Description

Technical Field

[0001] This utility model relates to the field of building construction, and more specifically, to a multifunctional rebar tying tool. Background Technology

[0002] In fields such as construction that involve a large amount of rebar tying work, rebar tying is a fundamental and crucial process that directly relates to the stability and safety of building structures.

[0003] Currently, traditional rebar tying methods mainly rely on workers manually wrapping wire with iron hooks to secure the rebar. In terms of tool functionality, most existing rebar tying tools are relatively simple, only capable of basic "wrapping + tightening" operations. However, in actual rebar tying operations, cutting wire and measuring are indispensable steps, requiring workers to carry additional tools such as scissors and measuring tapes to complete these operations. This not only increases the number of tools and the burden of carrying them but also reduces work efficiency, as frequent switching between different tools can lead to interruptions in the work process and increase operation time. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a multi-functional rebar tying tool.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional rebar tying tool, including a handle shell, the inside of which is provided with a storage groove, an extended adjustable handle connected to the inner side of one end of the handle shell, a hook handle connected to the inner side of the other end of the handle shell, a cutting handle connected above the hook handle and inside the storage groove, a gear extending to the outside of the handle shell being provided at the top of one end of the cutting handle, a rotating handle connected to the outside of the gear, a first connecting shaft connecting the extended adjustable handle and the end of the handle shell, a second connecting shaft connected to the inner wall of the end of the handle shell, and one end of the second connecting shaft passing through the hook handle and the cutting handle and connecting to the middle of the gear.

[0006] As a further improvement to the technical solution of this utility model, the extended adjustable handle includes a first handle rod connected to a first connecting shaft, a second handle rod connected to one end of the first handle rod, a bent handle rod provided at the end of the second handle rod, and an adjustment mechanism provided between the first handle rod and the shaft hole.

[0007] As a further improvement to the technical solution of this utility model, the end of the first handle is provided with a shaft hole for the first connecting shaft to pass through, the bent handle and the second handle are in a perpendicular structure, and the connection between the bent handle and the second handle is a chamfered structure.

[0008] As a further improvement to the technical solution of this utility model, the adjusting mechanism includes an adjusting rod fixedly connected to the end of the first handle, one end of the adjusting rod being inserted into the interior of the second handle, a groove being provided on the outer wall of the end of the second handle, a locking bolt for locking the adjusting rod being connected inside the groove, and a fastening block being provided on the top of the locking bolt.

[0009] As a further improvement to the technical solution of this utility model, a shrinkage cavity is provided inside the second handle corresponding to the outside of the adjusting rod, and an internal thread hole matching the external thread structure of the locking bolt is provided at the bottom of the groove, and the internal thread hole communicates with the inside of the shrinkage cavity.

[0010] As a further improvement to the technical solution of this utility model, one end of the shear handle is provided with a rotating part for fixed connection with gears, and a shearing part is provided on the side of one end of the shear handle.

[0011] As a further improvement to the technical solution of this utility model, one end of the hook handle is provided with a connecting plate for connecting to the second connecting shaft, the interior of the connecting plate is provided with a second shaft hole matching the structure of the second connecting shaft, and the other end of the hook handle is provided with a hook body.

[0012] As a further improvement to the technical solution of this utility model, one end of the rotating handle is provided with a toothed through hole that matches the external tooth structure of the second connecting shaft.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model designs the tool as a foldable and storage structure, which can be folded and stored away when not in use to reduce space occupation. It is also equipped with an extended and adjustable handle, which can be flipped out for hand use in different environments when the handle shell is not long enough. The extended and adjustable handle itself also has a certain range of extension and retraction. When operating, rotating the lever will loosen the locking bolt. After the user adjusts the extension and retraction length of the adjustment rod, the locking bolt is tightened, which further increases the usable length.

[0015] 2. During use, the hook handle is used to wrap and tighten the wire. By rotating the handle, the gear is driven to rotate. Since the gear is fixedly connected to the shearing handle, rotating the handle can drive the shearing handle to rotate synchronously. The shearing handle itself is designed with a scissor-like structure. Together with the hook handle, the wire can be cut when the shearing handle is rotated. The shearing handle and the hook handle share a second connecting shaft, reducing redundant parts and lowering the failure rate. The shearing direction can be adjusted to adapt to different construction scenarios, reducing tool switching steps and improving binding efficiency. The gear-shaped jaw can adjust the angle of the scissors 360 degrees for easy wire cutting. Attached Figure Description
