具体实施方式
以下结合附图及较佳实施例， 对依据本实用新型提供的具体实施方式、 结构、 特征详述如下：
如图 1-图 3所示，该剪压卡箍钳（见图 1 )包括钳头组件 A和钳柄组件 B。 所述钳头组件 A由钳头销轴 4连接左、 右钳头 1及上下对应设有的两侧 压板 2所构成， 压板 2之间的两钳头 1的中心处设有中心轴 3 (见图 2a ), 且 钳头组件 A通过钳头 1尾孔内的连接销轴 5与钳柄组件 B的左、 右钳柄 14、 15相连； 所述钳柄组件 B是由钳柄 14、 15上部中心设有的钳柄连接轴 6将 左、 右钳柄 14、 15、 钳柄胀簧 7和止退板 9组合连接在一起； 其特征在于所 述由钳头 1、 压板 2和钳头销轴 4构成的钳头组件 A结构中， 上下两侧压板 2 上部内侧呈阶梯状， 所述两侧压板 2上部分别与钳头 1之间形成的间隙构成 让位槽 2-1 (见图 2b )， 其宽度对应所被剪切的管件厚度， 可设定为 > 1.2111111。 所述钳头 1的刃口内侧设有斜面 1-1 (见图 3 ); 所述钳柄组件 B采用连接销 轴 5将钳柄胀簧 7和止退板 9同轴嵌入左钳柄槽内， 即钳柄连接轴 5将左、 右钳柄 14、 15, 钳柄胀簧 7和止退板 9组合连接在一起。
所述右钳柄设置有止退爪 10, 由止退爪销轴 11连接于右钳柄 15内， 止 退爪拉簧 12—端挂在止退爪 10上，另一端通过拉簧柱销 13定位于右钳柄 15 上， 止退爪 10和止退板 9啮合， 在钳柄闭合时防止钳柄回退。
所述左钳柄 14内设置用于调节止退板 9的调节螺钉 8 ,其为偏心轴结构， 中间偏心部位穿于止退板 9孔中， 转动调节螺钉 8， 调节左、 右两钳柄 14、 15的闭合间距； 从而可以对钳口口隙进行调节。
所述左、 右钳柄 14、 15分别套设有增力柄 16、 17。
使用剪压卡箍钳该卡压卡箍时， 完全打开手柄， 将耳式箍箍耳平行于钳 口， 放入钳口内， 闭合手柄， 钳口随之闭合将箍耳逐渐夹紧， 同时， 止退爪 与止退板上的棘齿啮合， 防止手柄回退， 当手柄夹紧到闭合极限时， 卡箍被 夹紧到位， 同时止退爪与止退板脱开啮合， 此时放开手柄， 手柄在钳柄胀簧 作用下张开， 钳头打开， 放开卡箍。 拆卸卡箍时， 完全打开手柄， 将夹后箍 耳重直于钳口放置， 使箍耳一侧紧贴于压板内侧， 让卡箍钳刃口箝住箍耳另 一侧， 闭合手柄， 此时紧贴于压板一侧的箍耳不被剪切， 而进入钳口与压板 间的让位槽内， 而位于钳口间的箍耳另一侧则被剪切， 闭合手柄到闭合极限 位置， 箍耳可被轻松剪开， 放开手柄， 钳口打开。
使用本实用新型， 可快速卡压和剪断轻型、 标准型和加强型耳式卡箍。 本实用新型的主要工作原理： 所述的钳头组件中 , 两侧压板上部内侧采 用让位槽结构， 钳头刃口内侧设有斜面， 钳头通过钳头销轴连接于具有让位 槽的压板之间， 压板之间的两钳头的中心处设有中心轴， 钳头的上部与压板 间形成一个间隙， 即让位空间； 在剪箍时让夹后卡箍垂直钳口放置， 保持箍 耳一侧紧贴压板内侧， 使钳口只剪切箍耳单侧金属， 减小了剪切力从而达到 剪断耳式箍的目的。 上述参照实施例对该剪压卡箍钳进行的详细描述， 是说明性的而不是限 定性的， 可根据需要制成各种不同的规格， 因此在不脱离本实用新型总体构 思下的变化和修改， 应属本实用新型的保护范围之内。
