[0022] In particular, a connecting frame 5 is fixedly connected to one side of the well seat 1, and the connecting frame 5 and the well seat 1 are made as one piece. A connecting block 6 is fixedly connected to one side of the well cover 2, and the well cover 2 and the connecting block 6 are made as one piece. A connecting assembly 7 is arranged between the connecting block 6 and the connecting frame 5, and the connecting assembly 7 includes two connecting shafts 71 and two limiting plates 72. Through holes are provided on the sides of the connecting frame 5 and the sides of the connecting block 6. The outer wall of the connecting shaft 71 is slidably sleeved with the inner cavity of the through hole. The connecting block 6 is located inside the connecting frame 5, so that the connecting block 6 can be rotated relative to the connecting frame 5 through the connecting shaft 71, so that the well cover 2 can be flipped open or closed relative to the well seat 1. A mounting groove 73 connected to the inner cavity of the through hole is provided at the bottom of the connecting block 6. The limiting plate 72 is located inside the mounting groove 73 and is locked to the connecting shaft 71. A slot is provided at the top of the limiting plate 72, and an annular groove 74 is provided on the outer wall of the connecting shaft 71.
