When the double-headed motor 203 rotates in the opposite direction, the two driving screw rods 204 drive the two rectangular sliders 202 to move inward at the same time; when the two driving screw rods 204 drive the two rectangular sliders 202 to move inward at the same time, the two rectangular sliders 202 are automatically separated from the two first switches 206; when the two driving screw rods 204 drive the two rectangular sliders 202 to move inward at the same time, the two movable clamping frames 402 are automatically reset under the action of the four supporting springs 405; when the two driving screw rods 204 drive the two rectangular sliders 202 to move inward at the same time, the eight rectangular guide rods 304 are automatically reset, which facilitates the rapid separation of the eight semicircular clamping blocks 305 from the hose to be tested, thereby improving the disassembly efficiency of the hose after the test; when the two driving screw rods 204 drive the two rectangular sliders 202 to move inward at the same time, the two pressing plates 406 are automatically separated from the two control buttons 407, thereby realizing the automatic stop of the test.
