Title:
GRINDER DISK RETAINING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/153705
Kind Code:
A1
Abstract:
A disk retaining holder can be conveniently retained on a disk retaining device by one touch. In addition, it is possible to prevent a disk retained by the disk retaining holder from being shaken by strong vibrations acting on the grinder during a marble grinding operation. Accordingly, an accurate and safe grinding operation can be performed. The disk retaining holder is prevented from being unfastened from the disk retaining device because, if the disk gets stuck in a cutting workpiece, same cannot maintain the position with a restorative force from a spring. The disk retaining device is simplified to have a slim structure such that a commercially available disk can be interchangeably used with the grinder. According to the present invention, the grinder disk retaining device has a simple configuration such that same can be manufactured in a simplified manner. The assembly structure is conducted in a stepwise manner, thereby providing assembly ease. The rotating shaft of the grinder fastened to the rotating fastener of the disk retaining device is exposed to the upper portion of the disk retaining device such that not only a dedicated disk, but also a universal disk can be used interchangeably. The disk can be conveniently retained by one touch. In addition, it is possible to prevent the grinding disk from being shaken by strong vibrations acting on the grinder during a marble grinding operation, for example. Accordingly, the surface of the processing target can be ground and cut accurately. Thus, the rotational balance can be improved, thereby increasing the lifespan and improving the cutting performance, and a precise operation can proceed safely.
