[0056] Specifically, when the grille 4.1 is located in the fixed frame 4.2, the distance between the grille 4.1 and the inner sides of the fixed frame 4.2 is 1 mm, and wood screws are inserted into the fixed frame 4.2 from the sides of the fixed frame 4.2 to fix the fixed frame 4.2 and the grille 4.1 together.

[0057] When the upper end of the suspension rod 2 and the gap groove 3 in the support member 1 are fixed together, a gasket 7 is also required. Specifically, the upper end of the suspension rod 2 will pass through the gap groove 3 from bottom to top, and a gasket 7 is provided on the upper and lower surfaces of the support member 1; a first nut is provided on the suspension rod 2 at the bottom of the gasket 7 on the lower side to fix the suspension rod 2 and the lower side of the support member 1, and at the same time, the thread of the upper end of the suspension rod 2 passes through the gasket 7 on the upper side, and then a second nut is provided to fix the suspension rod 2 and the upper side of the support member 1. The use of the gasket 7 can increase the force area of ​​the nut and prevent the nut from being damaged and loosened. At the same time, there will be a large static friction between the gasket 7 and the support member 1 in the horizontal direction, thereby preventing the suspension rod 2 from being displaced in the horizontal direction.

[0058] In addition, a fixing plate 8 is welded at both ends of the support member 1, and six positioning holes 9 are set on the fixing plate 8. Similarly, six wood screws are used to fix the support member 1 to the wooden beam 5 through the positioning holes 9, thereby completing the fixation of the support member 1 on the wooden beam 5.
