Abstract

本实用新型提供一种电动工具，包括：手柄部分和壳体；壳体的前面位置上设置有夹头，夹头可以在工作模式和夹具模式中操作，该电动工具还包括一个驱动装置可以驱动夹头在轴向的第一位置和第二位置之间移动；夹头在第一位置时，电动工具处于工作模式，夹头在第二位置时，电动工具处于夹具模式，使用者无需用手推动夹头即可切换工具头。

Description

电动工具
技术领域
本实用新型涉及一种电动工具，特别地是一种包含有快换夹头的电动工具。
背景技术
电动工具夹头用于可拆卸的夹持工具头，传统的电动工具夹头需要辅助的工具以便夹头能够夹持或松开工具头。近来，工具夹头已经被设计成可以用手推压夹头从而将夹头从工具头上松开，进而使用者可以更换工具头，但是在操作过程中使用者必须用一只手推压夹头，同时要更换夹头，因此操作起来不是很方便。
发明内容
本实用新型的目的在于提供一种包含有快换夹头的电动工具，无需用手推压夹头即可方便更换工具头。
为了实现上述目的，本实用新型的电动工具，包括：手柄部分和壳体；壳体的前面位置上设置有夹头，夹头可以在工作模式和夹具模式中操作，该电动工具还包括一个驱动装置可以驱动所述夹头在轴向的第一位置和第二位置之间移动；夹头在第一位置时，电动工具处于工作模式，夹头在第二位置时，电动工具处于夹具模式。
驱动装置包括拨动件、驱动件以及致动件，拨动件可带动驱动件位移，致动件与夹头相接触，在驱动件的驱动下致动件可以使夹头在轴向的第一位置和第二位置之间移动。
驱动件包括第一杠杆和第二杠杆，第一杠杆与致动件固定连接，第二杠杆一端与拨动件固定连接，第二杠杆另一端与第一杠杆形成的凹槽相接触，第一杠杆可在第二杠杆的带动下绕一支点旋转。
驱动装置还包括一个弹性复位件，可以是一个弹簧。
本实用新型的电动工具可以通过手指拨动上述拨动件即可实现夹头的模式切换，即从工作模式切换至夹具模式，使用者可以很方便的切换工具头。
附图说明
图1为本实用新型的优选实施方式的电动工具处于工作模式的结构示意图；
图2为图1的电动工具处于夹具模式的结构示意图；
具体实施方式
如图1、2所示，本实用新型的电动工具为一个手持式电钻100，包括手柄部分1和壳体2，壳体2的前面位置上设置有夹头3，所述夹头3可以在工作模式和夹具模式中操作，该电钻100还包括一个驱动装置4可以驱动夹头3在第一位置和第二位置之间移动；夹头在第一位置时，电动工具处于工作模式(如图1所示)，所述夹头在第二位置时，电动工具处于夹具模式(如图2所示)。
驱动装置4包括拨动件5、驱动件以及致动件7，拨动件5可带动驱动件位移，致动件7与夹头3相接触，在驱动件的驱动下致动件7可以使夹头3在第一位置和第二位置之间移动.在本实施例中驱动件包含有第一杠杆61和第二杠杆62，第一杠杆61可绕支点9旋转，第一杠杆61与致动件7固定连接，第二杠杆62一端与拨动件5固定连接.第二杠杆62另一端可与第一杠杆61形成的凹槽8相接触.
另还设置有弹簧11作用于第二杠杆62，起到复位回弹的作用。
如图1所示手指在X方向上拨动拨动件5，因第二杠杆62一端与拨动件5固定连接，第二杠杆62也随着一起移动，由于第二杠杆62另一端与第一杠杆61形成的凹槽8相接触并可在凹槽8中滑动，所以在第二杠杆62的带动下第一杠杆61沿Y方向移动并绕支点9旋转，因此与夹头接触的致动件7形成位移，从而驱动夹头3在轴向Z方向上从第一位置向第二位置移动将夹头打开。此时可以更换工作头。松开手指，在弹簧11作用下，驱动装置4回位。由于夹头也有回位功能，在没有致动件7的力的作用下，自动回位完成装卡动作。
本实用新型并不限于上文及附图所揭示的具体方案，还可以有其他的方式。需要说明的是，以上实施例是非限制性的。除了该实施例外，凡本领域技术人员依常识进行的变换均落在本实用新型的保护范围内。
