Satellite antenna pressing and unlocking device and using method

The invention provides a satellite antenna pressing and unlocking device and a using method. The device comprises a flexible antenna, a conical spring and a supporting barrel; an antenna main shaft isarranged at the bottom of the flexible antenna; the antenna main shaft sleeves the top end of the conical spring; the bottom end of the conical spring is fixedly mounted in the supporting barrel; a pressing mechanism and an unlocking mechanism which are symmetrically distributed are arranged in the supporting barrel; a first pressing rod and a second pressing rod of the pressing mechanism are connected with a hot melting wire of the unlocking mechanism, so that connection between the pressing mechanism and the unlocking mechanism is achieved; a first locking block and a second locking block of the pressing mechanism are connected with the antenna main shaft in a clamped mode, so that fixed connection between the pressing mechanism and the flexible antenna is achieved. According to the satellite antenna pressing a
