Description

A kind of chain type spanner
Technical field
The utility model is related to maintenance tool fields, more particularly, to a kind of chain type spanner.
Background technology
Bolt, nut, pipeline, the valve that each machine-building quotient is commonly designed out come in every shape, and with manufacturing Development and the improvement of process equipment, the shape of these parts is more diversified, the temporarily ununified standard of industry, although needle To the bolt or nut of each shape, pipeline or valve have the special spanner to match, pass through these Special pulls on the market Hand can install or remove bolt or nut, but if there is a large amount of variform bolt or nut, then need Various associated spanners, also, also need to accurately find matching pull for each different bolt or nut Hand, this will seriously affect the efficiency installed or removed to bolt or nut, and waste of resource and cost.And using commonly pulling When hand, pipe wrench load and unload pipeline, valve and various columnar components, equipment damage is easily caused, its normal use is influenced.And Its latch head is easily loosened with chain skidding in existing Chain wrench practical application, adjusts inconvenient for use, poor durability, work effect Rate is low.
Utility model content
In order to overcome the deficiencies of the prior art, the utility model proposes a kind of chain type spanners, can be widely applied to daily In being repaired in life, with material is simple, infusion of financial resources less, energy conservation and environmental protection, various types of nuts, nut and pipe can be suitable for The devices such as road, strong applicability is easy to adjust, durable, and work efficiency is high.
The technical solution adopted in the utility model is:A kind of chain type spanner, including handle, chain and be fixed at Handle front is used to press the sleeve of chain, the rear end of the chain to be fixedly connected with the rear portion of handle, and the front end of chain passes through set It is fixedly connected with the front of handle after cylinder, to form adjustable wrench jaw in the front end of handle, is vertically worn on the handle useful In the mandril for holding out against chain, the mandril is connect with handle threads, and the upper end of the mandril is provided with the set for rotating connection Ring, the lantern ring are set in the outside of chain.
Preferably, being provided with external screw thread on handle between the mandril and sleeve, the outer cover of handle is equipped with and outer spiral shell The traveling nut of line cooperation, traveling nut compress chain with sleeve cooperation.
Preferably, the lower end of the mandril is provided with the handle for facilitating rotation.
Preferably, the front end of the handle is provided with anti-slop serrations.
Preferably, the length of chain is more than the length of handle.
The beneficial effects of the utility model are:1, simple in structure, easy to use, the scope of application is wider, is applicable to a variety of Shape is pulled object;2, the upper end of mandril is provided with the lantern ring for rotating connection, to ensure chain will not tensioning or It is fallen in loose process;3, it is arranged with traveling nut on handle, can further pushes against chain, prevent from loosening.
Description of the drawings
Fig. 1 is the structural schematic diagram of the use of the new type.
Specific implementation mode
Illustrate that the embodiment of the utility model, those skilled in the art can be by these by particular specific embodiment below Content disclosed by specification understands other advantages and effect of the utility model easily.
It please refers to Fig.1.It should be clear that structure, ratio, size etc. depicted in this specification institute accompanying drawings, only coordinating The revealed content of specification, so that those skilled in the art understands and reads, being not limited to the utility model can be real The qualifications applied, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size It is whole, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, it should all fall and be taken off in the utility model In the range of the technology contents shown can be covered.Meanwhile in this specification it is cited as "upper", "lower", "left", "right", " in Between " and " one " etc. term, be merely convenient to being illustrated for narration, rather than to limit the enforceable range of the utility model, Relativeness is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable scope of the utility model.
A kind of chain type spanner, including handle 1, chain 2 and 1 front of handle is fixed at for pressing the set of chain 2 Cylinder 3, the length of chain 2 are more than the length of handle 1, and the rear end of chain 2 is fixedly connected with the rear portion of handle 1, and the front end of chain 2 is worn It is fixedly connected with the front of handle 1 after crossing sleeve 3, to form adjustable wrench jaw 4 in the front end of handle 1, is vertically worn on handle 1 It is useful for holding out against the mandril 5 of chain 2, mandril 5 is threadedly coupled with handle 1, and the upper end of mandril 5 is provided with the set for rotating connection Ring 6, lantern ring 6 are set in the outside of chain 2.External screw thread 7, the outer cover of handle 1 are provided on handle 1 between mandril 5 and sleeve 3 Equipped with the traveling nut 8 coordinated with external screw thread 7, traveling nut 8 compresses chain 2 with the cooperation of sleeve 3.
The lower end of mandril 5 is provided with the handle 9 for facilitating rotation.The front end of handle 1 is provided with anti-slop serrations 10.
When specifically used, adjustable wrench jaw 4 is sleeved on part to be operated, turning mandril 5 makes it hold out against chain 2, works as work Dynamic to pull mouth 4 and be locked after part to be operated, stopping turns mandril 5, and traveling nut 8 is rotated towards sleeve, anti-to compress chain 2 It only loosens, part to be operated is twisted to realize, when needing to use different parts, need to only adjust the position of mandril 5 It sets, strong applicability is easy to operate, and a tool solves the problems, such as the dismounting of plurality of specifications part.
The above embodiments are only illustrative of the principle and efficacy of the utility model, new not for this practicality is limited Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model All equivalent modifications completed under refreshing and technological thought or change, should be covered by the claim of the utility model.
