This invention provides a badminton racket grip sealing device, including a movable frame. Multiple brackets are fixedly mounted on the side of the movable frame from top to bottom, and these brackets are used to secure the badminton racket. The movable frame is slidably connected to the top of a base, and a traction component is provided on the side of the base. The traction component is used to pull the movable frame to slide on the surface of the base. A limiting plate is fitted to the surface of the base, and a locking screw is threaded onto the side of the limiting plate. A heating component is provided on the side of the base, used to heat and seal the plastic portion of the inserted badminton racket grip. This invention, through its multi-layer bracket design, can simultaneously secure multiple rackets. Combined with the automatic feeding of the movable frame, multiple grips can be fitted with sealing film bags and sealed in a single operation. Furthermore, the limiting plate can limit the movement of the entire movable frame, ensuring a
fixed length of the grip extending into the heating component, resulting in uniform and comprehensive sealing quality and reducing manual intervention.
