  • Publication number: 20180172167
    Abstract: A connector structure of an air connector contains: a body, two Schrader (American) retainers, two Presta (French) retainers, two fixing blocks, a control set, and a movable post. The body includes a Schrader (American) inserting hole, a Presta (French) inserting hole, an accommodation groove, an air intake, two first through orifices, two second through orifices, two receiving orifices, and an airtight washer. The two Schrader (American) retainers move in the two first through orifices. The two Presta (French) retainers move in the two second through orifices. The two fixing blocks move in the two receiving orifices. The control set is disposed on the body and controls a first limiting segment of each Schrader (American) retainer, a second limiting segment of each Presta (French) retainer, and a third limiting segment of each fixing block. The movable post is limited by the Presta (French) inserting hole and the accommodation groove.

  • Publication number: 20170334045
    Abstract: An torque warning structure is adapted for a rotary hand tool, and the rotary hand tool contains at least one rotatable pulling bar, one of the at least one rotatable pulling bar includes a fulcrum portion and at least one forcing portion. The torque warning structure contains at least one resilient element which is solely mounted or is jointly stacked on the at least one forcing portion, and each of the at least one resilient element has a pushing portion and a contacting portion between which a height difference is defined, the contacting portion contacts the at least one forcing portion, wherein the pushing portion drives the rotary hand tool to rotate, and when a pushing force of the pushing portion of said each resilient element is more than a deformation resistance of said each resilient element, said each resilient element deforms and makes warning sound.

  • Patent number: 9511636
    Abstract: A joint structure for an air nozzle contains a valve joint connected on an air nozzle to fill air, with the air nozzle including outer threads defined around an outer peripheral side thereof. The valve joint includes a body having a hole defined therein, an inlet communicating with the hole, and at least one orifice penetrating from an exterior environment to the hole. At least one limiting member is secured and moves in the at least one orifice and has meshing teeth formed on one end thereof to correspond to the hole. The meshing teeth engage with the outer threads of the air nozzle. The at least one limiting member has a defining segment arranged on another end thereof. A controlling assembly is fitted on the body and is used to control the at least one limiting member to move in the at least one orifice.
