[0016] In order to make the technical means for realizing the utility model, creative features, objectives and effects easy to understand, the utility model is further explained below in conjunction with specific diagrams. In the description of the utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0017] Example

[0018] like Figure 1 and Figure 2 A cleaning gun head is shown, comprising a fixed head 1, a front end of a sand knife tube 2 is installed inside the fixed head 1, the rear end of the fixed head 1 is connected to an adapter 3, a fixed sleeve 4 is sleeved on the outside of the sand knife tube 2, the rear end of the sand knife tube 2 and the fixed sleeve 4 are installed inside the adapter 3, and the adapter 3 is connected to a gun head rod 5.

[0019] like Figure 2-Figure 4As shown, the front end of the adapter 3 is provided with a mounting cavity 6, and the mounting cavity 6 corresponds to the structure of the fixing sleeve 4. The fixing sleeve 4 is a truncated cone structure, and a strip hole 7 is opened on the outside of the fixing sleeve 4. The lower end of the fixing sleeve 4 is installed in the mounting cavity 6. The outer side of the mounting cavity 6 is provided with a thread and is threadedly connected with the fixed head 1. When the adapter 3 is connected to the fixed head 1, the upper end of the fixing sleeve 4 is located inside the fixed head 1, and the strip hole 7 on the fixing sleeve 4 is compressed, so that the fixing sleeve 4 holds the sand knife tube 2 tightly, and the sand knife tube 2 is fixed inside the adapter 3 and the fixed head 1, so as to prevent the sand knife tube 2 from shaking.

[0020] like Figure 2 As shown, in order to ensure the sealing of the sand knife tube 2 during installation, a gasket installation cavity 8 is provided in the middle of the adapter 3, and a gasket 9 is installed inside the gasket installation cavity 8. After the adapter 3 is connected to the gun head rod 5, the gun head rod 5 can press the gasket 9; and gasket grooves 10 are provided on the front and back sides of the gasket 9, and the gasket grooves 10 are connected to the through hole in the middle of the gasket 9.

[0021] like Figure 1 and Figure 2 As shown, the front end of the sand cutter tube 2 is a truncated cone structure 11. After the sand cutter tube 2 is installed, the truncated cone structure 11 extends into the opening at the end of the fixed head 1, and the rear end of the sand cutter tube 2 is provided with a bucket-shaped opening 12. The front end of the bucket-shaped opening 12 is aligned with the internal pipeline of the sand cutter tube 2, and the rear end of the bucket-shaped opening 12 is installed in the gasket groove 10 of the gasket 9, which can reduce the water resistance and allow all the liquid to enter the sand cutter tube 2.
