A sliding tube 3011 is threadedly installed on the outer wall of the threaded rod 309. A connecting screw 3012 is installed at the top of the sliding tube 3011.

[0027] In this embodiment, as Figure 2 shown, the tensile force sensing assembly 1 includes a tensile force sensor 101. A display control host 102 is installed on one side of the tensile force sensor 101; when calibrating the force measuring rod through the tensile force sensor 101, the change of the tensile force can be sensed, and the display control host 102 displays the tensile force value, etc., for control, and calibration can be performed according to the numerical change and the numerical change of the force measuring rod.

[0028] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, screws are provided at both the top and bottom of the tensile force sensor 101, and the first internally threaded tube 201 is threadedly installed on the outer wall of the screw, and grid-shaped anti-slip patterns are provided at both the front and rear ends of the mounting block 202; the second internally threaded tube 301 is threadedly installed on the outer wall of the screw at the top of the tensile force sensor 101. When the mounting blocks 202 on the first mounting assembly 2 and the second mounting assembly 4 are installed with the clamping structure on the pull rod, the grid-shaped anti-slip patterns on the mounting blocks 202 of the first mounting assembly 2 and the second mounting assembly 4 can improve the stability of the installation with the clamping structure on the force measuring rod.

[0030] In this embodiment, as Figure 4 and Figure 5As shown, the worm 304 is meshed and installed with the worm wheel 307, and the first bevel gear 308 is meshed and installed with the second bevel gear 3010. The worm wheel 307 and the worm 304 form a worm drive mechanism, and the first bevel gear 308 and the second bevel gear 3010 form a gear drive mechanism. Moreover, the threaded rod 309 and the sliding tube 3011 form a screw drive mechanism. When the anti-slip knob 305 is rotated, it drives the worm 304 to rotate. The rotation of the worm 304 drives the worm wheel 307, the connecting rod 306, and the first bevel gear 308 to rotate.

Then, a force-measuring pull rod is used for testing. Next, the anti-slip knob 305 is rotated to drive the worm 304 to rotate. The rotation of the worm 304 drives the worm wheel 307, the connecting rod 306, the first bevel gear 308, the second bevel gear 3010, and the threaded rod 309 to rotate. At the same time, it drives the sliding tube 3011, the connecting screw 3012, and the second mounting component 4 to move up and down, adjusting the calibration device to an appropriate length.
