Abstract:
1. A semi-automatic mortising machine, comprising: a support base including two side walls arranged in the X-axis direction, and at least one platform mounted between the two side walls for placing at least one workpiece; a support bar mounted on the support base in parallel with the X-axis direction and having at least one side face formed with a plurality of tenons which are arranged in parallel with the X-axis direction; a guide device mounted between the platform of the support base and the support bar and operated in a manual manner to displace in parallel with the X-axis direction and in parallel with the Y-axis direction according to a profile of the tenons of the support bar; and a working device moved with the guide device, and including a blade extended downward in the Z-axis direction to contact the workpiece, so that the blade can cut mortises and tenons in the workpiece according to the profile and distance of the tenons of the support bar; wherein the support base further includes at least one positioning member including two rotation disks rotatably mounted between the two side walls of the support base, a positioning rod eccentrically mounted between the two rotation disks, and a drive handle mounted on one of the two rotation disks for rotating the rotation disks, so that the positioning rod is selectively moved toward or away from the platform during rotation of the two rotation disks to selectively press the workpiece on the platform or to release the workpiece from the platform.
