Patent ID: 6981627

Claim:
An electric stapler comprising: a frame; a transmission device mounted on the frame; an actuating device connected to the transmission device; a clinching mechanism mounted on the frame and having a driving mechanism to drive a staple with two legs to fasten objects together; and an anvil device mounted on the frame to bend the legs of the driven staple and the anvil device comprising a cover having a through hole for receiving the legs of the driven staple; a stationary frame mounted on the frame and having an arm slot aligned with the through hole in the cover; a sliding anvil mechanism mounted in the stationary frame and comprising a first anvil device and a second anvil device to bend the legs protruding through the through hole, each of the first and the second anvil devices comprising a sliding anvil to bend a respective one of the legs in the through hole, a linkage device connected to the sliding anvil to slide the connected sliding anvil toward the through hole, a pivot swing arm pivotally mounted in the stationary frame to drive the linkage device and having a free end extending across the arm slot, and multiple restitution springs mounted on the stationary frame and connecting to the linkage device; and an anvil driving device mounted on the frame and having a driving arm extending into the arm slot under the free end of each of pivot swing arms; whereby the free end of each pivot swing arm in the arm slot is pivoted upward by the driving arm as the driving arm moves upward, each pivoted pivot swing arm pushes the adjacent linkage device to slide the connected sliding anvil toward the through hole.
