The utility model provides an anti-trapping device applied to a distributed resistance-increasing tunneling machine and the tunneling machine, and the tunneling machine at least comprises a first resistance-increasing pipe (1) and a second resistance-increasing pipe (2) which are connected through a hydraulic cylinder (3); a plurality of resistance increasing blocks (11) are arranged in each resistance increasing pipe; the anti-trapping device comprises a guide pipe (4) and an anti-trapping rod (5); the guide pipe (4) penetrates through the pipe wall of the resistance increasing pipe and is peripherally fixed with the pipe wall; a boss is arranged at one end of the anti-trapping rod (5), and the size of the cross section of the boss is larger than the internal size of the cross section ofthe guide pipe (4); and the other end of the guide pipe (4) is sharp, can extend outwards from the guide pipe (4) and can be inserted into an outside rock-soil body. When the heading machine is trapped, the anti-trapping rods extending outwards from the resistance increasing pipes are inserted into a surrounding rock-soil body, the counter-acting force of the section can be increased, the pushingor pulling force provided for forward movement of the adjacent section pipes through the pushing or pulling action of the hydraulic cylinders annularly arranged in the positions between the adjacent pipes is improved, and forward movement of the adjacent section cylinders is facilitated.
