The utility model relates to a pressing and unfolding device of a satellite antenna, which does not need an independent locking and releasing mechanism. Comprising the steps that a flexible antenna is arranged on the side face, facing a solar panel, of a satellite body; when the solar panel is in a locked state, the flexible antenna is bent and arranged between the satellite body and the solar panel and is in a compressed state; when the solar panel is unfolded, the flexible antenna is unfolded along with the solar panel, the compressed state is converted into the natural state, the flexible antenna is smoothly unfolded, an additional locking and releasing mechanism is not needed in the whole process, the manufacturing and maintenance cost is reduced, and the risk of task failure caused by complex mechanism faults is reduced.

The application relates to the technical field of clamps, in particular to a fixing device and method for EGR cooler support machining, which comprises a base and an EGR cooler support, further comprises a supporting rod, the side surface of the supporting rod is provided with a lower expansion clamp used for abutting against the lower part of the side surface of the EGR cooler support and an upper expansion clamp used for abutting against the upper part of the side surface of the EGR cooler support, a gas supply mechanism is used for supplying gas to the lower expansion clamp and the upper expansion clamp, so that the lower expansion clamp and the upper expansion clamp are expanded to clamp the EGR cooler support; a sliding base is slidably arranged on the base and used for bearing the supporting rod; a locking mechanism is used for locking the position of the sliding base after the lower expansion clamp and the upper expansion clamp abut against the side surface of the EGR cooler support, the locking mechanism comprises a movable abutting rod arranged in the base and an arc plate arranged in the sliding base and abutting against the abutting rod, a driving assembly is arranged in the sliding base and is driven by the arc plate to provide power for the gas supply mechanism; a rigid adjusting mechanism comprises a double-end plug rod arranged in the supporting rod and an electric push rod used for driving the double-end plug rod to move.
