Specific implementation

[0037] In order to make the purpose, characteristics and advantages of the utility model more obvious and easy to understand, the technical solutions in the utility model will be described clearly and completely in combination with the drawings in the specific embodiments. Obviously, the embodiments described below are only some of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the patent, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the patent protection.

[0038] As shown in Figures 1-11 , it relates to a high-altitude operation device with climbing function, comprising a main platform 100 and an extension platform 200, further comprising a pedal piece 300, the extension platform 200 is provided with a mounting bracket 210, one end of the pedal piece 300 is hinged with the mounting bracket 210, so that the pedal piece 300 can rotate along the set axis and exist in a first state and a second state; in the first state, the extension direction of the pedal piece 300 is horizontal with the extension direction of the extension platform 200; in the second state, the extension direction of the pedal piece 300 is crossed with the extension direction of the extension platform 200.

[0039] In the embodiment, as shown in Figure 1 , 2 , the main platform 100 is a cuboid plate structure horizontally placed, the extension platform 200 is also a cuboid plate structure horizontally placed, and the size of the main platform 100 is larger than that of the extension platform 200, so that the extension platform 200 can be accommodated in the main platform 100, wherein one end of the main platform 100 along its length is provided as an opening to allow the extension platform 200 to move through the opening, the bottom or both sides of the extension platform 200 are movably connected with the main platform 100, and the extension platform 200 can move in the main platform 100 along the length direction of the main platform 100, thereby forming an extension state and a storage state. When a larger horizontal operation space is needed, the extension platform 200 is moved outward relative to the main platform 100, so that the extension platform 200 moves out of the main platform 100 by a part through the opening, thereby expanding the horizontal operation space of the main platform 100 to reach the extension state; when a larger horizontal operation space is not needed, the extension platform 200 can be moved in the opposite direction, so that the extension platform 200 can be accommodated in the main platform 100 as a whole, further reducing the overall volume of the device, thereby facilitating operation in a small space.

[0040] The mounting bracket 210 can be a vertical pipe structure arranged on the extension platform 200. For example, in the present example, the mounting bracket 210 is four vertical pipes uniformly distributed on the extension platform 200. The pedal member 300 is a cuboid plate structure.

The pedal member 300 is close to the mounting bracket 210, thereby not occupying the horizontal operation space of the extension platform 200. When the climbing operation is needed, the pedal member 300 is rotated downward to a horizontal state of the whole pedal member 300 and the extension platform 200, thereby achieving the first state. The user climbs on the pedal to achieve the additional climbing operation. The pedal member 300 can rotate 0-90° during the conversion between the first state and the second state.
