[0022] The adjusting mechanism 4 includes a sliding rod 401, a right water-passing portion 406 and a rack 404. A sliding rod 401 that can slide left and right is vertically arranged in the protective shell 2, and the right water-passing portion 406 is arranged on the sliding rod 401. One end of the tested pipe can be fixed to the right water-passing portion 406 by a clamp. A U-shaped plate 402 is fixed to the lower end of the sliding rod 401, and a rotatable gear 403 is horizontally arranged on the inner side of the U-shaped plate 402. A first motor 405 for driving the gear 403 to rotate is fixedly installed on the U-shaped plate 402, and a rack 404 meshing with the gear 403 is fixed in the bottom box 1.

[0023] The device starts the first motor 405, which drives the gear 403 to rotate, and then the gear 403 engages the rack 404, and then the gear 403 drives the gear 403 to move to the left, thereby adjusting the distance between the right water inlet and the left water inlet.

[0024] A sliding groove is provided at the inner bottom of the protective shell 2 , and the sliding rod 401 is slidably connected to the sliding groove, thereby increasing the stability of the sliding rod 401 when moving.

[0025] See also Figure 1 and Figure 5 The lifting mechanism 5 in this embodiment includes a limit rod 501, a third motor 507 and a protective box 509. Two groups of limit rods 501 are vertically arranged in the protective shell 2, and each group of limit rods 501 has two limit rods. The limit rods 501 are slidably installed with a liftable fixed box 502. The protective shell is fixedly installed with a protective box 509. A rotating connecting winch 508 is horizontally arranged in the protective box 509. A rope 510 is wound around the connecting winch 508. The third motor 507 for driving the connecting winch 508 to rotate is fixedly installed on the protective box 509, and one end of the rope 510 is fixed to one side of the fixed box 502.

[0026] The device starts the third motor 507, which drives the connecting winch 508 to rotate, and then the connecting winch 508 pulls the rope 510, and then the rope 510 pulls the fixed box 502 up, thereby adjusting the height of the fixed box 502.

[0027] Among them, a second motor 504 is horizontally arranged in the fixed box 502, and a rotating block 503 is fixed to the output end of the second motor 504. A sleeve 506 is connected to one side of the rotating block 503. The pipe fitting is sleeved on and fixed to one end of the opening of the sleeve 506 through a clamp. The upper end of the sleeve 506 is connected to a water inlet pipe 505. The water inlet pipe 505 can pass a fluid with a certain pressure or temperature into the sleeve 506 from the outside, and then enter the test pipe fitting from the sleeve 506. A left water passing part is provided on the sleeve 506, and the other end of the tested pipe fitting can be fixed to the left water passing part by a clamp. The left water passing part and the right water passing part 406 can be used to pass or discharge a fluid with a certain temperature or water pressure into the pipe fitting.

[0028] The working principle of the above embodiment is:

[0029] When it is necessary to adjust the distance between the left water-passing part and the right water-passing part 406, the first motor 405 is started, and the first motor 405 drives the gear 403 to rotate, and then the gear 403 engages the rack 404, and then the gear 403 drives it to move to the left or to the right, thereby adjusting the distance between the right water inlet part and the left water inlet part, and adjusting it to the appropriate distance.

[0030] One end of the tested pipe can be fixed to the left water passage part by a clamp, and the other end can be fixed to the right water passage part 406 by a clamp, and then liquid is poured into the water inlet pipe 505 and the sleeve 506 from the outside, and then enters the test pipe from the sleeve 506.

[0031] At this time, by starting the second motor 504, the second motor 504 drives the rotating block 503 to rotate, and the rotating block 503 drives the sleeve 506 to rotate, and then the sleeve 506 drives the test pipe to rotate, while the other end of the pipe remains fixed, so that the rotating end of the pipe can be twisted to achieve fatigue resistance testing.
