Sometimes, the staff needs to process the steel bar again in the construction site to make it more suitable for the actual situation of the site; if the steel bar is bent back to the specific steel bar processing site, a lot of time will be wasted.

[0004] The present application aims to provide a portable steel bar bending tool in the construction site. UTILITY MODEL CONTENT

[0008] A fixed arm is provided with a fixed hole to enable it to be fixed on a wooden board in the construction site; a first fixed shaft and a second shaft are fixedly connected to the fixed arm;

[0009] A driving arm is rotatably connected to the second shaft, and the driving arm is fixedly provided with a bending protruding part; the first fixed shaft, the second shaft and the free end of the bending protruding part all point to the same direction.

[0010] When the steel bar is inserted between the first fixed shaft and the second shaft, rotating the driving arm can make the bending protruding part extrude the steel bar and make the steel bar be bent at the second shaft.

[0011] Further, the bending protruding part comprises a third fixed shaft and a bearing; the third fixed shaft is fixedly arranged on the driving arm, the inner ring of the bearing is sleeved on the outer side of the third fixed shaft, and the inner ring of the bearing is fixedly connected to the third fixed shaft.

[0012] Further, the driving arm is bent upward away from the free end of the second shaft relative to the fixed arm, and then horizontally extends to form a holding part, so as to increase the distance between the surface of the wooden board where the fixed arm is fixed and the holding part.

[0013] Further, when in the idle storage state, the driving arm and the fixed arm are rotated to overlap and only the second rotating shaft of the fixed arm is exposed on one side of the driving arm, so that the volume of the driving arm and the fixed arm after being folded and stored can be further reduced, and storage is facilitated.

[0014] Further, the positioning assembly comprises a fixed seat, a limiting piece and a spring.

[0015] The fixed seat is fixedly connected with the driving arm, the limiting piece is rotationally connected with the fixed seat, and the spring is fixedly connected with the limiting piece and the driving arm at two ends.

[0016] When the driving arm and the fixed arm are rotated to overlap, the elastic force of the spring can keep the limiting piece inserted into the positioning groove of the fixed arm, and the limiting piece is used to limit the relative rotation of the driving arm and the fixed arm.

[0017] The driving arm 10 and the fixed arm 20 can be relatively rotated, and the first fixed shaft 21 and the second rotating shaft 22 are arranged on the driving arm 10, and the bending protruding part 11 is fixedly arranged on the driving arm 10.

[0030] Embodiment one

[0031] As Figures 1 to 3 , the reinforcing steel bar bending tool for construction site includes a driving arm 10 and a fixed arm 20.

[0032] The fixed arm 20 is provided with a fixed hole for fixing the fixed arm 20 on the wooden board at the construction site; one end of the first fixed shaft 21 and the second rotating shaft 22 is fixedly connected with the fixed arm 20.

[0033] The driving arm 10 is rotatably connected with the second rotating shaft 22, and the driving arm 10 is fixedly provided with the bending protruding part 11; the free ends of the first fixed shaft 21, the second rotating shaft 22 and the bending protruding part 11 all point to the same direction.

[0034] Participate Figure 2 , Figure 3 When the reinforcing steel bars are inserted between the first fixed shaft 21 and the second rotating shaft 22, the driving arm 10 is rotated to enable the bending protruding part 11 to extrude the reinforcing steel bars and make the reinforcing steel bars be bent at the second rotating shaft 22.

[0035] In summary, the driving arm 10 and the fixed arm 20 can be relatively rotated, and the first fixed shaft 21 and the second rotating shaft 22 are arranged on the driving arm 10, and the driving arm 10 is fixedly provided with the bending protruding part 11; in the process of rotating the driving arm 10 with the bending protruding part 11 relative to the first fixed shaft 21 and the second rotating shaft 22, the reinforcing steel bars inserted between the first fixed shaft 21 and the second rotating shaft 22 can be bent, and the effect of bending the reinforcing steel bars can be achieved by only arranging the driving arm 10 and the fixed arm 20, and the combination of the driving arm 10 and the fixed arm 20 makes the bending tool small and portable, and the portable reinforcing steel bar bending tool is achieved.
