Description

[Brief explanation of the drawing]

Fig. 1 is a side view showing one embodiment of the swinging spring mechanism of the tabletop slide cutting machine according to the present invention;
The figure is a schematic view showing the upper and lower limit positions of the circular saw part, FIG. 3 is an explanatory view of the action of a swing spring, and FIGS. 4 to 6 are side views showing an embodiment of a conventional table-top cutting machine. In the figure, 1 is the base, 3 is the hinge, 4 is the hinge shaft, 5 is the circular saw part, 10 is the spring bar fulcrum, 11 is the spring bar, 12 is the compression spring, 13 is the spring catch part, and 14 is the workpiece. It is a material.

Claims (1)

[Scope of utility model registration request] A workpiece is supported on a base, a front and rear sliding hinge is connected to the rear of the base, and a circular saw part is pivotally supported so as to be able to swing around the hinge shaft above the hinge. In a desktop slide cutting machine that is provided with a swing spring for returning the saw to the upper position and that manually swings the circular saw to cut the workpiece, the saw is swingable on a spring bar fulcrum provided in front of the hinge. An arc-shaped spring bar is provided, one end of the spring bar is passed through a spring hook provided on the circular saw, and an elastic body is attached to the spring bar between the spring bar fulcrum and the spring hook. However, by lowering the circular saw part, the elastic body is compressed and the restoring force increases, but the radius of action of the restoring force of the elastic body on the swinging fulcrum of the circular saw part is reduced, and the circular saw part A swing spring mechanism for a tabletop slide cutting machine that is characterized by reducing swing load changes.
