Detonator shell structure

The utility model discloses a primer shell structure, and particularly relates to the technical field of primer, which mainly comprises a primer shell, a sleeving ring plate is fixedly connected inside the primer shell, a primer wire harness is mounted above the sleeving ring plate, and a limit locking component is arranged above the primer wire harness; the limiting and locking assembly comprises a plurality of extrusion linkage hook rods arranged above the detonating wire harness, and the bottom end of each extrusion linkage hook rod extends to the position below the sleeving ring plate and is welded with a linkage supporting column. Through the arrangement of the limiting locking assembly, the linkage screw rod is rotated to drive the threaded sleeving supporting block to move downwards under the action of the interior of the guide frame plate, and the top position of the inner wall of the extrusion linkage hook rod can be extruded to the position above the outer wall of the detonating wire harness; the de
