发明名称 Portable rivet anvil
摘要 A rivet anvil for replacing rivets holding sickles, such as on hay and grass mowers, combines, and other machinery, while in the field, has a base with an upstanding rod. A rivet seat is formed in the top of the rod and is sized to accept and hold a rivet head while its post is peened. The anvil is relatively lightweight and can be carried with the machine.
