Claims

[Scope of utility model registration request]

A ratchet wheel is fixed to a rotating shaft to which a crank lever that compresses the closing cam and the closing spring is fixed, and a feed pawl member that meshes with the ratchet wheel and rotates in one direction is swingably provided. A driving force transmission mechanism is connected to the base of the machine via an oil-free bearing, a tension coil spring is provided on the first half of the feed pawl member to bias the feed pawl in a direction in which the feed pawl is constantly in contact with the ratchet wheel, and a cam clutch is provided on the rotating shaft. A closing spring energy storage mechanism characterized by the following.
