[0034] In the present embodiment, a concave surface 321 is formed on the surface of the two clamping jaws 32 facing the water nozzle. The shape of the concave surface 321 is the same as the shape of the outer peripheral wall of the water nozzle, which can better fit the outer peripheral wall of the water nozzle, so that the clamping jaws 32 can better clamp the water nozzle and prevent the water nozzle from falling off during the test, causing the test to be interrupted.

[0035] In the embodiment of the present invention, the testing machine 100 further includes two silicone sheets 322 , and one silicone sheet 322 is disposed on a concave surface 321 .

One limit switch 7 is arranged above one end where the extractable water spout 4 is installed, and is used to mark the starting point, that is, the position of 0 mm from the starting point, and the other limit switch is arranged at one end away from the starting point. During the life test, the clamp assembly 3 always maintains the first state, clamps the water spout, and the drive assembly 2 drives the clamp assembly 3 to move away from the extractable water spout 4. When the slider touches the limit switch 7 away from the extractable water spout 4, the movement direction of the drive assembly 2 is switched, and the drive assembly 2 drives the clamp assembly 3 to move toward the extractable water spout 4. When the slider touches the limit switch 7 above the extractable water spout 4, the movement direction of the drive assembly 2 is switched again, and the above steps are repeated many times until the number of tests is completed. During the fallback test, the clamp assembly 3 first clamps the water spout, and the driving assembly 2 drives the clamp assembly 3 in the first state to move away from the pull-out water spout 4. When the slider touches the limit switch 7 away from the pull-out water spout 4, the clamp assembly 3 is controlled to switch to the second state to release the water spout, and the water spout is automatically retracted under the action of the counterweight block. After waiting for a period of time, the driving assembly 2 is controlled to drive the clamp assembly 3 to move towards the pull-out water spout 4. When the slider touches the limit switch 7 above the pull-out water spout 4, the clamp assembly 3 is controlled to switch to the first state to clamp the water spout, and the movement direction of the driving assembly 2 is switched again. The above steps are repeated many times until the test times are completed.
