The content of the invention
The technical problems to be solved by the invention are to provide durable stretcher.
The technical solution 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 is less than the length of the hack lever, the end of two hack levers is exposed at the stretcher
Outside cloth;The stretcher cloth is worked out by cordage, and the cordage forms cotton synthetic fibre fibre bundle by some cotton synthetic fibre filaments,
The center of the cotton synthetic fibre fibre bundle is embedded with the polyester fiber tow being made of some polyester fiber yarns.
The beneficial effects of the invention are as follows:The stretcher of the present invention has higher tensile strength and wear-resisting property, and into
This is relatively low.
Based on the above technical solutions, the present invention can also be improved as follows.
Further, plurality of straps is further included, the more bandages are evenly distributed on two hack levers, the bandage
One end is connected with the hack lever, and the son of velcro is provided with the other end of the wherein bandage that a hack lever is connected
Face, the other end for the bandage being connected with another hack lever are provided with the generatrix of velcro.
Further, two lanyards are further included, two lanyards are separately positioned on the both ends of two hack levers, the extension
The both ends of rope are connected with two hack levers respectively.
Further, four rubber sleeves are further included, 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.

Embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
As depicted in figs. 1 and 2, a kind of stretcher, including two hack levers 1 and stretcher cloth 2 arranged in parallel, 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 is less than the length of the hack lever 1, the end of two hack levers 1 is exposed at outside the stretcher cloth 2;The stretcher
Cloth 2 is worked out by cordage, and the cordage forms cotton synthetic fibre fibre bundle 8 by some cotton synthetic fibre filaments, and the cotton synthetic fibre is fine
The center of dimension tow 8 is embedded with the polyester fiber tow 9 being made of some polyester fiber yarns.
The stretcher of the present invention has higher tensile strength and wear-resisting property, and cost is relatively low.
Based on the above technical solutions, the present invention can also be improved as follows.
Further, plurality of straps 3 is further included, the more bandages 3 are evenly distributed on two hack levers 1, described to tie up
It is connected with 3 one end with the hack lever 1, the other end for the bandage 3 being connected with wherein one hack lever 1 is provided with magic
The sub- face 4 of patch, the other end for the bandage 3 being connected with another hack lever 1 are provided with the generatrix 5 of velcro.
Further, two lanyards 6 are further included, two lanyards 6 are separately positioned on the both ends of two hack levers 1, institute
The both ends for stating lanyard 6 are connected with two hack levers 1 respectively.
Further, four rubber sleeves 7 are further included, 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 the description of the present invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width ",
" thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer ", " up time
The orientation or position relationship of the instruction such as pin ", " counterclockwise ", " axial direction ", " radial direction ", " circumferential direction " be based on orientation shown in the drawings or
Position relationship, is for only for ease of and describes the present invention and simplify description, rather than indicates or imply that signified device or element must
There must be specific orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
In addition, term " first ", " second " are only used for description purpose, and it is not intended that instruction or hint relative importance
Or the implicit quantity for indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can be expressed or
Implicitly include at least one this feature.In the description of the present invention, " multiple " are meant that at least two, such as two, three
It is a etc., unless otherwise specifically defined.
In the present invention, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " fixation " etc.
Term should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integrally;Can be that machinery connects
Connect or be electrically connected;It can be directly connected, can also be indirectly connected by intermediary, can be in two elements
The connection in portion or the interaction relationship of two elements, unless otherwise restricted clearly.For those of ordinary skill in the art
For, the concrete meaning of above-mentioned term in the present invention can be understood as the case may be.
In the present invention, unless otherwise clearly defined and limited, fisrt feature can be with "above" or "below" second feature
It is that the first and second features directly contact, or the first and second features pass through intermediary mediate contact.Moreover, 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 and is less than second feature.
In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show
The description of example " or " some examples " etc. means specific features, structure, material or the spy for combining the embodiment or example description
Point is contained at least one embodiment of the present invention or example.In the present specification, schematic expression of the above terms is not
It must be directed to identical embodiment or example.Moreover, particular features, structures, materials, or characteristics described can be in office
Combined in an appropriate manner in one or more embodiments or example.In addition, without conflicting with each other, the skill of this area
Art personnel can be tied the different embodiments or example described in this specification and different embodiments or exemplary feature
Close and combine.
Although the embodiment of the present invention has been shown and described above, it is to be understood that above-described embodiment is example
Property, it is impossible to limitation of the present invention is interpreted as, those of ordinary skill in the art within the scope of the invention can be to above-mentioned
