[0019] Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of protection of the utility model.

[0020] As Figures 1-4 As shown in the drawing, an auxiliary device for fixing disc buckle support in the axillary angle part of underground station structure, including base 1, the middle part of base 1 upper side is provided with fixed cylinder 2, the inside lower side of fixed cylinder 2 is provided with guide plug 3, guide plug 3 upper side is inserted with connecting rod 4, and the outer thread is set up in the upper side of connecting rod 4, and the upper side of connecting rod 4 is connected with limit piece 5 in screw thread.

[0021] The lower side of the limiting sheet 5 is provided with an adjusting nut 6 sleeved on the upper side of the connecting rod 4, the lower side of the adjusting nut 6 is rotatably connected with a sleeve 7 sleeved on the upper side of the connecting rod 4 through a bearing, the two sides of the connecting rod 4 are provided with a strip-shaped slot 8, the two sides of the sleeve 7 are threadedly connected with fastening bolts 9 corresponding to the strip-shaped slot 8, and the upper side of the fixed cylinder 2 is provided with a limiting assembly on the two sides.

[0022] The limiting assembly comprises a U-shaped block 10 inserted on one side of the upper side of the fixed cylinder 2, one side of the U-shaped block 10 is provided with a limiting block 11, and the other side of the U-shaped block 10 is connected with the upper side of the fixed cylinder 2 through a screw.
