Clamping tool for checking safety valve

The clamping tool comprises a bottom plate, a top plate, supporting rods, a screw rod and a magnetic base, the bottom plate and the top plate are vertically arranged in parallel at intervals, the supporting rods are vertically arranged between the bottom plate and the top plate at intervals and located on the peripheries of the bottom plate and the top plate, a screw hole is formed in the middle of the top plate, and the screw rod is screwed in the screw hole of the top plate. And the bottom end is movably connected with a magnetic base. The clamping tool overcomes the defects of traditional safety valve verification operation, achieves effective connection between verification equipment and the valve rod of the safety valve, effectively loads external force to the safety valve to be verified, rapidly completes verification of the safety valve, is easy and convenient to operate, saves verification cost, and improves verification operation efficiency. 本实用新型公开了一种用于安全阀校验的夹持工装，本夹持工装包括底板、顶板、支撑杆、螺杆和磁力座，底板和顶板上下平行间隔布
