Abstract
A stapler has a main base, a pivotal base, a recoiling device, a stapling device, a connecting device and a leg-cutting device. The leg-cutting device is mounted between the main base and the pivotal base and has an upper base, a lower base, two arm holders, two pushing arms, a cutting pad, two cutting blocks, two guiding blocks and two biasing members. The lower base has an arm-lifting top surface. The pushing arms are pivotally connected to the arm holders and each has a sliding end slidably attached to the arm-lifting top surface of the lower base and a pushing end. The cutting blocks are attached respectively to the pushing ends of the pushing arms. The guiding blocks are slidably mounted on the pivotal base and are driven by the cutting blocks.
