[0029] like Figure 1 As shown, the four vertical rods 2 are provided with straight grooves 7 inside, and a portion of the slider 3 is slidably connected inside the straight groove 7 , and the slider 3 is fixedly connected to the cross rod 10 .

[0030] like Figure 1 As shown, T-shaped slots 6 are formed inside the four bottom bars 8 , and a portion of the fixing block 5 is slidably connected inside the T-shaped slots 6 .
