[0026] By setting the steel frame 201, it can be welded with the first molybdenum alloy thin plate 4 and the second molybdenum alloy thin plate 5 to ensure the overall stability of the component. By setting the resin strip 202, it can be fixedly installed on the inner wall of the steel frame 201 and cooperate with the steel frame 201 to form a triangular stable structure, which greatly improves the overall stability of the toughness reinforcement component 2.

[0027] By providing the arched connection block 203, the arched structure can be utilized to evenly distribute the impact force transmitted by the first molybdenum alloy sheet 4 to the side support connection points, and the anti-deformation performance is better. By providing the EPDM rubber block 204, it can be connected with the arched connection block 203 and the second molybdenum alloy sheet 5, and the conducted force can be elastically buffered and absorbed, effectively reducing the strength of the conducted force.
