AI Technical Summary
Existing stirrup bending devices are difficult to adjust the bending position according to stirrups and main bars of different diameters on the construction site, resulting in poor bending quality.
An adjustable fixed seat stirrup bending device was designed. By setting an adjustable fixed seat and a main bar positioning seat on the operating rod, a stirrup clearance groove and roller are formed to achieve flexible adjustment of the bending position and reduce friction.
This improved the quality of stirrup bending, avoiding situations where the bending position is too close or too far from the main reinforcement, thus enhancing the accuracy and efficiency of construction.

[0044] Specifically, referring to Figure 1 , Figure 2 , Figure 3 , the upper end of the operating rod 1 is an operating end for an operator to hold, the lower end of the operating rod 1 is a bending end for bending the stirrup 7, and the lower end of the operating rod 1 is connected with the fixed seat 2, wherein the installation position of the fixed seat 2 on the operating rod 1 can be adjusted. Referring to Figure 2 , the main reinforcement positioning seat 3 comprises two, the two main reinforcement positioning seats 3 are respectively arranged on the left and right sides of the operating rod 1 and are fixedly connected with the fixed seat 2, the same side of the two main reinforcement positioning seats 3 is provided with a positioning part 311, and the positioning part 311 is used for positioning cooperation with the main reinforcement 6 during the bending operation, so as to avoid separation of the main reinforcement positioning seat 3 and the main reinforcement 6 during the bending operation. Referring to Figure 2 , Figure 3 , the lower end of the operating rod 1 is located between the two main reinforcement positioning seats 3, and the stirrup avoiding groove 4 is formed between the two main reinforcement positioning seats 3 and the lower end of the operating rod 1, the stirrup avoiding groove 4 is used for placing the stirrup 7 in the stirrup avoiding groove 4 during the bending operation, so that the lower end of the operating rod 1 abuts against the stirrup 7.

Accordingly, by adjusting the length of the operating rod 1, different heights and arm lengths of the operators can be adapted, the degree to which the operators need to stretch or bend is reduced, and the comfort and efficiency of the operation are improved. After the operation is completed, the length of the operating rod 1 can also be shortened to save storage space. For environments with limited operation space, the flexibility of the operation can also be improved by adjusting the length of the operating rod 1.
