After the connection is completed, the protective device 3 is used to reinforce them, and the first mounting sleeve 31 and the second mounting sleeve 32 of the protective device 3 are sleeved on the surfaces of the two flanges 6, so that the two positioning members 311 installed on one side of the first mounting sleeve 31 are completely inserted into the second mounting sleeve 32. When the two positioning members 311 are inserted, with the cooperation of the return springs 51 and the two sliding members 52 in the two positioning components 5, the two positioning pins 53 in the two positioning components 5 are controlled to complete the limited fixation of the two positioning members 311 in the second mounting sleeve 32.
