[0024] The effect achieved by the entire embodiment 1 is that when it is necessary to detect the shrinkage and expansion of concrete, the concrete to be mixed can be poured into the mixing barrel 301 first, and then water is added to the mixing barrel 301 according to the proportion, and the shrinkage function of the electric push rod 302 can be turned on, so that the two sets of electric push rods 302 simultaneously drive the barrel cover 304 to move downward through the connecting rod 303 until the stirring rod 306 is completely inserted into the mixing barrel 301. At this time, the motor 305 can be turned on by the control switch, so that the motor 305 drives the stirring rod 306 through the output end to stir the concrete in the mixing barrel 301.
