  • Patent number: 12224633
    Abstract: A auxiliary device for bonding a casing and magnets, comprising a press (10) and a housing positioning seat (2), the press (10) including a press block (12). A vertically arranged raising and lowering rod (3) is provided below the press block (12), the raising and lowering rod (3) being supported on the housing positioning seat (2) by means of an elastic piece. A plurality of push plates (4) are provided on the circumferential side of the raising and lowering rod (3), the push plates (4) being slidingly mated on the housing positioning seat (2) along the radial direction of the raising and lowering rod (3). The raising and lowering rod (3) moves up and down in order to cause the push plates (4) to move in the radial direction of the raising and lowering rod (3), and the sides of the push plates (4) away from the raising and lowering rod (3) are provided with contact faces used to make contact with magnets.

  • Publication number: 20230276916
    Abstract: The present invention discloses a travel case for use as a work table. The travel case is adapted to operate in two modes including a default mode, and a table mode. During default mode, the travel case is configured to function as a conventional travel case and during table mode, the travel case is configured to stand on four legs to use a case body as a horizontal support surface. The table mode is configured to allow for easy access for unpacking and packing the travel case. The travel case comprises a release switch to activate any of the default mode or table mode. The downward movement of the release switch releases the internal mechanism and opens the four legs to a stable stance. The four legs are folded to its initial position to convert the travel case from travel mode to default mode.
