The invention provides a quick-response linked target system and relates to a KL-II type quick-response linked target system, belonging to shooting practice equipment characterized by pure mechanical linked action. Targets in the system can be used for separate shooting practice and linked shooting practice, namely precision shooting practice and quick linked shooting practice; and the accurate judgment capability and quick-response capability of trainers can be improved during practice. Moreover, the system has a better ornamental value and is suitable for various exercises and performance occasions. The system comprises an up/down type steel plate head target, a short-distance running target, a swing target, a quick double-click target and a trigger mechanism. The system is of a pure mechanical structure; and when the system is in a linked state, all the targets share the same trigger mechanism; except that the up/down steel plate head target serves as the first target, the short-distance running target, the swing target and the quick double-click target can be used as different modules; and according to the shooting demands, the positions and triggering sequences of all the targets can be combined at random or each target can be regarded as an independent unit and separated from the system to be used for separate specialized training.
