The invention provides steel bar shears with hanging buckles and a screw rod nut. The steel bar shears comprise a steel bar shear body, a screw rod, a hanging buckle grid, a hanging buckle base and a hanging device. The hanging buckle grid is formed by connecting the multiple hanging buckles. The hanging device comprises clamping plates, the nut and clamping pillars. The end of one handle arm of the steel bar shear body is connected with the two clamping plates, and the upper end of the other handle arm is provided with a hanging clip. One end of the screw rod is movably connected with the hanging buckle base, and the other end of the screw rod is provided with the nut. The hanging buckle base and the hanging buckle grid are connected together. The clamping pillars on the two opposite edges of the nut are clamped into clamping openings of the clamping plates. In the shearing process of a steel bar, a proper buckle grid of the hanging buckle grid is hung on the hanging clip, shearing plates are clamped onto the steel bar, the handle arm where the clamping plates are located is held by one hand, the other hand pulls a crank to rotate, the two handle arms are folded and accordingly the steel bar can be sheared off. When the steel bar shears are folded, the hanging buckle grid, the screw rod and the nut are taken down so that the steel bar shears can be folded, the hanging buckle grid is hung onto the hanging clip, and the screw rod and the nut are hung on the side edges of the steel bar shears. The screw rod nut is used for achieving speed change, labor is saved, and large steel bars can be sheared. By the adoption of the hanging buckle grid, shearing time can be shortened.
Description
technical field [0001] The invention belongs to the field of steel bar shears, in particular to steel bar shears equipped with hanging buckles and screw nuts. Background technique [0002] Most of the existing hand-type steel bar shears are to manually pull two handle arms of the steel bar shears to cut the steel bars. Steel bars are generally relatively hard, especially steel bars used in construction, which have quite strong hardness. Workers pull the handle arm of steel bar shears by physical strength, even if the handle arm is very long, it is also very laborious to cut steel bar. Even cutting steel bars with a diameter of eight millimeters or ten millimeters is very strenuous, and ordinary people with weak physical strength can't cut it continuously. Now there is a hydraulic shear that can easily cut commonly used steel bars. However, hydraulic shears are expensive, and they are heavy to carry when going out for construction. They also need devices such as power supp...
