Description

Technical Field

[0001] A novel extended control device for a steel bar binding gun relates to construction machinery, in particular to a steel bar binding gun used on a construction site. Background Art

[0002] In the construction industry, many structures are cast with cement. In order to improve the strength of cement components, steel bars are often added to cement components and laid in a mesh. In order to ensure that the position of the steel bars is fixed and unchanged, the intersections of the staggered steel bars must be connected. The common method is to tie the staggered steel bars together with wire. That is to say, during construction, the steel bars must be tied according to the construction requirements before cement casting can be carried out.

[0003] In on-site construction, there are many prefabricated steel meshes that are laid horizontally. The tying workers are tying steel bars on the horizontally laid steel meshes. They have to bend over and squat to tie the steel bars at each intersection. After tying one intersection, they move forward a little bit. After tying another intersection, they move forward a little bit. Even if a handheld automatic tying gun is used to tie steel bars, it is impossible to avoid frequent bending and squatting, which are repetitive labors. After a short period of work, the tying workers will have back pain and leg pain. Long-term work in this field is likely to cause fatigue diseases such as lumbar muscle strain. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art. The present invention provides a new type of steel bar tying gun extension control device. The new type of steel bar tying gun extension control device is composed of an operating rod, a fixing device, a handle, a control switch and a connecting device. The tying gun is installed on the operating rod through the fixing device, and the switch circuit is connected to the control switch of the extended control device through the connecting device. The tying worker can use the new type of steel bar tying gun extension control device to control the steel bar tying work of the tying gun in an upright posture. The labor intensity of the tying worker can be greatly reduced.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a new type of steel bar tying gun lengthening control device, including an operating rod, a fixing device, a handle, a control switch, and a connecting device, characterized in that: the operating rod is a rigid rod, the fixing device and the handle are installed on the operating rod, the fixing device is a mechanical device that can fix the tying gun to the operating rod, the control switch is a circuit on-off switch, the connecting device is an electrical connecting device, which is composed of an electrical connector and a wire, and the connecting device connects the circuit of the new type of steel bar tying gun lengthening control device of the present invention with the circuit of the tying gun, and the tying work of the tying gun can be controlled by the control switch of the present invention; the control switch is installed on the handle, and the operator manually moves the control switch to control the tying work of the tying gun; the control switch is installed near the jaws of the tying gun, and when the control switch touches the steel bar to turn on the control switch, the tying gun starts the tying work; the operating rod can be installed with a pry hook for lifting the steel bar.

[0006] The beneficial effect of the present invention is that a novel lengthened control device for a steel bar binding gun has a simple structure and is easy to use, and can effectively reduce the labor intensity of binding workers and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
