The invention provides a needle roller type ratchet wrench, including a handle body. One end of the handle body is provided with a circular handle body hole. The ratchet wrench is provided with a wheel body, the wheel body is in the handle hole, and the center of the upper and lower sides of the wheel body is set with the same type wrench body, and the edge of the wheel body is set with a L type gap, The needle roller movable hole in the L gap and the handle hole wall is gradually reduced, and the needle roller is set in the needle moving hole. The wheel body sets the spring hole at the bottom of the L type gap, and the spring hole is set in the spring hole and the top pin is matched with the needle roller with the needle roller. The needle roller and the roller are at the bottom of the L shape gap. The gap between the two sides of the rolling needle moving hole is provided with a gap, and the rolling needle is tightly clamped by the holes on both sides of the needle moving hole after the rolling needle leaves the bottom of the L shaped notch. The invention has the advantages of simple structure, few parts, rolling needle moving in the L shape notch of the wheel body, and the overall volume of the ratchet wrench is small, which is suitable for more working occasions.
【技术实现步骤摘要】
一种滚针式棘轮扳手
本专利技术涉及一种棘轮扳手。
技术介绍
常用的棘轮扳手采用棘爪开关来实现方向切换,这种结构的扳手其棘爪开关需要有运动空间,因此,造成棘轮扳手的体积相对较大。
技术实现思路
本专利技术所要解决的技术问题是提供一种体积小的滚针式棘轮扳手。为此,本专利技术采用以下技术方案:一种滚针式棘轮扳手,包括柄体,其特征在于所述柄体的一端设置有圆形柄体孔,所述棘轮扳手设置有轮体,所述轮体处在柄体孔中,所述轮体的上侧和下侧的中心分别设置型号相同的扳手体;所述轮体的边部设置L型缺口,所述L型缺口与柄体孔壁组成宽度逐渐减小的滚针活动孔,在滚针活动孔中设置滚针,所述轮体在L型缺口的底部设置弹簧孔,在弹簧孔中设置弹簧以及由弹簧支撑的与滚针配合的顶销,在所述滚针处于L形缺口的底部时,滚针和滚针活动孔的两侧孔壁之间有间隙,在所述滚针离开L形缺口底部后,所述滚针被滚针活动孔的两侧孔壁所卡紧。进一步地,所述轮体沿圆周方向均匀设置多个同向的所述L型缺口,各L型缺口与柄体孔壁组成宽度逐渐减小的滚针活动孔。进一步地,所述柄体孔的底部设置轮体的限位台阶,所述柄体孔的顶部设置卡簧槽,所述轮体的 ...
