Valve opening and extruding mechanism of micro-fluidic chip

The utility model relates to the technical field of micro-fluidic chips, and provides a valve opening and extruding mechanism of a micro-fluidic chip, which is characterized in that a first extruding shaft is arranged for extruding a first sealing opening and a second sealing opening of the micro-fluidic chip so as to realize valve opening; the second extrusion shaft is used for extruding the reagent in the reagent containing area of the micro-fluidic chip so as to realize extrusion and pushing of the reagent, valve opening and extrusion actions share one driving mechanism and are symmetrically distributed, valve opening and extrusion actions are separated and do not influence each other, the structure is compact, the installation space is saved, and the cost is reduced. And the device can be applied to a limited space of a portable detection instrument. 本实用新型涉及微流控芯片技术领域，提出了一种微流控芯片的开阀及挤压机构，通过设置第一挤压轴用于挤破微流控芯片的第一封口和第二封口以实现开阀，通过设置第二挤压轴用于挤压微流控芯片试剂容纳区内的试剂以实现试剂的挤压推送，开阀及挤压动作共用一个驱动机构，对称分布，使得开阀及挤压分开动作，互不影响，且结构紧凑，节省了安装
