Description

Technical Field

[0001] The utility model relates to the technical field of steel bar tying wires, and more specifically to a pre-embedded steel bar tying wire device. Background Art

[0002] Rebar tying refers to the tying of steel bar structures in the early stages of construction. This process helps the steel bars better support the building structure and ensure construction safety. When tying steel bars, different tying methods and specifications will be used according to different construction locations and needs.

[0003] At present, the binding tool commonly used by construction workers is a binding hook, which usually has a rotatable handle and an inclined hook. When binding, the hook is used to hook the binding wire, and the handle is twisted to drive the hook to rotate and then the binding wire is wrapped around the steel bar. The length of the existing binding hook is mostly fixed, but in actual binding, different workers are accustomed to using binding tools of different lengths. Therefore, it is usually necessary to set binding tools of different lengths. The workers choose binding tools of different lengths according to their habits, which is very inconvenient to use, and the selection of tools requires trial to determine whether it is the length that suits their habits, which also makes tool selection more troublesome.

[0012] Technical effects and advantages of the utility model:

[0013] The utility model can pinch the knob and pull it downward to drive the two plug rods out of the sockets and unlock the knob. At the same time, sliding the knob downward will also drive the square rod to slide downward and stretch the spring. At this time, rotating the knob can drive the threaded rod to rotate through the square rod, and then drive the sliding hollow sleeve to slide upward in the through groove through the thread, thereby extending the distance between the hook body and the handle body. After the hook body is extended to a suitable position, the knob is released, and the spring will contract, pulling the square rod and the knob to reset, driving the two plug rods to re-engage into the corresponding sockets, thereby fixing the position of the hook body. Through the provided handle assembly, hook assembly, and screw assembly, the staff can extend the length of the hook assembly by simply rotating the screw assembly. The staff can adjust the length according to their needs, which can adapt to different staff and improve its convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS
