Background technology
In life, increasing crowd, for following the fashion or curiosity for the moment, wears the objects such as various " rings ", " finger ring ", " iron ring ", " steel ring ".Through for a long time not getting along with the increase at age, the increase of physique, be instantly just difficult to take off, cause pointing the position of tying tight and break, hyperemia, swelling, fester, bring misery to people, also can there is the organs such as people's finger by metal, the situation that plastic stool material blocks, in this case, conventionally the fireman that seeks help processes, and at present, process the situation that this human body parts organ is blocked by implements, all adopt tool scissors, side-cutting pliers, the hand-operated tools such as hand saws, because this instrument is difficult to control dynamics, be difficult to control scope of damage, when can causing seeking help person to take off ring or liberation quilt card organ, suffer larger secondary injury, also use and resolve electric scissors, hydraulic shear cutting nipper, the equipments such as electric wheel, but the masses that generally seek help to fire department, all still of no avail through oneself attempting several different methods, the lighter points and occurs hyperemia, swelling, there is muscular death in severe one, fester.Round object has formed serious depression, and the tumor of finger is higher than the surface of being blocked object.Now, cut, cannot put to good use with common vice, power-off.Operation accidentally more easily occurs and, to being subject to the oppressive secondary injury that brings, take off not in time, indicator of trapped personnel also can face the danger of amputation.Existing instrument, size is larger, and destructive power is large, and equipment heaviness, carrying are mobile inconvenient, therefore, is necessary to develop a kind of portable cutting tool that can effectively reduce seeking help person and be subject to secondary injury.
Summary of the invention
The object of this invention is to provide a kind of portable pneumatic cutter, it is to adopt Compressed Gas as power source, by pneumatic cutting gun, driving emery wheel is formed by combining, be used for cutting the metals such as ring, can, the in the situation that of effective cutting metal object, do not produce obviously injury to the human body of indicator of trapped personnel, this equipment is simple and practical, portable safety.
The object of the invention is to be achieved through the following technical solutions: a kind of portable pneumatic cutter, for cutting the metal object of restriction human body or animal body, is characterized in that, comprise moveable compressed gas source, hand-hold type power converting unit, cutter unit, gas circuit connecting pipe and control module; Described gas source has pressure-control valve and pressure hose connector, described hand-hold type power converting unit has swivel head, this swivel head has the jig that fixing cutter unit is installed, and this hand-hold type power converting unit, take compressed gas pressure as power, drives cutter unit rotation; Described cutter unit is the Mini abrasive wheel of diameter 5-40mm, and it can be installed on swivel head by jig; Described gas circuit connecting pipe is pressure-resistant plastic flexible pipe, for connecting moveable compressed gas source, and control module and hand-hold type power converting unit; Moveable compressed gas source, hand-hold type power converting unit and gas circuit connecting pipe be by the dismountable connection of public type parent form connector, described control module control cutter unit rotating speed.
Described hand-hold type power converting unit is commercially available pneumatic cutting gun, for example, buys the pneumatic cutting gun that everyday wins pneumatic tool accessory Co., Ltd from Yiwu City;
Described moveable compressed gas source comprises that fire-fighting is with breathing gas cylinder, portable air compressor, compressed gas cylinder etc.;
The rotating speed of described Mini abrasive wheel is 1000-6000rpm;
Described emery wheel can be the shapes such as sheet, plate-like, column, step circle, selects the emery wheel of suitable shape to cut according to environment for use;
Described gas circuit connecting pipe can increase extension tube as required.
Another object of the present invention is the method for utilizing above-mentioned cutter to cut the metal object of restriction human body or animal body, and it comprises,
Use pressure hose to connect moveable compressed gas source and hand-hold type power converting unit, described hand-hold type power converting unit is pneumatic cutting gun, and described moveable compressed gas source is that fire-fighting is with breathing gas cylinder;
Select the emery wheel of suitable shape;
By jig, Mini abrasive wheel is fixed on the swivel head of pneumatic cutting gun, the rotating speed of described Mini abrasive wheel is 1000-6000rpm;
Control emery wheel cutting metal article.
Effective effect of the present invention is: adopting compressed gas cylinder equal pressure gas is power source, easily obtain in fire units, and be convenient to mobile, adopt Mini abrasive wheel as cutting tool, operating space is little, cutting process is easy to control, can not produce secondary injury to the human body contacting with metal object or animal body, in addition, this device presses hose coupling to be connected with air respiratorresuscitator in adopting, other end is connected with pneumatic cutting gun, with spanner, grinding wheel is arranged on cutting gun again, then open gas cylinder, opening cutting gun switch just can cut, simple and practical, detachable installing component, portable safety.
