Slidable limiting jackstay structure

The invention aims to overcome defects existing in the prior art and design a slidable limiting jackstay structure. The slidable limiting jackstay structure comprises a fixed plate, a first support, a second support, a jackstay, a pin shaft, a hinge assembly and a movable cover plate, and is mainly applied to the mechanical structure industry. The problems that in existing jackstay structures, the limiting mode is unfirm, and positioning is failed are efficiently solved. 本发明的目的在于克服现有技术中存在的缺陷，设计种滑动式限位撑杆结构。包括固定板、支座、支座二、撑杆、销轴、铰链总成及活动盖板。该结构主要应用于机械结构行业。高效的解决了现有撑杆结构中，限位形式不牢靠及定位失效的问题。
