Abstract

The invention discloses a ratchet type reinforcing steel bar cutter comprising a base, a tool rest fixed to the base and a blade hinged to the tool rest. A ratchet gear is connected to the base in a rotatable mode. The blade is connected with a handle. The front end of the handle is in the shape of ratchet teeth, the ratchet teeth are meshed with the ratchet gear connected to the base. The lower portion of the handle is connected with an L-shaped shifting block. The other end of the L-shaped shifting block is tightly attached to the back of the blade. The rear end of the handle is in the shape which enables people to hold the handle by hand. The cutting edge portion of the blade is zigzag. A through hole and a groove which are used for reducing the weight are formed in the tool rest. Due to the fact that the ratchet structure is applied to the ratchet type reinforcing steel bar cutter, large shearing force can be obtained just through small human power, a good reinforcing steel bar shearing effect can be achieved, and production efficiency is high.

Description

technical field [0001] The invention relates to a hand tool, in particular to a steel bar cutter for cutting steel bars. Background technique [0002] The steel bar shears in the prior art are generally composed of a knife body and a handle, and the operation is laborious, and the knife body of this structure is easily damaged due to force, which greatly reduces the service life of the product and increases the cost of use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ratchet-type steel bar shear, which can obtain a good shearing effect with only a small amount of manpower, and has high production efficiency and long service life. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a ratchet type steel bar shears, comprising a base, a knife rest fixed on the base, and a blade hinged with the knife rest, and a ratchet gear is rotatably...
