[0032] Based on the working principle of the detachable high-temperature protective cover of example one, when the high-temperature protective cover 3 needs to be installed, first, the high-temperature protective cover 3 is wrapped outside the pipeline through the first protective plate 1 and the second protective plate 2, then the first fixed plate 4 and the second fixed plate 15 are driven to move towards each other until the extrusion plate 5 is clamped into the inside of the second square groove 7, at the same time, when the extrusion plate 5 is clamped into the inside of the second square groove 7, the arc-shaped edge of the extrusion plate 5 extrudes the arc-shaped surface of the telescopic block 10, because the telescopic block 10 is connected with the third square groove 8 through the first spring 9, when the extrusion plate 5 extrudes the telescopic block 10, the telescopic block 10 is driven to shrink into the inside of the third square groove 8, and the first spring 9 is also driven to shrink, when the first fixed plate 4 and the second fixed plate 15 are combined together, at this time, the telescopic block 10 moves into the inside of the first square groove 6, when the telescopic block 10 is not extruded by the extrusion plate 5, at this time, the first spring 9 resets, and drives the telescopic block 10 to tightly abut against the inside of the first square groove 6, so as to fix the extrusion plate 5, and fix the first protective plate 1 and the second protective plate 2, which is convenient for quickly installing the high-temperature protective cover 3 outside the pipeline, at the same time, when the first protective plate 1 and the second protective plate 2 need to be disassembled;

[0033] At this time, the pressing rod 16 is pressed in the direction close to the second fixed plate 15, at this time, the third spring 17 is contracted, the pressing rod 16 is pressed, and the end of the pressing rod 16 extrudes the extrusion block 11, after the extrusion block 11 is extruded, the extrusion block 10 moves to the inside of the third square groove 8 and to the outside of the first square groove 6, at this time, the extrusion block 10 no longer abuts against the extrusion plate 5 through the first square groove 6, without disassembling the first protective plate 1 and the second protective plate 2, at this time, the fixed block 21 abuts against the pressing rod 16, so that the pressing rod 16 is difficult to press, avoiding being accidentally touched due to external reasons, causing the first protective plate 1 and the second protective plate 2 to open, when the pressing rod 16 needs to be pressed, the pull rod 20 is pulled away from the pressing rod 16, the fixed block 21 moves to the outside of the pressing rod 16 and no longer abuts against the pressing rod 16, so that the pressing rod 16 can be pressed, after pressing, the pressing rod 16 is released, the third spring 17 is reset, the pressing rod 16 is reset, and the pull rod 20 is released, at this time, the fourth spring 19 is reset, the fixed block 21 is reset, and the pressing rod 16 is reset, so that the first protective plate 1 and the second protective plate 2 are disassembled simply and quickly.
