Abstract

本发明公开了一种家装钻孔用钻头，包括钻头本体，所述钻头本体的表面且沿着周向间隔分布有多个翼刀体，所述翼刀体由下到上分为三段，第二段直径尺寸大于第一段的直径尺寸，第三段的直径尺寸大于第二段的直径尺寸，第三段直径尺寸等于钻孔直径。由于采用上述的结构形式，有效地保护墙壁不被破坏。

Description

家装钻孔用钻头
技术领域
本发明涉及一种家装钻孔器具，具体是一种家装钻孔用钻头。
背景技术
现有的家装钻孔用钻头在钻孔过程中，容易破坏墙壁。
发明内容
本发明的目的在于提出一种有效地保护墙壁不被破坏的家装钻孔用钻头。
本发明采用的技术方案如下：
家装钻孔用钻头，包括钻头本体，所述钻头本体的表面且沿着周向间隔分布有多个翼刀体，所述翼刀体由下到上分为三段，第二段直径尺寸大于第一段的直径尺寸，第三段的直径尺寸大于第二段的直径尺寸，第三段直径尺寸等于钻孔直径。
进一步地，所述翼刀体上分布有多个切削齿。
本发明的有益效果：由于采用上述的结构形式，有效地保护墙壁不被破坏。
附图说明
图1为本发明的结构示意图。
图中：1、钻头本体；2、翼刀体；3、第一段；4、第二段；5、第三段；6、切削齿。
具体实施方式
如图1所示，家装钻孔用钻头，包括钻头本体1，所述钻头本体1的表面且沿着周向间隔分布有多个翼刀体2，所述翼刀体2由下到上分为三段，第二段4直径尺寸大于第一段3的直径尺寸，第三段5的直径尺寸大于第二段的直径尺寸，第三段5直径尺寸等于扩眼直径，即井眼实际尺寸；所述翼刀体2上由下到上分布有多个切削齿6。由于采用上述的结构形式，有效地保护墙壁不被破坏。
以上所述是本发明的优选实施方式而已，当然不能以此来限定本发明之权利范围，应当指出，对于本技术领域的普通技术人员来说，对本发明的技术方案进行修改或者等同替换，都不脱离本发明技术方案的保护范围。
