Claims

[Scope of Claim for Utility Model Registration] 1. A press spring for the workpiece is attached to the lower end of the support rod attached downward to the tip of the support arm so as to pass through both left and right sides of the saw blade via a gripping member. In the scroll saw machine, the pressing spring is adjustable in position with respect to the gripping member in the front-rear direction, that is, in the feeding direction of the workpiece, and the intermediate portion of the pressing spring is configured to cover the front of the saw blade by a predetermined width in the vertical direction. A press mechanism for a workpiece in a scroll saw machine characterized by being curved. 2 The pressing spring is formed by a single round wire rod and is curved into a substantially U-shape when viewed from the material feeding direction, and into a horizontal hairpin shape when viewed from the left and right directions, and the upper part of the pressing spring is curved in the material feeding direction with respect to the gripping member. A pressing mechanism for a workpiece in a jig saw machine according to claim 1, which is gripped so as to be able to adjust its position. 3. A press mechanism for a workpiece in a jig saw machine according to claim 1 or 2, wherein the press spring has a bulge that stands up to sandwich the saw blade from both sides. 4. The gripping member is bolted to an upper gripping member fixed to the lower end of the support rod so that its position in the feed direction of the workpiece can be adjusted with respect to the lower surface of the gripping member,
and a lower gripping member having a guide roller for the saw blade, and one end of a pressing spring is clamped and fixed between both gripping members. Pressing mechanism for processed materials.
