Description
Technical field
The utility model relates to the stud handling instrument.
Background technology
Often run into installation or removal stud on workpiece aborning, because the restriction of the shape of stud does not have suitable general utility tool that it is pulled down or install from workpiece, can only be with some heavy method installation or removal, inefficiency loads and unloads of poor quality.As shown in Figure 1, now methods that adopt are to load onto two nuts 110 simultaneously at the non-end of packing into of stud 100 more, with common spanner two nuts are tightened each other, and then are used the spanner loading and unloading.Block top nut with spanner during installation, stud is packed into tighten, then two nuts are unclamped, unload two nuts.When workpiece unloads stud, also be to load onto two nuts earlier, with common spanner two nuts are tightened each other, block following nut with spanner then stud is unloaded.Whole process wastes time and energy, inefficiency.
The utility model content
In order to solve the problem of stud installation and removal difficulty, improve installation quality and removal efficiency, the utility model provides a kind of stud handling instrument.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
The stud handling instrument comprises that one adds high nut, and this internal thread that adds high nut matches with the external screw thread of stud to be loaded and unloaded, and the described high nut that adds is provided with handle;
Also comprise a movable bolt, the external screw thread on this movable bolt matches with the internal thread that adds high nut, and movable bolt is provided with handle.
Described handle is a pair of, is arranged at respectively to add the high nut both sides.
During use, earlier stud is screwed in workpiece with hand, because the strength of hand is limited, stud can not be tightened, can be spun on the stud this moment with adding high nut, and screw-in length is about half that adds high nut, then movable bolt is screwed in and add high nut, movable bolt is held out against with stud in adding high nut, and turning handle is fastened on stud on the workpiece again.Rotate in the opposite direction and fastening stud can be unloaded.After stud is fastening, unclamp movable bolt, can take off adding high nut.
The beneficial effects of the utility model are that it is flexible, convenient that this stud handling instrument uses, and improved operating efficiency, is particularly useful for the fastening installation of stud.
Description of drawings
Fig. 1 is a stud installation method schematic diagram commonly used;
Fig. 2 is the structural representation of the stud handling instrument that the utility model proposes.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 2, the stud handling instrument that the utility model proposes comprises and adds high nut 200, this internal thread that adds high nut 200 matches with the external screw thread of stud 100 to be loaded and unloaded, the described high nut 200 that adds is provided with handle 211 and handle 212, lays respectively at the both sides that add high nut 200;
Also comprise movable bolt 220, the external screw thread on this movable bolt 220 matches with the internal thread that adds high nut 200, and movable bolt 220 is provided with handle 221.
During use, with hand stud 100 is screwed in workpiece earlier, because the strength of hand is limited, stud can not be tightened, can be spun on the stud this moment with adding high nut 200, and screw-in length is about half that adds high nut, then movable bolt 220 is screwed in and add high nut 200, movable bolt is held out against with stud in adding high nut, and turning handle is fastened on stud on the workpiece again.Rotate in the opposite direction and fastening stud can be unloaded.After stud is fastening, unclamp movable bolt, can take off adding high nut.
It is flexible, convenient that this stud handling instrument uses, and improved operating efficiency, is particularly useful for the fastening installation of stud.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
