[0007] As a preferred technical solution for operating the manhole cover opening device, it also includes a pulling part, which is connected to the base.

[0008] As a preferred technical solution for operating the manhole cover opening device, the base also includes a movable block, which is slidably disposed on the seat and provides a force support point for the opening part.

[0009] As a preferred technical solution for operating the manhole cover opening device, the pulling part is connected to the moving block.

[0010] As a preferred technical solution for operating a manhole cover opening device, the opening part and the moving block can be detachably coupled.

[0011] The beneficial effects of the manhole cover opening device provided by this utility model are: during use, this utility model can be placed directly on the ground, and the manhole cover can be lifted and dragged by foot by utilizing the assistance between the base and the opening part. Compared with the prior art, this utility model is easier to use, and therefore safer and more efficient. Attached Figure Description

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0023] One embodiment of this utility model provides a manhole cover opening device, including a base and an opening part. The base is movable on the ground, and the opening part and the base form a lever effect for opening the manhole cover. Then, by moving the base on the ground, the opening part is moved to drag the pried-open manhole cover.

[0024] The above describes the basic usage process of this utility model. For details regarding the structural configuration of this utility model, please refer to [link / reference needed]. Figure 1-4 In this utility model, the base consists of a seat 1, a movable wheel 3 mounted on the seat 1, and a movable block 2 slidably mounted on the seat 1. The opening part is a pry bar 5, one end of which is movably engaged with the movable block 2 to form a lever effect. When one end of the pry bar 5 is stepped on, the other end pries open the manhole cover. When the seat 1 is dragged, the manhole cover can be moved. Furthermore, as... Figure 5 As shown, the crowbar 5 and the movable block 2 can be connected by an overlapping joint, so that they can be separated afterwards for easy carrying.

[0025] Furthermore, refer to Figure 1-4 This utility model also includes a pulling part, which can be a pull rod 4, to facilitate the movement of the base 1. Specifically, the pull rod 4 is connected to the moving block 2, so that when the manhole cover is opened, after the manhole cover is pried up, the foot is first used to brace against the base 1, and then the pull rod 4 is pulled. After the moving block 2 slides a certain distance on the base 1, part of the force of the manhole cover is fully engaged with the base 1. Then the foot is removed, and the pull rod 4 is pulled again to move the base 1 to complete the overall dragging. This structural configuration allows the weight of the manhole cover to fall fully on the base 1 when it is lifted, thereby reducing the friction between the manhole cover and the ground, and further achieving the effect of saving effort.

[0026] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
