Abstract: A spare magazine is adapted to be installed in a stapler, and includes a casing unit, a pivot member and a sliding carrier. The pivot member is pivotally disposed in the casing unit, and has a positioning pin. The sliding carrier has a carrier body slidably received in the casing unit, and a main track portion protruding from the carrier body, and having an island block and a surrounding wall that cooperatively define a main track. The sliding carrier is slidable relative to the casing unit between a closed position and a first open position. The positioning pin of the pivot member is inserted into the main track and is slidable in the main track along a heart-shaped route during the sliding movement of the sliding carrier.

Abstract: A stapler includes an elongated channel body pivotably attached to a base, and an elongated magazine track coaxially disposed in and movable relative to a channel of the channel body in a front-and-rear direction between first and second positions. One of the channel body and the magazine track has a bottom wall on which a resilient damping member is disposed, while the other one thereof has a bottom wall which is formed with a frictionless segment, a friction-increasing segment and a stop segment. A friction end of the damping member is disposed at the frictionless segment in the first position, and is slidably moved on and frictionally engaged with the friction-increasing segment and stopped on the stop segment in the second position.
