  • Patent number: 9776238
    Abstract: The magnetic base assembly includes an electromagnet assembly with a top surface open magnetic pole. A shunt plate is magnetically held to the top of the electromagnet. A canting or tilting of the shunt plate results when accidental side or pulling away contact is made between a riveting processing tool and an extending portion of the aircraft part being riveted as the tool is moved from one riveting location to another. The canting or pull off of the tool prevents damage. The operator can observe the tool canting and stop the tool movement or a micro switch or proximity switch senses the canting or tilting automatically so that the tool can be stopped before damage occurs. The magnetic field can be dynamically controlled to provide adequate pulldown force for the riveting function but a breakaway force less than the amount which would cause damage.

    Abstract: A nail guiding structure of the present invention is disposed inside of the nail gun having a nail rail. The nail guiding structure includes one or more supporting members and a holding mechanism. The supporting member can move between a first and a second position, wherein the supporting member can move toward the first position to elastically push nails in the air gun, so that the nails can be vertically held in front of the nail rail. The holding mechanism can selectively hold the supporting member, so that the supporting cannot move back to the second position. Thereby, a user can move the holding mechanism to adapt for different thicknesses of nails. Only one nail can move to the front of the nail rail every time when a punching board of the nail gun punches. Consequently, the problems of nail jamming or crookedly stapling are prevented.

  • Patent number: 8567654
    Abstract: A locking mechanism for a nail gun includes a side slot formed on a bottom side of a gun body and a nail supplying slot connected to a drive track of the nail gun. A stopper element is formed on a side of a slider element corresponding to the side slot. The gun also includes a magazine in which a nail pusher facing the nail supplying slot and a lockout element facing the side slot are formed. The nail pusher has an ear portion. The lockout element includes a pushing arm and a moveable guide slot capping with the ear portion to restrict the sliding movement of the lockout element on the nail pusher. As the pushing arm extends towards the corresponding end of the nail supplying slot, a nail is pushed into the drive track to shoot. The lockout element enters into the side slot to block the stopper element when the nail is exhausted, so as to enhance the shooting blocking effect of the nail gun.

  • Patent number: 8469250
    Abstract: An auto hammer with a striking device includes a striking rod and a clamping mechanism. The striking rod continually strikes a component to gradually insert the component into a workpiece. The clamping mechanism includes at least one clamping element, a biasing device, a bush and a sleeve, and the clamping elements are movable between a closed position and an opened position. The bush is arranged around the striking rod so as to prevent the nail head from becoming trapped in a gap which is formed after the clamping elements are entirely opened. The biasing device is arranged for biasing the bush toward the direction of striking the component. This clamping mechanism can reliably clamp nails or other components to facilitate user operation of the device.
