Background

The steel bar structure needs to be woven at the initial stage of building construction, so that safer construction is facilitated, and the steel bar deviation is avoided in concrete pouring construction. However, in the prior art, manual binding by operators is generally required. In a common method, an operator holds a wire binding hook with one hand and sends a binding wire with the other hand, and the binding wire is hooked manually and rotated to wind the binding wire, so that the positions of reinforcing steel bars are fixed. In the manual operation mode, the hand holding the wire binding hook needs to repeatedly operate, the direction of the wire binding hook needs to be manually adjusted to hook the wire binding in each binding operation, and then the wire binding hook is manually twisted to rotate to complete the winding of the wire binding. The same operation action is repeated repeatedly, so that physical and psychological fatigue is easily generated, and the binding efficiency and the binding quality are reduced.

For this reason, an invention patent with publication number CN103726659B named as an electric binding hook discloses an electric binding hook improved on the basis of the existing manual binding hook. According to the electric wire binding hook, the tail part of the existing manual wire binding hook is provided with a handle for holding and a motor for driving the wire binding hook to rotate, so that the automatic winding of a binding wire is realized. And the torque limitation can be realized through the adjusting device arranged between the power motor and the wire binding rod, so that the twisting-off of the wire binding rod after excessive binding is avoided. However, in both manual binding using a wire binding hook and electric binding using the wire binding hook, the end of the wire binding hook is tightly bound to the wire at the final stage of the wire binding contraction, and is difficult to remove, thereby affecting the improvement of the work efficiency. In the case of manual binding, the problem that the binding hook cannot be removed can be solved by retracting about half a turn, but in the electric binding hook, the operation is not realized, and the operation of removing the binding hook is simplified.
