The supporting structure 4 can lift the manhole cover 2 from the two arc-shaped support plates 23 while the clamping structure 3 is released, so as to facilitate manual removal of the manhole cover 2.

[0034] The sleeve hole 22 is designed to be sleeved on the top of the pressing rod 33 and to facilitate an external rod to press the pressing rod 33 .

[0035] Further as Figure 1-4As shown, it is worth specifically explaining that in order to quickly realize the fixed installation of the manhole cover 2, a clamping structure 3 is provided, which includes a longitudinal plate 31 movably overlapped at the bottom of the manhole cover 2, a fixed cylinder 32 is fixedly connected to the middle of the longitudinal plate 31, a pressure rod 33 is movably inserted into the inner side of the fixed cylinder 32, the top end of the pressure rod 33 passes through the sleeve hole 22 and protrudes from the top of the manhole cover 2, a movable block 34 is fixedly connected to the outer side of the pressure rod 33, the movable block 34 slides in the movable channel provided on the inner side of the fixed cylinder 32, and a sleeve arranged on the outer side of the pressure rod 33 is provided between the bottom end of the movable block 34 and the inner bottom wall of the movable channel The spring 35 and the bottom end of the pressure rod 33 movably penetrate the fixed tube 32, and two symmetrically arranged push-pull rods 36 are hinged on the outer wall thereof, and the two push-pull rods 36 are hinged at the opposite ends thereof with a clamping block 37, and the clamping blocks 37 are slidably sleeved on the outside of a guide rod 38 with a square structure in vertical cross section through a guide channel provided inside, and one end of the guide rod 38 is fixedly connected to the outside of the fixed tube 32, and an inclined surface a371 is provided on the opposite side wall of the two clamping blocks 37, and one end of the inclined surface a371 movably penetrates to the inner side of the slot and is clamped in the clamping groove 372 provided on the outer wall of the arc-shaped plug plate 21.

[0036] Among them, the setting of the inclined surface a371 can realize the clamping of the slot 372 set on the outer wall of the arc-shaped plug plate 21, and the top end of the pressing rod 33 is protruding to facilitate the external rod to press, so as to facilitate the two blocks 37 to be able to disengage from the slot 372, so that the two arc-shaped plug plates 21 can be pulled out of the movable channel respectively.

[0037] Further Figure 1-4 As shown, it is worth explaining in detail that in order to be able to synchronously lift the manhole cover 2 when the above-mentioned pressure rod 33 is pressed downward by the external rod, a top supporting structure 4 is provided, including a stopper 41 fixed to the top of the two blocks 37, and the two blocks 37 are provided with an inclined surface b42 at the opposite ends.
