Since there are inclined surfaces that slide with each other at the bottom end of the compensation block 18 and one end of the inner wall of the cavity 15, when the sliding block 17 moves, the compensation block 18 is squeezed by the inclined surface and moves toward the inside of the sliding block 17, and the compensation spring 19 is compressed. At this time, the combination of the sliding block 17 and the compensation spring 19 is retracted into the cavity 15; when the door frame as a whole enters the door opening, the vertical rod 2 is loosened, and the sliding plate 13 is reset under the push of the avoidance spring 12, so that the connecting block 6 is reset, and the connecting bolt 7 is tightened. The vertical rod 2 is fixed by cooperating with the fixing sleeve 21 and the fixing nut 20, and the reset spring 16 and the compensation spring 19 are extended to push the sliding block 17 and the compensation block 18 to reset, so that the compensation block 18 compensates for the gap between the bottom end of the vertical rod 2 and the cross bar 1, so that there will be no obvious gap in the connection between the vertical rod 2 and the cross bar 1. At the same time, the sealing plug 8 can fill the gap for screwing in the connecting bolt 7, making the door frame more beautiful as a whole.
