Abstract
The utility model provides a thread damage overhauling tool characterized in that the use configuration is similar to a 'bolt' and is identical with the standard attachment thread, with cutting edges being formed by the grooves opened in the axial direction. The main body of the end is designed into a biface body rotary handle; the periphery of the handle is oval and a circular hole is arranged in the middle of the handle, and the inner diameter of the screw thread is greater than that of standard thread 0.5-2.5 mm. The cutting edge is either a conical body or a cylindrical body, and is provided with either a cone screw or a cylinder screw assorted to the internal thread hole which is overhauled by thread damage overhauling tool. When the connection part can not be detached easily and can not be connected with a larger screw, the utility model looks much more important and irreplaceable. In our daily life, this thread damage overhauling tool can be used to repair and fasten screw thread conveniently, with the advantages of time saving, labour saving, simple and convenient use. In addition, the utility model is a practical tool for overhauling thread damages, and can be carried to overhaul thread damages at anytime and anyplace.
Description
Technical field
The utility model relates to a kind of connecting thread cutting element, and is particularly a kind of when internal thread becomes flexible, the screw thread stripped thread repair instrument of friction dropout.
Background technology
In haberdashery and hardware and light industry, go up multipurpose screw or screw connection between parts and part and the machine, because rising-heat contracting-cold, vibration or the operation of a machine, particularly resemble the easier screw that makes such as automobile, train, aircraft or steamer and farm machinery etc. and come off, can cause heavy cost when serious.In daily life, when repairing various stripped thread screw thread, because part and assembly or machine are not quick detachable, problems such as the bad grasp of hand drill reaming hole often cause the maintenance personal to repair difficulty, make troubles and bother to the user of service.I usually run into such problem in actual maintenance process, and the screw thread stripped thread of some special in addition parts can't repair, and repair rate is very high and can not get solving.
Summary of the invention
The utility model is based on above-mentioned situation, solves at present when standard screw and standard thread are damaged, and used screw and screw thread can't make problem fixedly connected between other parts, and a kind of screw thread stripped thread repair instrument is provided.
The utility model is achieved through the following technical solutions, comprise the standard connecting thread instrument that is threaded and adds following inner hole thread, its outer likeness in form one " bolt ", and offer groove vertically to form cutting edge, at one end head is provided with rotary handle and has circular hole.Wherein: the bottom diameter of described screw thread stripped thread repair instrument is 0.5～2.5 millimeter of overgauge bottom diameter; The described groove that has vertically is a bullet cutting edge instrument with the instrument that forms cutting edge; The described groove that has vertically is a cylinder cutting edge instrument with the instrument that forms cutting edge; The described groove that has vertically is the bullet cutting edge instrument that has three road grooves with the instrument that forms cutting edge; The described groove that has vertically is the cylinder cutting edge instrument that has three road grooves with the instrument that forms cutting edge; Described rotary handle is that a termination of body is the two sides body, and periphery has the rotary handle of circular hole for oval-shaped centre; And cone screw or the cylinder screw that matches with internal thread hole after the repair of screw thread stripped thread repair instrument arranged.
The utility model is by implementing technique scheme, following advantage and good effect are arranged: the outstanding characteristics of this stripped thread repair instrument are when both inconvenience dismountings of connecting portion, in the time of can not using screw than an original big specification to connect, seem particularly important and irreplaceable.In daily life, when repairing various stripped thread screw thread, because part and assembly or machine are not quick detachable, the bad grasp of hand drill reaming hole or can not use the time, can easily screw thread be repaired fasteningly with this screw thread stripped thread repair instrument, save time, laborsaving, simple and convenient, and carry repair whenever and wherever possible, be a kind of utility of repair stripped thread.
