[0019] A shield tail anti-deformation support structure after shelling, comprising a shield tail shell 1 and a support plate 2, the support plate 2 acts on the inner wall of the shield tail shell 1, the outer surface of the support plate 2 is movably connected with a stop block 3, the surface of the support plate 2 is fixedly connected with a connecting frame 4, the surface of the connecting frame 4 is movably connected with a first movable block 5, the surface of the first movable block 5 is fixedly connected with a fixed cylinder 6, the end of the fixed cylinder 6 away from the first movable block 5 is movably connected with a turning handle 7, the inner side of the turning handle 7 is sleeved with an adjusting screw 8, and the end of the adjusting screw 8 away from the turning handle 7 is fixedly connected with a second movable block 9. Through the connection between the shield tail shell 1 and the support plate 2, under the connection between the support plate 2 and the stop block 3, the overall strength of the shield tail shell 1 is supported.

[0020] Furthermore, the support plates 2 are connected to the inside of the shield tail shell 1 in six groups, and the adjacent two groups of support plates 2 are rotatably connected to the stop blocks 3. Through the rotational connection between the support plates 2 and the stop blocks 3, under the action of the support plates 2, the stop block 3 is supported on the shield tail shell 1.

[0021] Furthermore, the stop block 3 is in contact with the inner wall of the shield tail shell 1 through the support plate 2. The stop block 3 is made of rubber. Through the connection between the support plate 2 and the stop block 3, the contact friction between the stop block 3 and the shield tail shell 1 is increased under the action of the stop block 3.

[0022] Furthermore, the first movable block 5 and the second movable block 9 are connected to the adjacent support plate 2 surfaces through the connecting frame 4, and the first movable block 5 and the second movable block 9 are rotatably connected through the connecting frame 4 and the support plate 2.

The adjusting screw 8 and the fixed cylinder 6 act between two adjacent groups of support plates 2 through the second movable block 9 and the first movable block 5.
