[0003] For example, the patent number CN213871363U is a protective device for the water outlet of a farmland water conservancy pipeline, comprising a water outlet pipeline; a fixing piece is installed on the ground at the outer lower end of the water outlet pipeline, and the upper end face of the fixing piece is connected to a protective box body by bolts; a limiting mechanism is fixedly connected to the front side of the right end face of the protective box body, and the protective box body comprises a box door, a clamping block, a mesh frame and a desiccant. The above-mentioned documents still have deficiencies. When in use, since the length of an adult's palm is between 18 cm and 20 cm, the adult's palm just touches the lower end of the driving piece after bending upward, and since the length of a child's palm is much shorter than that of an adult, the box door is not easy to be opened by a child, which not only will not damage the valve on the water outlet, but also will not This causes a large amount of water waste, and the upper box door of the protection device can be opened without a key, thereby effectively avoiding unnecessary trouble caused by the loss of the key. However, the sizes of the semicircular holes arranged inside the first fixed base plate and the second fixed base plate in the above document are fixed. When fixing the pipe, only the pipe of one end size can be fixed, which is not convenient for fixing pipes of different sizes, thereby reducing the practicality of the protection device at the water outlet of the pipe. At the same time, a series of structural settings are used in the above document to prevent children from getting the key. However, if the key falls into the inside of the protective shell when an adult takes the key, it will be difficult to take it out, and the protective shell cannot be opened, which makes it inconvenient to open and close the protective door on the surface of the protective shell.
