Abstract: A triaxial motion device includes first, second and third bases, first and second power sources, and a workpiece positioning member. The first power source is disposed on the first base and has a first driving shaft. The second base is connected with the first driving shaft through a cannular rotary shaft in a way that the second base is rotatable about a first axis. The second power source is disposed on the first base and has a second driving shaft penetrating through the cannular rotary shaft. The third base is connected with the second driving shaft in a way that the third base is rotatable about a second axis perpendicular to the first axis. The workpiece positioning member is disposed on the third base and rotatable about a third axis perpendicular to the second axis. Therefore, the triaxial motion device has small volume and performs highly precise motion.

Abstract: A connection module includes a shaft member that can be rotated in place and can be lifted up and down, two wires arranged side by side and spirally wound on the shaft member, and an holder block connected with the bottom end of the shaft member and the bottom end of each wire such that the holder block drives the two wires to expand or to contract along the axial direction of the shaft member or to spiral in the axial direction of the shaft member when the holder block is driven by the shaft member. Thus, the connection module of the present invention can simplify the conventional complicated wiring mode, thereby saving operation space and reducing the risk of line breakage.

Abstract: An external circulation ball screw consisting of a screw shaft, a screw nut, a cover, two reflow members and multiple rolling members is disclosed. The screw nut defines a mounting groove on the outer perimeter and two return holes in the mounting groove. A first half-return channel on a first step in the mounting groove of the screw nut and a second half-return channel in a second step inside the cover constitute a return channel. Alternatively, a third step can be formed in the cover, or the screw nut can be configured to provide a mounting groove and a third step with return holes in the mounting groove. Thus, same size of reflow members can be used with different lengths of return channels.
