[0023] The following is a further description with reference to the accompanying drawings and specific embodiments: Example 1

[0024] like Figure 1 and Figure 4 As shown, a tool for quickly and labor-savingly bending stirrups of structural components at construction sites includes stirrups 1 and a bending device 2, as well as an extended handle 6. The bending device 2 includes a round tube bender 3 and a handle 5. One end of the handle 5 is connected to the side of the round tube bender 3, and the handle 5 and the stirrup round tube bender 3 are connected by welding. The handle 5 can be a solid steel bar or steel pipe, with an outer diameter of generally 20 mm and a length of generally 20 cm to 30 cm. The extension handle 6 can be retractably mounted on the handle 5. By providing the extension handle 6, the longer the handle 5 is, the less effort it will take to bend it, but the convenience of operation will decrease. Therefore, construction workers can extend the handle 5 by extending the extension handle 6 according to their needs and their own usage, which is convenient and practical. The extension handle 6 is provided with a mounting tube 601, into which the handle 5 is slidably inserted. It also includes a locking bolt 602, which is threadedly mounted on the extension handle 6 and extends into the mounting tube 601 to abut against the handle 5. The locking bolt 602 is provided to facilitate locking the extension handle 6. The extension handle 6 is made of rubber, and the locking bolt 602 is made of steel. The outer surface of the extension handle 6 is provided with anti-slip grooves. The use of rubber material can reduce the weight of the extension handle 6 and make it easier for construction workers to hold it. The anti-slip grooves can prevent construction workers from slipping during construction.

[0025] like Figure 2 and Figure 3 As shown, the round tube bender 3 is a semi-annular structure. By setting the semi-annular structure, the round tube bender 3 can be conveniently buckled on the steel bar. A convex notch 301 is provided on the round tube bender 3. The round tube bender 3 is buckled on the stirrup 1 and bent through the convex notch 301. The stirrup 1 can be clamped by setting the convex notch 301, which is convenient for bending the stirrup 1. The round tube bender 3 adopts a partial opening, and the middle is cut into a "convex" shaped convex notch 301. The length of the large mouth of the "convex" shape is about 30 mm, and the length of the small mouth is about 10 mm. In addition, it also includes an abutment plate 4 The outer end surface of the circular tube bender 3 is provided with an abutment plate 4 at the position where the convex notch 301 abuts the end surface of the stirrup 1. The abutment plate 4 is provided with an abutment curved surface 401 on the end surface of the stirrup 1. The provision of the abutment plate 4 can increase the contact area between the tool and the stirrup, facilitating bending. It also includes a support rod 402. The end of the abutment plate 4 near the handle 5 is abutted with the support rod 402. The end of the support rod 402 away from the abutment plate 4 is fixedly connected to the handle 5. The provision of the support rod 402 can provide a certain degree of support for the abutment plate 4 to prevent deformation of the abutment plate 4 due to long-term use. The bending device 2 and the abutment plate 4 are both made of steel. Example 2

[0026] like Figure 1 and Figure 4 As shown, a tool for quickly and labor-savingly bending stirrups of structural components at construction sites includes stirrups 1 and a bending device 2, as well as an extended handle 6. The bending device 2 includes a round tube bender 3 and a handle 5. One end of the handle 5 is connected to the side of the round tube bender 3. The extended handle 6 is retractably mounted on the handle 5. The extended handle 6 is provided with a mounting tube 601, into which the handle 5 is slidably inserted. The extended handle 6 also includes a locking bolt 602, which is threadedly mounted on the extended handle 6 and extends into the mounting tube 601 to abut against the handle 5. The extended handle 6 is made of rubber, and the locking bolt 602 is made of steel. The outer surface of the extended handle 6 is provided with anti-slip grooves.

[0027] like Figure 2 and Figure 3As shown, the circular tube bender 3 is a semi-annular structure with a convex notch 301 formed therein. The circular tube bender 3 is gripped onto the stirrup 1 and bends the stirrup 1 through the notch 301. The circular tube bender 3 also includes an abutment plate 4. The outer end surface of the circular tube bender 3 is provided at a position corresponding to where the notch 301 abuts the end surface of the stirrup 1. The abutment plate 4 has an abutment curved surface 401 thereon. The abutment plate 4 also includes a support rod 402. The end of the abutment plate 4 proximal to the handle 5 abuts the support rod 402, while the end of the support rod 402 distal to the abutment plate 4 is fixedly connected to the handle 5. Both the bending device 2 and the abutment plate 4 are made of steel.

[0028] The working principle of the present invention is as follows: when using the device, the extended handle 6 is pulled out according to personal needs and locked by the locking bolt 602, and then the semi-circular ring structure of the round tube bender 3 is grasped and buckled on the steel bar, and then the narrowest part of the "convex" opening in the convex notch 301 is embedded in the stirrup of the main reinforcement of the reinforced concrete component. The round tube bender 3 serves as the support point and rotation axis, and a thrust can be applied to the handle 5 to bend the stirrup 1 to a suitable angle. The bending angle can be determined according to the actual situation on site, and the bending angle can be 0-180°.

[0029] In summary, the utility model provides an adjustable extension handle 6 on the handle 5, so that construction workers can freely adjust the handle length according to the needs of workers when using the device. By increasing the handle length, the force required for bending is reduced; by providing an abutment plate 4, the bending abutment surface between the round tube bender 3 and the bending point of the stirrup 1 is increased when bending the stirrup 1, so that the tool is not easy to slip when bending, thereby reducing the difficulty of bending.

[0030] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
