[0038] Then control the telescopic rod 4001 built-in fixed block 4 to fix the mounting plate 5, and then control the linear driver built-in detector 16 to operate to drive the impact head 17 to move, push the cylindrical test material 001 fixed by the second limiting block 11 and the second limiting plate 12 through the impact head 17 on the detector 16 below, and drive the limiting cylinder 6, the connecting plate 10, the second limiting block 11 and the second limiting plate 12 to move upwards. The limiting cylinder 6 drives the components connected thereto to move upwards, while controlling the first electric push rod 7 to operate to retract to drive the first limiting block 8 and the first limiting plate 9 to move downwards. Then, in cooperation with the detector 16 and the impact head 17, further pushing is performed to make the upper end of the limiting cylinder 6 adhere to the lower side surface of the two third limiting plates 14. Then, control the first electric push rod 7 to push the first limiting block 8 to move upwards.
