It also can have a fixed support, a hinge hole is set, in order to be connected with fixed support in the bottom of knife rest.

Owing to taked technique scheme, thereby the utility model cuts with steel plate with existing various hands and compares, and has conveniently moving, shears brisk.Be particularly suitable for adding the advantage of section chief's material:

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.Fig. 2 is that A among Fig. 1 is to view.Fig. 3 is the schematic diagram that the utility model is connected with fixed support.

At Fig. 1.Among Fig. 2 and the embodiment shown in Figure 3, be fixed with bottom knife 2 in the bottom of arc knife rest 1, the rear end of the rear end of knife rest 1 and cutter 3 is hinged, the front end of knife rest 1 is hinged with handgrip 4, the front end of cutter 3 is anterior hinged by gusset 5 and last handgrip 4, and the rear end of knife rest 1 also is connected with a following handgrip 6.In the time will going up handgrip 4 and following handgrip 6 with two hands and close up, gusset 5 will force cutter 3 to rotate along counter-clockwise direction around the pin joint of rear end, the blade 7 of cutter 3 sinks in the cutting edge of bottom knife 2, forms shear action, and thickness is easily cut off at the plate below 1.5 millimeters.When needs cut off the plate of 1.5 to 3 millimeters thick, can increase a fixed support 8, to increase convenience firmly, at this moment, a hinge hole 9 is arranged in the bottom of knife rest 1, by this hole knife rest 1 is connected firmly with fixed support 8.Also can do a simple support, will descend the handgrip frame firmly to get final product.
