Claims

[Scope of utility model registration request]

(1) An L-shaped lever with a swinging fulcrum near the connecting part between the pin part protruding on the tip support seat of the main body and the force point part connected to the lower end, and the L-shaped lever that engages with the force point part of the lever and rotates in the uniaxial direction. The tool is equipped with a tightening shaft that swings a lever when the lever is moved, and the swinging of the lever presses the throw-away tip inserted into the center hole into contact with the upright surface along the side of the support seat. Inside the main body, there is provided a rond which is biased forward with a spring and which taper engages with the tightening shaft and moves the shaft in the tightening direction when moving forward, and furthermore, a lever is attached to the rond from one side of the main body. A thrower weight cutting tool characterized by having a rotary shaft inserted through the shaft at right angles, and an eccentric cam that rotates integrally with the shaft engaged with the inner surface of the shaft hole of the rod.

(2) The throw according to claim l(1) of the utility model registration, characterized in that the tightening shaft is biased in the loosening direction by a second spring having a weaker force than the spring supported by the main body. Away bite.

(3) Claims (1) or (2) of the utility model registration claim, characterized in that means for preventing loosening of the rotating shaft is provided between the lever portion of the lever-equipped rotating shaft and the main body. Throwaway bite.

(4) One end of the spring that biases the rond is supported by a load adjustment screw screwed into the main body, as claimed in any one of claims (1) to (3) of the utility model registration claim. Throwaway bite described in.
