[0020] In order to better understand the purpose, structure and function of the utility model, the following further describes in detail a device for manually and quickly bending stirrups at the construction site of the utility model with reference to the drawings.

[0021] Such as Figures 1 to 4As shown in the figure, a device for quickly manually bending stirrups at a construction site includes a handle 1 and a hoop body 2. The hoop body 2 is used to clamp the main reinforcement and is a strip-shaped body with a semi-circular through groove provided longitudinally. A first groove is opened in the middle of the hoop body 2. One side of the middle of the hoop body 2 away from the first groove is fixedly connected to the handle 1. A protection mechanism is arranged above the through groove of the hoop body 2. The protection mechanism includes a strip-shaped anti-slip guard plate 4. The anti-slip guard plate 4 is arranged above the through groove of the hoop body 2. A second groove is opened in the anti-slip guard plate 4 corresponding to the position of the first groove. One end of a first connecting rod 5.1 and a second connecting rod 5.2 are respectively connected to both sides of the anti-slip guard plate 4. The other ends of the first connecting rod 5.1 and the second connecting rod 5.2 face the handle 1 and are connected to one end of a third connecting rod 5.3. Springs 6 are arranged at positions near the ends of both ends of the third connecting rod 5.3 to connect the handle 1. The middle of the third connecting rod 5.3 is connected to one end of a pressure rod 7. The other end of the pressure rod 7 penetrates through the handle 1 and extends to the outside of the handle 1.

[0022] In this embodiment, the handle 1 can be made of steel pipe or similar hard materials. The handle 1 is 30 cm long, and there is a hole 3 with a diameter of 1.2 cm at the 11 cm position of the handle 1. The hoop body 2 is a semi-circular steel pipe with a length of 11 cm and a radius of 5 cm, and there is a first groove with a length of 3 cm in the middle. The anti-slip guard plate 4 is a semi-circular steel pipe with a length of 11 cm and a radius of 5 cm, and there is a second groove with a length of 3 cm in the middle. Each of the three connecting rods is 8 cm long, the two springs 6 have a length of 2 cm, and the pressure rod 7 has a length of 8 cm and a diameter of 1 cm.

[0023] As Figure 5 and Figure 6 shown in the figure, the first connecting rod 5.1 and the second connecting rod 5.2 are connected at an angle of 60 degrees to fix the anti-slip guard plate 4. Springs 6 are respectively fixed at both ends of the third connecting rod 5.3 and are vertically connected to the first connecting rod 5.1 and the second connecting rod 5.2, so that the anti-slip guard plate 4 and the hoop body 2 are aligned to form a circle. The pressure rod 7 is inserted into the hole 3 of the handle 1, and the pressure rod 7 is fixed to the third connecting rod 5.3 to form a complete protection mechanism. The pressure rod 7 and the springs 6 can separate or close the anti-slip guard plate 4 and the hoop body 2.

[0024] The device for quickly manually bending stirrups provided by the present utility model is made by perpendicularly welding a handle 1 made of steel pipe and a hoop body 2 of a semi-circular steel pipe with a first groove, and then fixing them together with a protection mechanism. Its structure is safe and stable, and the materials used are easily obtained. Materials can be obtained locally at the construction site and fabricated on-site. The hoop body 2 serves as a fulcrum, the handle 1 is used to apply torque, and the protection mechanism can prevent slippage during operation and cause danger. It can reduce the amount of operation, save time and effort, and is convenient and practical.

[0025] In use, hold the handle 1 with the hand and press the pressing rod 7 with the thumb to separate the anti - detachment guard plate 4 from the hoop body 2 to facilitate sleeving the main reinforcement bar. Then release the pressing rod 7. Due to the force of the spring 6, the anti - detachment guard plate 4 and the hoop body 2 form a closed loop to prevent slippage during operation and cause danger. Place the stirrup at the first groove and the second groove and perpendicular to the main reinforcement bar. Manually hold the handle 1 and rotate it in the direction where the stirrup needs to be bent. According to the torque provided by the handle 1, the stirrup can be rotated to the required angle, and the bending of the stirrup can be easily achieved and attached to the main reinforcement bar. Finally, press the pressing rod 7 to separate the anti - detachment guard plate 4 from the hoop body 2, remove the stirrup bending device, and repeat the above steps to bend the stirrup around the main reinforcement bar in sequence, so as to form the required angle and shape as designed.
