[0029] Connecting groove 24 is set to the end of top plate 21 away from mounting plate 22, the recess opening of C-shaped clamping plate 23 faces top plate 21, one side of C-shaped clamping plate 23 is fixed with rotating shaft 25, the other end of rotating shaft 25 is inserted into connecting groove 24 and is connected with connecting groove 24, the distance and angle between C-shaped clamping plate 23 and top plate 21 are adjusted by the cooperation of rotating shaft 25 and connecting groove 24, so as to facilitate installation and fixation.

[0030] The connecting groove 24 is provided with a rotating groove 28 at the top of one end of the C-shaped clamping plate 23, and the outer end of the clamping groove 26 extends to the middle of the rotating groove 28, and the rotating groove 28 is used to provide a space for the rotation of the rotating shaft 25.

[0031] The connecting groove 24 is provided with a clamping groove 26 symmetrically on both sides, and the top end of the rotating shaft 25 is provided with a clamping shaft 27 matched with the clamping groove 26. The clamping shaft 27 can move or rotate in the clamping groove 26. The clamping shaft 27 is used to rotate the rotating shaft 25 around the clamping shaft 27 after the rotating shaft 25 is completely extended from the connecting groove 24, so as to adjust the angle between the C-shaped clamping plate 23 and the top plate 21.

[0032] The top plate 21 is provided with a pressing hole 4, and the pressing hole 4 is located at the middle of the connecting groove 24 and matched with the clamping block 31.

[0033] The middle of the rotating shaft 25 is provided with a mounting groove 3, and the opening of the mounting groove 3 faces upward. The mounting groove 3 is provided with a clamping block 31, and the clamping block 31 is in a wedge-shaped structure. The wider end of the clamping block 31 faces the C-shaped clamping plate 23. The bottom of the clamping block 31 is connected with the mounting groove 3 through a spring 32.

The end of the top plate 21 away from the mounting plate 22 is provided with a connecting groove 24, and the C-shaped clamping plate 23 is connected with the connecting groove 24 through a rotating shaft 25, so that the C-shaped clamping plate 23 can be flexibly adjusted in angle and distance, which is convenient for installation and fixation. The rotating shaft 25 is provided with a mounting groove 3 in the middle, which contains a clamping block 31 with a wedge structure and is connected with the bottom of the mounting groove 3 through a spring 32. When it is necessary to remove, the clamping block 31 is pressed to make it separate from the pressing hole 4, allowing the rotating shaft 25 to rotate outward, so that the height of the C-shaped clamping plate 23 exceeds the top plate 21, thereby easily removing the I-shaped steel 1 from the T-shaped iron piece 2, without relying on external large equipment to complete the removal work. This not only simplifies the removal process, but also reduces the size of the reserved hole on the building structure, reduces the construction risk, improves the work efficiency and safety.
