[0038] The first connecting frame 31 and the second connecting frame 32 are both provided with a padding plate at the bottom;

[0039] Specifically, a certain space is reserved at the bottom of the first connecting frame 31 and the second connecting frame 32 for the limiting pin 34 to slide inside, so as to prevent the limiting pin 34 and the plug-in block 37 from contacting the surface of the column.

[0040] The device presses the two abutment blocks 74 on the plug block 4 on one side of the second column 2 into the groove 71, the support spring 73 is compressed, and the plug block 4 is inserted into the slot 5 at this time until the support spring 73 pushes the abutment block 74 into the slot 6 in the first column 1, thereby completing the connection between the second column 2 and the first column 1, and using the reinforcement member 3 to reinforce the connection between the first column 1 and the second column 2. When it needs to be removed, the reinforcement member 3 is removed and the two pressing blocks 84 are pressed, so that the pressing block 84 drives the limit pin to slide in the slot 6 and pushes the abutment block 74 back into the groove 71, separating the plug block 4 from the slot 5, wherein the limit ring 83 provided on the surface of the limit pin can prevent the movable pin 82 from detaching from the slot 6.
