Description

一种手持力度均匀的工业用锉刀 技术领域
本实用新型涉及工业锉削加工用刀具领域，具体为一种手持力度均匀的工业用锉刀。
背景技术
工业刀具是机械制造中用于切削加工的工具，又称切削工具。绝大多数的刀具是机用的，但也有手用的。由于机械制造中使用的刀具基本上都用于切削金属材料，所以刀具一词一般就理解为金属切削刀具。刀具按工件加工表面的形式可分为五类：加工各种外表面的刀具包括车刀、刨刀、铣刀、外表面拉刀和锉刀等；孔加工刀具包括钻头、扩孔钻、镗刀、铰刀和内表面拉刀等；螺纹加工刀具包括丝锥、板牙、自动开合螺纹切头、螺纹车刀和螺纹铣刀等；齿轮加工刀具包括滚刀、插齿刀、剃齿刀、锥齿轮和拉刀等；切断刀具包括镶齿圆锯片、带锯、弓锯、切断车刀和锯片铣刀等。
其中，锉刀是用碳素工具钢T12或T13经热处理后，再将工作部分淬火制成的,是一种小型生产工具。锉刀表面上有许多细密刀齿、条形，是用于锉光工件的手工工具，用于对金属、木料、皮革等表层做微量加工。
目前，市面上的锉刀种类繁多，按用途分有：普通钳工锉、木锉、什锦锉、专用锉刀；按剖面形状分有平锉、方锉、半圆锉、圆锉、三角锉、菱形锉和刀形锉等；按锉纹形式分单纹锉和双纹锉两种；此外，还有表面电镀金刚石粉的金刚石锉刀。但是这些各式各样的锉刀，在使用时导致锉削不光滑不平整时有发生，这是由于它们有一个通病，即单侧握柄；很多工人师傅在 使用锉刀时习惯双手握持，但是有一头握持的是锉刀部分而不是手柄，这就极易导致用力不均或刮伤手掌，或者需佩戴厚棉手套导致手上用力感觉失灵，因此市场上急需一种手持力度均匀的工业用锉刀来解决这些问题。
实用新型内容
本实用新型的目的在于提供一种手持力度均匀的工业用锉刀，以解决上述背景技术中提出的单握柄锉刀在使用时不能保证锉削工作用力均匀的问题。
为实现上述目的，本实用新型提供如下技术方案：一种手持力度均匀的工业用锉刀，包括锉刀，所述锉刀的两端分别设置有刀柄一和刀柄二。
优选的，所述锉刀的两端均设置有相同的连接部；所述刀柄一的一端的宽度比所述刀柄一的另一端的宽度宽，所述刀柄一比另一端宽的一端的中间设置有孔，所述刀柄一的所述孔与所述锉刀的一端的所述连接部固定连接；所述刀柄二的一端的宽度比所述刀柄二的另一端的宽度窄，所述刀柄二比另一端窄的一端的中间设置有与所述刀柄一的所述孔相同的孔，所述刀柄二的所述孔与所述锉刀的另一端的所述连接部固定连接。
优选的，所述锉刀的四个侧面均设置有刀齿，所述连接部处没有设置所述刀齿。
优选的，所述刀柄一的三个侧面分别与所述刀柄一的两个端面均垂直，所述刀柄一的另一个侧面的所在平面与所述另一个侧面相对的侧面的所在平面之间的小于90度的夹角为10-30度；所述刀柄二的三个侧面分别与所述刀柄二的两个端面均垂直，所述刀柄二的另一侧面的所在平面与所述另一侧面相对的侧面的所在平面之间的小于90度的夹角为10-30度；所述刀柄一的两 个端面与所述刀柄二的两个端面平行，所述刀柄一的所述另一个侧面与所述刀柄二的所述另一侧面平行，所述刀柄一的三个侧面与所述刀柄二的三个侧面分别平行。
优选的，所述刀柄一的所述另一个侧面和所述另一个侧面相对的侧面上分别设置有四个间隔相同的刀柄一凹槽。
优选的，所述刀柄二的所述另一侧面和所述另一侧面相对的侧面上分别设置有四个间隔相同的刀柄二凹槽。
与现有技术相比，本实用新型的有益效果是：
1.该手持力度均匀的工业用锉刀的两端均设置有刀柄，可以单手使用，也可以双手同时使用，双手使用时，该手持力度均匀的工业用锉刀可以令使用者更容易控制双手力度，解决了单握柄锉刀在使用时不能保证锉削工作用力均匀的问题，可以使对工件的加工更加精细，有利于提高产品质量。
2.该手持力度均匀的工业用锉刀的两端的刀柄分别设置有一个水平握边和一个倾斜握边，双手四指同时握持水平握边时，可以令锉刀水平工作，双手四指同时握持倾斜握边时，可以令锉刀与加工工件成一定角度工作，实用性更加广泛，且使用更偏向符合人体工学。
附图说明
图1为本实用新型的一种实施例的主视图；
图2为图1所示实施例的一种工作状态示意图；
图3为本实用新型的另一种实施例的主视图；
图4为图3所示实施例的一种工作状态示意图。
图中：1、锉刀；11、刀齿；2、刀柄一；21、刀柄一凹槽；3、刀柄二； 31、刀柄二凹槽；32、突起块。
具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。
实施例一：
请参阅图1和图2，本实用新型提供的一种实施例：一种手持力度均匀的工业用锉刀，包括锉刀1，锉刀1的两端分别设置有刀柄一2和刀柄二3。
进一步，锉刀1的两端均设置有相同的连接部；刀柄一2的一端的宽度比刀柄一2的另一端的宽度宽，刀柄一2比另一端宽的一端的中间设置有孔，刀柄一2的孔与锉刀1的一端的连接部固定连接；刀柄二3的一端的宽度比刀柄二3的另一端的宽度窄，刀柄二3比另一端窄的一端的中间设置有与刀柄一2的孔相同的孔，刀柄二3的孔与锉刀1的另一端的连接部固定连接。
进一步，锉刀1的四个侧面均设置有刀齿11，连接部处没有设置刀齿11。
进一步，刀柄一2的三个侧面分别与刀柄一2的两个端面均垂直，刀柄一2的另一个侧面的所在平面与另一个侧面相对的侧面的所在平面之间的小于90度的夹角为10-30度；刀柄二3的三个侧面分别与刀柄二3的两个端面均垂直，刀柄二3的另一侧面的所在平面与另一侧面相对的侧面的所在平面之间的小于90度的夹角为10-30度；刀柄一2的两个端面与刀柄二3的两个端面平行，刀柄一2的另一个侧面与刀柄二3的另一侧面平行，刀柄一2的三个侧面与刀柄二3的三个侧面分别平行；倾斜的侧面可以在握持时令锉刀1与待加工工件成一定角度工作，使本实用新型的实用性更加广泛，且使用更 偏向符合人体工程学。
进一步，刀柄一2的另一个侧面和另一个侧面相对的侧面上分别设置有四个间隔相同的刀柄一凹槽21。
进一步，刀柄二3的另一侧面和另一侧面相对的侧面上分别设置有四个间隔相同的刀柄二凹槽31。
进一步，刀柄一凹槽21和刀柄二凹槽31可以提高手握舒适度，也可以使用弹性材料以粘贴等方式固定在刀柄一2和刀柄二3上，在弹性材料上设置刀柄一凹槽21和刀柄二凹槽31，进一步提高使用舒适度。
实施例二：
请参阅图3和图4，本实用新型提供的另一种实施例：一种手持力度均匀的工业用锉刀，本实施例与实施例结构基本相同，唯一不同之处在于刀柄二3的另一侧面接近与锉刀1相连接处设置有突起块32，突起块32上设置有一个刀柄二凹槽31，其作用是，当水平握持锉刀1的两个刀柄时，刀柄二3由于较窄的一端为拇指握持处，所以也会导致两手握持力度不均，突起块32可以让两手用力更均匀。
进一步，还可以在突起块32上固定弹性材料，再在弹性材料上设置刀柄二凹槽31，进一步提高使用舒适度。
工作原理：使用时，双手的四指同时握持刀柄一2和刀柄二3的水平握边，拇指握持倾斜握边，即可令锉刀1水平工作，双手四指同时握持刀柄一2和刀柄二3的倾斜握边，即可令锉刀1与加工工件成一定角度工作，双手握持刀柄一2和刀柄二3时，可以使锉刀1的刀齿11更好的贴合待加工工件，并且提供较好的均匀力度，以提高加工质量。
对于本领域技术人员而言，显然本实用新型不限于上述示范性实施例的细节，而且在不背离本实用新型的精神或基本特征的情况下，能够以其他的具体形式实现本实用新型。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本实用新型的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本实用新型内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
