The steel bar straightening machine for reinforced concrete frame construction has a threaded rod fixedly sleeved in the inner thread of the threaded rod jacket, and the length between the steel bar length limit plate and the steel bar straightening machine body can be adjusted by rotating the threaded rod during use.

[0004] Although there are many benefits in the above scheme, there are also the following disadvantages: the two rollers are used to clamp the steel bars under the action of multiple spring elasticity, and the motor is started, and the two gears are engaged with each other, so that the two rollers move the steel bars into the inside of the steel bar straightening machine body. However, this method of clamping the steel bars by springs is relatively simple, and the effect is relatively poor when moving the steel bars. The two rollers may slip and the steel bars cannot be moved. In addition, since there are two threaded rods, personnel need to rotate the two threaded rods at the same time to adjust the steel bar length limit plate, and the operation may be troublesome, and thus an improved design of a steel bar straightening machine for reinforced concrete frame construction is proposed.
