Disassembling tool used for thrust segment buckling cover

The invention discloses a disassembling tool used for a thrust segment buckling cover. The disassembling tool comprises a main rod (1) and a sliding impact part (4); the main rod (1) is provided with a connecting part (2) and a stress part (5); the sliding impact part (4) is mounted on the main rod (1) in a sliding manner and located between the connecting part (2) and the stress part (5); through sliding of the sliding impact part (4), the stress part (5) can be impacted to exert axial effect force to the stress part (5), and therefore disassembling tension force can be exerted to the buckling cover connected with the connecting part (2). The connecting part is stably connected with the thrust segment buckling cover, the impact part slides to impact the stress part so as to transmit axial tension to the buckling cover, and the buckling cover is pulled to be gradually separated from a thrust segment; therefore, uniform tension is applied to the buckling cover, and under the condition that the buckling cover is not damaged basically, the buckling cover is disassembled from the thrust segment.
