Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel bar bending, and particularly relates to a steel bar bending tool. BACKGROUND

[0002] Steel bars are basic materials commonly used in building construction, and usually, the steel bars are bundled after being bent and then used for pouring concrete. However, in the construction process, the steel bars are often not bent, or the steel bars that do not need to be bent are bent, or the bending angle is not standard. If the steel bars are disassembled, adjusted and then installed again, the construction efficiency will be greatly reduced. Therefore, in actual construction, the steel bars need to be bent without disassembling the steel bars. CONTENT OF THE UTILITY MODEL

The positioning mechanism is used for fixing the movable clamping part on the long arm rod. The fixed clamping part is sleeved on the end of the long arm rod and is parallel to the movable clamping part. When the steel bar is bent, the distance between the movable clamping part and the fixed clamping part is adjusted according to the size of the bent steel bar, the movable clamping part is fixed with the long arm rod by the positioning mechanism, the steel bar is clamped between the fixed clamping part and the movable clamping part, the long arm rod can be rotated with the center axis of the fixed clamping part as the rotation shaft, and the steel bar is bent. The installed steel bar is reformed, a large amount of reforming time is saved, the construction efficiency is improved, and the construction cost is reduced.

[0004] In some embodiments, a plurality of positioning holes with the same size and shape are formed in the long arm rod along the length direction, a fixed through hole matched with the positioning holes is formed in the movable clamping part, the fixed through hole is selectively aligned with one of the positioning holes, and the positioning mechanism comprises a positioning pin.
