[0024] Combined with attachment Figure 1 -Attached Figure 9 , further comprising an adjustment assembly 8 for changing the angle of the fixing plate, so that the part to be tested can change its tilt angle during the experiment, thereby increasing the contact area of the part during the experiment and improving the accuracy of the experimental results; the adjustment assembly 8 includes a driven rod 801, and the right end of the driven rod 801 penetrates the inside of the rightmost adjustment block 5 and the rectangular frame 3, and the left end of the driven rod 801 is inserted into the inside of the circular hole 7011. By providing the driven rod 801, the driven rod 801 can rotate synchronously with the circular rod 701 when the circular rod 701 rotates; Among them, two groups of limit blocks 8011 are symmetrically installed on the surface of the driven rod 801, and the limit blocks 8011 slide in cooperation with the inner wall of the limit groove 7012. By setting the limit blocks 8011, the driven rod 801 can slide normally inside the circular hole 7011. At the same time, when the circular rod 701 rotates, the limit blocks 8011 and the limit groove 7012 cooperate with each other to drive the driven rod 801 to rotate.

[0025] Among them, the right end of the driven rod 801 is fixedly installed with a pulley group 802. By setting the pulley group 802, when the driven rod 801 rotates, the pulley group 802 can be driven to rotate synchronously; the other end of the pulley group 802 is fixedly connected to a screw rod 803. By setting the screw rod 803, it can rotate synchronously with the pulley group 802; the screw rod 803 is located just below the partition plate 2, and the screw rod 803 is rotatably connected to the inner wall of the test box body 1. The surface of the screw rod 803 is engaged with two sets of symmetrically arranged moving blocks. 804, the two sets of moving blocks 804 are fixedly connected by a connecting rod, and the moving block 804 is slidably matched with the inner wall of the test box body 1 through a slider. By setting the moving block 804, it can move laterally when the screw rod 803 rotates; it is worth noting that a bar block is provided at the lower end of the moving block 804, and a ring is rotatably connected inside the bar block, and the ring is elastically engaged with the bar block in the initial state, and the ring is meshed with the screw rod 803, so that when the moving block 804 cannot move, the screw rod 803 will start to drive the ring to rotate alone; Among them, the opposite surfaces of the two groups of moving blocks 804 are provided with inclined surfaces 805, and the surfaces of the inclined surfaces 805 are slidably matched with matching blocks 806. By setting the inclined surfaces 805 and the matching blocks 806, when the moving block 804 moves, the matching blocks 806 are controlled to change their positions accordingly; that is, the matching block 806 on the left side will drop when the moving block 804 moves horizontally, and the matching block 806 on the right side will move upward under the squeezing of the inclined surfaces 805; the upper end of the matching block 806 is fixedly installed with a connecting rod 807, the upper end of the connecting rod 807 penetrates the partition plate 2 and extends to the bottom of the fixed plate, the upper end of the connecting rod 807 is movably connected to the lower surface of the fixed plate, and by setting the connecting rod 807, it can play a guiding and limiting role, and at the same time cooperate with the matching block 806 to make the fixed plate tilt.

[0026] Specifically, when conducting an experiment on a part, the part is placed on the surface of the fixed plate and fixed, and then the experimental environment is selected as needed, and the conversion handle 702 is started to rotate, so that the round rod 701 rotates and drives the adjustment block 5 on the left to start rotating. During the rotation of the round rod 701, the driven rod 801 is driven to rotate synchronously, so that the pulley group 802 starts to drive the screw rod 803 to rotate synchronously. The rotating screw rod 803 drives the surface-engaged moving block 804 to move horizontally, so that one group of the two connecting rods 807 moves downward and the other group moves upward, thereby changing the inclination angle of the part, increasing the contact area of the part, and improving the accuracy of the detection result. When it is necessary to carry out multiple experimental environments at the same time or to enhance the experimental intensity under the same environment, by pressing the conversion handle 702, the round rod 701 is driven to move to the right, so that the installation groove 703 on the left is separated from the groove 501 on the left, and the installation groove 703 in the middle position begins to engage with the groove 501 in the middle position, and then the conversion handle 702 is rotated again to make the adjustment block 5 in the middle position start to rotate. When it is rotated to the required experimental module 6, the rotation is stopped, and the conversion handle 702 is pressed again to make the installation groove 703 in the middle begin to separate from the groove 501, and the installation groove 703 on the right begins to engage with the groove 501 on the right, and the purpose of adjusting the right position adjustment block 5 is started, thereby achieving the purpose of carrying out multiple groups of experimental environments at the same time, and at the same time, it can also realize detection of different intensities under the same experimental environment, increase the practicality of the device, and ensure the accuracy of the detection results.
