[0024] Working principle: when the first threaded rod 13 is rotated, the first lug 6 on both sides is driven to move close to or away from the first moving groove 5, thereby adjusting the position of the left and right fixed blocks 7 until the width of the profile to be processed is matched, and the left and right positions of the profile to be processed at the fixed box 4 are controlled, the second threaded rod 11 is rotated, the second lug 9 is driven to slide up and down along the second moving groove 8, and the parallel plate 10 is at a suitable height, so that the profile is placed, the parallel plate 10 can completely support the bottom of the profile, and the installation height of the profile to be processed is adjusted.
