The content of the invention
The technical problem to be solved is to provide durable stretcher.
The technical scheme that the present invention solves above-mentioned technical problem is as follows:A kind of stretcher, including two arranged in parallel
Hack lever and stretcher cloth, the stretcher cloth are arranged between two hack levers, the both sides of the stretcher cloth respectively with described in two
Hack lever connects, and the length of the stretcher cloth makes the end of two hack levers be exposed at the stretcher less than the length of the hack lever
Outside cloth;The stretcher cloth is worked out by cordage, and the cordage constitutes cotton synthetic fibre fibre bundle by some cotton synthetic fibre cellosilks,
The center of the cotton synthetic fibre fibre bundle is embedded with the polyster fibre tow being made up of some polyester fiber yarns.
The invention has the beneficial effects as follows:The stretcher of the present invention has higher tensile strength and an anti-wear performance, and into
This is relatively low.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, also including plurality of straps, many bandages are evenly distributed on two hack levers, the bandage
One end is connected with the hack lever, and the other end of the bandage being connected with wherein one hack lever is provided with the son of VELCRO
Face, the other end of the bandage being connected with another hack lever are provided with the generatrix of VELCRO.
Further, also including two lanyards, two lanyards are separately positioned on the two ends of two hack levers, the extension
The two ends of rope are connected with two hack levers respectively.
Further, also including four rubber sleeves, four rubber sleeves are respectively sleeved at four ends of two hack levers
In portion.
Further, the rubber sleeve is the tubular structure of one end closure.

Specific embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
It is non-for limiting the scope of the present invention.
As depicted in figs. 1 and 2, a kind of stretcher, including two hack levers 1 arranged in parallel and stretcher cloth 2, the stretcher
Cloth 2 is arranged between two hack levers 1, and the both sides of the stretcher cloth 2 are connected with two hack levers 1 respectively, the stretcher
The length of cloth 2 makes the end of two hack levers 1 be exposed at outside the stretcher cloth 2 less than the length of the hack lever 1;The stretcher
Cloth 2 is worked out by cordage, and the cordage is made up of cotton synthetic fibre fibre bundle 8 some cotton synthetic fibre cellosilks, and the cotton synthetic fibre is fine
The center of dimension tow 8 is embedded with the polyster fibre tow 9 being made up of some polyester fiber yarns.
The stretcher of the present invention has higher tensile strength and anti-wear performance, and cost is relatively low.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, also including plurality of straps 3, many bandages 3 are evenly distributed on two hack levers 1, described to tie up
It is connected with the hack lever 1 with 3 one end, the other end of the bandage 3 being connected with wherein one hack lever 1 is provided with magic
The sub- face 4 of patch, the other end of the bandage 3 being connected with another hack lever 1 are provided with the generatrix 5 of VELCRO.
Further, also including two lanyards 6, two lanyards 6 are separately positioned on the two ends of two hack levers 1, institute
The two ends for stating lanyard 6 are connected with two hack levers 1 respectively.
Further, also including four rubber sleeves 7, four rubber sleeves 7 are respectively sleeved at four of two hack levers 1
On end.
Further, the rubber sleeve 7 is the tubular structure of one end closure.
In describing the invention, it is to be understood that term " " center ", " longitudinal direction ", " horizontal ", " length ", " width ",
" thickness ", " on ", D score, "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outward ", " up time
The orientation or position relationship of the instruction such as pin ", " counterclockwise ", " axial direction ", " radial direction ", " circumference " be based on orientation shown in the drawings or
Position relationship, is for only for ease of the description present invention and simplifies description, rather than indicates or imply that the device or element of indication must
With specific orientation, with specific azimuth configuration and operation, therefore must be not considered as limiting the invention.
Additionally, term " first ", " second " are only used for describing purpose, and it is not intended that indicating or implying relative importance
Or the implicit quantity for indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can express or
Implicitly include at least one this feature.In describing the invention, " multiple " are meant that at least two, such as two, three
It is individual etc., unless otherwise expressly limited specifically.
In the present invention, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection ", " fixation " etc.
Term should be interpreted broadly, for example, it may be fixedly connected, or be detachably connected, or it is integral;Can be that machinery connects
Connect, or electrically connect;Can be joined directly together, it is also possible to be indirectly connected to by intermediary, can be in two elements
The connection in portion or the interaction relationship of two elements, unless otherwise clearly restriction.For one of ordinary skill in the art
For, above-mentioned term concrete meaning in the present invention can be understood as the case may be.
In the present invention, unless otherwise clearly defined and limited, fisrt feature second feature " on " or D score can be with
It is the first and second feature directly contacts, or the first and second features is by intermediary mediate contact.And, fisrt feature exists
Second feature " on ", " top " and " above " but fisrt feature are directly over second feature or oblique upper, or be merely representative of
Fisrt feature level height is higher than second feature.Fisrt feature second feature " under ", " lower section " and " below " can be
One feature is immediately below second feature or obliquely downward, or is merely representative of fisrt feature level height less than second feature.
In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show
Example ", or the description of " some examples " etc. mean specific features with reference to the embodiment or example description, structure, material or spy
Point is contained at least one embodiment or example of the present invention.In this manual, to the schematic representation of above-mentioned term not
Identical embodiment or example must be directed to.And, the specific features of description, structure, material or feature can be with office
Combined in one or more embodiments or example in an appropriate manner.Additionally, in the case of not conflicting, the skill of this area
