Detonator shell bending resistance testing device

The utility model relates to the technical field of detonator shell bending resistance testing, and discloses a detonator shell bending resistance testing device which comprises an operation table, the top surface of the operation table is fixedly connected with a U-shaped support, a testing device is arranged above the operation table, and the testing device comprises an extrusion part. According to the detonator shell bending resistance testing device, a hydraulic thrust rod, a rotating shaft, a worm gear, a worm, a gear, a rack, a pressing block, a T-shaped sliding plate and a mounting plate are arranged to control the hydraulic thrust rod to extend, so that the pressing block downwards extrudes a detonator shell, and the bending resistance of the detonator shell is conveniently tested; the relative position of the pressing block to the detonator is changed, so that different areas on the pressing block extrude the detonator shell, the bending resistance of the detonator shell under different pressing area
