The positioning component includes a fixing cavity 18, a positioning pin 19 and a telescopic spring 20. The fixing cavity 18 is installed on the outside of the mounting plate 1. The fixing cavity 18 is provided with a positioning pin 19 running through the inside of the fixing cavity 18. One end of the positioning pin 19 extends to the inside of the positioning hole 17. The outer wall of the positioning pin 19 is provided with a telescopic spring 20. The telescopic spring 20 is provided in the fixing cavity 18. The outer diameter of the positioning pin 19 is smaller than the inner diameter of the positioning hole 17. The positioning hole 17 and the positioning pin 19 form a snap-fit ​​structure. When in use, the device is moved to an appropriate position, and then the positioning pin 19 is pulled outward to place the mounting block 16 into the mounting hole 15. When the mounting hole 15 and the mounting block 16 are snap-fitted with each other, the positioning pin 19 is released. At this time, the telescopic spring 20 drives the positioning pin 19 to extend under the action of the elastic force, so that the positioning pin 19 and the positioning hole 17 are snap-fitted with each other, completing the convenient assembly of the support column 2, and the support column 2 can be conveniently disassembled and installed.
