The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] A simple portable stirrup bending tool, such as Figure 1 As shown, it includes a C-shaped sleeve plate 1, and a force arm rod 2 is welded to the middle position of one side of the outer wall of the C-shaped sleeve plate 1 close to the port. A clamping notch 3 runs through the middle position of the port on the C-shaped sleeve plate 1 opposite to the force arm rod 2, and the clamping notch 3 is used to fix the steel bar.

[0021] When using, Figure 2 As shown, one hand holds the stirrup and places it perpendicular to the longitudinal reinforcement of the beam or column; the other hand holds the lever arm 2, buckles the C-shaped sleeve 1 on the longitudinal reinforcement of the beam or column, and places the stirrup in the clamping notch 3. The force is applied and rotated in the direction perpendicular to the lever arm 2 to bend the stirrup or adjust the angle of the stirrup hook.

[0022] Tool making:

[0023] A round steel bar with a length of 300 mm and a diameter of 12 mm is cut as the lever arm 2.
