Abstract
The utility model relates to a pair of step-by-step tightening canvas pliers comprising a first plier body, a second plier body, a spring and a rivet. The canvas pliers are characterized in that handgrips of the first plier body and the second plier body are respectively provided with a declivate surface connected to a jaw; a through hole is respectively arranged near the jaws of the two plier bodies and are connected by the rivet; a plurality of stepped supporting points are designed at the front end of the first plier body. The utility model aims to overcome the deficiencies of the prior art and provides a pair of step-by-step tightening canvas pliers so as to enable users to conveniently and accurately stretch and assemble canvas.
Description
[technical field]
The utility model relates to a kind of auxiliary implement of drawing, relates in particular to the canvas pliers that is used for oil painting.
[background technology]
The conventional tool of adorning painting canvas that stretches tight is hand hammer and shoe tack, uses not only to require great effort but also inconvenient, and single people is difficult to finish the dress that stretches tight.
Along with the appearance successively of specific purpose tools such as rifle formula stapler, nail rifle, wide mouth pincers, the feasible dress painting canvas that stretches tight is laborsaving many.But when being to use these instruments, the dress person that still needs to stretch tight possesses certain experience, because if when dress of stretching tight is firmly uneven, can cause the picture frame distortion, and if canvas holds and tightly do not make the painting canvas displacement easily.Often need to tighten again and again painting canvas when especially using existing wide mouth pincers to stretch tight dress, can exert oneself inequality and cause the picture frame distortion.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of canvas pliers of tightening step by step is provided, to make user's dress painting canvas that can make things convenient for, stretch tight accurately.
To achieve these goals, the technical scheme taked of the utility model is:
A kind of canvas pliers of tightening step by step comprises: first caliper, second caliper, spring, rivet, it is characterized in that the handle of described first caliper, second caliper establishes all gradually that the inclined-plane is connected to jaw, and such design is convenient to hand and is taken; Nearly jaw place is provided with through hole respectively on two calipers, connects by rivet; And the Front-end Design of first caliper has some stepped fulcrums, can painting canvas be tightened step by step successively by these fulcrums when stretching tight painting canvas, realizes convenient, the accurate fixing purpose of painting canvas.The above-mentioned canvas pliers of tightening step by step; the handle of described two calipers is asymmetric; wherein the radian on the gradually inclined-plane of the handle of second caliper is less than first caliper, and should guarantee that canvas pliers clamps the time angle β of the jaw of the gradually inclined-plane of second caliper and first caliper greater than 180 °.
The above-mentioned canvas pliers of tightening step by step is provided with spring between two handles, and when first caliper, when second caliper closes up, the elastic potential energy that spring produces by compression discharges when openhanded opening, and makes to tighten the canvas pliers jaw step by step and open convenient the use automatically; The one side that two caliper jaws are relative is the undaform surface, and two jaws mesh just during clamping, thereby makes canvas be difficult for sliding transfer.
Good effect of the present utility model is:
1, tightens the painting canvas that canvas pliers can clamp the dress that need stretch tight step by step, prevent the painting canvas displacement.
2, tighten the canvas pliers dress painting canvas that can accurately stretch tight step by step, prevent the picture frame distortion.
[description of drawings]
Accompanying drawing 1 is a structural representation of the present utility model.
Label in the accompanying drawing is respectively:
1, first caliper, 2, second caliper, 3, handle,
4, rivet, 5, spring, 6, jaw,
7, through hole.
[specific embodiment]
Provide the specific embodiment of the present utility model below in conjunction with accompanying drawing, but the utility model is not limited to following embodiment.
The utility model comprises: first caliper 1, second caliper 2, spring 5, rivet 4, it is characterized in that the handle 3 of described first caliper 1, second caliper 2 establishes all gradually that the inclined-plane is connected to jaw 6, and such design is convenient to hand and is taken; The Front-end Design of the jaw 6 of first caliper 1 has some stepped fulcrums (as two); Be provided with spring 5 between two handles 3, when first caliper 1, when second caliper 2 closes up, spring 5 is compressed and the elastic potential energy that produces discharges when openhanded opening, and makes to tighten the canvas pliers jaw step by step and open convenient the use automatically; Nearly jaw 6 places are provided with through hole 7 respectively on two calipers, connect by rivet 4, and the jaw 6 of two calipers can adopt wide mouth design, but its width 5-20cm, jaw 6 relative one sides are the undaform surface, and jaw 6 meshes when clamping just, thereby makes canvas be difficult for sliding transfer.
The gradually inclined-plane of the handle 3 of two calipers is set to asymmetric, and wherein the radian on the gradually inclined-plane of the handle 3 of second caliper is less than first caliper 1, and should guarantee that canvas pliers clamps the time angle β of the jaw 6 of the gradually inclined-plane of second caliper 2 and first caliper greater than 180 °.
Embodiment 1:
When stretching tight the dress painting canvas, hold the utility model and adopt first caliper 1 under the mode of holding with a firm grip, utilize the ladder of the outside one side of the jaw 6 of first caliper 1, earlier with the position after ladder as fulcrum, tighten painting canvas, if relatively pine or painting canvas area are difficult to situation about once tightening more greatly to run into the painting canvas quality, can raise handle 3 slightly, with the position the preceding ladder as fulcrum, tighten painting canvas once more, realize locating layer by layer the purpose of painting canvas, avoided using traditional canvas pliers to stretch tight and adorned the shortcoming that easily makes the picture frame distortion.
Claims (4)
1. tighten canvas pliers step by step for one kind, comprising: first caliper, second caliper, spring, rivet is characterized in that the handle of described first caliper, second caliper establishes all gradually that the inclined-plane is connected to jaw; Nearly jaw place is provided with through hole respectively on two calipers, connects by rivet, and the Front-end Design of first caliper has some stepped fulcrums.
2. the canvas pliers of tightening step by step as claimed in claim 1; the handle that it is characterized in that two calipers is asymmetric; wherein the radian on the gradually inclined-plane of the handle of second caliper is less than first caliper, and should guarantee that canvas pliers clamps the time angle β of the jaw of the gradually inclined-plane of second caliper and first caliper greater than 180 °.
3. the canvas pliers of tightening step by step as claimed in claim 1 is characterized in that the relative one side of jaw of two calipers is the undaform surface, and two jaws mesh just during clamping.
