A trigger linkage mechanism for use in toy gun includes: a trigger pivoted to a gun frame and formed with a push block; a linkage member having one end formed with a first pivotal part and the other end formed with a second pivotal part. The linkage member is formed with an abutting part disposed between the two pivotal parts and abutted against the push block; a pull member pivoted to the second pivotal part and formed with a pawl part capable of being correspondingly buckled with the buckle part; a first recovery spring clamped between the gun frame and the linkage member; and a second recovery spring clamped between the linkage member and the pull member. Accordingly, the rotation radian and speed of the pawl part is able to be controlled and adjusted.
