A groove engraving device and a groove engraving method are provided. The groove engraving device includes: a processing chamber for containing a piece to be processed, a cutter for groove engraving on the piece to be processed, a clamping mechanism for clamping the piece to be processed, a driving mechanism for driving the clamping mechanism to rotate, and a temperature controlling device for controlling a temperature inside the processing chamber to be within a preset temperature range. The clamping mechanism and the cutter are disposed inside the processing chamber, and the clamping mechanism is rotatable with respect to the processing chamber. The temperature controlling device is disposed inside the processing chamber. The groove engraving device can improve the processing efficiency and quality of the groove engraving on the piece to be processed.

A magnetic bead sorter and magnetic based bead sorting work station. The magnetic bead sorter is configured to receive and store therein one or more beads. The magnetic bead sorter includes a main body having an upper end and a lower end. The main body may be defined by a continuous side wall having a side wall exterior surface and a side wall interior surface. The continuous side wall encircles a magnetic bead sorter inner surface, thus defining an interior region configured to receive and store beads therein.

A collectible card defect correction tool has a cylindrical handle and a ductile, resilient tubing coupled to and extending from a first end of the handle. The handle has a first diameter over a first length. The tubing has an inner diameter. The card tool easily eliminates dents and bends on collectible cards, such as sports cards and gaming cards, making them more presentable and valuable. The handle is comfortable to use, like holding a paint brush.

A geometric art structure includes a half cylinder, a first semi-circular panel, a second semi-circular panel, and a cover. The half cylinder includes a body defining a semi-circular wall having an interior surface, an exterior surface, a first end, a second end, a front end, a closed rear end, and an interior volume. The first end includes a first lateral face. The second end includes a second lateral face. The front end includes a pair of longitudinal faces. The front end includes an opening providing access to the interior volume. The first semi-circular panel is disposed at the first end and extends between the front end and the rear end. The second semi-circular panel is disposed at the second end and extends between the front end and the rear end. The cover extends over the body such that it terminates at the front end, leaving the opening exposed.

A protective device for a processing machine is provided. The protective device includes one end portion including an opening portion, another end portion configured to be detachably attached to a tip end tool holding portion of processing machine, a main body portion extending in a predetermined direction from the other end portion to the one end portion and including a hollow portion communicating with the opening portion, and a spherical member rollably supported by the one end portion and protruding in the predetermined direction from an end surface of the one end portion.

The invention provides a carving knife. The carving knife comprises a knife handle, a blade, a light-emitting structure and a switch structure, wherein the blade is inserted into the front end of the knife handle, the light-emitting structure is mounted on the knife handle and located near the blade, the switch structure is arranged on the knife handle, electrically connected with the light-emitting structure and used for controlling on-off of the light-emitting structure. The carving knife has the advantages of being high in integration level and comfortable in use.
