The invention discloses a jack rocker limiting mechanism. The jack rocker limiting mechanism comprises a jack body. The right side of the jack body is fixedly connected with a rocker arm. A user inserts a rocker into the rocker arm and rotates a rotary rod to drive a cam to rotate. The cam is in rotary fit with a groove to drive a ring frame to move leftwards. The ring frame moves leftwards to drive sliding columns to move leftwards. The sliding columns are matched with sliding grooves to move leftwards in a limited mode, meanwhile, the ring frame drives a rubber plate to move leftwards, finally, the rubber plate moves leftwards to compress a spring to reduce vibration and enable a fixed rod to be fixed to the interior of a clamping groove through an opening to complete fixing, and vice versa, fixing is released. Through the jack rocker limiting mechanism, the problem that an existing jack rocker does not have the fixing function and is likely to fall off in the motion process is solved. The operation safety of a user is improved, the operation comfort of a jack is improved, and the practicality of the jack is improved.
本发明公开了一种千斤顶摇杆的限位机构,包括千斤顶本体,千斤顶本体的右侧固定连接有摇臂,千斤顶本体的右侧固定连接有摇臂。本发明通过使用者插入摇杆在摇臂的内部,然后旋转转杆,转杆旋转带动凸轮旋转,凸轮旋转配合凹槽使环形框向左移动,环形框向左移动带动滑柱向左移动,滑柱配合滑槽向左限位移动的同时环形框带动橡胶板向左移动,最后橡胶板向左移动压缩弹簧减震的同时使固定杆通过开口固定在卡槽的内部完成固定,同理反之解除固定,解决了现有的千斤顶摇杆不具有固定功能,导致活动过程中容易脱落的问题,增加了使用者操作过程中的安全性,也增加千斤顶操作的舒适性,也提高了千斤顶的实用性。
