Claims

[Scope of utility model registration request]

a frame rotatably supported in a horizontal plane by a support shaft; a rotating arm attached to the frame near the center line of the support shaft by a shaft pin so as to be rotatable in a vertical plane;
A needle bar is attached to the rotating arm so as to be movable in the axial direction of the rotating arm, and is configured to be rotatable in a vertical plane including the center line of the support shaft, and the needle bar is attached to the rotating arm so as to be movable in the axial direction of the rotating arm. It has an arm equipped with a crank mechanism for a needle bar that moves it up and down, and a crank mechanism for a rotating arm that rotates and holds the rotating arm at a free angle in the left and right direction together with the needle bar about an axis pin as a fulcrum, The rotating arm crank mechanism has a grooved cam that is rotated in synchronization with the needle bar crank mechanism, and a protrusion at the tip of the grooved cam is fitted into the cam groove of the grooved cam, and the rotating arm is pivoted on a bearing of the frame. A rotating arm whose plate end is fixed to a shaft, a swinging arm fixed to the tip of the swinging shaft, and a movable piece movably fitted into a guide groove of the swinging arm. , one end of the movable piece is fitted onto the small shaft of the movable piece, the other end is fixed to the rotating arm by a set screw, and is driven by a motor and a connecting arm that connects the rotating arm to the movable piece. and a moving member for moving and stopping the movable piece at an arbitrary position in the guide groove.
