertex thereof, the shape of the notch matches with that of the old blade 4, after the old blade 4 is placed in the notch, the side to be used of the old blade 4 is arranged outwards, and the top surface of the cutter head 2 is also provided with a fixing piece 3 for fixing the old blade 4 in the notch.

In the above technical scheme, the operator can process by fully using the unused points or edges of the old blade 4 by holding the cutter bar by the cutter bar 1, and can make full use of the different sides of the old blade 4 to the outside according to the installation orientation of the old blade 4. After the old blade 4 is placed in the notch, the old blade is fixed by the fixing piece 3 and then can be used. Figures 1 and 2 and figures 3 and 4 are schematic illustrations of the installation of two differently shaped old blades 4, respectively.

In another technical scheme, a cutter pad 5 with the same shape as the old blade 4 is further arranged in the notch, and the old blade 4 is arranged right above the cutter pad 5 and coincides with the orthographic projection of the cutter pad 5. The cutter pad 5 is detachably connected with the cutter head 2 through a bolt 8.

In the above technical scheme, the cutter pad 5 is arranged at the lowest part of the old blade 4, and is not in direct contact with the cutter head 2, and the cutter pad 5 plays a role in buffering and compression resistance of the old blade 4. In the using process of the old blade 4, the cutter head 2 bears the stress of the old blade 4, and if the old blade 4 breaks or stretches, the whole guide rod structure can not be damaged, and only the cutter pad 5 needs to be replaced. The center of the cutter pad 5 is provided with a bolt 8 hole, and the cutter pad is fixed on the cutter head 2 through the bolt 8.

In another technical scheme, a positioning column 6 is arranged at one end of the fixing piece 3, the top surface of the old blade 4 is provided with a concave hole which is concave, and the positioning column 6 is just matched in the concave hole to fix the old blade 4. The positioning column 6 is matched in a concave hole formed in the center of the top surface of the old blade 4, so that the old blade 4 is stably fixed.

In another technical scheme, after the old blade 4 is installed, the top surface of the old blade is flush with the top surface of the cutter head 2, so that the height of the positioning column 6 can be reduced maximally, and the material consumption is reduced.

In another technical scheme, the other end of the fixing piece 3 is provided with a limiting piece 7, the limiting piece and the bottom surface of the fixing piece 3 form an obtuse angle, the other side of the cutter head 2, which is opposite to the notch, is provided with a concave inclined surface, and when the fixing piece 3 fixes the old cutter blade 4, the limiting piece 7 is just matched with the inclined surface on the cutter head 2. When the positioning column 6 is matched in the concave hole of the old blade 4 downwards, the limiting piece 7 is also matched to move downwards along the inclined plane on the cutter head 2, so that the fixing piece 3 is further firm in fixing the old blade 4.

In another embodiment, the fixing member 3 is connected to the cutter head 2 by a bolt 8 to fix the old blade 4. As shown in fig. 1 and 2, the bolt 8 is inserted into the fixing member 3 from above and fixed to the cutter head 2, and as shown in fig. 3 and 4, the bolt 8 is inserted into the fixing member 3 from below to achieve fixation. The same is true for the bolt fixation of the insert 5 and the insert 2, as shown in fig. 1 and 2, in which the bolt is inserted from above into the insert to fix the insert, as shown in fig. 3 and 4, and in which the bolt is inserted from below into the insert to fix the insert.
