[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a portable steel bar binder for steel mesh, including an operating part, a rotating part, a sleeve, and a hook. The rotating part is a single twisted structure made by twisting a long steel plate around itself. The operating part is slidably sleeved and connected to the outside of the rotating part. The sleeve is fixedly connected to the bottom of the rotating part. The sleeve is provided with an internal thread, and the top of the hook is provided with an external thread. The external thread is screwed to the internal thread to detachably connect the hook and the sleeve.

[0006] Preferably, the operating member comprises a circular tube and an operating portion, the operating portion is welded to the top of the circular tube, a guide hole is provided on the operating portion, the guide hole is a rectangular through hole, and the central axis of the rectangular through hole coincides with the central axis of the circular tube.

[0007] Preferably, an extension rod is detachably connected between the sleeve and the hook via threads.

[0008] Preferably, the extension rod includes an extension steel pipe and a transition piece, the transition piece is a sleeve structure, the top of the transition piece is connected to the bottom of the extension steel pipe by threaded connection or welding, and the hook is threadedly connected to the transition piece; the top of the extension steel pipe is provided with an external thread, which is screwed to the internal thread of the sleeve.

[0009] Preferably, the external thread of the hook is the same size as the external thread of the top of the extended steel pipe.

[0010] Preferably, a baffle is welded and connected to the top of the rotating member, and the size of the baffle is larger than the size of the rectangular through hole of the operating member.

[0011] The beneficial effects of adopting the above technical solution are: 1. The components of the utility model have a simple structure and low requirements for processing and manufacturing precision. They can be manufactured on the construction site. The materials used can be steel pipes, steel plates or steel bars, which are easy to obtain. The production cost and maintenance cost are very low. It is suitable for projects with steel mesh construction such as roads, bridges, and buildings, and can be widely promoted and used.

[0012] 2. The rotating part adopts a twisted structure, and the operating part has a guide hole. Under the guidance of the guide hole, the operating part moves in a straight line along the rotating part, which can drive the rotating part to rotate, thereby driving the hook to rotate to complete the wire binding work. It is no longer necessary to manually rotate the hook for binding, which not only improves the binding efficiency, but also reduces the labor intensity of workers.

[0013] 3. An extension rod is installed between the hook and the sleeve. The extension rod is connected to the transition piece. The hook can be connected to the transition piece or the sleeve. Workers can remove the extension rod during the binding process and tie the steel bars while squatting. They can also determine the length of the extension rod according to their personal height and working habits. By connecting the extension rod, they can change the binding posture and reduce the fatigue caused by the same posture. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] like Figure 1 As shown, the portable rebar binder includes an operating member 2, a rotating member 3, a sleeve 4, and a hook 6. The rotating member 3 is a single twisted structure formed by twisting a long steel plate around itself. The operating member 2 includes a round tube and an operating part. The operating part can be a round steel plate welded to the top of the round tube. A guide hole 21 is provided on the operating part, and the guide hole is a rectangular through hole, and the central axis of the rectangular through hole coincides with the central axis of the round tube. The length of the guide hole 21 is greater than the width of the steel plate of the rotating member 3, and the width of the guide hole 21 is greater than the thickness of the steel plate of the rotating member 3. The inner diameter of the round tube used by the operating member 2 is slightly larger than the outer dimensions of the rotating member 3, so as to facilitate the relative movement of the rotating member 3 and the operating member 2. As shown Figure 2 As shown, the rotating member 3 passes through the guide hole 21. The operating member 2 can automatically fall down along the rotating member 3 under the action of gravity. When the operating member 2 moves up and down along a straight line on the rotating member 3, the guide hole 21 moves in a straight line, which will drive the rotating member 3 to rotate. A baffle 1 is welded and connected to the top of the rotating member 3. The size of the baffle 1 is larger than the size of the rectangular through hole of the operating member 2 to prevent the operating member 2 from slipping out of the rotating member 3 from the top.

[0019] In one embodiment of the connection between the rotating member 3 and the hook 6, a sleeve 4 is welded to the bottom of the rotating member 3, and the outer diameter of the sleeve 4 is larger than the inner diameter of the round tube of the operating member 2. The sleeve 4 is provided with an internal thread. The top of the hook 6 is provided with an external thread, which is screwed with the internal thread of the sleeve 4, so that the hook 3 and the sleeve 4 are detachably connected together.

[0020] Another connection embodiment of the rotating member 3 and the hook 6, an extension rod 5 is detachably connected between the sleeve 4 and the hook 6 by thread. The extension rod 5 includes an extension steel pipe and a transition piece 7, and the top of the transition piece 7 is connected to the bottom of the extension steel pipe by thread connection or welding. The top of the extension steel pipe is provided with an external thread, which is screwed with the internal thread of the sleeve 4. The transition piece 7 is a sleeve structure and is provided with an internal thread. The external thread at the top of the hook 6 is threadedly connected with the internal thread of the transition piece 7. For ease of use, the external thread of the hook 6 is the same size as the external thread at the top of the extension steel pipe of the extension rod 5. In actual use, the extension rod 5 can be removed or installed at any time.

[0021] The utility model has been tried out in the binding of road steel meshes, and the workers have given a good response.

[0022] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
