Abstract

助力螺丝刀属手工五金工具。它由手柄1、刀杆 2、助力杆3和柄套4组成。手柄1的中心有盲孔5, 上部有通孔6。助力杆3平时存放于盲孔5中,使用 时插入通孔6中,可明显增大手柄的扭矩。单手持握 手柄1和助力杆3工作,既可省力省时地安装与拆卸 螺钉。

Description

本实用新型是一种螺丝刀,属于手工使用的五金工具。
普通民用螺丝刀由于手柄直径所限,使用时不能产生足够大的扭矩,以致在安装木螺钉或拆卸锈蚀的螺钉时,难以顺利完成工作。有些新型螺丝刀(例如实用新型专利申请公告号CN2081782u)虽设法延长了手柄的力臂,可以起到省力的作用,但增加了制造难度和成本;操作时需双手配合动作,也给使用者带来不便。
本实用新型的目的,是提供一种新型的助力螺丝刀。它不但可以灵活地延长手柄的力臂,而且只需单手操作,就能够省时省力地完成螺钉的安装与拆卸。
通过以下方式可以实现本实用新型的目的:
助力螺丝刀由手柄、刀杆、助力杆和柄套组成。手柄的端部有轴向中心盲孔,手柄的上部有径向通孔。助力杆平时存放于盲孔中。柄套复盖在手柄顶部,其作用是固定助力杆。
本实用新型的优点是:在需要加大螺丝刀的扭矩时,取出助力杆,插入通孔中。助力杆在通孔中的位置可以根据需要调节。单手同时持握手柄和助力杆,转动螺丝刀,就可以省力便捷地装、卸螺钉。
以下结合附图对本实用新型作进一步说明。附图为手柄部分剖面图。它主要包括:手柄1、刀杆2、助力杆3、柄套4、盲孔5和通孔6。盲孔5与通孔6的孔径相同。盲孔5的深度小于手柄1的长度。助力杆3的长度略小于盲孔5的深度。其直径略小于盲孔5的孔径。如图所示,助力杆3的顶部直径略大,存放时“卧”入盲孔5中,使手柄1的顶部持平,上面复盖杯形柄套4;插入通孔6中时,又可避免滑脱。助力杆3的尾部为尖锐状,在安装木螺钉时可用于定位。助力杆3的存放为内藏式,不改变螺丝刀的外部尺寸。助力杆3与通孔6的配合稳定牢固,使螺丝刀可承受很大的扭矩。盲孔5及通孔6的孔径不大,不会影响手柄1的使用性能和寿命。
助力螺丝刀制造简单,加工方便。助力杆3宜用金属材料制成,可以用民用铁钉代替。柄套4宜用橡胶、塑胶等具有一定弹性的材料制造,既便于安装使用,又可以增大手柄的摩擦力。
