The face 56 has a first window 60 and a second window 62, wherein a contact member 58 protrudes from the face 56 and toward a direction opposite to the top and bottom walls 52, 54. A difference of height is formed between the contact member 58 and the face 56, so that a room 66 is defined between the contact member 58 and the face 56. The contact member 58 has a contact portion 64 which is located adjacent to the second window 62. The first window 60 is located close to the end of the side wall 42 from which the end wall 44 extends. The end wall 44 is located close to the first window 60 and substantially perpendicularly to the face 56 of the side wall 42. The end wall 44 has at least one positioning hole 68. In one embodiment of the present invention, the side wall 42 has two lugs 61 and two supports 63, wherein the lugs 61 protrude from the top wall 52 and the bottom wall 54 respectively and extend toward the protruding direction of the contact member 58. The two lugs 61 are located close to two sides of the second window 62. Each of the two lugs 61 has a hole 65, and the holes 65 of the two lugs 61 are located corresponding to each other. The two supports 63 are located between the two lugs 61. Each of the two supports 63 has an arc concave 67 located corresponding to the holes 65 of the two lugs 61. The two supports 63 extend and protrude from the edge of the second window 62. The stop 46 has a first portion 70, a second portion 72 and a middle portion 74 which is connected to the first and second portions 70, 72. The first and second portions 70, 72 are located symmetrically with each other. Each of the first and second portions 70, 72 has a first side 76, a second side 78 and a connection wall 80 which is connected between the first and second sides 76, 78. Each of the first and second sides 76, 78 has a hole 77. The two respective holes 77 of the first and second sides 76, 78 are located symmetrically with each other. The first side 76 has an extension section 82. The middle portion 74 has a first end portion 84 and a second end portion 86 which is located corresponding to the first end portion 84. The resilient member 48 has a bent portion 88 and a fork portion 90. The bent portion 88 is located corresponding to the contact portion 64 of the contact member 58. The fork portion 90 has a recessed area 92 located corresponding to the second end portion 86 of the middle portion 74 of the stop 46. The at least one installation member 50 is located corresponding to the positioning hole 68 of the end wall 44. A pivotal member 47 is configured to the holes 77 on the first and second sides 76, 78 of the first and second portions 70, 72 of the stop 46, the holes 65 of the lugs 61 of the side wall 42, the arc concaves 67 of the supports 63 of the side wall 42. It is noted that the first and second mounting brackets 34, 36 have the same structure, the second mounting bracket 36 needs not to be described in detail.

[0017] FIGS. 3A and 3B show that the stop 46 is pivotably connected to the side wall 42 by extending the pivotal member 47 through the holes 77 on the first and second sides 76, 78 of the first and second portions 70, 72 of the stop 46, the holes 65 of the lugs 61 of the side wall 42, the arc concaves 67 of the supports 63 of the side wall 42. The resilient member 48 is partially inserted into the room 66 between the face 56 of the side wall 42 and the contact member 58. The bent portion 88 of the resilient member 48 contacts the contact portion 64 of the contact member 58, and the fork portion 90 of the resilient member 48 contacts the second end portion 86 of the middle portion 74 of the stop 46. The stop 46 is applied by the force from the resilient member 48, and the extension section 82 of the stop 46 abuts against the face 56 of the side wall 42 to maintain the stop 46 at a pre-set position. The at least one installation member 50 is fixed to the end wall 44. When in assembling, the first mounting bracket 34 partially extends through the hole 26 of the third post 22, from outside toward inside, and is positioned by the at least one installation member 50, so that the first mounting bracket 34 is installed to the third post 22, and the first end portion 84 of the middle portion 74 of the stop 46 is located corresponding to the third post 22. In detail, a surface 83 of the middle portion 74 of the stop 46 of the first mounting bracket 34 first contacts the third post 22, and a force F1 is applied to let the stop 46 overcome the force of the resilient member 48 and swing an angle. The at least one installation member 50 is aimed to the hole 26 of the third post 22, and a force F2 is applied to the installation member 50 which then partially extends through the hole 26. In the meanwhile, the stop 46 is moved away from the third post 22, and returns to its pre-set position by the force released from the resilient member 48. Therefore, the first mounting bracket 34 is installed to the third post 22.

[0018] FIG. 4 shows that the first mounting bracket 34 is installed to the third post 22, the installation member 50 of the first mounting bracket 34 extends through the hole 26 of the third post 22, and by being located adjacent to the third post 22, the first end portion 84 of the middle portion 74 of the stop 46 of the first mounting bracket 34 blocks the way that the installation member 50 is removed from the third post 22. Therefore, the installation member 50 is installed to the third post 22 by the stop 46 of the first mounting bracket 34. By the blocking of the stop 46, the installation member 50 does not remove from the third post 22.

[0019] FIGS. 5 and 6 show the operation of removing the first mounting bracket 34 from the third post 22. First, a force F3 is applied to the middle portion 74 of the stop 46 of the first mounting bracket 34, and overcomes the force from the resilient member 48, so that the stop 46 pivots an angle relative to the pivotal member 47. Preferably, the first end portion 84 of the middle portion 74 of the stop 46 is partially inserted into the first window 60 to remove the blocking of the stop 46 from the third post 22, so that the installation member 50 of the first mounting bracket 34 can be removed from the hole 26 of the third post 22, and the first mounting bracket 34 is removed from the third post 22.

[0020] FIG. 7 shows the second embodiment of the present invention, wherein the stop 200 of the first mounting bracket 34 can only comprise the first portion 202 and the middle portion 204. The middle portion 204 has a side plate 206 to fix the resilient member 48.

[0021] FIG. 8 shows the third embodiment of the present invention, wherein the resilient member 300 has two bent portions 302 at two ends thereof respectively. The two bent portions 302 respectively contact the contact member 58 of the first mounting bracket 34 and the second end portion 86 of the stop 46.
