Cylindrical anti-drawing spring detection device

The utility model belongs to the technical field of tensile damping springs, in particular to a cylindrical tensile spring detection device, which comprises a sleeve, an upper pull rod is movably inserted into the top end of the sleeve from inside to outside, and the upper pull rod extends to the top of the sleeve and then is fixed on the sleeve through a nut thread. A tensile spring is movably arranged in the sleeve, a sliding plate covering the top of the tensile spring is slidably connected into the sleeve in a sleeved mode, an elastic force adjusting device extending to the bottom of the sleeve is arranged at the axis of the sliding plate, and the elastic force adjusting device comprises an adjusting rod. According to the cylindrical anti-drawing spring detection device, the mechanical induction display device is arranged, hydraulic force can be used for indicating the adjusting rod deviating from the axial lead, inspection personnel do not need to overhaul whether the current stress state of the anti-dra
