Patent attributes
A jam-resistant tacker apparatus is invented, comprising a slit for engagement with an upper pin at the upper ends of a plurality of pin guides mounted to a magazine cover and forming a seating recess for receiving the upper pin at a predetermined position of the magazine so that the forward and backward movement range of the pin guides is increased, and by providing a spring having less elasticity than the spring of a pusher at the upper rear ends of the plurality of pin guides so that a tacker pin and the pusher can be guided while remaining in close contact. The present tacker apparatus is able to prevent of the problem of jammed tacker pins, by applying a horizontal elasticity for stably guiding the tacker pin horizontally in addition to an upward elasticity for moving the tacker pin upward.
