[0033] In the above, the rocker 31 drives the bidirectional threaded rod 332 connected thereto to rotate, when the bidirectional threaded rod 332 rotates, the two threaded blocks 331 move towards each other due to the threaded connection relationship, when the threaded blocks 331 move, the connecting rods 334 rotationally connected to the lower ends of the threaded blocks 331 move, the connecting rods 334 drive the rectangular plate 335 to move towards the side of the placing rack 1, and the rectangular plate 335 clamps and fixes the sample placed on the placing rack 1;

[0034] In the above, when the rocker 31 drives the bidirectional threaded rod 332 connected thereto to rotate, power is transmitted to the bevel gear set 34 connected thereto, the input end of the bevel gear set 34 rotates, power is then transmitted to the transmission rod 35 connected to the output end, the transmission rod 35 rotates, power is then sequentially transmitted to the bevel gear set 34 located at the right portion, the bevel gear set 34 located at the right portion drives the bidirectional threaded rod 332 located at the right portion to rotate, and the bidirectional threaded rod 332 located at the right portion drives the bidirectional threaded rod 332 located at the left portion to rotate, so that the rotation of the rocker 31 drives the pressing mechanisms 33 located at the left portion and the right portion to simultaneously descend and clamp and fix the sample placed on the placing rack 1.

[0035] Further, in order to achieve the purpose that the pressure testing device 4 slides in the inner cavity of the sliding shell mechanism 5, referring to Figure 4 The sliding shell mechanism 5 comprises a rectangular shell 51, the rectangular shell 51 is fixedly connected to the upper end of the front portion of the placing rack 1, the top wall of the rectangular shell 51 is fixedly connected with the slide rod 52 at the middle side of the rear portion, and the left wall and the right wall of the rectangular shell 51 are both provided with the slide groove one 53 at the rear portion.
