Description

螺丝刀
技术领域
本发明涉及一种螺丝刀，特别涉及一种可拆卸的螺丝刀。
背景技术
在组装或拆卸螺丝的过程中，一般采用螺丝刀进行拆卸及组装。螺丝刀的种类较多，其有L型螺丝刀及T型螺丝刀。L型螺丝刀包括长臂及由长臂的一端垂直弯折延伸的短臂。由于短臂的长度小于长臂的长度，当通过长臂进行拆卸及组装时，使用者难以通过短臂施加较大力，导致操作不方便。T型螺丝刀包括一体成型的手柄及螺丝刀杆，手柄由塑胶材质制成。由于手柄与螺丝刀杆的接触面积较小，且手柄材质的脆性较大，导致在拆卸及组装过程中塑胶手柄易被碎裂。还有一些T型螺丝刀的手柄由高韧性材质制成，以防止手柄碎裂。然而，在装卸过程中螺丝刀杆易被磨损或折断，需更换螺丝刀杆。由于手柄与螺丝刀杆一体成型，当螺丝刀杆磨损或折断时，即使手柄还可以继续使用也要废弃，且要更换新的螺丝刀，导致螺丝刀杆拆换不方便。
发明内容
鉴于上述情况，有必要提供一种操作方便，且螺丝刀杆的拆换方便的螺丝刀。
一种螺丝刀，其包括手柄及螺丝刀杆，该螺丝刀杆包括长臂及由该长臂的一端垂直弯折延伸形成的短臂。该手柄上开设有相连通的定位槽及穿设孔，该螺丝刀杆的长臂经该穿设孔部分地突出于该定位件外，该短臂固定卡入于该定位槽内。
本发明的螺丝刀采用的手柄上开设有相连通的定位槽及穿设孔，螺丝刀杆的短臂收容于定位槽内，且长臂的一端经穿设孔突出于手柄外，由于螺丝刀杆上安装有手柄，以使方便对螺丝刀杆施加较大力量，从而操作方便。另外螺丝刀杆能够可从手柄上拆卸下来，以使能够快速地更换螺丝刀杆，且手柄可再利用，无需更换新的螺丝刀，以使螺丝刀杆的拆换方便。

具体实施方式
请参阅图1，本发明第一实施方式的螺丝刀100用于拆卸及组装工件(图未示)。螺丝刀100大致呈T形，其包括手柄10及螺丝刀杆30。
请同时参阅图2及图3，手柄10大致呈圆柱状，其包括定位件11、固定件13及两个紧固件15。定位件11大致呈圆柱状，其一侧上凹设有收容部112。收容部112上沿其长度方向开设有定位槽1121。收容部112上贯通定位槽1121开设有穿设孔1122。穿设孔1122与定位槽1121共同形成一个收容空间1120，收容空间1120用以收容螺丝刀杆30。本实施方式中，收容空间1120为L型结构或T型结构。收容部112上靠近定位槽1121的位置处凹设有两个固定槽1123，两个固定槽1123分别位于定位槽1121的两侧。
固定件13与定位件11的收容部112相配合，固定件13安装于收容部112上，且固定件13位于定位槽1121及两个固定槽1123的上方。固定件13上对应两个固定槽1123的位置处贯通开设有固定孔131，固定孔131与对应的固定槽1123相对应。本实施方式中，定位件11及固定件13分别由不易碎裂的材质制成，例如金属，高韧性塑胶等材质制成。
两个紧固件15分别穿设两个固定孔131，并分别锁固于两个固定槽1123内，以使固定件13通过紧固件15固定安装于定位件11的收容部112上。本实施方式中，紧固件15为螺丝。
请同时参阅图4，螺丝刀杆30大致呈L形，其固定安装于定位件11的定位槽1121。螺丝刀杆30包括长臂31及由长臂31的一端垂直弯折延伸形成的短臂33。本实施方式中，螺丝刀杆30为L型螺丝刀杆，且短臂33的长度小于长臂31的长度。长臂31远离短臂33的一端经定位件11的穿设孔1122部分突出于定位件11外。螺丝刀杆30的短臂33收容于定位槽1121内。固定件13通过紧固件15固定安装于收容部112上，且固定件13的底面与短臂33相抵持，以使短臂33夹持于固定件13及收容部112之间。可以理解，当定位槽1121为T型结构时，对应的螺丝刀杆30为T型螺丝刀杆。可以理解，根据螺丝刀杆30结构对应设计定位槽1121即可。
当需更换螺丝刀杆30时，首先，拆卸两个紧固件15；然后，从定位件11的收容部112上拆卸固定件13；接着，拉出螺丝刀杆30；再接着，将新的螺丝刀杆30安装于定位件11的定位槽1121内；固定件13安装于定位件11的收容部112上；最后，紧固件15锁固定位件11及固定件13。
本发明的螺丝刀100采用的手柄10包括定位件11、固定件13及紧固件15，定位件11及固定件13均由不易碎裂的材质制成，以使手柄10不易碎裂。定位件11的收容部112上开设有定位槽1121，螺丝刀杆30的短臂33收容于定位槽1121内，且长臂31远离短臂33的一端突出定位槽1121，固定件13通过紧固件15固定安装于定位件11的收容部112上，且固定件13的底面与短臂33相抵持，以使短臂33通过固定件13固定安装于定位件11上。由于螺丝刀杆30上安装有手柄10，以使方便对螺丝刀杆30施加较大力量，从而操作方便。另外，螺丝刀杆30能够从螺丝刀100的手柄10上拆卸下来，以使能够快速地更换螺丝刀杆30，且手柄10可再利用，无需更换新的螺丝刀，从而节省了成本，且螺丝刀杆30的拆换方便。
可以理解，紧固件15的数量不限于本实施方式中的两个，也可以是一个或两个以上，且固定孔131及固定槽1123的数量根据紧固件15的数量对应设计即可。可以理解，紧固件15可以省略，固定件13固定安装于定位件11的收容部112上，并与螺丝刀杆30的短臂33相抵持，以使螺丝刀杆30的短臂33夹设于定位件11及固定件13之间。可以理解，紧固件15及固定件13可以省略，螺丝刀杆30的短臂33固定卡入于定位槽1121即可。
请同时参阅图5，本发明的第二实施方式的螺丝刀200与第一实施方式中的螺丝刀100大致相同，螺丝刀200也包括手柄50及螺丝刀杆70。不同之处在于，手柄50包括定位件51及固定件53。定位件51的一端上沿其长度方向依次开设有相连通的穿设孔511及定位槽513。穿设孔511靠近手柄50的一端设置，穿设孔511及定位槽513共同形成一个收容空间(图未示)，收容空间用以收容螺丝刀杆70。本实施方式中，收容空间为L型结构。固定件53固定卡入于定位件51的穿设孔511内，并与螺丝刀杆70相抵持。本实施方式中，手柄50由不易碎裂的材质制成，例如金属，高韧性塑胶等材质制成。
螺丝刀杆70包括长臂71及由长臂71的一端垂直弯折延伸形成的短臂73。螺丝刀杆70的长臂71经穿设孔511部分地突出于手柄50外，且固定件53相抵持，以使螺丝刀杆70的长臂71夹设于定位件51及固定件53之间。短臂73固定卡入于定位槽513内。
可以理解，固定件53可以省略，螺丝刀杆70的短臂73固定卡入于定位槽513即可。
另外，本领域技术人员还可在本发明精神内做其它变化，当然，这些依据本发明精神所做的变化，都应包含在本发明所要求保护的范围内。
