A router includes a housing and a motor assembly disposed within the housing. The motor assembly includes a driven shaft having a cavity on a first end of the driven shaft. The router includes a collet that is configured to mate into the cavity of the driven shaft with the collet being configured to grip a shank of a router bit. The router includes a gear mechanism that is configured to couple and decouple from a second end of the driven shaft such that a rotation of the gear mechanism when the gear mechanism is coupled to the second end of the driven shaft causes at least one of tightening and loosening of the collet.

The present invention relates to a woodworking work table and a multipurpose woodworking device including the woodworking work table. The woodworking work table includes: a support post having a predetermined height; a base frame member supported by the support post; a vise member combined with the base frame member to fix a wood piece to be fabricated; a slider disposed under the base frame member and the vise frame member to slide the vise member in a front-rear direction; and a feeding device moving a woodworking machine mounted over the base frame member in X-axial, Y-axial, and Z-axial directions, in which the base frame member has a plurality of first jig-coupling grooves for coupling at least one of a plurality of woodworking jigs, and the vise member has a plurality of second jig-coupling grooves and a plurality of third jig-coupling grooves for coupling at least one of the woodworking jigs.

The present invention provides a jig for fabricating a concave-convex structure. The jig for fabricating a concave-convex structure is coupled to a multipurpose woodworking device including a woodworking work table for performing a plurality of operations for forming a concave-convex structure and a router mounted on the woodworking work table to perform the operations for forming a concave-convex structure, using a plurality of end mills. Furthermore, the jig for fabricating a concave-convex structure includes at least one of a wood piece support jig supporting or fixing a wood piece to be fabricated, a shaping guide jig allowing for forming shapes corresponding to the operations for forming a concave-convex structure, and a stopper jig maintaining X-axial movement of the router by intervals corresponding to the operations for forming a concave-convex structure. Accordingly, it is possible to easily fabricate circular, round, rectangular, dovetailed, and gallery-shaped grooves and joints.

A copy device for processing and shaping a cylindrical rod with a curved configuration includes a seat main body and a plane template. The seat main body is formed with an internal working space. The seat main body further has a reception opening in communication with the working space. A stock can be disposed in the working space and driven to rotate within the working space. The seat main body is arranged on a spindle moulder. A cutting tool of the spindle moulder can enter the working space through the reception opening. The plane template has a copy model. The cutting tool has a mould leaning section for leaning against the copy model, whereby the cutting tool can cut and process the stock to shape the stock with a configuration copied from the copy model.

A router bit that includes a shank end, a boring end opposite to the shank end, a drill axis that is defined between the shank end and the boring end, a shank that extends from the shank end and is adapted to engage with a chuck of a router, and a body that extends from the shank to the boring end and defines a non-linear profile. The router bit also includes a pair of cutting edges of the body that helically extends along the drill axis between the shank and the boring end. The router bit also includes a pair of flutes of the body that is defined between the pair of cutting edges and helically extends along the drill axis between the shank and the boring end. The body is configured to cut a non-linear profile into a work piece.
