Guide groove seats 6 are embedded on both sides of the inner cavity of 1, a steel mesh 2 7 is fixedly connected to the back of the bridge body 2, and a guide block 8 that slides with the guide groove seat 6 is fixedly connected to the bottom of the steel mesh 2 7. The steel mesh 1 4 and the steel mesh 2 7 are staggered up and down, the steel mesh 2 7 is located at the top of the steel mesh 1 4, and the threaded column 5 is located at the top of the steel mesh 2 7. The threaded column 5 is penetrated into the inner cavity of the bridge body 2, and the guide block 8 at the bottom of the steel mesh 2 7 is slid into the inner surface of the guide groove seat 6, and then the nut 9 is rotated, so that the tightening of the nut 9 causes the bridge body 2 to move, thereby driving the steel mesh 2 7 and the steel mesh 1 4 to be staggered, which is also convenient for filling and placing the fire pillow 3. At the same time, the threaded column 5 is located on the inner surface of the sleeve 10, which can avoid the protruding thread of the threaded column 5. The installation spacing is adjusted by rotating the thread, thereby facilitating the purpose of adding fireproof materials. Example 2
