At the same time, pulling the pulling plate 19 can make the protection plate 5 close and protect the extrusion plate 14 under the action of the first spring 16. The number of support columns 2 is multiple and evenly distributed in a rectangular array on the outer surface of the mounting base 1, so that the load test machine body 4 can be stably placed on the mounting base 1. The outer surface of the extrusion plate 14 is symmetrically provided with a first through-groove 25 The interior of the first through groove 25 is slidably connected to the outer surface of the protective plate 5, so that the extrusion plate 14 can slide inside the protective plate 5, and the outer surface of the square plate 6 is symmetrically provided with a second slide groove 7, and the interior of the second slide groove 7 is slidably connected with a slider 23.

[0020] Working principle: After the staff puts the test piece on the mounting base 1, the motor 22 can be started. The rotation of the output shaft of the motor 22 can drive the gear 24 to rotate. The rotation of the gear 24 can make the square plate 6 move on the support column 2. The movement of the square plate 6 drives the extrusion plate 14 to slowly approach the test piece and squeeze the limit. Then the staff turns off the motor 22 and pulls the pulling plate 19 at the same time, so that the pulling plate 19 moves upward inside the second through groove 21 and the U-shaped block 17. The movement of the pulling plate 19 drives the solid block 20 to move upward in the open groove 18 until it moves out of the open groove 18, so that the U-shaped block 17 is no longer fixed. Then, under the action of the first spring 16, the protective plate 5 moves in the extrusion plate 14 toward the middle of the mounting base 1, thereby closing the extrusion plate 14 to protect the test piece and prevent damage to the test piece from causing splashing and affecting the safety of the experimenter. Then the staff can start the load testing machine body 4 to work;

[0021] When placing test pieces of different heights, the staff can move the fixing plate 11 to make the fixing plate 11 move in the fourth slide groove 12 and squeeze the second spring 13. The second spring 13 is forced to contract, so that the fixing plate 11 slides out of the fixing groove 10. Then the staff can move the bracket 3 to make the bracket 3 slide inside the first slide groove 9 to adjust the height between the load testing machine body 4 and the mounting base 1. When it is adjusted to the appropriate height, the staff can release the hand that is moving the fixing plate 11. Under the action of the second spring 13, the fixing plate 11 enters the fixing groove 10 to fix the bracket 3, thereby improving the applicability of the device.
