[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 As shown, this utility model provides a technical solution: a pre-embedded rebar straightening device, including an annular base 1 composed of a first half-ring 101 and a second half-ring 102. The adjacent ends of the first half-ring 101 and the second half-ring 102 are rotatably connected by a pin structure, and the other ends of the first half-ring 101 and the second half-ring 102 are snapped together by a pin structure. The annular base 1 is composed of two half-rings, which makes it convenient to place the device at the position of the pre-embedded rebar during use. A hydraulic cylinder 2 is fixedly connected to one side of the first half-ring 101 and the second half-ring 102. A telescopic adjustable rod 3 is fixedly connected to the output end of the hydraulic cylinder 2, and a straightening head 4 is fixedly connected to one end of the telescopic adjustable rod 3.

[0027] The telescopic adjustable rod 3 in this application includes a fixed cylinder 301 fixedly connected to the output end of the hydraulic cylinder 2. A threaded hole for installing a limit bolt 303 is provided on one side of the fixed cylinder 301. A movable telescopic rod 302 is inserted into the fixed cylinder 301, and a limit bolt 303 is threadedly connected to one side of the fixed cylinder 301. A spring 304 is fixedly connected to one end of the telescopic rod 302, and the other end of the spring 304 abuts against the inside of the fixed cylinder 301. A scale 305 is also provided on the telescopic rod 302. The length of the telescopic adjustable rod 3 in this device is adjustable. With the use of the straightening head 4, it can adapt to steel bars of different diameters within a certain range, thereby effectively improving the use effect of the device and enhancing its practicality.

[0028] Please refer to the following carefully. Figure 1 , Figure 2 and Figure 4 The first semi-ring 101 and the second semi-ring 102 are also fixedly connected to a semi-circular auxiliary support 104 by a connecting rod 103. The two semi-circular auxiliary supports 104 can form a complete circle.

[0029] Please refer to the following carefully.Figure 1 and Figure 2 The pin structure includes a through hole 5 opened on the first half ring 101 and the second half ring 102, and a pin 6 is provided inside the through hole 5. The plug structure includes a second through hole 7 opened on the first half ring 101 and the second half ring 102, and a pluggable plug 8 is inserted into the second through hole 7.

[0030] Working principle: When using, first remove the pin 8, then open the two semi-rings to easily and quickly place the device at the position of the rebar that needs to be straightened, ensuring that the two straightening heads 4 clamp the rebar 9. The extension length of the two telescopic rods 302 can be adjusted by observing the scale 305 on the telescopic rod 302 to ensure that the extension lengths of the two telescopic rods 302 are the same. This setting makes the position of the rebar more accurately located at the center of the two semi-rings, resulting in a better straightening effect. After the position of the telescopic rods 302 is determined, it is fixed by the limit bolt 303. At this time, the hydraulic cylinder 2 is started to straighten the rebar (it is worth noting that the two hydraulic cylinders 2 work synchronously during this process). While the hydraulic cylinder 2 is working, it is best for the operator to step on the ring base 1 with their foot to avoid positional displacement that may affect the straightening accuracy.
