[0033] The height of the first support frame 2 is equal to the height of the second support frame 6. The inner wall at the top of the placement plate 1 corresponds to the right side of the top of the slide groove 5 and is slidably connected to the limiting column 14. The middle part of the rod body of the limiting column 14 is fixedly connected with a pressure plate 13. The outer wall of the pressure plate 13 is slidably connected to the right side of the top of the slide groove 5 corresponding to the inner wall of the placement plate 1. The top of the pressure plate 13 is fixedly connected to the outer wall of the limiting column 14 near the top of the limiting column 14. The top of the spring 12 is fixedly connected to the inner wall of the placement plate 1. The top of the limiting column 14 penetrates the outer wall of the placement plate 1 and is fixedly connected to the limiting disk 7. The diameter of the limiting disk 7 is larger than the diameter of the limiting column 14. A jack is set on the left side of the top of the slider 8. The limiting column 1 The shape of the outer wall at the bottom end of 4 matches the shape of the insertion hole. After the support frame is opened, the limit plate 7 can be pulled so that the pressure plate 13 of the limit column 14 can slide on the inner wall of the placement plate 1 and be inserted into the insertion hole in the slider 8 under the action of the restoring force of the spring 12, so that the placement plate 1 can be stably placed between the two groups of first support frames 2 and second support frames 6.
