  • Patent number: 11364605
    Abstract: A magnetic sleeve includes a body and a magnetic unit disposed in a second section of the body where a locking socket and a mounting hole are formed and communicating with each other. The mounting hole is enclosed by a peripheral wall while taking a reference point as center. The peripheral wall includes at least one engagement surface and at least one curved wall surface. Each engagement surface has two transition points for meeting the wall surface. The formation of one engagement surface or more engagement surfaces not only attains a firm engagement between the magnetic unit and the mounting hole but also forms a space therebetween to discharge air from the mounting hole smoothly, thereby preventing the magnetic unit from being broken during the installation. The space is also minimized to avoid undue accumulation of metal chips and allow the magnetic unit to be held in position stably.

  • Patent number: 11351659
    Abstract: A ratcheting wrench includes a first jaw with a first jaw insert configured to move relative to the first jaw and a first spring configured to bias the first jaw insert in a first direction. The wrench also includes a second jaw with a second jaw insert configured to move relative to the second jaw and a second spring configured to bias the second jaw insert in a second direction opposite the first direction. When the first jaw insert moves relative to the first jaw and the second jaw insert moves relative to the second jaw, a space between the first jaw and the second jaw increases. This allows the jaws of the wrench to slip over corners of a fastener to achieve a ratcheting effect.
