Described technical scheme is as follows:
A kind of oil drilling tools external screw thread thread protector handling instrument, described handling instrument comprises: the body of rod and be fixed in the working head of the described body of rod one end, groove phase clamping on described working head and the external screw thread thread protector, during groove clamping on described working head and the described external screw thread thread protector, the rotating shaft of the axis of the described body of rod and external screw thread thread protector is perpendicular.
Described working head is " ten " font working head, and it is formed by connecting by four monodentates, four described monodentates all with the external screw thread thread protector on the corresponding clamping of groove.
The cross section of described monodentate is square or rectangle.
The thickness of described monodentate is equal to or slightly less than the depth of groove on the external screw thread thread protector, and the width of described monodentate is equal to or slightly less than the recess width on the external screw thread thread protector.
The other end of the described body of rod corresponding with described working head fixed position also is provided with operating grip, and described operating grip is fixedly connected with the described body of rod.
Described working head is fixed on the described body of rod relatively by a connecting rod that runs through described rod end, and described working head is fixed in an end of described connecting rod, and the other end of described connecting rod is fixed with the dismounting handle.
The beneficial effect that technical scheme provided by the utility model is brought is:
Fix a working head by the end at the body of rod, working head is cooperated with groove clamping on the external screw thread thread protector, when needs are carried out the dismounting operation to oil drilling tools external screw thread thread protector, only need to be with in the groove on working head clamping and the external screw thread thread protector, then promote or the pulling body of rod, make the body of rod along the rotating shaft rotation of external screw thread thread protector, working head drives the rotation of external screw thread thread protector, by the positive and negative rotation working head, and then the dismounting of realization oil drilling tools external screw thread thread protector, it is simple in structure, easy to operate, the not high problem of operating efficiency has greatly improved the operating efficiency of oil drilling tools operation when having solved the loading and unloading of oil drilling tools male connection screw protective screw, has alleviated working strength.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
The utility model provides a kind of oil drilling tools external screw thread thread protector handling instrument, described handling instrument comprises: the body of rod and be fixed in the working head of the described body of rod one end, groove phase clamping on described working head and the external screw thread thread protector, described working head is when groove on the described external screw thread thread protector is connected, and the rotating shaft of the axis of the described body of rod and external screw thread thread protector is perpendicular.
As shown in Figure 1, working head wherein is " ten " font working head, and it is formed by connecting by four monodentates 11, and the cross section of monodentate 11 is square or rectangle, four monodentates 11 simultaneously with external screw thread thread protector 5 on groove 51 corresponding clampings.Also be provided with an operating grip 3 on the body of rod 2, operating grip 3 and working head 1 are individually fixed in the two ends of the described body of rod 2.The structure that forms cross recess on a kind of external screw thread thread protector end face is provided among the figure, and the monodentate 11 on the working head 1 is connected in the cross recess 51 of external screw thread thread protector, realizes the effective communication of moment of torsion.Wherein monodentate 11 width of cross working head 1 need be equal to or slightly less than cross recess 51 width on drilling tool external screw thread thread protector 5 end faces, its thickness is less than or equal to the degree of depth of drilling tool external screw thread thread protector 5 end face cross recess 51, otherwise working head 1 can't effectively snap in end face cross recess 51, thereby causes the moment of torsion transmission to lose efficacy.
