所述基座的顶部凹槽内设有防尘塞，防止异物进入基座内部，对刀座基座系统起到保护作用。
本发明与现有技术相比，具有如下有益效果：本发明与现有技术相比，具有如下有益效果：
1、针对该产品的实际使用场合和环境因素，刀座基座采用整体封闭式结构，在防尘塞、螺栓橡胶尾盖及橡胶密封圈的作用下，切削磨料灰尘不易进入内部螺纹孔，降低系统故障和损坏机率，且便于日后维修保养。
2、螺栓与防松垫圈的配合使用，相对传统无垫圈易松动的情况，极大的降低了螺栓松动的可能性。
3、刀座采用轻量化的设计，在保证使用寿命和性能的同时，提高了燃油的经济性。
4、刀座和基座固定连接，从而使刀具的切削力更好的通过刀座传递到基座上，且采用曲面与曲面的配合方式，使两者之间的受力面积增大，从传统约4000mm2增大到约4500mm2，刀具切削时的力更好的分散到刀座和基座中，从而优化了刀座基座系统的寿命，并且能承受来自各个方向更强的力的冲击。
5、刀座与基座的的接触面预紧力约为50-55kN，在保证此预紧力的同时，螺栓锁紧扭矩相比传统的约500Nm降低到约250Nm，降低了一倍。这样，即使在没有电力和机械工具的实际使用过程中，操作者仅凭借人力即可达到工作所需扭矩，降低了操作人员的工作难度和强度，增加了其实用性，符合该产品野外作业的特性。
6、此款产品在刀座上设计布置有内螺纹孔，因刀座是损耗件，相比传统在基座上布置内螺纹孔的做法，在内螺纹因工作或其他原因损坏时，不用连同基座一起拆卸替换，仅需替换刀座，不仅大大地降低了维修的难度、强度、成本，更重要的是节约了维修所需的时间，提高了产品的使用效率和经济效益。
本发明的的刀座固定部穿过基座内孔，通过螺栓以及防松垫圈，与刀座固定部的内螺纹锁紧，从而将刀座和基座固定连接，从而使刀具的切削应力更好的通过刀座传递到基座上，刀座将力传递给基座；且采用曲面配曲面配合方式使两者之间的受力面积增大，刀具切削时的力更好的分散到刀座与基座中，从而优化了刀座基座系统的寿命，刀座和基座通过不同的曲面支撑连接，相比于现有技术中基座呈一个整体的球面设计，能承受来自各个方向更强的力的冲击，本发明的刀座在做到更轻量化的同时，提高了本身的使用性能。
