[0035] When the horizontal plate 2041 moves downward, the top protective plate 2043 moves downward and is tightly attached to the top wall of the tank body 101. At the same time, the two plug plates 2044 at the bottom of the horizontal plate 2041 are respectively inserted into the plate grooves 2029 on the two placement seats 2021, so that the extrusion block 2045 generates a thrust on the pressure block 2028, pushing the clamping rod 2026 toward the tank body 101, so that the clamping rod 2026 on the two placement seats 2021 clamps and fixes the side walls of the tank body 101, thereby improving the fixing stability of the hydrogen storage tank body 1. Finally, the bolt 20211 is screwed into the screw groove 20210, so that one end of the bolt 20211 is stuck in the positioning groove 2046 on the plug plate 2044, thereby fixing the horizontal plate 2041.
