[0002] With the rapid development of urban rail transit, the subway, as an important part of urban public transportation, is of vital importance for its safe and stable operation. The daily maintenance and care of subway vehicles is one of the key links to ensure their normal operation. In the maintenance process of subway vehicles, the removal and replacement of bolts are common operations. Since subway vehicles have been running in a complex and changeable environment for a long time, bolts and nuts often rust and deform, which makes it difficult for conventional disassembly tools to work effectively, bringing great difficulties to maintenance work.

[0003] There are some bolt breaking devices on the market to solve the problem of difficult bolt removal. However, the bolts used in subway vehicles are of different sizes. When breaking smaller bolts, it is more flexible and easy to use to use a small-sized breaking device, but when breaking smaller-sized bolts, a small-sized breaking device is difficult to adapt. As a result, when repairing subway vehicles, a single breaking device is difficult to adapt to bolts and nuts of different sizes and shapes. Therefore, maintenance personnel need to carry multiple breaking devices of different sizes, which is troublesome to carry. For this reason, we propose a bolt breaking device for subway vehicle maintenance. Utility Model Content
