The utility model discloses a fast opening and closing movable wrench, which comprises a handle and a plate head at one end of the handle. The plate head is composed of a rigid pliers and a movable pliers head sliding groove. The movable pliers head is installed in the sliding groove of the flexible pliers head. The worm wheel window is provided with a worm wheel, and the clutch holes are arranged on the rigid pliers at both ends of the length direction of the worm wheel window. The bottom of the slide rail groove of the hole self-activating nipper head is opened in the direction of the handle, and a worm wheel axle hole parallel to the slide rail groove of the movable nipper head is arranged on the rigid nipper head. The center line of the worm wheel axle hole intersects the center line of the two clutch holes and is set vertically. A groove extending to both ends and passing through the clutch hole is arranged on the two sides of the wall of the worm wheel window length direction, and the groove mouth is connected with the worm wheel axle hole, and the worm wheel is installed through the worm wheel ax In the worm wheel window, a top spring is arranged in the clutch hole, and a ball is arranged between the top spring and the worm wheel shaft. The movable nipper and the rigid nipper of the utility model can be quickly opened and closed, and the use is convenient, and the work efficiency can be improved.
【技术实现步骤摘要】
快速开合的活动扳手
本技术属于扳手
,具体是涉及一种钳口能快速开合的活动扳手。
技术介绍
活扳手作为一种旋转螺拴、螺钉和螺母用的一种常用工具,广泛应用于机械安装和维修等领域。现有使用的活动扳手主要由手柄、呆钳头、活动钳头和蜗轮组成,钳口的开合通过蜗轮驱动活动钳头来控制。蜗轮与活动钳头一直处于啮合状态,且只能转动,活动钳头与呆钳头组成的钳口不能快速开合,使用不便;当遇到蜗轮与活动钳头发生挤齿时,蜗轮难以松开。
技术实现思路
本技术要解决的技术问题是提供一种活动钳头与呆钳头能快速开合,当遇到蜗轮与活动钳头发生挤齿时,蜗轮也容易松开,使用方便,工作效率高的快速开合的活动扳手。为解决上述技术问题,本技术包括手柄,手柄一端设有板头,板头由呆钳头和活钳头构成,呆钳头上设有活钳头滑轨槽,活钳头安装在活钳头滑轨槽中,呆钳头上设有蜗轮窗,蜗轮窗中设有蜗轮,其结构特点是在蜗轮窗长度方向两端的呆钳头上设有离合孔,所述离合孔自活钳头滑轨槽下底面向手柄方向开设,在呆钳头上设有与活钳头滑轨槽平行的蜗轮轴孔,所述蜗轮轴孔中心线与两离合孔中心线相交且垂直设置,自在蜗轮窗长度方向两侧壁上设有向两端延伸并穿过离合孔的槽口,所述槽口与蜗轮轴孔相通,所述蜗轮通过蜗轮轴安装在蜗轮窗中,在离合孔中设有顶簧,顶簧与蜗轮轴之间设有滚珠,所述槽口及设置在离合孔内的顶簧、滚珠组成蜗轮与活钳头啮合或分离的蜗轮离合装置。所述离合孔的孔口内设有孔盖,所述孔盖底部设有与蜗轮轴滑动相接的润滑炭饼。所述槽口自蜗轮窗长度方向两侧壁面向两端延伸出两离合孔最大外边缘处。所述蜗轮轴的直径小于离合孔的直径。将槽口垂直于两离合孔 ...
