The inner walls of the two L-shaped fixing plates 28 are respectively fixedly connected with fixing screws 29. The L-shaped fixing plates 28 are fixed to the fixing frame 1 through the fixing screws 29. The top of the inner walls on both sides are fixedly connected, and one side of the two L-shaped fixing plates 28 is respectively fixedly connected to the second servo motor 10, and the transmission end on one side of the second servo motor 10 is fixedly connected to the transmission shaft 21, and one end of the transmission shaft 21 is fixedly connected to the transmission gear 21. The side surfaces of the transmission gear 21 are respectively connected to the transmission rack 21 through meshing activities. In the process of movement, the spring 17 can be pressed down by the sliding block 18. Similarly, starting the second servo motor 10 drives the transmission shaft 21 to rotate, and at the same time, the transmission gear 21 is driven to rotate by the transmission shaft 21. Since the transmission gear 21 is meshed with the transmission rack 213, when the transmission gear 21 rotates, it drives the upper moving frame 21 to move upward.

At the same time, when using it, first start the first servo motor 4 to drive the transmission shaft 15 to rotate, and at the same time, the transmission shaft 15 drives the transmission gear 16 to rotate. Since the transmission gear 16 is engaged with the transmission rack 17, when the transmission gear 16 rotates, it can prompt the lower moving frame 14 to move downward, and during the movement, the spring 1 can be pressed down by the sliding block 18. 7. Similarly, start the second servo motor 10 to drive the transmission shaft 2 11 to rotate, and at the same time drive the transmission gear 2 12 to rotate through the transmission shaft 2 11. Since the transmission gear 2 12 is engaged with the transmission rack 2 13, when the transmission gear 2 12 rotates, it drives the upper moving frame 21 to move upward. At the same time, during the movement, the spring 17 can be pressed down by the sliding block 18, thereby ensuring that the lower moving frame 14 and the upper moving frame 21 move in opposite directions, stretching the steel bars that need to be tested inside, thereby testing the strength of the steel bar joints, which can effectively prevent the steel bars from breaking and the steel bar slag from splashing during the stretching of the steel bar joints, and is safer and more practical.
