Referring to fig. 2 and 5, a first adjusting mechanism 18 capable of controlling the well lid 2 to rotate towards the unscrewing direction of the first external thread 15 is arranged in the well lid 2, so that the first external thread 15 can be quickly separated from the internal thread 17.

Referring to fig. 2 and 6, a second adjusting mechanism 23 capable of controlling the rotation of the manhole cover 2 towards the unscrewing direction of the second external thread 16 is arranged in the manhole cover 2, so that the second external thread 16 can be quickly separated from the internal thread 17.

Referring to fig. 7 and 8, the first adjusting mechanism 18 includes a first adjusting block 181 hinged to a side wall of the control rod 71, and a first receiving block 182 is fixedly connected to an inner wall of the mounting hole 8. The side wall of the control rod 71 is provided with a first positioning block 19 for the first adjusting block 181 to abut against, so as to block the first adjusting block 181. A first torsion spring 20 for driving the first adjusting block 181 to rotate toward the first positioning block 19 is disposed between the control rod 71 and the first adjusting block 181, so as to achieve automatic resetting of the first adjusting block 181.

Referring to fig. 7 and 8, after the control rod 71 drives the first adjusting block 181 to move upward, the first adjusting block 181 can be located at a side of the first receiving block 182, and the first adjusting block 181 is located between the first receiving block 182 and the first positioning block 19.

When the control rod 71 is rotated to drive the first adjusting block 181 to rotate toward the first receiving block 182, the first positioning block 19 blocks the first adjusting block 181. Subsequently, the first adjusting block 181 can push the first receiving block 182 to drive the well lid 2 to rotate, and the first external thread 15 is separated from the internal thread 17.

Referring to fig. 3 and 8, the first spacing post 21 of one side fixedly connected with that first locating block 19 was kept away from to first regulating block 181, the first spacing groove 22 that supplies first spacing post 21 male is seted up to the lateral wall of first holding block 182 to realize that the position of the vertical direction of first regulating block 181 is injectd, avoid first regulating block 181 and first holding block 182 to take place the dislocation, thereby make the first holding block 182 of drive that first regulating block 181 can be stable drive well lid 2 and rotate.

Referring to fig. 7 and 9, the second regulation mechanism 23 includes a second regulation block 231 hinged to a side wall of the lever 71, and the first regulation block 181 is located above the second regulation block 231. Meanwhile, the inner wall of the mounting hole 8 is fixedly connected with a second receiving block 232 located below the first receiving block 182.

Referring to fig. 7 and 9, a second positioning block 24 for abutting against the second adjusting block 231 is disposed on a side wall of the control rod 71, so as to block the second adjusting block 231. A second torsion spring 25 for driving the second adjusting block 231 to rotate towards the second positioning block 24 is arranged between the control rod 71 and the second adjusting block 231, so as to realize automatic resetting of the second adjusting block 231.

Referring to fig. 8 and 9, when the control rod 71 drives the first adjusting block 181 and the second adjusting block 231 to move upward and the second adjusting block 231 is moved to the side of the second receiving block 232, the first adjusting block 181 is separated from the first receiving block 182, so as to prevent the first adjusting block 181 and the first receiving block 182 from interfering with the rotation of the manhole cover 2.

When the second adjusting block 231 moves to the side of the second receiving block 232, the rotating control rod 71 drives the second adjusting block 231 to rotate towards the second receiving block 232, and then the second positioning block 24 blocks the second adjusting block 231. Next, the second adjusting block 231 can push the second receiving block 232 to drive the well lid 2 to rotate, and the second external thread 16 is separated from the internal thread 17.

At this time, the support ring 12 forms an electromagnet with the wire 132, and a repulsive force is formed between the support ring 12 and the permanent magnet 131. Subsequently, the support ring 12 drives the control rod 71, the control block 72, the first adjusting block 181, and the second adjusting block 231 to move upward. Then, the locking ring 9 drives the locking rod 5 to move reversely under the pushing of the spring 10, and the locking rod 5 is disengaged from the locking groove 6.

Subsequently, the supporting ring 12 is pulled to drive the control rod 71, the control block 72, the first adjusting block 181, the second adjusting block 231 and the like to move upward, when the pointer 28 is aligned with the first indicating ring 29, the first position-limiting column 21 is aligned with the first position-limiting groove 22, and the second adjusting block 231 and the second receiving block 232 are in a separated state. Then, the support ring 12 is rotated to drive the control rod 71, the control block 72, the first adjusting block 181, the second adjusting block 231, and other components to rotate toward the first receiving block 182, and at this time, the first positioning block 19 blocks the first adjusting block 181. Subsequently, the first position-limiting column 21 is inserted into the first position-limiting groove 22, and then the first adjusting block 181 pushes the first receiving block 182 to move, and the first external thread 15 is disengaged from the internal thread 17.

Subsequently, pulling the supporting ring 12 drives the control rod 71, the control block 72, the first adjusting block 181, the second adjusting block 231 and so on to move upward, when the pointer 28 is aligned with the second indicating ring 30, the second position-limiting post 26 is aligned with the second position-limiting groove 27, and the first adjusting block 181 is separated from the first receiving block 182. Then, the supporting ring 12 is rotated to drive the control rod 71, the control block 72, the first adjusting block 181, the second adjusting block 231 and other components to rotate toward the direction of the second receiving block 232, and at this time, the second positioning block 24 blocks the second adjusting block 231. Subsequently, the second limit column 26 is inserted into the second limit groove 27, and then the second adjusting block 231 pushes the second receiving block 232 to move, so that the second external thread 16 is separated from the internal thread 17, thereby unlocking the well lid 2. Subsequently, the user can take out well lid 2 from the well body 1 to try the dismantlement of well lid 2.
