  • Patent number: 10213914
    Abstract: A blow molding toolbox has a casing, a cover, and multiple reinforcing elements. The casing has multiple connecting recesses, multiple guiding slots, and multiple positioning recesses. The connecting recesses are deposited on an external surface of the casing at corners of the casing. The cover is pivotally connected to the casing and has a same structure as the casing. Each one of the reinforcing elements is connected to the casing at one of the corners of the casing to cover a corresponding connecting recess of the casing or is connected to the cover at one of the corners of the cover to cover a corresponding connecting recess of the cover, and each reinforcing element has a body, at least one fixing tube, and at least one tapping screw. The reinforcing elements may increase the structural strength of the blow molding toolbox.

  • Patent number: 9821449
    Abstract: A file handle has a body, a ferrule, a clamping assembly, and a cap. The body has a first end and a second end opposite to the first end. The ferrule is assembled at the first assembling end of the body. The clamping assembly is movably mounted in the body and has two clamping portions and a threaded hole. The two clamping portions extend through the ferrule. The two clamping portions are subjected to an elastic force and oppositely separated from each other. The threaded hole is adjacent to the second assembling end of the body. The cap is rotatably assembled at the second assembling end of the body and has a screwing stick screwed in the threaded hole. Because the space between the two clamping portions can be adjusted by turning the cap, a user can clamp a tang of a file blade by the file handle.

  • Publication number: 20170072554
    Abstract: A screwdriver has a handle, a cap, a shaft, and multiple screw bits; wherein the handle has two ends. The cap and the shaft are respectively disposed at the two ends of the handle. The multiple screw bits are received inside the handle. The handle has multiple chambers to contain the screw bits that differ in specifications. The handle has multiple first positioning structures. The cap has multiple second positioning structures complementary to the first positioning structures. Because the first positioning structures and the second positioning structures are engaged with each other, the cap cannot be rotated inadvertently, thereby preventing the screw bits dropping out from the handle inadvertently.
