Description

一种新型裁纸刀结构 技术领域
本实用新型涉及裁纸领域，尤其涉及一种新型裁纸刀结构。
背景技术
裁纸刀在日常生活中只是一个刀具使用类的统称，在纸张裁剪的使用，过去我们曾经用细线贴紧折叠后的纸张边缘进行剪裁，也会通过刀片之类的刀具对纸张进行裁剪，目前，均被裁纸刀所替代，裁纸刀通过金属对纸张进行切割，其金属边缘并不锋利，而是采用力学紧密的接合使得纸张在金属作用力下被切割。
市面上普通的裁纸刀结构尾部因离杠杆支点太远，裁纸费力，难切断，易产生锯齿状。
实用新型内容
本实用新型主要解决的技术问题是提供一种裁纸省力，易切断，裁纸后头部和尾部一样整齐，且动作顺滑的新型裁纸刀结构，以解决上述现有技术存在的问题。
为解决上述技术问题，本实用新型采用的一个技术方案是：
一种新型裁纸刀结构，包括一底座，所述底座沿长度方向一侧的边缘处设有一压纸板，所述压纸板的外侧设有一下切刀，所述下切刀的刀锋向上，所述下切刀的一端连接有一上切刀，所述上切刀的刀锋与所述下切刀的刀锋相对设置，所述上切刀上设有一滚动轴承，所述上切刀的 横截面为弧形，所述上切刀与所述下切刀通过的一第一连接片连接，所述下切刀的另一端连接有一手压柄，所述手压柄上开设有一椭圆孔，所述压柄与所述下切刀通过一轴销连接，所述手压柄与所述轴销通过一第二连接片连接。
在本具体实施例中还包括，所述第一连接片与所述上切刀之间呈100°～160°夹角。
在本具体实施例中还包括，所述第二连接片与所述手压柄之间呈100°～160°夹角。
在本具体实施例中还包括，所述压纸板包括第一纸板和第二纸板，所述第一纸板和第二纸板相互垂直设置。
在本具体实施例中还包括，所述第二纸板下表面设有安装件，所述安装件上套设有弹簧。
在本具体实施例中还包括，所述底座沿长度方向一侧的边缘处开设有至少一圆孔。
在本具体实施例中还包括，所述滚动轴承为环形结构。
本实用新型的有益效果是：通过设置上切刀和手压柄，相当于在底座上设置了两个或两个以上的杠杆结构，当纸张裁切到尾部时，多杠杆结构发挥作用，当阻力不变时，动力可以减少70％以上，且裁切处的纸张头部和尾部一样整齐；通过设置滚动轴承，使其动作顺滑，裁切更加省力；同时，由于上切刀为弧形结构，可以改善裁纸的角度，使裁切在原有的基础上更加轻松。

图3是本实用新型压纸板的整体结构示意图。
图4是本实用新型上切刀的整体结构示意图。
图5是本实用新型手压柄的整体结构示意图。
图6是本实用新型滚动轴承的整体结构示意图。
具体实施方式
现参考附图1-6来进一步说明本实用新型的技术方案。
如附图1-6所示，本实用新型提供了一种新型裁纸刀结构，包括一底座100，底座100的两端分别设有第一平台110和第二平台120，其中，第一平台110和第二平台120高出底座100。具体地，底座100沿长度方向一侧的边缘处开设有两个圆孔130。
进一步地，所述底座100沿长度方向一侧的边缘处设有一压纸板200，压纸板200包括第一纸板210和第二纸板220，所述第一纸板210和第二纸板220相互垂直设置。其中，第一纸板210竖向设置，第二纸板220横向设置。第二纸板220下表面设有安装件221，所述安装件221上套设有弹簧222。同时，由于底座100沿长度方向一侧的边缘处开设有两个圆孔130，圆孔130用于穿设安装件221，使压纸板200在底座100上固定连接。如此一来，可以方便压纸板200的安装。同时，压纸板200可以防止手在裁切时，伤害到手指。在实际使用时，人们可以将手放置在第二纸板220上，由于第二纸板220下方设有弹簧222，方便压纸板 弹起。
进一步地，所述压纸板200的外侧设有一下切刀300，具体地，下切刀300为矩形。所述下切刀300的刀锋向上，所述下切刀300的一端连接有一上切刀400。所述上切刀400的刀锋与所述下切刀300的刀锋相对设置。通过设置上切刀400和手压柄500，相当于在底座100上设置了两个或两个以上的杠杆结构，当纸张裁切到尾部时，多杠杆结构发挥作用。根据杠杆原理，当阻力不变时，动力可以减少70％以上，且裁切处的纸张头部和尾部一样整齐。
进一步地，所述上切刀400上设有一滚动轴承410，滚动轴承410为环形结构。上切刀400的横截面为弧形，通过设置滚动轴承410，使其动作顺滑，裁切更加省力；同时，由于上切刀400为弧形结构，可以改善裁纸的角度，使裁切在原有的基础上更加轻松。所述上切刀400与所述下切刀300通过的一第一连接片420连接。具体地，第一连接片420与所述上切刀400之间呈100°～160°夹角。
进一步地，所述下切刀300的另一端连接有一手压柄500，手压柄500上开设有一椭圆孔510。上切刀400上的滚动轴承410穿设在椭圆孔510内，通过手压柄500控制上切刀400运动。其中，所述手压柄500与所述下切刀300通过一轴销520连接。所述手压柄500与所述轴销520通过一第二连接片530连接。其中，第二连接片530与手压柄500之间呈100°～160°夹角。
更为具体地，由于上切刀400为弧形，可以使上切刀400和下切刀300在裁切过程中夹角角度均匀，因为裁纸角度是影响裁纸效果的重要 因素，角度大，阻力小。而普通的裁纸刀开始裁纸时，角度大，阻力小，到尾部时角度接近0度，即上下切刀几乎平行。在本实用新型中，当裁纸刀裁切到尾部时，也有10度左右的夹角，减少了裁纸刀的阻力。
在本实用新型的描述中，需要理解的是，术语“内”、“上部”、“中部”、“侧面”、“上”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的单元或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制。
在本实用新型中，除非另有明确的规定和限定，术语“安装”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
以上仅为本实用新型的实施方式，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
