A sheet-type flange for transmitting power is formed by a substrate and a multiple of flange sheets. The substrate has a central axle hole with a square key slot and a multiple of fixed holes distributed around the axle hole. The multiple of flange sheets are annular and have connection slots arranged on a periphery of the flange sheets, as well as the multiple of flange sheets are arranged on both sides of the substrate respectively. The substrate and the multiple of flange sheets are fixed together by rivets.

Disclosed is an operating table with multiple degrees of freedom which is capable of moving and rotating in various directions. The operating table comprises an elevating mechanism, a moving mechanism on a horizontal plane and a multiple angle rotation mechanism, with the elevating mechanism and the moving mechanism adopting a leadscrew structure, the multiple angle rotation mechanism comprising a universal joint device (7) and a locking mechanism. The moving mechanism can drive the operating table (6) to move on a horizontal plane and ensure the operating table (6) can reach any location within a valid region on a horizontal plane, the moving mechanisms in the X and Y directions can operate separately as well as cooperatively, and the multiple angle rotation mechanism drives the surface of the operating table to tilt. These mechanisms work in combination to accomplish the location change of the operating table.

A workpiece lateral side clamping tool, in particular a clamping tool that clamps and processes box-type work pieces by means of the lateral sides of the box-type work pieces, comprising: a base board (1), one side thereof being fixedly disposed in intervals with multiple elastic seats (2); each elastic seat (2) is disposed with a vertical V-shaped groove (3); each vertical V-shaped groove (3) is disposed with a rectangular groove (4) at the bottom; each rectangular groove (4) is disposed with a threaded hole (5) at the bottom; a V-shaped pressing block (6) matches inside of the vertical V-shaped groove (3); the V-shaped pressing block (6) forms a through hole (7) that has the same axis as the threaded hole (5) at the bottom of the rectangular groove (4); a bolt goes through the through hole (7) on the V-shaped pressing block (6) and matches with the threaded hole (5) at the bottom of the rectangular groove (4); the base board (1) is disposed in intervals on the side opposite to the elastic seats (2) multiple V-shaped positioning blocks (9); the space between every two neighboring elastic seats (2) corresponds to one V-shaped positioning block (9); the V-shaped positioning block (9) is disposed with a horizontal V-shaped groove (10) that faces the space between the two neighboring elastic seats (2). The tool enhances clamping efficiency.

A punching sheet-type flange formed by overlapping and fixing punching sheet-structure assemblies, comprising a substrate (2) and multiple flange sheets (1) fixed with the substrate (2). The substrate (2) and the flange sheets (1) are of a punching sheet structure. The flange sheets (1) are annular, and connection slots (4) are arranged on the periphery of the flange sheets (1). The flange sheets (1) are arranged on both sides of the substrate. The substrate (2) combines with the flange sheets (1) to form the flange. The substrate (2) and the flange sheets (1) are formed by punching processing. The number of the flange sheets (1) is adjustable. The flange sheets (1) having the complex structure can be processed, thereby accommodating connecting parts of different structures. Connection slots (4) enable convenient assembling and replacement. The flange solves the difficulty in die casting of flanges having complex structures, and solves the problem of flange thickness being not adjustable.
