Abstract

本实用新型的名称为一种膨胀螺丝套管,涉及一种膨胀螺丝套管。为使膨胀螺丝套管工艺更简单,膨胀螺丝使用后能方便的取出,本实用新型套管由两个独立的半圆铁管组成。

Description

一种膨胀螺丝套管
所属技术领域:本实用新型涉及一种膨胀螺丝套管。
背景技术:目前,膨胀螺丝套管由一个整圆铁管组成,成本大,使用后取出困难,又需在底部锯槽,因此工艺比较繁琐,需要改进。
发明内容:为解决上述问题,本实用新型膨胀螺丝套管由两个独立的半圆铁管组成。制造该种半圆铁管的铁板利用率高,制作方便,使用后可轻松的取出整个膨胀螺丝,有利于膨胀螺丝的重复使用和环境清洁。使用这种套管的膨胀螺丝膨胀力不受影响,实验证明膨胀力更均匀,膨胀螺丝更牢固。
附图说明:附图是该种膨胀螺丝套管示意图,图中1为两个半圆铁管,合起后即可使用。
具体实施方式:如附图中1所示,用铁板制成两个半圆铁管,合起后即可使用。这种膨胀螺丝套管制作工艺简单,成本较低,使用后可方便的取出整个膨胀螺丝,有利于材料的重复利用和环境的整洁。
