A labor-saving steel bar binding hook

Abstract

The invention discloses a novel labor-saving steel bar binding hook which comprises a binding hook body and a binding hook driving device. The binding hook driving device comprises a shell body, a pressing block, a crankshaft connecting rod mechanism, a worm gear, a worm and two springs. One end of the pressing block is fixed on the shell body through a mandrel, and the other end of the pressing block is a free end which can rotate around the mandrel. A connecting rod of the crankshaft connecting rod mechanism is connected with the free end of the pressing block. A crankshaft of the crankshaft connecting rod mechanism is connected with the worm gear which is meshed with the worm. The worm is connected with the binding hook body. One end of each spring is connected with the free end of the pressing block, and the other end is connected with the shell body. The novel labor-saving steel bar binding hook has the advantages that a traditional manual rotating binding hook is replaced by pressing the pressing block, the labor intensity of construction personnel is lowered, meanwhile, the construction efficiency of steel bar binding wire binding is improved, operation is convenient and quick, through the arranged springs, the pressing block can be reset quickly, and operation is quicker and more convenient.

Description

technical field [0001] The invention relates to a construction tool, in particular to a labor-saving steel bar binding hook used for binding steel bars. Background technique [0002] The binding of steel bar often all is to adopt binding wire, and will use steel bar binding hook when binding steel bar with binding wire, thereby steel bar binding hook is widely used on construction site as a kind of special tool. Most of the existing steel bar binding hooks are composed of a handle at one end and a curved tip at the other end. Through the hook-shaped part on the tip, the binding wire is hooked, and the steel bar binding hook is rotated, and the steel bar can be bound with the binding wire. firm. In the traditional method, steel workers use lashing hooks to tie them manually, which is labor-intensive. The hand holding the tying hook repeats the same action repeatedly, and the workers are prone to fatigue, which affects efficiency. In the prior art, motor-driven binding hooks...

Problems solved by technology

In the traditional method, steel workers use lashing hooks to tie them manually, which is labor-intensive. The hand holding the tying hook repeats the same action repeatedly, and the workers are prone to fatigue, which affects efficiency.

In the prior art, motor-driven binding hooks are also used, but the binding wires are easily twisted, and the motor-driven binding hooks are not easy to control the turning angle of the binding hooks, so the binding wires are easily twisted, which affects manufacturing costs and production time.
