Abstract
The utility model discloses a split-type wrench, and relates to the technical field of wrenches. The split-type wrench comprises two wrench bodies which are arranged oppositely. The two wrench bodies are respectively composed of a clamping portion and a wrench rod. The two wrench rods are connected through two screws in the length direction. A thread of each screw is evenly divided into two sections opposite in rotation direction in the length direction. The split-type wrench is different from a traditional shifting wrench and a traditional multi-hole wrench. According to the split-type wrench, the wrench bodies connected through the two screws are adopted, the distance between the clamping portions of the wrench can be adjusted, and therefore the split-type wrench can adapt to different types of nuts. The split-type wrench is firm in fixation, simple in structure, small in occupied space, flexible and convenient to use.
Description
Technical field
The utility model relates to field of tool, specifically a kind of split type spanner.
Background technology
At present, monkey wrench, because clamping gap is adjustable, easy to use, is therefore all used widely in each machined field and daily life.Conventional spanner is made up of moving jaw, regular jaw, adjusting nut etc. at present; moving jaw is arranged in the sliding tray of regular jaw, and by rotating adjusting nut, moving jaw can slide in sliding tray; moving jaw closed up or open, thereby adjusting jaw size.When use, spanner holding workpiece, pulls after certain angle, unclamps moving jaw, changes behind a position, then rotate adjusting nut on workpiece, adjusts clamping gap, makes moving jaw clamping work pieces again, continues twisting spanner, finally tightens workpiece.
On regular jaw, the cross sectional shape of sliding tray is generally circular hole at present, when twisting spanner tightens nut, workpiece can produce the reaction force that acts on sliding tray inner surface to regular jaw, after this power is decomposed, the component of its horizontal direction can produce outside thrust to sliding tray inner surface, this thrust makes sliding tray open to both sides, use after a period of time, can cause producing gap between moving jaw and regular jaw, while having caused monkey wrench to pull, moving jaw produces and rocks, the precision in impact clamping gap, causing clamping torsion reduces, user need to constantly readjust clamping gap, to adapt to the size of holding workpiece, cause many inconvenience to user, long-term use or the application of force even can cause the distortion of regular jaw when larger, reduce the service life of monkey wrench.In order to overcome above-mentioned defect, the general method adopting is by the two side thickening of sliding tray at present, but the method can not fundamentally be eliminated the generation in gap. and increased the material that manufacture spanner uses, improve manufacturing cost.
Utility model content
Technical problem to be solved in the utility model, it is the technical deficiency for above-mentioned existence, a kind of split type spanner is provided, it adopts two spanner splits that connect by screw rod, can regulate the spacing between spanner clamping part, to adapt to the nut of different model, fixation, simple in structure, the space taking is little, dexterous convenient.
The technical solution adopted in the utility model is: a kind of split type spanner is provided, comprises two spanner splits that are oppositely arranged; Described two spanner splits are by clamping part and wrenching bar composition; Two wrenching bars connect by two screw rods in the longitudinal direction; Described each screw rod screw thread be divided in the longitudinal direction contrary two sections of direction of rotation.Different from traditional shfting wrench and porous wrench, the utility model carrys out the nut of adaptive different model by two spanner splits can adjusting spacing, simple to operate, sound construction.
Further optimize the technical program, the end of each screw rod of split type spanner is equipped with " one " font hand lever.
Further optimize the technical program, the end of each wrenching bar of split type spanner is socketed with Anti-slip cover.Comfortableness when traditional shfting wrench thinks little of holding in handle design in order to alleviate overall weight, and be equipped with clamping part with the two ends of back-up wrench, root cannot arrange handle.In the technical program, on split type spanner, install the mode that directly contacts staff with metal material handle that Anti-slip cover has changed traditional shfting wrench and fixed wrench additional, improved user's comfortableness.
Further optimize the technical program, between the clamping part of two spanner splits of split type spanner, be provided with indicating arm and pull hand horn scale.
The beneficial effects of the utility model are: compare with back-up wrench with traditional shfting wrench, split type spanner simple in structure, fixed, can not cause because of mechanical gap clamping part loosening, nut that can adaptive different model, integrated more driving hole, and the space taking is less, operates simpler.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, spanner split; 2, clamping part; 3, wrenching bar; 4, screw rod; 5, screw thread; 6, " one " font hand lever; 7, Anti-slip cover; 8, indicating arm; 9, scale.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Fig. 1, split type spanner comprises two spanner splits 1 that are oppositely arranged; Two spanner splits 1 form by clamping part 2 and wrenching bar 3; Two wrenching bars 3 connect by two screw rods 4 in the longitudinal direction; The screw thread 5 of each screw rod 4 is divided into contrary two sections of direction of rotation in the longitudinal direction; The end of each screw rod 4 is equipped with " one " font hand lever 6; The end of each wrenching bar 3 is socketed with Anti-slip cover 7; Between the clamping part 2 of two spanner splits 1, be provided with indicating arm 8 and pull hand horn scale 9.
Using when split type spanner, can according to will be stubborn nut or the numbering of bolt, turn " one " font hand lever 6, make indicating arm 8 instructions arrive corresponding scale 9.The now numbering adaptation of the spacing between two clamping parts 2 and nut or bolt.Hand-held wrenching bar 3 can operate.
In the time of the spacing regulating between two clamping parts 2, in order to make two clamping part 2 keeping parallelisms, will make two wrenching bar 3 keeping parallelisms, so the number of turns that two screw rods 4 rotate wants consistent.
The above is the preferred embodiment of the present invention; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; likely to concrete size; or partial structurtes go out some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
