[0025] The working principle of this utility model is as follows: In use, first, the spiral hose 5 is sleeved on the round rod 102, and then moved to the second support plate 417 and the first support plate 408. One end of the spiral hose 5 extends out from the side of the second support plate 417. Then, the electric cylinder 412 is activated, and the electric cylinder 412 drives the pressure plate 410 to descend. The pressure plate 410 presses the spiral hose 5 tightly, and the protrusion at the bottom of the pressure plate 410 is located to the left of the protrusion on the second support plate 417 and to the right of the protrusion on the first support plate 408.

[0026] Start the stretching motor 201, which drives the stretching double-ended lead screw 202 to rotate. The stretching double-ended lead screw 202 drives the stretching slider 1 203 and stretching slider 205 to move in opposite directions, thereby driving the clamping mechanism and the conveying mechanism to move in opposite directions. The protrusion on the support plate 2 417 on the support assembly drives the protrusion on the pressure plate 410 to move, thereby driving the pressure plate 410 and the pressure plate slider 411 to move.

[0027] When the connecting rod 416 contacts the fixed rod 414, the connecting rod 416 continues to move. The fixed rod 414 pushes the connecting rod 416 to rotate, and the connecting rod 416 drives the drive rod 418 and the feeding slide plate 401 to move. The feeding slide plate 401 drives the support plate 417 to move, thereby conveying one end of the spiral hose 5 to the clamping mechanism on the stretching slider 203. The pressure plate 410 in the pressing assembly rises, starting the clamping motor 302. The clamping motor 302 drives the clamping slider 305 to move in opposite directions. The clamping slider 305 clamps one end of the spiral hose 5, and the pressure plate 41... The pressure plate 410 is lowered until the bottom of the protrusion is lower than the top of the protrusion on the support plate 417. Then the tension motor 201 rotates in the opposite direction, driving the tension slider 1 203 and the tension slider 2 205 to move in opposite directions. When the unclamped end of the spiral hose 5 moves between the clamping sliders 305 on the tension slider 2 205, the other end of the spiral hose 5 is clamped by the two clamping sliders 305. Then the tension slider 1 203 and the tension slider 2 205 continue to move in opposite directions to perform a tensile yield test on the spiral hose 5.
