[0004] However, the prior art as mentioned above still has the problem of poor connection and positioning effect between the shell and the inside of the pull-out head. For example, in the above patent, a snap-fit ​​structure is set to assemble and install the pull-out head by snap-fitting. Although this method is convenient for disassembly and assembly, it is not convenient to quickly locate the corresponding position between the shell and the internal structure during installation. Improper installation will cause the shell to be unable to control the opening and closing of the pull-out head, requiring multiple adjustments, which affects the efficiency of disassembly and assembly.

[0021] Furthermore, a plurality of the water outlets are provided with water outlet holes on one side opposite to the water outlet panel.

[0022] By adopting this technical solution, the water flow can be controlled more accurately to meet different usage requirements.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] 1. The injection-molded shell structure of the pull-out head is provided with a connecting mechanism, and the cooperation of the center positioning block and the positioning groove ensures the precise positioning between the shell and the pull-out head body, thereby improving the accuracy and reliability of installation.
