Abstract: A linking block includes a top panel, an inner perimeter wall downwardly extended from the middle of the top panel, a bottom panel connected to the bottom edge of the inner perimeter wall, an outer perimeter wall downwardly extended from the outer edge of the top panel and one or multiple holes located in the bottom panel. The invention also provides a method of forming the linking block, which includes a first step of providing a sheet material, a second step of stamping the sheet material into a shape having a top panel, an inner perimeter wall downwardly extended from the middle of the top panel, a bottom panel connected to the bottom edge of the inner perimeter wall and an outer perimeter wall downwardly extended from the outer edge of the top panel, and a third step of creating one or multiple holes in the bottom panel.

Abstract: A nut and support element assembly structure includes: a nut having a screw hole, an end side, and a lateral side; a support element having a bottom resting portion, two end side abutting portions disposed at the end sides of the nut, respectively, and two lateral side clamping portions connected to the end side abutting portions to clamp the nut from the lateral sides. A nut and support element assembly structure includes: a nut having a screw hole, an end side, and a lateral side; a support element having a bottom resting portion, two end side abutting portions disposed at the end sides of the nut, respectively, and two lateral side clamping portions connected to the bottom resting portion to clamp the nut from the lateral sides. A screwing-fixing assembly for use with the nut and support element assembly structure is further provided.

Abstract: A fastening angle bar molding method includes: providing a molding material piece having a through hole; providing a first mold having a protruding portion; providing a second mold having a dented portion which matches the protruding portion of the first mold to form a compressing space; placing the molding material piece between the first mold and the second mold, allowing the first mold and the second mold to engage with each other, pressing the protruding portion and the dented portion against each other to form the fastening angle bar, wherein the fastening angle bar has a first fastening portion, a second fastening portion defining an included angle with respect to the first fastening portion, and at least one angle reinforcing portion connected between the first fastening portion and the second fastening portion. A fastening angle bar is further provided.

Abstract: A manufacturing method for a stage tube that has a first tubular segment and a second tubular segment bordering mutually having different diameters includes: taking a metal plate that has a first segment and a second segment bordering mutually and having a first width and a second width, respectively, the first width being defined between two first paired edges, and the two second width being defined between two second paired edges; forming the first and second segments so as to define a first edge interval; rolling up the first and second segments so that the two first paired edges are jointed together and form the first tubular segment, while the second segment is formed to define a second edge interval; and rolling up the second segment so that the two second paired edges are jointed and form the second tubular segment.

Abstract: A mechanism is composed of a seat, an air or oil cylinder, a connection seat, and a guide rod for maintaining the linear motion of a mechanical arm which is fastened with the connection seat. The guide rod is provided with a slot extending along the direction of the longitudinal axis of the guide rod. Two opposite walls of the slot of the guide rod are provided respectively with a rail enabling the guide rod to move linearly in conjunction with a plurality of rollers engageable with the rails. The axial positions of the rollers can be adjusted to correct the deviated motion of the guide rod.
