A collision avoidance device for a moving part according to claim 1, wherein: when interference is generated between the first movement mechanism part (2) and the second movement mechanism part (4) to approach, the brake switch trigger assembly (6) contacts the emergency stop brake switch (3) on the second movement mechanism part (4) at the first time, emergency braking is realized through the triggering of the emergency stop brake switch (3), under the influence of inertia, the first movement mechanism part (2) and the second movement mechanism part (4) still approach to each other continuously, at the moment, the extrusion force acting on the braking distance extending arm (1) between the first movement mechanism part (2) and the second movement mechanism part (4) is increased, and when the extrusion force is greater than the resultant force of the braking distance jacking teeth (517) and the jacking teeth between the braking distance jacking teeth (517) and the braking distance positioning teeth block (512), the tooth disengaging phenomenon is generated between the braking distance jacking teeth (517) and the braking distance positioning teeth block (512), therefore, the extension length of the braking distance extension arm (1) is compressed and shortened rapidly, or the braking distance jacking tooth (517) and the braking distance positioning tooth block (512) are not disengaged from each other, the braking distance jacking tooth (517) slides on the vertical base guide sliding rod (504) along with the braking distance positioning tooth block (512), the compression of the length of the braking extension arm unit is realized, and the extrusion damage to the braking distance extension arm (1), the braking switch trigger assembly (6) and the braking distance adjusting base assembly (5) when the first movement mechanism component (2) and the second movement mechanism component (4) are close to each other is avoided.
6. A collision avoidance device for a moving part according to claim 1, wherein: the braking distance adjusting base assembly (5) is fixed on the first movement mechanism component (2) through a mounting screw hole (518) and a fastening bolt on a mounting chassis (503).
