[0002] With the rapid development of China's economic construction, the energy demand is extremely large. As the main source of China's energy supply, coal resources are difficult to change in the next long period, resulting in the continuous development of the coal industry towards mechanization and automation. Due to reasons such as coal and rock properties, burial depth, and in-situ stress in most coal mines in China, the floor heave of roadways is serious, which affects the safety of roadway use and restricts the safe production of mines. Therefore, the task of floor reinforcement and treatment is arduous. At present, the most important means for coal mine floor reinforcement and treatment in China is bolt support.

[0003] In the prior art, when processing an anchor rod by welding, cutting, etc., it is usually necessary to clamp both ends of the anchor rod respectively. The operation steps are relatively cumbersome, the clamping efficiency is low, and the clamping stability is poor. Therefore, we have developed an anchor rod processing fixture.
