Abstract

一种电锤用连接杆，包括杆体，所述杆体的前端设置外螺纹段，所述杆体的后端设有钢球槽，所述外螺纹段与钻夹头的前端固定连接。本实用新型提供一种扩充电锤功能、使用方便的电锤用连接杆。

Description

电锤用连接杆
技术领域
本实用新型属于电动工具领域，尤其是一种电锤。
背景技术
电动工具广泛用于建筑工程和室内装修等行业，这种工具要求高效、安全。现国内很多电锤(配方柄建工钻)结构紧凑，但是存在功能单一的缺点。使用过程中想钻有要求尺寸的孔时很不方便，需要更换电钻，很不方便。
发明内容
为了克服的电锤的功能单一、使用不方便的不足，本实用新型提供一种扩充电锤功能、使用方便的电锤用连接杆。
本实用新型解决其技术问题所采用的技术方案是：
一种电锤用连接杆，包括杆体，所述杆体的前端设置外螺纹段，所述杆体的后端设有钢球槽，所述外螺纹段与钻夹头的前端固定连接。
进一步，所述钻夹头的前端安装左旋螺钉，钻夹头前部三爪向内收时中间部可空出装左旋螺钉的空间。
再进一步，所述杆体的后端呈方形，所述方形的四个面上分别开有钢球槽。
本实用新型的技术构思为：在电锤没有单钻功能的情况下扩充电锤功能，通过安装连接杆实现单钻的功能。
参照图2，对于配置方柄建工钻头的情况，采用方柄连接杆3上的四个钢球槽位置很关键，槽位置要保证连接杆头部不与极限位置的冲击杆相干涉。
安装左旋螺钉的目的在于当电锤反转时，不会因旋转方向与螺钉方向一致而松出。如附图2所示，左旋螺钉把钻夹头压在连接杆上。
本实用新型的有益效果主要表现在：扩充电锤功能，减少工作中工具的携带数量，使用方便。
附图说明
图1是电锤用连接杆的分解示意图；
图2是电锤用连接杆的安装示意图。
具体实施方式
下面结合附图对本实用新型作进一步描述。
参照图1、图2，一种电锤用连接杆，包括杆体3，所述杆体3的前端设置外螺纹段，所述杆体3的后端设有钢球槽，所述外螺纹段与钻夹头2的前端固定连接。
所述钻夹头2的前端安装左旋螺钉，钻夹头前部三爪向内收时中间部可空出装左旋螺钉的空间，附图2上说明了此关系，钻夹头前部为空。
所述杆体3的后端呈方形，所述方形的四个面上分别开有钢球槽。该结构针对配置方柄建工钻的场合；当然，也可以选择杆体的后端呈其他形状，例如圆柱形等，圆头的连接杆市场上已有，方头的仅针对国内的方孔电锤。
本实施例的钻夹头上可以安装各类小钻头。

Claims (3)
