在钳工装配或机械维修工作中,装配轴同弹性挡圈或孔用弹性挡圈的工作,通常分别是由轴用挡圈钳和孔用挡圈钳来完成的。我们设计了一种两用挡圈钳代替了上述两种钳子,既能上轴用挡圈又能上孔用挡圈。两用挡圈钳的结构如图1所示。它由两支异形的钳柄用销轴穿在一起铆合而成。两柄之间装有扭曲弹簧,使钳口保持初始位 In the fitter assembly or mechanical maintenance work, the assembly axis with the elastic ring or hole elastic ring work, usually by the shaft with the ring pliers and hole with the ring to complete the clamp. We designed a dual retaining ring pliers instead of the two pliers, both on the shaft with the retaining ring can be used on the hole with a ring. The structure of the dual retaining ring pliers as shown in Figure 1. It consists of two shaped handle shank pin with riveted together. Between the two handles is equipped with a twisted spring to keep the jaws in their initial positions
