[0002] As the layout of electronic and electrical equipment inside the high-speed train is very tight, which greatly compresses the space, the connecting cables of the electronic and electrical equipment inside the high-speed train are usually laid out in cable troughs to uniformly plan and arrange the cables.

[0003] In the production and processing of high-speed rail ducts, in order to install them more conveniently, it is usually necessary to use a hole-opening device to pre-open holes in the duct body to facilitate subsequent installation and fixing work. However, most of the existing hole-opening devices for ducts are single-hole opening methods, and can only open holes in one group of duct body sides of the duct at a time. The duct orientation needs to be frequently flipped before opening holes in all orientations. The operation is cumbersome and the hole-opening is time-consuming, which is not conducive to the modular and continuous hole-opening work of the duct. To this end, those skilled in the art provide a high-speed rail duct duct body hole-opening device to solve the problems raised in the above background technology. Utility Model Content
