[0017] The work surface 5 provides a solid and stable platform for installing and supporting subsequent components.
[0018] The buffer guide post 12 is installed on the work surface 5. The buffer guide post 12 is used to absorb and reduce the impact of external vibration or shock on the system, protect the precision equipment from unnecessary interference, and thus ensure the accuracy and repeatability of the test results.
[0019] The secondary support plate 4 is connected to the work surface 5 through the buffer guide column 12.

Through slight adjustments, it can ensure that the workpiece placement plate 3 is in a completely horizontal state. The pads 7 can also disperse the load and protect the workpiece placement plate 3 from being affected by excessive local pressure.
[0021] The workpiece placement plate 3 is a core platform for placing the sample to be tested. The workpiece placement plate 3 is easy to install and fix the sample, and can maintain the invariance of the sample position during the test process to ensure the consistency and reliability of the test results.

[0023] The sliding guide groove 2 is arranged on the workpiece placement plate 3, and is used to guide and limit the smooth sliding of the workpiece mounting frame 1 in the horizontal direction; the position in the horizontal direction can be easily adjusted, thereby improving the flexibility and application scope of the test.
[0024] The workpiece mounting frame 1 is a key component that directly carries the specimen and allows the specimen to be accurately positioned in three-dimensional space. It simplifies the specimen loading process and ensures that the specimen is stably fixed during the entire test period.
[0025] The lead screw swivel seat and the lead screw displacement group adjust the distance of the workpiece mounting frame 1 by driving the lead screw to rotate through a motor.
[0026] The limit group provides physical resistance when sliding to extreme positions, preventing excessive sliding or collision, protecting the equipment from damage. It also helps users quickly find and lock the ideal workpiece position during the adjustment process, ensuring efficient and safe test preparation.

[0032] The lead screw mounting seat 11 and the intermediate adapter sleeve 10 are installed at both ends of the lead screw 14 and the second lead screw 13, and play the role of fixing the lead screw and transmitting torque, thereby ensuring the stability of the lead screw when rotating.
[0033] The intermediate adapter sleeve 10 connects the first lead screw 14 and the second lead screw 13 so that the two can rotate synchronously but in opposite directions; it can realize the same and reverse movement of the two workpiece mounting frames 1, improve the precise controllability of the movement, and the opposite rotation direction helps to balance the force, reduce system vibration, and can also reduce the tilt or deflection problem caused by a single lead screw, further improving the stability of positioning.

The clamping action is implemented by rotating or pushing and pulling the clamping shaft 17 to prevent it from accidentally moving due to external force or inertia during the test. The clamping shaft 17 usually allows quick release to facilitate re-testing or replacing the sample after adjustment, which improves the practicality and work efficiency of the equipment.
[0037] Furthermore, the workpiece mounting frame 1 is an arched structure, on which connecting guide holes for placing samples are provided.
