Abstract
The utility model discloses a bone nail beating and pulling device which comprises a core shaft and a shaft sleeve, a movable buckle is hinged to the front end of the core shaft, the shaft sleeve is arranged outside the core shaft in a sleeved mode in the axial direction of the core shaft, and the shaft sleeve abuts against the movable buckle. When the shaft sleeve moves in the axial direction of the mandrel, the movable buckle is opened or closed relative to the front end of the mandrel. According to the driving and pulling device structure composed of the mandrel, the movable buckle, the shaft sleeve and the handle, a user holds the handle by hand, the movable buckle can be closed and opened by pushing the shaft sleeve to move back and forth, and therefore clamping and releasing of a bone nail are achieved, and when the bone nail is clamped, the bone nail and the front end of the driving and pulling device form a whole; a user obtains a larger and stable grabbing area through the handle, it can be guaranteed that a bone nail can be accurately nailed into a target position by knocking the handle, and the operation performance is greatly improved compared with a manual handheld fixing nailing mode.
