The invention discloses a reversing mechanism of a lever block. The reversing mechanism comprises a reversing pawl arranged on a handle, and is characterized in that the lower end part of the reversing pawl is provided with an arc-shaped groove, a reversing positioning spring is arranged below the reversing pawl, and the reversing positioning spring comprises a mounting part and a working part; and the mounting part is used for fixing the reversing positioning spring to the handle, the working part is arranged above the mounting part and is used for making contact with the reversing pawl, a bulge is arranged in the middle of the working part and is matched with the arc-shaped groove of the reversing pawl, and the left end and the right end of the bulge contract inwards and are connected with the mounting part. According to the reversing mechanism, the novel reversing positioning spring is designed, the reversing positioning spring has certain elasticity and can position the reversing pawl, the lower portion of the reversing positioning spring is provided with the mounting part and can be conveniently installed on the handle, the working part and the mounting part can be integrally formed, and compared with a traditional reversing mechanism needing components such as an ejector rod, a spring and a spring seat, the reversing mechanism is simple and novel in structure, and can effectively reduces the production cost.

    本发明公开了一种手扳葫芦的换向机构,包括设置于手柄上的换向棘爪,其特征在于:换向棘爪的下端部设有一弧形凹槽,在换向棘爪的下方设置有一换向定位弹簧,换向定位弹簧包括一安装部和一工作部,安装部用以将换向定位弹簧固定于手柄上,工作部设置于安装部的上方,用以与换向棘爪相接触,工作部中间设置有一凸起,凸起与换向棘爪的弧形凹槽相适配,凸起左右两端向内收缩,并与安装部相连接,本发明设计了一种新的换向定位弹簧,换向定位弹簧本身具有一定的弹性,能够对换向棘爪进行定位,换向定位弹簧的下部为安装部,可以方便地将其安装于手柄上,工作部和安装部可以采用一体成形而成,相对于传统换向机构需要顶杆、弹簧、弹簧座等部件,本发明结构简单、新颖,可以有效降低生产成本。
