摘要

A portable apparatus is provided with an operating head slidably mounted on a guide plate for successively fastening stirrup-links on the end of a conveyor belt via staples. A movable die within the operating head for clinching the staple ends has a first portion located opposite to the staple-inserting punch and provided with grooves for initial clinching of the staple ends. A second portion of the die is provided with grooves for final clinching of the staple ends of the following stirrup-link which have already been subjected to initial clinching. A second punch penetrates into an opening of the staple-guiding plate in order to arrest the operating head in each predetermined position and to serve as an anvil for bearing against the head of each staple at the time of final clinching. The second punch is actuated by a lever which also actuates the stepping-motion ratchet mechanism while another lever controls the operation of the staple-inserting punch and the operation of the die.
