[0026] 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.

[0027] Please see Figures 1-5 The present invention provides the following technical solution:

[0028] Example 1: Includes a cylinder 1, a hook 2, a portable structure 3, a connector 301, an elastic rope 302, a binding hook 4, a connecting structure 5, a first fixing ring 501, a first rotating ring 502, a second rotating ring 503, a second fixing ring 504, a limiting structure 6, a cavity 601, a limiting rod 602, a spring 603, an annular groove 604, and a manual screw 7;

[0029] like Figure 1 and Figure 3 As shown, a portable structure 3 for carrying is installed on the outside of the cylinder 1. The portable structure 3 includes a connector 301 and an elastic rope 302. The connector 301 is fixedly installed on the upper and lower ends of the outside of the cylinder 1, and the two ends of the elastic rope 302 are installed in the connector 301 on both sides. When the staff climbs, they can hang the steel bar binding device on their arms through the elastic rope 302, which makes it easy to carry the device.

[0030] like Figures 1-5 As shown, the hook body 2 located on the outer side of the cylinder 1 is connected to a binding hook head 4 via a connecting structure 5. The connecting structure 5 includes a first fixing ring 501, a first rotating ring 502, a second rotating ring 503, and a second fixing ring 504. First, the connecting structure 5 is fitted onto the outer side of the hook body 2. Then, the binding hook head 4 is inserted into the slot at the top of the hook body 2. Next, the second fixing ring 504 is aligned with the threaded hole on the binding hook head 4 and fixed with screws. The first fixing ring 501 is aligned with the threaded hole on the hook body 2 and fixed with screws. The non-arc end of the first fixing ring 501 is fixed. A first rotating ring 502 is connected, and a second rotating ring 503 is rotatably connected to the end of the first rotating ring 502 away from the first fixed ring 501. A second fixed ring 504 is fixedly connected to the end of the second rotating ring 503 away from the first rotating ring 502. Therefore, when the hook body 2 is connected to the binding hook head 4, and the binding hook head 4 is restricted by the manual screw 7, the binding hook head 4 can rotate without being restricted by the hook body 2. When replacing the binding hook head 4, first unscrew the screws in the first fixed ring 501 and the second fixed ring 504, take out the original binding hook head 4, and repeat the above operation to install the new binding hook head 4.

[0031] Example 2: Figure 2 and Figure 5As shown, the connecting structure 5 is equipped with a limiting structure 6 that limits the rotation of the binding hook head 4. The limiting structure 6 includes a cavity 601, a limiting rod 602, a spring 603, and an annular groove 604. The annular groove 604 is formed inside the wall of the binding hook head 4. The cavity 601 is formed inside the second rotating ring 503 and the hook body 2. The limiting rod 602 is slidably connected inside the cavity 601. A handle is fixedly installed at the end of the limiting rod 602 away from the tail end. Pulling the handle in the opposite direction to the binding hook head 4 causes the tail of the limiting rod 602 to leave the annular groove 604. At this time, the binding hook head 4 can be held and rotated for easy use. After adjustment, the handle is released. The cavity 601 is equipped with a spring 603, and the spring 603 is equipped with a limiting rod 602. Due to the elasticity of the spring 603, the tail of the limiting rod 602 automatically abuts against the inner wall of the annular groove 604, thereby limiting the binding hook head 4. The rough surface of the inner wall of the annular groove 604 makes the limitation more stable.

[0032] When using this rebar tying device, first install the tying hook 4 according to the above embodiment 2, adjust the length of the hook body 2 away from the cylinder 1, fix it with the manual screw 7, and then adjust the direction of the tying hook 4 according to embodiment 3.

[0033] The above completes a series of operations for the rebar tying device with replaceable hooks. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings.
