AI Technical Summary
Existing mechanical experimental devices cannot pull experimental materials at a uniform speed and synchronously, resulting in uneven plastic deformation, which can easily cause cracks and pose a danger to students.
The design employs a bidirectional screw, a movable seat, a slide bar, and a clamping assembly to achieve synchronous clamping and buffering at both ends of the experimental material, preventing deformation and absorbing impact energy.
This improves the precision and safety of mechanical experiments, ensuring that experimental materials do not deform and protecting student safety.
