The force applying assembly 20 is vertically arranged on the support frame 11 and is in sliding connection with the support frame 11. The output end of the force applying assembly 20 is located below the workbench 12. The rotating wheel assembly 30 is rotatably connected to one side of the force applying assembly 20 and is arranged perpendicularly to the force applying assembly 20. By rotating the rotating wheel assembly 30, the output end of the force applying assembly 20 is driven to move upward or downward relative to the workbench 12, thereby moving closer to or away from the heat sink. The measuring mechanism comprises a detection ruler assembly 40 and a force sensing assembly 50. The detection ruler assembly 40 is arranged between the support frame 11 and the force applying assembly 20 for observing the displacement stroke of the force applying assembly 20.

The four groups of support columns are circumferentially arranged between the support plate and the base 10, and the two ends of each group of support columns are fixedly connected to the four corners of the support plate and the base 10, respectively. The support frame 11 in the form of a frame structure composed of the support plate and the four groups of support columns facilitates the installation and disassembly of various components inside the support frame 11, and facilitates subsequent maintenance and maintenance.

[0033] The force sensing assembly 50 is arranged to accurately monitor the applied force of the force applying assembly 20.

At the same time, by arranging the display screen 52, the current applied force can be displayed instantly, so that the operator can intuitively and accurately monitor and adjust the force, ensuring the accuracy and consistency of the applied force during the test process.

[0035] Preferably, the detection ruler assembly 40 comprises a ruler 41. The ruler 41 is vertically arranged on one side of the support frame 11 and is arranged in parallel with the output end of the force applying assembly 20. The movable block is movably connected to the ruler 41, and the movable block and the force applying assembly 20 are connected through the detection connecting plate. By arranging the detection ruler assembly 40, the operator can directly observe the moving position of the force applying assembly 20 according to the relative movement stroke of the movable block and the ruler 41, so that the operator can intuitively understand the force applying process.

[0036] Further, the movable block is provided with a digital display instrument 43 for displaying the movement stroke.

At the same time, the force sensing assembly 50 is located between the force applying rod 24 and the mounting seat 25, which can accurately measure the size of the applied force, facilitating the operator to penetrate the size of the applied force, and avoiding the problems of damage to the radiator due to excessive applied force or inaccurate test due to insufficient applied force.

[0043] Still further, the mounting seat 25 has an "L" shape structure, and guide rails 251 are arranged between the two ends of the mounting seat 25 and the side plate 21. By arranging the guide rails 251, the stability and accuracy of the force applying rod 24 during movement are ensured, and test errors caused by shaking or deviation are avoided.

[0044] Preferably, the rotating wheel assembly 30 comprises a fixed seat 31, a rotating wheel 32 and a connecting rod 33.
