[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model involves manually pulling the adjusting rod upwards to disengage it from the adjusting hole, simultaneously stretching the adjusting spring. Then, the T-shaped bar is pushed to one side, adjusting hook two to a suitable position. The adjusting rod is then released, allowing it to be inserted into another adjusting hole under the restoring force of the adjusting spring, thus limiting the T-shaped bar. The two ends of the torsion bar spring are then hooked onto hook two and hook one, respectively. The controller starts the motor, causing its output shaft to rotate the lead screw. This allows the E-shaped plate to move to one side along the outer surface of the lead screw, simultaneously moving the T-shaped bar, the tension detector, and hook two to one side. The tension detector monitors the tension of the torsion bar spring. The force is detected when the electromagnet is in the open state, generating a magnetic force on the movable rod, keeping it relatively fixed. When the shorter torsion spring has finished its force detection, the controller controls the corresponding electromagnet to close, causing the magnetic force on the movable rod to disappear. At this point, under the reset force of the torsion spring, the hook and the movable rod move to one side, simultaneously compressing the buffer spring. The reset force of the buffer spring provides a certain buffering effect. Other longer torsion springs can continue to be tested for force. In this way, multiple torsion springs of different lengths can be tested for force at once, thereby improving the efficiency of torsion spring force detection.

[0016] 2. This utility model, by rotating the first and second protective frames downwards and, with the cooperation of the slider and the groove, allows the second protective frame to slide a suitable distance along the outer surface of the first protective frame, moving the limiting rod to the position of the limiting hole. By pulling the limiting rod upwards a suitable distance, the limiting spring is stretched. Then, the limiting rod is released, allowing it to be inserted into the limiting hole under the restoring force of the limiting spring, thus connecting the fixed frame, the second protective frame, and the first protective frame together. In this way, when the torsion bar spring is subjected to tensile testing, it can be protected by the fixed frame, the second protective frame, and the first protective frame, preventing the torsion bar spring from breaking and falling off during the tensile testing process, which could cause injury to surrounding instruments or testing personnel, thereby improving the safety of torsion bar spring tensile testing.
