[0044] As Figures 11 to 13 shown, the installation bottom box 1-1 is hollow, and the installation bottom box 1-1 serves as a floating body of the small fountain module. An arc-shaped recess 1-1-5 is provided at the connection between the installation bottom box 1-1 and the connecting component 3. The connecting component 3 includes a connecting profile 3-3 provided with a plurality of arc-shaped portions 3-3-1 embedded in the arc-shaped recess 1-1-5, a connecting shaft 3-4 provided on the lower surface of the arc-shaped recess 1-1-5 of the installation bottom box 1-1 and remaining in a state of passing through the arc-shaped portion 3-3-1 during the angle adjustment process, an arc-shaped tooth groove plate 3-5 sleeved on the lower end of the connecting shaft 3-4, a locknut 3-6 provided on the lower end of the connecting shaft 3-4, and an arc-shaped rack portion 3-7 provided on the lower surface of the arc-shaped portion 3-3-1 and mating with the arc-shaped tooth groove plate 3-5. When the installation bottom box 1-1 moves upward under the buoyancy of water, the arc-shaped tooth groove plate 3-5 meshes with the arc-shaped rack portion 3-7 to achieve limiting; when the installation bottom box 1-1 is pressed downward to overcome the buoyancy of water, the arc-shaped tooth groove plate 3-5 is separated from the arc-shaped rack portion 3-7.

[0045] As Figures 11 to 13 shown, an arc-shaped backing plate 3-8 for supporting on the arc-shaped recess 1-1-5 is telescopically provided on the arc-shaped portion 3-3-1. A receiving groove 3-3-2 for the arc-shaped backing plate 3-8 to be embedded is provided on the arc-shaped portion 3-3-1. A telescopic shaft 3-9 passing through the receiving groove 3-3-2 is provided on the arc-shaped backing plate 3-8.

During the upward floating process of the installation bottom box 1-1, the arc-shaped tooth groove plate 3-5 and the arc-shaped rack part 3-7 are engaged to prevent the installation bottom box 1-1 from rotating; during this process, with the installation bottom box 1-1 as a floating body, it has the effect of conveniently adjusting the angle of the nozzle body 2-5-2 of the small fountain module. At the same time, the setting of the arc-shaped recess 1-1-5 and the arc-shaped part 3-3-1 of the connecting profile 3-3 can achieve axial positioning.

[0048] After the connecting bottom box moves upward as a floating body, there is a gap between the connecting bottom box and the connecting profile 3-3. Through the setting of the arc-shaped cushion plate 3-8, the telescopic shaft 3-9, and the compression spring 3-10, when the arc-shaped tooth groove plate 3-5 is engaged with the arc-shaped rack part 3-7, the arc-shaped cushion plate 3-8 is supported on the arc-shaped recess 1-1-5 under the action of the compression spring 3-10; when the arc-shaped tooth groove plate 3-5 is separated from the arc-shaped rack part 3-7, the arc-shaped cushion plate 3-8 is embedded in the accommodation groove 3-3-2, thereby achieving a certain support for the connecting bottom box; at the same time, an arc-shaped limiting groove 3-5-1 for the telescopic shaft 3-9 to be embedded and not affecting the rotation of the arc-shaped tooth groove plate 3-5 is provided in the middle of the arc-shaped tooth groove part, so that the installation angle of the arc-shaped tooth groove plate 3-5 will not rotate.
