When one end of each limit plate 15 passes through the preset mounting hole on the outer surface of the tower crane, the device can be quickly assembled with the tower crane.

[0025] The working principle of this utility model is as follows: When it is necessary to assemble the guardrail 8 and the walkway body 4 together, the first group of workers first moves the circular plate 6. Each movement of the circular plate 6 stretches the first spring 2 and drives the limit pin 17 to move. Then, the second group of workers inserts the two insert plates 13 installed on the bottom surface of the guardrail 8 into the two limit slots 18 respectively. Then, the first group of workers releases the circular plate 6. Each contraction of the first spring 2 drives the circular plate 6 and the insert plate 13 to move. When one end of each insert plate 13 passes through the limit hole 20, the guardrail 8 and the walkway body 4 can be quickly assembled together.
