A limiting fixing component is provided on the outer side of the top of the T-shaped guide strip 6. A T-shaped plug-in groove 7 corresponding to the bottom end size of the T-shaped movable groove 5 is provided on both sides of the lower shear wall 1.

[0030] The limiting and fixing assembly includes an adjusting groove 8 opened at the top of the T-shaped guide bar 6, an adjusting limiting rod 9 is provided inside the adjusting groove 8, a first limiting groove 10 corresponding to the size of the adjusting limiting rod 9 is opened on the inner wall of the top of the T-shaped movable groove 5, and the outer end of the adjusting limiting rod 9 is fixedly connected to the limiting plate 11, and a second limiting groove 12 is opened at the outer end of the adjusting groove 8, and the limiting plate 11 has the same size as the second limiting groove 12.

[0031] A cavity 13 is provided inside the adjustment limit rod 9, and two movable plates 14 are provided at both ends of the cavity 13. A limit block 15 is fixed to the outside of the movable plate 14, and one end of the limit block 15 extends to the front and rear sides of the adjustment limit rod 9. The inner side surface of one end of the limit block 15 is an arc surface. A third limit groove 16 is provided on the front and rear walls inside the adjustment groove 8, and one end of the limit block 15 is provided inside the third limit groove 16. A fourth limit groove 17 is provided on the front and rear walls inside the first limit groove 10, and the size of the fourth limit groove 17 is the same as the size of one end of the limit block 15.
