Abstract
The utility model relates to a tool spanner specifically is a sprocket drive spanner. The problem of traditional spanner that exists among the prior art be difficult to play a role in narrow and small space is solved. The chain wheel is sleeved with a chain, and a wrench head is arranged on a central shaft of one chain wheel. Or a mounting seat can be fixed on the central shaft of the chain wheel, and a wrench head is sleeved on the mounting seat. The utility model discloses a transmission of moment is accomplished in the combination of gear and chain, can avoid traditional spanner can only leave the drawback that uses under the condition in rotation space near the nut, makes it can install or dismantle screw, bolt, nut etc. in a flexible way in narrow and small passageway.
Description
Technical field
The utility model relates to a kind of tool wrench, is specially a kind of chain gear transmission spanner.
Background technology
The spanner that uses all needs than the high rotation angle degree when operation, so generally only be suitable for using in bigger operating space is arranged at present.Under the situation of some special constructions, be in just in the narrow and small crack as screw, in the time of perhaps in a longer and narrower passage, traditional spanner is difficult to bring into play its effect because its rotation is restricted.
Summary of the invention
The utility model is for the problem that solves the conventional spanner that exists in the prior art and be difficult to play a role in small space and a kind of chain gear transmission spanner is provided.
The utility model is realized by following technical scheme: a kind of chain gear transmission spanner, comprise bracing frame, and be positioned at the sprocket wheel at bracing frame two ends, be with chain on the sprocket wheel, one of them centre of sprocket axle is provided with driving end.
Also can be on the centre of sprocket axle fixed mounting, be with driving end on the mount pad.When practical operation is used, model according to the nut of reality, select suitable driving end, one end that will have the sprocket wheel of driving end then extend in the affined working face of gallery inside lock, drive another sprocket rotation by external force again, this power passes to the sprocket wheel that has driving end by chain, and sprocket wheel drives the driving end rotation can be with rotations such as nut or bolts.
Compared with prior art, the utility model has adopted two sprocket wheels has been set at the bracing frame two ends, and on sprocket wheel the assembly wrench head, the structure that connects by chain between the sprocket wheel, finish the transmission of moment by the combination of gear and chain, the drawback that can avoid traditional spanner under near the situation that leaves rotation space the nut, to use, make its can be in narrow and small passage installation or removal screw, bolt, nut etc. neatly.

The specific embodiment
A kind of chain gear transmission spanner comprises bracing frame 4, is positioned at the sprocket wheel 1,6 at bracing frame two ends, is with chain 3 on the sprocket wheel, and one of them sprocket wheel 1 central shaft is provided with driving end.Sprocket wheel is contained on the bracing frame by rotating shaft.
As shown in Figure 2, use for convenience, bracing frame 4 can be made of two pipes arranged side by side, and two sprocket wheels are installed in the two ends of pipe respectively, and chain 3 places in the pipe.Hand just can directly be held pipe and not hinder the activity of chain during use.
Be fixed with mount pad 2 on sprocket wheel 1 central shaft, be with driving end on the mount pad.Mount pad is a polygon, is generally hexagon, and driving end has multiple model, loads onto different driving ends and can do spanners uses such as interior six sides, outer six sides, can be suitable for the bolt of different size.
According to the size of working space, the size of flexibly changing sprocket wheel 1; According to the size of the application of force, can change the gearratio of two sprocket wheels flexibly.
Be fixed with driving shaft 5 in another sprocket wheel 6 in the heart, driving shaft is a polygon, other spanner can be entangled driving shaft when needing manual operation, again rotation.It mainly is the spanner that applies external force in order to cooperate.The center of sprocket wheel 6 also can be set to polygon inner groovy in addition, is used with the application of force spanner that adapts to other shape.
