Pulley 2 6 is fixed on both slide bars 5. A fixing plate 7 is fixed in the middle of the two slide bars 5. When the semiconductor detector is installed in the sheet metal cabinet, the fixing plate 7 can be pulled out. At this time, the pulley 1 4 and the pulley 2 6 fixed on the slideway 3 and the slide bar 5 will rotate in the slideway 3, so that the fixing plate 7 can slide out smoothly, and the support rope 8 provides support for the fixing plate 7. The semiconductor detector is installed on the fixing plate 7. When replacement and maintenance are required, the fixing plate 7 can be pulled out.

When the threaded block 206 moves, the limit block 207 fixed on it will prevent it from rotating. At the same time, the two clamping plates 208 fixed thereunder will also move in opposite directions, thereby achieving the effect of clamping a smaller semiconductor.
