Abstract
The utility model relates to a chain type universal wrench, which is characterized in that a special chain is connected with a fine tuning screw rod. After a hole of the fine tuning screw rod of a handle is penetrated, a washer is positioned, a fine tuning nut is screwed, and one side of the handle is provided with a chain wheel and a wheel stopping stopcock. When the wheel stopping stopcock is opened, and after engaged and fitted, the chain and the chain wheel pass through a chain penetrating hole of the handle. A workpiece is enwrapped by a chain, the wheel stopping stopcock is pushed, and the fine tuning nut is tightly screwed. In the length of a special chain, the chain type universal wrench which the utility model relates to can be used for pipes with various calibres in larger range, screw bolts with various sizes, and the installation and the dismounting work of nuts.
Description
This reality is novel to be related to and a kind ofly can hold various bore pipes and all size bolt, nut tightly in bigger scope, mounts and dismounts the instrument of operation.
At present the installation and removal pipe need use pipe vice, and mounting and dismounting bolt, nut need be with various fork spanner or adjustable wrench, though pipe vice and adjustable wrench have certain adjustable range, scope is little.So when mounting and dismounting pipeline and bolt, nut operation, need many pipe vices that vary in size and various spanner usually, very inconvenience is especially carried out operation and is more felt inconvenient in field work or the military operation.
The purpose of the utility model chain type universal spanner be for provide a kind of can be in bigger scope the pipe of the multiple bore of installation or removal and bolt, the nut of plurality of specifications, can integrate a plurality of pipe vices and adjustable wrench facility and practical tool.
The technical scheme of the utility model chain type universal spanner is achieved like this; Connect the fine setting screw rod with special chain one end, the rearmounted packing ring in regulating rod hole that the fine setting screw rod passes handle screws on fine-tuning nut, other side one sprocket wheel of handle reaches only takes turns plug, pass through by wearing the chain hole after chain and the sprocket engagement, with sprocket wheel with only take turns plug and fine setting screw rod, fine-tuning nut tighten up chain, hold pipe, bolt or nut tightly and carry out the installation or removal operation.
The advantage of the utility model chain type universal spanner is: special chain is at sprocket wheel, only take turns under the effect of plug, fine setting screw rod, fine-tuning nut, can hold pipe tightly, the workpiece of different cross section such as hex bolts, hex nut shape to be installed or dismounting can be by the big or small free adjustment of workpiece in the bigger scope in the length of special chain.The utility model chain type universal spanner is simple in structure, easy to carry, the scope of application is wide and convenient and reliable, can be widely used in the installation and removal operation.
The utility model chain type universal spanner embodiment is described further in conjunction with the accompanying drawings:
Fig. 1 is a chain type general-purpose wrench structural representation.
As shown in Figure 1, the chain type universal spanner is connected with an end of special chain (2) by fine setting screw rod (1), passes the regulating rod hole (8) of handle (5), puts a packing ring (7) and screws on fine-tuning nut (6); In addition side one sprocket wheel (3) of handle (5) and only take turns plug (4) penetrates after chain and the sprocket engagement in the chain hole (9); Embrace and only take turns plug (4) locking sprocket wheel and chain on the workpiece pusher, screw fine-tuning nut (6).At this moment, workpiece to be installed or dismounting is held tightly by special chain, can conveniently carry out the installation or removal operation.
Claims (1)
- A kind of utility model chain type universal spanner, it is characterized in that with fine setting screw rod (1), fine-tuning nut (6) and packing ring (7), special chain (2), sprocket wheel (3), only taking turns plug (4), handle (5), combine a kind ofly can hold the instrument that multiple bore pipe and plurality of specifications bolt, nut mount and dismount operation tightly.
