[0024] Please refer to Figures 1-3, in the embodiment of the present utility model: The positioning assembly 6 includes: a movable sleeve 602, a connecting rod 601, and a movable rod 606. The movable sleeve 602 is movably sleeved on the surface of the lower end of the fixed cylinder 3. There are two connecting rods 601, and the two connecting rods 601 are symmetrically and fixedly installed at the bottom of the fixed cylinder 3. The lower end of the connecting rod 601 movably penetrates to the bottom of the movable sleeve 602. A connecting plate 604 is fixedly connected between the bottoms of the two connecting rods 601. A return spring 605 is sleeved on the surface of the lower end of the connecting rod 601, and one end of the return spring 605 is fixedly connected to the bottom of the movable sleeve 602, and the other end of the return spring 605 is fixedly connected to the surface of the top of the connecting plate 604. A pressing column 603 is fixedly installed on the inner bottom of the movable sleeve 602, and the upper end of the pressing column 603 movably penetrates into the interior of the fixed cylinder 3. There are four movable rods 606, and the four movable rods 606 are hinged and installed on the surface of the upper end of the movable sleeve 602 at equal intervals along the circumference. One end of the movable rod 606 is hinged and installed with the other end of the bottom of the adjacent limiting rod 4. When it is necessary to remove the manhole cover 2 from the top of the power well body 1, after opening the shielding cover 5, the pressing column 603 inside the fixed cylinder 3 is pressed by a tool. At this time, the pressing column 603 drives the movable sleeve 602 to move downward, so that the return spring 605 at the bottom of the movable sleeve 602 is compressed and contracted. During the downward movement of the movable sleeve 602, the four movable rods 606 hinged along the circumference on the upper surface of the movable sleeve 602 pull the corresponding limiting rods 4 to move synchronously in the direction of the fixed cylinder 3, so that one end of the limiting rod 4 is disengaged from the insertion of the corresponding limiting groove 101.

[0026] Working principle: When performing underground maintenance on a municipal power well and it is necessary to remove the manhole cover 2 from the top of the power well body 1, after opening the shielding cover 5, press the pressing column 603 inside the fixed cylinder 3 with a tool. At this time, the pressing column 603 drives the movable sleeve 602 to move downward, causing the return spring 605 at the bottom of the movable sleeve 602 to be compressed and contracted. During the downward movement of the movable sleeve 602, the four movable rods 606 hinged along the circumference of the upper surface of the movable sleeve 602 pull the corresponding limiting rods 4 to move synchronously towards the fixed cylinder 3, so that one end of the limiting rod 4 releases the insertion into the corresponding limiting groove 101. By pulling the pull ring on the top of the manhole cover 2, the manhole cover 2 can be removed. When the pressing on the pressing column 603 is released, the return spring 605 is elastically reset under force, causing the return spring 605 to push the movable sleeve 602 upward, enabling the movable rod 606 to quickly push the corresponding limiting rod 4 into the corresponding limiting groove 101 to complete the quick installation of the manhole cover 2. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
