Therefore, the present invention is not limited by the specific embodiments disclosed below.

Second, reference herein to "one embodiment" or "an embodiment" refers to a particular feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in various places in this specification are not all referring to the same embodiment, nor are they separate or selectively mutually exclusive from other embodiments.

Example 1:

Referring to Figures 1-9 of the description, when the hole of the manhole cover is in the shape of a strip, the moving device is integrated to the top of the manhole cover, the angle adjustment motor 207 is activated, and the second shaft 208 rotates. The turntable 301 is driven by the upper hurdle 206 to rotate, thereby adjusting the angle of the opening clip assembly 300 so that the opening clip assembly 300 is on the connection line of the manhole cover hole, and then two sets of distance adjustment motors 202 are activated, and the first rotating shaft 203 drives the main gear 204 Rotating, the main gear 204 meshes with the rack portion 205a of the translation base 205, thereby driving the translation base 205 to move in the translation slot 201a as a whole. Length (as shown in Figures 5 and 6 of the accompanying drawings in the description), the longer rack portion 205a can ensure the movable distance of the translation base 205, thereby increasing the adjustable range of the distance between the two sets of opening and clamping assemblies 300, and the shorter When the two groups of translation bases 205 share the translation slot 201a, the connection part 205b can prevent premature contact and collision when they are close to each other, and can also ensure the movable distance of the translation bases 205, thereby improving the opening and clamping of the two groups. Adjustable range of spacing between components 300 . When moving the fixing clip 303 for opening the clip assembly 300 to just above the hole in the manhole cover, shorten the hydraulic lifting column 209 downward, move the fixing clip 303 down until it is close to the top of the manhole cover, and then rotate the rotating rod 302 to make the fixing The length direction of the clamp 303 is aligned with the length direction of the manhole cover hole, continue to shorten the hydraulic lift column 209 so that the fixed clamp 303 enters the bottom of the manhole cover through the manhole cover hole, and then rotate the rotating rod 302 approximately 90° to extend the hydraulic lift column 209 upward. After that, the manhole cover can be lifted and opened by contacting the fixing clip 303 with the bottom of the manhole cover.
