The rest of the structure is the same as that of embodiment 2.

Referring to fig. 1 to 9, before the device is used, the supporting member 102b on the upper side plate surface of the bearing plate 102a is adjusted according to the length and diameter of the metal segment block to be tested, that is, the cross angle of the cross rod 102b-2 is adjusted by controlling the length change of the telescopic member 102b-4, so as to meet the requirement of placing the metal segment block to be tested, and the metal segment block can be completely supported and cannot fall off between the two rollers G; secondly, the length of the clamping end of the clamping rod 202c extending out of the through hole 202a-1 is adjusted by adjusting the position of the limiting ring 202c-1 according to the length of the metal segment block to be measured.

At this time, the supporting member 102b is located at the highest position, and both sides are not blocked by the clamping unit 200, which is very convenient for placing the metal segment block to be measured.

When the metal section block is placed between the two parallel rollers G, under the action of the gravity of the metal section block and the control of the contraction of the jacking oil cylinder D, the bearing plate 102a and the metal section block gradually descend, and at the moment, the deflection block 201b and the balance piece 102c gradually return to the initial state; when the clamping end of the clamping rod 202c contacts with the end of the metal segment block, the clamping rod 202c is gradually and reversely pressed along with the continuous descending process, the elastic member 202b is compressed in the through hole 202a-1, and the clamping rods 202c on the two sides can stably clamp the two sides of the metal segment block to be tested.

And after the metal processing procedure is finished, the metal section block needs to be taken out, at the moment, the jacking oil cylinder D is controlled to lift, the step before clamping is repeated, the metal section block can be lifted to the highest position of the device, and the metal section block is convenient to take out.
