The utility model discloses a launching device and a launching toy, the launching device comprises a launcher and a main body, the launcher is suitable for an object to be launched to be installed on the launcher, the launcher comprises an acceleration mechanism and a launching mechanism, the main body is detachably connected with the launcher, the main body comprises a sliding block and a releasing mechanism, the sliding block can move in a reciprocating mode, and the releasing mechanism can release the object to be launched. The sliding block is suitable for driving the acceleration mechanism so that the acceleration mechanism can drive the to-be-launched object to rotate, and the releasing mechanism is suitable for driving the launching mechanism so that the launching mechanism can drive the to-be-launched object to be launched. According to the technical scheme, the sliding block can drive the to-be-launched object to rotate, the releasing mechanism can drive the to-be-launched object to be launched, the sliding block and the releasing mechanism do not affect each other, the to-be-launched object can still keep the rotating state after being launched, competitive confrontation is particularly facilitated, and playability and interestingness are improved.
