The placement table 400 includes a top plate 401, a fixed bottom plate 402, a cylinder 403 and a rolling assembly 404. The top plate 401 is set on the inner side of the bracket 100 for lifting, and the fixed bottom plate 402 is fixed on the inner side of the bracket 100 and is located below the top plate 401. The cylinder 403 is installed on the fixed bottom plate 402, and the top end of the cylinder 403 is fixedly connected to the bottom surface of the top plate 401. The cylinder 403 can be started to push the top plate 401 together with the outer frame 800 thereon, thereby realizing the height adjustment of the outer frame 800, which is convenient for the outer frame 800 to fit tightly with the taut wire mesh 500.

[0024] In this embodiment, preferably, the rolling component 404 is arranged between the edge of the top plate 401 and the inner wall of the bracket 100. The rolling component 404 is arranged at four places to improve the smoothness and stability of the top plate 401 during the lifting and lowering process. The rolling component 404 includes a fixed rod 4041, a rolling seat 4042 and a lifting groove 4043. The fixed rod 4041 is fixed to the bottom of the edge of the top plate 401, and the rolling seat 4042 is fixedly connected to the bottom end of the fixed rod 4041 and is rollingly connected to the lifting groove 4043 opened on the inner wall of the bracket 100. During the lifting and lowering of the top plate 401, the rolling seat 4042 will roll inside the lifting groove 4043.

[0025] In this embodiment, preferably, the placement table 400 also includes a fixing component 405, which is arranged between the fixed base plate 402 and the cylinder 403, and is used to fix and install the cylinder 403. The fixing component 405 includes a fixing plate 4051, a bolt 4052 and a nut 4053.
