A compressor wheel of a fluid compression device includes a wheel part, a shaft part and a plurality of connection parts. The wheel part includes a main body formed with a through hole, and a plurality of blades protruded from an outer side of the main body. The shaft part is accommodated in the through hole and configured to connect to a rotor shaft. The plurality of connection parts is connected between an inner side of the main body and the shaft part. Wherein, a fluid passage is formed between the inner side of the main body and the shaft part to allow fluid to flow to a rear side of the compressor wheel from a front side of the compressor wheel via the fluid passage.

A floating type machining platform includes a base, a holding platform, a first elastic module, a second elastic module and a third elastic module. The holding platform is configured to hold a workpiece. The first elastic module is connected between the base and the holding platform for allowing the holding platform to move along and rotate around a first axis relative to the base. The second elastic module is connected between the base and the holding platform for allowing the holding platform to move along and rotate around a second axis relative to the base. The third elastic module is connected between the base and the holding platform for allowing the holding platform to move along and rotate around a third axis relative to the base. Wherein, the first and the second axes are different horizontal axes, and the third axis is a vertical axis.

A multi-axis carrying device includes a base, first and second main moving units mounted to the base, a first platform connected to the first and second main moving units, and first and second driving units. The first driving unit has a first output structure coupled to the first main moving unit. The second driving unit has a second output structure coupled to the second main moving unit. When the first and second output structures move in a moving direction, the first and second main moving units are driven to move two opposite sides of the first platform in another direction perpendicular to the moving direction.
