Description
Technical field
The utility model relates to mechanical wrench technical fields, are a kind of Chain wrenches.
Background technique
Chain wrench is also referred to as chain wrench at present comprising the chain that clamp handle and one end are connected with clamp handle.Chain wrench is working
When chain non-articulated end be it is free, do not fixed with clamp handle or hingedly, clamping, the rotation of pipe fitting are by pipe fitting and to wind its
Frictional force between chain is realized, but torsion is generated by the local gear wheel of clamp handle front end and the ratcheting power of chain, pincers
Handle does not have the position of applied force in tube surface.Therefore, Chain wrench not only can be to metal tube, and can be to ceramic tube
Part, thin-wall pipe, plastic pipe etc. are clamped, are rotated, and are not generated bite mark, are not lost tube surface.Technology is gathered around at present
Some Chain wrenches also cannot achieve installing and dismounting only for round pipe fitting, for space-constrained normal screws, separately
Outer traditional Chain wrench is caused high effort in installing and dismounting.
Summary of the invention
The utility model provides a kind of Chain wrench, overcomes the defects of the prior art, and can effectively solve non-
Round pipe fitting, and limited by space and the normal screws that are limited by size can not installing and dismounting the problem of and conventional chains
The laborious problem of spanner installing and dismounting.
The technical solution of the utility model is realized by following measures: a kind of Chain wrench, including pincers pipe, chain
With slope cap, clamp the groove that pipe upper end is right low left high, pincers pipe upper end is equipped with the slope cap that can seal groove, pincers pipe upper end left part with
The upper end of chain is hinged, slope cap upper end right part be equipped with and pincers pipe in the pilot hole that be connected to, in the middle part of pincers pipe outside equipped with
The limit hole being connected in pincers pipe.
Here is the further optimization and/or improvements to above-mentioned utility model technical solution:
Above-mentioned groove and pincers pipe lower end surface can be in 45 degree of angles.
Above-mentioned limit hole can be located at immediately below pilot hole.
Anti-skid design can be equipped on the outside of above-mentioned slope cap.
Above-mentioned pincers pipe lower part can be equipped with anti-slip rubber layer.
The utility model is structurally reasonable, easy to use, can solve by the winding of chain and the cooperation of slope cap non-circular
Pipe fitting and the installation and removal of normal screws for being limited by space, being limited by size, are penetrated by inclined slope cap with chain
Two levers are formed after being pierced by after pilot hole from limit hole, are had the characteristics that laborsaving, stable and easy.
Detailed description of the invention
Attached drawing 1 is the schematic view of the front view of the best embodiment of the utility model.
Attached drawing 2 is the overlooking structure diagram of attached drawing 1.
Coding in attached drawing is respectively as follows: 1 for pincers pipe, and 2 be chain, and 3 be slope cap, and 4 be pilot hole, and 5 be limit hole, and 6 be anti-
Sliding decorative pattern, 7 be anti-slip rubber layer.
Specific embodiment
The utility model is not limited by following embodiments, can technical solution according to the present utility model and actual conditions
Determine specific embodiment.
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to specification
The Butut mode of attached drawing 1 is described, such as: front, rear, top, and bottom, left and right positional relationship be according to Figure of description
Butut direction determine.
The utility model is further described below with reference to examples and drawings:
As shown in attached drawing 1,2, which includes pincers pipe 1, chain 2 and slope cap 3, and pincers 1 upper end of pipe is right low left high
Groove, pincers 1 upper end of pipe are equipped with the slope cap 3 that can seal groove, clamp 1 upper end left part of pipe and the upper end of chain 2 is installed together, slope
3 upper end right part of cap is equipped with the pilot hole 4 being connected to in pincers pipe 1, and 1 middle part outside of pincers pipe is equipped with the limit hole being connected to in pincers pipe 1
5.In use, the free end of chain 2 is pierced by after penetrating pilot hole 4 above the utility model from limit hole 5,
Pincers 1 lower end of pipe is held on the other hand, and the other hand catches 2 free end of chain being pierced by from limit hole 5, encloses by chain 2 and slope cap 3
At region realize disassembly is installed on to different component, by pull chain 2 free end come adjust enclosing region size.
Utility model is structurally reasonable, easy to use, can solve non-circular pipe fitting by the winding of chain 2 and the cooperation of slope cap 3, and
The installation and removal of the normal screws limited by space, limited by size penetrate pilot hole 4 with chain 2 by inclined slope cap 3
Two levers are formed after being pierced by afterwards from limit hole 5, are had the characteristics that laborsaving, stable and easy.
A kind of above-mentioned visualization ampoule opening of cap can be made further optimization and/or improvements according to actual needs:
As shown in attached drawing 1,2, groove and pincers 1 lower end surface of pipe are in 45 degree of angles.In use, by with groove phase
The inclined slope cap 3 matched can make the utility model form first lever, thus more laborsaving.
As shown in attached drawing 1,2, limit hole 5 is located at immediately below pilot hole 4.In use process, make pilot hole 4 and limit hole 5
Positioned at ipsilateral, penetrating after pilot hole 4 to be pierced by from limit hole 5 convenient for chain 2 makes the utility model form second lever, thus
It is more laborsaving.
As shown in attached drawing 1,2, anti-skid design 6 is equipped on the outside of slope cap 3.In use process, increase the frictional force of slope cap 3, just
In installation and removal component.
As shown in attached drawing 1,2, pincers 1 lower part of pipe is equipped with anti-slip rubber layer 7.In use, increase manpower and clamp pipe 1
Frictional force is easily installed and dismantles component.
The above technical characteristic constitutes the most preferred embodiment of the utility model, with stronger adaptability and best implementation
Effect can increase and decrease non-essential technical characteristic, according to actual needs to meet the needs of different situations.
