When the overall transportation is inconvenient, we can disassemble the table legs. First, press the round head pin 2-5-16 to retract it into the reducing tube 2-5-1. The pressing force pushes the sliding member 2-5-15 to slide on the slide groove 2-5-14. After the sliding member 2-5-15 hits the elastic member, the force is transmitted to the elastic member to make it shrink. The round head pin 2-5-1 is pressed all the time, and then the support rod 2-5 is disassembled from the extension rod 3-3 and the vertical rod 2-1. Then the pin 3-2-1 fixed with bolts is removed to realize the disassembly of the U-shaped frame 3-1 and the extension rod 3-3. Since the vertical rod 2-1 and the U-shaped frame are 3-1 are hinged to the table top 1, and the vertical rod 2-1 and the U-shaped frame 3-1 can also be rotated to fit the bottom surface of the table top 1. In addition, the elastic member placement block 2-5-9 of the elastic member fixing assembly 2-5-2 is a movable connection. When the elastic member is damaged after being used for a certain number of times, we can take out the elastic member placement block 2-5-9 and replace the elastic member; when the round table needs to be reassembled, just use bolts to re-fix the pin 3-2-1, and then extend the reducer 2-5-1 end of the support rod 2-5 into the matching hollow part of the vertical rod 2-1 and the extension tube 3-3. When the fixing hole of the reducer 2-5-1 coincides with the fixing hole on the vertical rod 2-1 and the extension tube 3-3, the round head pin 2-5-16 extends out to fix them.
