[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1-4 shown, the present utility model provides a port manhole cover opening device, including: a connecting rod 2, both outer surfaces of the connecting rod 2 near the top are fixedly connected with rotating rods 14, both end faces of the two rotating rods 14 are rotatably connected with support rods 1, the bottom of the connecting rod 2 near the left side is fixedly connected with a rotating seat 5, the inner surface of the rotating seat 5 is rotatably connected with a hook 6, a movable rod 7 is inserted into the inner surface of the connecting rod 2, two card slots 4 are opened at the top of the connecting rod 2, an installation groove 12 is opened at the top of the movable rod 7 near the left side, a telescopic rod 15 is fixedly connected to the inner bottom of the installation groove 12, a spring 13 is sleeved on the outer surface of the telescopic rod 15, the top of the telescopic rod 15 is fixedly connected with a clamping block 3, the outer surface of the clamping block 3 is matched with the inner surface of the installation groove 12, the outer surface of the clamping block 3 is clamped with the inner surfaces of the two card slots 4, a handle 9 is fixedly connected to the left surface of the movable rod 7, a buckle 11 is fixedly connected to the bottom of the connecting rod 2, and the buckle 11 is matched with the hook 6.

[0023] The effect achieved by the entire Embodiment 1 is that when opening the manhole cover of the sewer well, by pressing the clamping block 3, the clamping block 3 moves into the installation groove 12, driving the compression of the spring 13 and the telescopic rod 15. Then, by pulling the handle 9 outward, the movable rod 7 is driven to move inside the connecting rod 2. When the movable rod 7 moves to a suitable position, the installation groove 12 aligns with another clamping groove 4, so that the clamping block 3 is no longer under pressure. Then, under the action of the spring 13 rebounding, the clamping block 3 is driven to push outward. The telescopic rod 15 ensures the movement track of the clamping block 3, making the clamping block 3 move into the clamping groove 4 and engage with it to limit the position of the movable rod 7. Then, the hook 6 is removed from the buckle 11, and with the assistance of the rotating seat 5, the hook 6 can rotate on the connecting rod 2. Then, the bottoms of the two support rods 1 are in contact with the ground. At the same time, under the action of the two rotating rods 14, the connecting rod 2 can rotate with the support rod 1. Then, the hook 6 is inserted into the hole at the bottom of the manhole cover, and then the handle 9 is pressed downward. Using the lever principle, the manhole cover can be easily opened, saving manpower and avoiding the need for mechanical assistance, with high practicability. When not in use, the connecting rod 2 is placed vertically, making the two support rods 1 and the connecting rod 2 form a horizontal state. Then, the clamping block 3 is pressed to disengage it from the corresponding clamping groove 4, and then the handle 9 is pressed downward, making the movable rod 7 move into the connecting rod 2, and the clamping block 3 is used to snap into the bottom clamping groove 4 to complete the fixation of the movable rod 7. Then, the hook 6 is snapped into the buckle 11 for fixation, thus facilitating the deployment and retraction of the device and making it convenient to carry and use.

[0024] Embodiment 2 is as Figures 1-4 shown, a sleeve 8 is fixedly connected to the outer surface of the handle 9, and the inner surface of the sleeve 8 is provided in a matching manner with the outer surfaces of the two support rods 1.

[0025] The effect achieved by the entire Embodiment 2 is that when the movable rod 7 is fully retracted, through the setting of the sleeve 8, the sleeve 8 limits the two support rods 1 to prevent them from rotating, further improving the convenience of carrying.

[0026] Working principle: When opening the manhole cover of the sewer well, by pressing the clamping block 3, the clamping block 3 moves into the installation groove 12, driving the spring 13 and the telescopic rod 15 to be compressed. Then, by pulling the handle 9 outward, the movable rod 7 is driven to move inside the connecting rod 2. When the movable rod 7 moves to a suitable position, the installation groove 12 aligns with another clamping groove 4, so that the clamping block 3 is no longer under pressure. Then, under the action of the spring 13 rebounding, the clamping block 3 is driven to push outward. The telescopic rod 15 ensures the movement track of the clamping block 3, making the clamping block 3 move into the clamping groove 4 and engage with it to limit the position of the movable rod 7. Then, the hook 6 is removed from the buckle 11, and with the assistance of the rotating seat 5, the hook 6 can rotate on the connecting rod 2. Then, the bottoms of the two support rods 1 are in contact with the ground. At the same time, under the action of the two rotating rods 14, the connecting rod 2 can rotate with the support rod 1. Then, the hook 6 is inserted into the hole at the bottom of the manhole cover, and then the handle 9 is pressed downward. Using the lever principle, the manhole cover can be easily opened. When not in use, the connecting rod 2 is placed vertically, making the two support rods 1 and the connecting rod 2 form a horizontal line. Then, the clamping block 3 is pressed to disengage it from the corresponding clamping groove 4. Then, the handle 9 is pressed downward, making the movable rod 7 move into the connecting rod 2, and the clamping block 3 is used to snap into the bottom clamping groove 4 to complete the fixation of the movable rod 7. After retraction, through the setting of the sleeve 8, the sleeve 8 limits the two support rods 1 to prevent them from rotating. Then, the hook 6 is snapped into the buckle 11 for fixation, thus facilitating the deployment and retraction of the device and making it convenient to carry and use.

[0027] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
