[0018] In order to more clearly understand the above objects, features, and advantages of the present utility model, the following will further illustrate the present utility model in conjunction with 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.
[0019] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0020] Embodiment 1, as Figure 1 shown, a special tool for opening the coal charging hole cover includes a long rod 1. The long rod 1 serves as the main part, providing sufficient length for convenient lever action, facilitating the operation of workers in a high-temperature environment, avoiding direct contact with the coal charging hole cover, and ensuring safety. The top of the long rod 1 is connected with a pointed head 2, and the pointed head 2 is used to insert into or pry the gap of the coal charging hole cover to help open the coal charging hole cover, facilitating accurate positioning and force application, and improving the operation efficiency.
[0021] A bent handle 3 is connected to the bottom of the long rod 1. The bent handle 3 makes the operation more labor-saving and convenient to grip. A connecting seat 7 is horizontally arranged on the long rod 1. Both ends of the connecting seat 7 are connected with grips 8. The grips 8 provide additional support, enabling workers to hold and apply force easily. The design conforms to ergonomics, providing a comfortable gripping experience and reducing the fatigue caused by long-term operation. The grips 8 can be conveniently connected and disassembled through the connecting seat 7.
[0022] The following specifically describes the specific designs of the above key components:
[0023] The end of the bent handle 3 is set as a hook head 4. The hook head 4 is used to grab or hook the coal charging hole cover, making the opening and closing operations more convenient, especially playing a great role when rotation or pulling is required.
