Then start the motor 9 through the external controller. The output end of the motor 9 drives the first pulley 10 and the gear 11 to rotate. The gear 11 can drive the two racks 12 on both sides to move in opposite directions through the meshing relationship, thereby driving the corresponding moving frames 3 to move away from each other on both sides. Then drive the clamping blocks 4 to move and pull on both sides through the moving frames 3 to perform a ductility test on the alloy body 20. And during the rotation of the first pulley 10, it can drive the corresponding second pulley 13 and the lead screw 15 to rotate through the two transmission belts 14, so that the lead screw 15 drives the lifting plate 7 to move downward under the limitation of the limiting rod 16 through the threaded connection relationship.

Then start the motor 9 through the external controller. The output end of the motor 9 drives the first pulley 10 and the gear 11 to rotate. The gear 11 can drive the racks 12 on both sides to move in opposite directions through the meshing relationship, thereby driving the corresponding moving frames 3 to move away from each other. Then drive the clamping blocks 4 to move and pull in opposite directions through the moving frames 3 to perform the ductility detection on the alloy main body 20. And during the rotation of the first pulley 10, it can drive the corresponding second pulley 13 and the lead screw 15 to rotate through the two transmission belts 14, so that the lead screw 15 drives the lifting plate 7 to move downward under the limit of the limit rod 16 through the threaded connection relationship.
