[0027] The working principle of the present utility model:

[0028] When it is necessary to replace the metal material for tensile testing, first remove the two pins 12 inside the two clamping blocks 11 and the two mating blocks 9, so that the baffle 10 can move forward, making the baffle 10 disengage from the two front columns 1d.

When it is necessary to draw out the collection box 301, pull the pull rod 502 downward to move the positioning block 501 downward, so that the positioning block 501 is removed from the inside of the collection box 301. At this time, the pull block 302 can be pulled forward to move the collection box 301 and the four moving columns 303 forward, so that the collection box 301 is removed from the inside of the connecting block 1b and the connecting base 1a, thus drawing out the collection box 301. When the pull block 302 moves downward, the two return springs 503 will deform. After the collection box 301 is inserted and connected to the connecting block 1b, release the pull block 302. Under the elastic action of the two return springs 503, the pull rod 502 drives the positioning block 501 to rebound into the inside of the collection box 301 to realize the fixation of the collection box 301.
