Brake device of two-for-one twister

The utility model belongs to the field of two-for-one twisters, particularly relates to a brake device of a two-for-one twister, and aims to solve the problems that a brake pad cannot be well adsorbed and fixed under the condition of power failure in the braking process, only the brake pad on one side is used for braking, and the braking distance is relatively long. Two sliding frames are arranged on one side of the mounting plate, mounting assemblies for sliding clamping are arranged in the sliding frames, two brake blocks are arranged on one side of the mounting plate, and a driving assembly for driving the two brake blocks to be close to each other is arranged in the mounting plate. And meanwhile, the clamping columns are matched to limit the brake blocks and prevent the brake blocks from sliding, the two brake blocks can be driven to get close to each other to achieve the braking effect through pushing of the output shaft of the electric push rod, abrasion of the brake blocks can be reduced, and the braki
