Abstract
The invention discloses a spanner with a chain. The spanner comprises an outer shell. A left rotatable chain wheel and a right rotatable chain wheel are installed at the two ends of the interior of the outer shell through pin shafts. The two chain wheels are linked through the chain. A square hole is formed in the middle of one of the chain wheels, a hexagon socket head sleeve matched with a nut is inserted into the square hole, and a square matched with the square hole is arranged on the outer side of the sleeve. The sleeve comprises a plurality of hexagon socket head sleeve bodies with different size models. A flat hole is formed in the center of the other chain wheel. A triangular tabulate spanner body is inserted into the flat hole. A front piece and a rear piece are clamped together to form the outer shell. A hexagon hole corresponding to a hexagon socket head hole of one of the chain wheels is formed in the outer shell, and a long-strip-shaped hole corresponding to the flat hole of the other chain wheel is further formed in the outer shell. The spanner with the chain has the beneficial effects of being simple in structure, capable of tightening or loosening screws in narrow spaces, convenient to use and practical.
Description
(1) technical field
The present invention relates to a kind of instrument tightened up a screw, particularly to a kind of spanner with chain。
(2) background technology
In life, screwdriver can only vertically use, it is impossible to laterally uses, and at two closer planks or there is a screw in a relatively narrower space, the words using traditional screwdriver can be very inconvenient。
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of convenient and practical spanner with chain。
The present invention is achieved through the following technical solutions:
The spanner with chain of the present invention, it is characterized in that: include shell, enclosure two ends are provided with two, rotating left and right sprocket wheel by bearing pin, two sprocket wheels are interlocked by chain, it is provided with square hole in the middle part of one of them sprocket wheel, the hexagon socket head sleeve coincideing with nut it is inserted with in square hole, it it is the square coincideing with square hole outside sleeve, sleeve includes several sleeves that hexagon socket head size model is different, another centre of sprocket is provided with flat hole, triangle flat plate shape spanner it is inserted with in flat hole, shell is fastened togather by front and back two panels, shell is provided with the hex hole in the hexagon socket head hole of a corresponding sprocket wheel, shell is additionally provided with the elongate holes in the flat hole of another sprocket wheel corresponding, and shell side is provided with the oil filler point of alignment chain, shell is additionally provided with the LED for illuminating and switch, a battery is had to be connected with LED and switch, battery is arranged in the grease proofing sealing shroud that enclosure is fixing。
The spanner with chain of the present invention, at two closer planks or when tightening up a screw or tear screw open in a relatively narrower space, inside nook, corner, light often ratio is dark, therefore can illuminate by LED。
Therefore, the invention has the beneficial effects as follows: this spanner with chain, simple in construction, the screw at narrower place, space can be stepped up or loosen, convenient and practical。By the hexagon socket head borehole jack of left side sprocket wheel on the nut to install or remove, rotating triangular planar tabular spanner and drive right side sprocket wheel to rotate, by the transmission of chain, drive left side sprocket wheel to rotate, the hexagon socket head pore area of left side sprocket wheel moves nut rotation。Sleeve includes several sleeves that hexagon socket head size model is different, it is adaptable to the nut that big ting model is different。
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated。
Accompanying drawing 1 is the front view schematic diagram of the present invention；Accompanying drawing 2 is the top view schematic diagram of the present invention。
In figure, 1 shell, 2 sprocket wheels, 3 chains, 4 sleeves, 5 handles, 6 apertures, 7 flat holes, 8LED lamp, 9 bearing pins。
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention。
The spanner with chain of the present invention, including shell 1, enclosure two ends are provided with two, rotating left and right sprocket wheel 2 by bearing pin 9, two sprocket wheels are interlocked by chain 3, it is provided with square hole in the middle part of one of them sprocket wheel, the hexagon socket head sleeve 4 coincideing with nut it is inserted with in square hole, it it is the square coincideing with square hole outside sleeve, sleeve includes several sleeves that hexagon socket head size model is different, another centre of sprocket is provided with flat hole 7, triangle flat plate shape spanner 5 it is inserted with in flat hole, shell is fastened togather by front and back two panels, shell is provided with the hex hole in the hexagon socket head hole of a corresponding sprocket wheel, shell is additionally provided with the elongate holes in the flat hole of another sprocket wheel corresponding, and shell side is provided with the oil filler point 6 of alignment chain, shell is additionally provided with the LED 8 for illuminating and switch, a battery is had to be connected with LED and switch, battery is arranged in the grease proofing sealing shroud that enclosure is fixing。
Adopt the spanner with chain of the present invention, shell 1 can be put in narrow space, screw 4 is directed at screw engaging, handle 5 is injected the screw 4 of the other end again, swing handle 5, two sprocket wheels 2 are made to carry out fiting or loosening screw under the interlink function of chain 3, shell 1 is clamp-close type, can opening renewal part, aperture 6 is when shell is not switched on, and the convenient chain 3 to inside instills lubricating oil, keep the smoothness used, handle 5 is provided with hand grip part, can be easy to hands right with holding of handle 5, in order to go to open screw by less power。Therefore, the invention has the beneficial effects as follows: this spanner with chain, simple in construction, the screw at narrower place, space can be stepped up or loosen, convenient and practical。
