Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, specifically a rebar tying device for buildings. Background Technology

[0002] Rebar tying hooks are tools used in construction for tying rebar. There are various types, each with its own advantages and disadvantages, and they are suitable for different scenarios. Common materials include stainless steel and high-hardness steel. Stainless steel hooks are not easy to rust and are suitable for humid environments; high-hardness steel hooks are resistant to hammering and are suitable for frequent use. They are suitable for small construction projects or areas with narrow spaces, and are flexible to operate, but are less efficient.

[0003] Existing rebar tying hooks require a handle to control their rotation. When the hook rotates, it rubs against the inner wall of the handle, generating resistance. Over time, this causes significant wear, increasing the gap between the handle and the hook. Furthermore, the handle weight cannot be adjusted, failing to meet the needs of different users. To address these issues, this application proposes a rebar tying device. Utility Model Content

[0004] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a rebar tying device. By adding a bearing, the tying hook can reduce rotational resistance when rotating, making rebar tying more flexible and labor-saving. The bearing can be quickly disassembled and assembled, and can be replaced in time after wear. Furthermore, the handle can be counterweighted according to usage requirements to improve comfort during use, thereby solving the problems mentioned in the background art.

[0005] (II) Technical Solution To solve the above-mentioned technical problems, this utility model provides a building steel bar binding device, including a handle sleeve and a binding hook. The binding hook is movably inserted into the inner cavity of the handle sleeve. Both ends of the inner cavity of the handle sleeve are provided with mounting grooves, and an upper bearing and a lower bearing are respectively installed in the inner cavity of the mounting grooves. The binding hook has an integrally formed first limiting ring.
