[0033] It further includes:

[0034] A height adjustment mechanism 1, and the height adjustment mechanism 1 is movably arranged in the top wall of the lower manhole cover 3;

[0035] The height adjustment mechanism 1 includes:

[0036] Two screws 1-1, and the two screws 1-1 are symmetrically rotated and passed through the top wall of the lower manhole cover 3 by threads; second hand-tightening members 14 are sleeved and fixed on the tops of the screws 1-1 to facilitate rotation adjustment and save manpower;

[0037] Two lifting plates 1-2, and the two lifting plates 1-2 are respectively movably arranged at the bottom ends of the screws 1-1 through bearings;

[0038] The telescopic rods 1-3, there are two of the telescopic rods 1-3, and they are respectively fixed to the top wall of the front and rear placement grooves of the lower manhole cover 3 by bolts, and the bottom ends of the telescopic rods 1-3 are fixed to the top wall of the lifting plate 1-2 by bolts. The lifting plate 1-2 is intermittently movably arranged in the placement groove of the lower manhole cover 3, and the telescopic rods 1-3 are located outside the screw rod 1-1; it is convenient to increase the height of the lower manhole cover 3 and the upper manhole cover 4 and eliminate the height difference between the manhole cover and the ground;

[0039] On the top wall of the manhole cover 3, two handles 15 are symmetrically welded left and right, and the handles 15 are located on the left and right sides of the screw rod 1-1. The handles 15 are located in the upper manhole cover 4, which is convenient for the staff to carry the lower manhole cover 3;

[0040] The driving shaft 8, the driving shaft 8 is rotatably arranged on the top wall of the upper manhole cover 4 through a bearing; a first hand-twist 9 is sleeved and fixed on the top end of the driving shaft 8, which is convenient for rotational adjustment and saves manpower;

[0041] The first bevel gear 10, the first bevel gear 10 is sleeved and fixed on the driving shaft 8;

[0045] When using the present utility model, the staff first manually rotates the second hand-twist 14, the second hand-twist 14 drives the screw rod 1-1 to rotate, the screw rod 1-1 drives the lifting plate 1-2 to move downward, the lifting plate 1-2 drives the telescopic rods 1-3 to stretch downward. During installation, the lifting plate 1-2 contacts the installation surface. As the lifting plate 1-2 extends out of the lower manhole cover 3, the height of the lower manhole cover 3 and the upper manhole cover 4 rises, until the top wall of the upper manhole cover 4 is coplanar with the ground surface. At this time, the height difference between the upper manhole cover 4 and the ground is eliminated, and water accumulation is avoided;

[0046] Next, the staff manually rotates the first hand-twist 9. The first hand-twist 9 drives the rotation of the driving shaft 8. The driving shaft 8 drives the rotation of the first bevel gear 10.
