The utility model discloses a universal cross-section screwdriver, which comprises a handle and a tool handle. The lower end of the tool handle is provided with four inner dialers extending downward. The plane of each inner dialer passes through the vertical axis of the tool handle, and the adjacent inner dialers are perpendicular to each other, and the lower end of the inner dialer is semi-circular. There are 0.5-2 mm between the two inner dialers located in the same plane. The lower part of the tool handle is provided with a sleeve, which can move up and down but can not rotate with respect to the tool handle, and the tool handle is provided with a pressure spring which makes the sleeve have a downward displacement trend; the lower circumference side of the sleeve is fixed with four downward extended outer dials, the lower end of the outer dial is semi-circular, and the four outer dials pass through each other on an average plane. The vertical axis line of the tool handle; the outer part of the sleeve is provided with external threads, and the tool handle is screwed with a nut, which matches the external threads. The utility model has the advantages of strong versatility.
【技术实现步骤摘要】
通用型十字口螺丝刀
本专利技术涉及五金工具
,尤其是涉及一种通用型十字口螺丝刀。
技术介绍
具有十字开口的螺钉的十字开口底部往往不够平整或规格统一。在使用十字口螺丝刀卡入相应的十字开口内旋动螺钉时,螺丝刀的下端刀头并不一定能够十分契合的卡入相应的开口内,从而螺丝刀极易打滑。
技术实现思路
本专利技术的目的是提供一种通用型十字口螺丝刀,它具有通用性较强、不易打滑的特点。本专利技术所采用的技术方案是:通用型十字口螺丝刀,包括手柄以及上部固连该手柄且向下延伸的刀柄,所述刀柄的下端设有4个均向下延伸的内拨片,内拨片各自所在的平面均经过该刀柄的竖向轴心线,相邻的内拨片相互垂直,且内拨片的下端均呈半圆形,位于同一个平面内的2个内拨片之间具有0.5—2mm的间距;所述刀柄的下部套设有套筒,该套筒相对于该刀柄可上下移动但是不可旋转,且该刀柄上套设有使该套筒具有向下位移趋势的压簧;所述套筒的下部的圆周侧面上固定有4个均向下延伸的外拨片,外拨片的下端均呈半圆形,4个外拨片各自所在的平面均经过该刀柄的竖向轴心线;所述套筒的外部设有外螺纹,且该刀柄上螺接有螺帽,该螺帽和该外螺纹相配。本 ...
