The top ends of the two second support rods 25 are provided with mutually meshing teeth.

The bottom ends of the two second support rods 25 are rotatably connected to the first support rod 24. The middle sections of the two first support rods 24 are slidably connected to each other. The end of the connecting shaft 29 away from the second transmission rod 23 passes through the two first support rods 24 in sequence. The two first support rods 24 are driven to move at the same time through the connecting shaft 29, thereby improving the height adjustment stability of the support plate 3.

[0033] A support block 28 is fixedly connected to the upper surface of the fixed plate 1 , and two limit rods 27 are rotatably connected to the inner side wall of the support block 28 .
