The slider 35 can squeeze the second spring 34 to retract, so that the slider 35 can be locked together with the connecting block 38 to ensure the reliability between the instrument body 1 and the connecting pipe 31.

[0036] Working principle: First, the sealing gasket 28 is inserted into the instrument body 1. Then, pressing the sealing plate 21 allows it to engage with the instrument body 1. At the same time, the ball head block 25 is squeezed by the connecting bracket 26. Afterward, the ball head block 25 is compressed by the moving plate 24 pressing the spring 23, allowing the ball head block 25 to engage with the slot 27, thus completing the installation of the sealing plate 21. The sealing plate 21 and the sealing gasket 28 can ensure the sealing of the instrument body 1 to prevent water leakage.

[0037] Then, the instrument body 1 and the connecting pipe 31 can be screwed together using threads. At the same time, the connecting block 38 will squeeze the slider 35 to retract, so that the slider 35 can slide on one side of the L-shaped frame 32 through the slide rod 33. The slider 35 can squeeze the second spring 34 to retract, so that the slider 35 can be locked together with the connecting block 38 to ensure the reliability between the instrument body 1 and the connecting pipe 31.
