  • Patent number: 7866522
    Abstract: Disclosed in a stapling device that is sound, safe, convenient and not easy to get lost and that is applicable to staples of multiple specifications. A casing has a rear end to which an adjustor is set. The adjustor has a fitting portion that is comprised of two or more than two fitting blocks each having an engaging face that is spaced from a central axis of the adjustor by a different distance. A rear end of the casing is provided with a depress-to-fix member corresponding to the adjustor. The depress-to-fix member forms a fitting slot. This arrangement allows selective change engagement between the fitting slot and different fitting blocks thereby changing the set position of a rear guide plate and realizing change of gap size of a staple outlet opening for being applicable to staples of different specifications.

  • Patent number: 7594598
    Abstract: A safety is incorporated in a nailing device, which ensures operation safety of the nailing device. The nailing device includes a housing in which a striker plate is mounted and movable to a ready-to-strike position for subsequently striking a nail out of the housing. The safety includes a retainer pivoted to the housing with an inner end engaging the striker plate to retain the striker plate against movement to the ready-to-strike position and an opposite outer end engaging a release plate that is biased by a spring to partially projecting beyond the housing. When the nailing device is properly set on a work piece, the release plate is forced against the biasing spring back into the housing and the inner end of the retainer is caused to disengage from and thus freeing the striker plate.

  • Patent number: 7571840
    Abstract: A safety is incorporated in a nailing device, which ensures operation safety of the nailing device. The nailing device includes a housing containing a striker plate movable to a ready-to-strike position for subsequently striking a nail. The safety includes a retainer having an inclination engageable with a mated inclination formed on a release plate that is normally biased to partially project out of the housing, so that a stop of the retainer is set at a position to block the striker plate from moving toward the ready-to-striker position. When the nailing device is properly set on a work piece, the release plate is forced by the work piece back into the housing and the retainer is rotated by the camming action between the mated inclination faces so as to move the stop aside to allow the striker plate to move to the ready-to-strike position.
